SPECIFICATION forming part of Letters Patent No. 722,404, dated March 10, 1903.

Application led April 22, 1902.

To LZ wiz/01u it nutty concern:

Be it known that I, HARRY O. GAMMETER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Duplicating-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

In business it is often desirable to reproduce circular letters or similar written matter in large quantities, and my invention relates to machines for this purpose. It is especially adapted for duplicating letters so that they t5 have all the appearances of having been written upon a type-writer, with the incidental advantages.

That form of the machine to be described comprises two drums, distinguished as the 2o printing-drum and the supply-drum. The former is adapted to have type set up upon it and is operated so that their impression is taken upon a sheet of paper. The supplydrum, as its name indicates, carries the'type when not in actual use. These two drums are on the same axis and are so constructed that they enable the type from the supplydrum to be passed to the printing-drum, automatic mechanism being provided for this 3o purpose and for assisting in the proper distribution of the type upon the supply-drum after the operation.

The invention consists in a certain construction and combination of parts to be more fully described hereinafter and deflnitelyset forth in the claims.

In the drawings, which fully illustrate my invention, Figure l represents a central crosssection of the same in a vertical plane. Fig.

4o 2 represents the mechanism in side elevation, a portion of the frame being broken away to more fully disclose the interior construction. Fig. 3 represents the mechanism in plan, a portion being broken away,asindicated. Fig.

connection with this invention. Fig. 7 repre- 5o sents, on an enlarged scale, a det-ail of a connection used in this machine. Fig. Sis a detail elevation of certain feeding mechanism,

the part in connection therewith being brokenA away. Fig. 9 is a plan of a keeper used in every line. Fig. l0 is a detail elevation, on

an enlarged scale, of the inner ends of certain feeding-racks; and Fig. 11 is a detail elevation of a rock-wheel.

Referring to the parts by numerals, 1 represents the frame, which comprises a substantially horizontal base or bed 2, provided on either side with upwardly-projecting standards 3 4, preferably formed integrally with the base. Upon these standards is mounteda Vhorizontal shaft 5, which is provided at its` outer extremity with a gear 6, which is rigid therewith. Upon this horizontal shaft 5 is mounted a rotatable drum 7, which will be described more in detail hereinafter. The inner extremity of this shaft is provided with another drum 8, which is rotatably mounted and is capable of a limited sliding movement upon the shaft for a purpose which will appear. v

The drum 7cornprises, substantially, spiders or ends 124, which are connected by a cylindrical portion or body 9. This cylindrical body is-not, however, continuous, but is cut away upon its rear side, as indicated at 10. Its outer face 11 is constructed substantially as indicated in Fig. 6. It is provided with longitudinal channels or ways 12, which extend from end to end and which are formed, preferably, by means of T-shaped strips 13, set tightly into narrow longitudinal grooves 14 inthe face of the drum. Within these channels type 15 are carried, and each type is provided with grooves 16 at either side, which receive the slightly-projecting T-heads 17 of the aforesaid strips 13, wherefore they are maintained within the recess. This drum 7 is adapted to be rotated by means of a gear 18, which is rotatably carried by the aforesaid standard 3 and provided with a crank or handle 19.

Spools 2O carry between them a web or band 21, which passes around the channeled face 9 of the drum 7 and lies over the printingfaces of the type 15, which project, as indicated, slightly above the face of the drum. The Width of this band is so great that it substantially covers the printing-face of the drum. It is constructed of some suitable transfer material, such as fabric, which has absorbed ink and is similar to an ordinary type-writer ribbon.

One end of the drum is provided for a portion of its periphery (which portion corresponds substantially with the printing-face of the drum) with gear-teeth22, which are adapted to engage with a rack 23 on the carriage 24, which is mounted horizontally in the aforesaid bed 2. I

Now from the construction described it Will be readily understood that when the crank 19 is turned the drum 7 will be rotated, and at the same time the carriage 24 will pass beneath the drum and will slide toward the opposite end of the bed, and when the carriage passes in this manner a platen 25 on the carriage will be impressed by the projecting faces of the type carried on the face of the drum 7; but it will be remembered that the band 2l, which has already been described, passes about this drum 7 and rests upon the printing-face of the type, and hence if a piece of paper were placed upon the platen 25 it would be impressed by the type and written matter would be produced corresponding to thatwhich had been set up upon the drum. This platen projects above the face of the carriage, as indicated, and is preferably made of rubber of slight elasticity. In order to prevent any possibility of the teeth upon the rack 23 jamming and not coming into proper mesh with the gear-teeth 22 on the drum, I prefer to omit one of the teeth of the rack, as indicated at 57.

In Figs. 1 and 2 the construction of the bed 2and the arrangement of the parts in connection with the carriage are most clearly shown. It will, be observed that on its inner side the bed is provided with longitudinal horizontal guide-bars 26, and the aforesaid carriage 24 rests upon their upper faces and between the inner faces of the bed 2. These bars 26 are provided at intervals along their length with inclined slots 27, through which screws 28 pass and secure them to the side of the bed.

It is desirable that the carriage should be capable of a certain vertical adjustment, so that the position of the platen 25 may be that which is adapted for producing the best impressions of the type upon the sheet. For this purpose the aforesaid inclined slots 27 were provided. By means of adjusting-screws 29, mounted longitudinally in the ends of the bars 26 at the end of the bed, this adjustnient of the carriage is effected. This construction is most clearly shown in Figs. 2 and 3. Check-nuts 30 prevent accidental displacement of the carriage after adjustment. Upon its lower side the carriage is provided with small brackets or clips 31, which project so as to engage the lower face of the aforesaid guide-bars 26, so that the carriage 24'is held down upon the bed. AV

taken place the rack 23 will pass out of engagement with these teeth, whereupon it will be returned to the normal and extreme position in which it is shown. The arrangement, however, is such that this return does not take place until the carriage has passed sufficiently far beneath the drum 7to take the impression of all the matter set up upon its face. l

In order'to prevent any ill effects which might arise from the sudden or violent return of the carriage 24 by the spring 32, the dash-pot 33 is provided, preferably secured to the end of the bed 2, as indicated. It consists, substantially, of a horizontal cylinder 34, in which is mounted a loosely-fitting piston 35, the rod 36 of which projects horizontally and is adapted to abut the downwardlyprojecting bracket 37, carried by the lower side of the carriage 24. A spring 3S operates .to lforce this piston outwardly to an extreme position when the table has passed to its outward position. By this arrangement the table is brought to rest quickly, but gently and easily, so that no jar is given to the mechanism.` It should now appear that if the handle 19 were continually rotated in one direction the drum 7 would be turned and the table would be made to pass beneath the drum in rapid succession, being always returned by the spring 32 as soon as -it becomes free of the gear-teeth 22. Hence if blank sheets be laid upon the platen one at a time they will receive printed matter as fast as the drum can be rotated. Means are provided for removing each of these sheets after it has been impressed. This is preferably accomplished by means of aVvacuum-cup 39, which is carried by an arm 40, as indicated. This arm 40 is itself carried upon the rock-shaft 41, which passes across above the bed of the Inachine, being supported in brackets 42, secured to the sides of the bed. At one of its extremities, preferably the one which is on the same side as the rack, the rock-shaft 41 carries a trip-lever 43,;which inclines downwardly, as indicated, so that it may contact with a pin ,44, which projects outwardly from the side of the rack 23. ,When this pin presses the lever upward, the vacuum cup, which is formed, preferably, ofrubber, is depressed and forced downwardk upon the printed sheet lying upon the table. When the table commences to moveback to its normal position,

IOO

the vacuum-cup prevents the return of the sheet of printed matter, and when the table passes from beneath it the Vacuum is broken by air entering the cup around its edges. The printed sheet falls upon the plate 45, which extends across the bed at this point, as indicated.

In order to provide for changing the time which the vacuum-cup is depressed, the rack 23 is provided with several holes 46 at diderent positions, all of which are adapted to receive the aforesaid pin 44. Proper alinement or register` of the paper is effected by providing dat strips 47 48, which are arranged to move in parallelism respectively with the longitudinal and transverse edges of the carriage. They are pivoted to the edge of the table on parallel arms 49.

Provision is made for feeding the band 2l automatically between the aforesaid spools 20. For this purpose, as clearlyindicated in Figs. 2 and 8, the extremity of the spindle of each spool is provided with a gear-wheel 50, which lies at the end of the drum 7, and an arm 51, which is pivoted to the drum at 52, carries a small pinion 53, the teeth'of which are adapted to mesh with the teeth of either of the gears 50. This pinion 53 is rigid with a star-wheel 54, and if the arm 5l be secured in the position shown in Fig. 2 once in every revolution of the drum the star-wheel will come into contact with the pin 55, carried by the standard 4, and this operates to give the star-wheel a rotation, which is transmitted to the spools and eects an intermittent feeding of the band 2l. If the arm 5l be thrown to such a position that the starwheel will appear where it is shown in dotted lines in Fig. 2 during the rotation of the drum, the star-wheel will now contact with a second pin 56, and this contact will now operate to produce an intermittent feeding of the band in the opposite direction, and it will be observed that at the moment this advance is given to the star-wheel the printing-drum is not in contact with the platen, and hence no resistance is offered to the movement of the band. A thumb-nut 120 affords means for locking the arm 5l in the positions described.

Proceeding now to a description of the mechanism for setting up the type in the channels of the printing-drum, it will be observed that the supply-drum 8, to which reference has already been made, is provided with channels 59, which are in all respects similar to the channels 12,formed upon the face of the printing-drum 7. Ir. these channels are carried type arranged in rows according to the letters or characters which they represent, as will be readily understood.

Referring especially to Figs. l and 4, it will appear that the upper extremity of the upright 3 is provided with a horizontal slot 60, which is of substantially the same depth and width as the channels of the two drums 7 and 8. By rotating the drums any channel of either drum may register with this slot. Hence it will appear that if the printing-drum were held so that any particular slot or channel remained in register with this slot the supply-drum could be turned to successive positions, so that the different type-rows would be brought into alinement with the slot. Briefly, that is the way the type are set.

The inner ends of all the channels of the supply-drum are closed by a disk 6l, which rests against the inner face 64 of the supplydrum in the manner indicated and is maintained against it by a helical spring 62, which thrusts against it around its center. This disk, however, does not turn with the supply-drum, and in order to enable the type to pass it it is provided with an opening 63,which alines with the aforesaid slot 60. The inner face of the supplydrum is provided with small openings 65, which are adapted to receive a small pin 66,'which projects outwardly from the side of the upright standard 3. There are as many of these openings 65 as there are channels in the supply-drum, and when any channel of the supply-drum is in alinement with the aforesaid slot 60 an opening corresponding to this channel is then in alinement with the aforesaid pin 66. The extremity of this pin 66 is preferably conical or pointed, as shown at 67, and lies close to the face of the supply-drum, so that a slight movement of the su pply-drum along the shaft 5 inwardly would operate to bring the pin and opening into engagement. From this arrangement it will be understood that when the supply-drum has been turned to bring a certain channel substantially into alinement with the slot 60 it is made to aline exactly with the slot by moving the supply-drum laterally along the shaft, so that the pin and recess engage in the manner which has been described. After this has taken place everything is in readiness to pass the matrix through the slot and into the channel of the printingdrum.

Mechanism is provided for utilizing the lateral movement of the suppiy-drum to effect the automatic passage of the matrix through the slot 60. For this purpose a movable pin 68 is mounted horizontally in the upright 3, and this pin has an enlarged head 69, which is received by an opening in the aforesaid disk 6l in-the manner shown in Fig. l. Its inner extremity is provided with a slot 70, through which passes an upright lever 7l, attached to it by the pin 72. The lower extremity of the lever is pivoted to the upright 3 at 73, the upright being provided with a vertical recess 74 to receive it. Just above this lever 7l is mounted a rock-wheel 75, the lower side of which is provided with gearteeth 76, which are adapted to mesh, as indicated, with gear-teeth 77, provided on the upper extremity of the aforesaid lever 71.

IIO

The upright 3 carries, as indicated, avhorizontal feed-bar 78, which extends longitudinally of the machine above both the supplydrum and the printing-drum. One of its ex.

tremities rests upon the top of the standard 4, where itis secured bya strap 121'. That portion of this bar which lies over the supply-drum supports a horizontal supply feedrack 80, the lower edge of which is provided with teeth 8l, which are shaped substantially as shown, and this feed-rack is provided withI slots 82, which surround pins 83, carried by the aforesaid horizontal bar. As indicated in Fig. 7, one extremity of these slots inclines downwardly, so that if the feed-rack were given an inward longitudinal movement with respect to the feed-bar it would be lowered and then advanced horizontally. When this takes place, the teeth 81 engage with the upwardly-projecting teeth 84, which are integral with the chaser 85, carried in each of the channels of the supply-drum. These chasers are formed at their bases similarly to the type, so that they are retained by the channels. the innermost matrix in each row, so that they can operate to force the entire row outwardly when the feed-rack is actuated. A spring 86 normally constrains this feed-rack in an extreme position, and an adjustingscrew 125, carried by it, is adapted to contact with the extremity of the feed-bar and limit the advance of the rack. In this manner the amount of advance of the chaser can be accurately determined beforehand, and it is needless to say the amount' of this advance should be exactly the width of one matrix.

That portion of the feed-bar which lies over the printing-drum is provided with a horizontal face 86, as indicated in Fig. 5,and upon this face rests a distributing feed-rack 87, which is in many respects similar to the supply feed-rack, which lies over the drum. As indicated, however, the teeth 88 upon this feed-rack are upon its upper edge and inclined toward the supply-drum. The thickness of this rack is such that its upper face is flush with the face of the feed-bar, as indicated. Upon this feed-bar 78 and surrounding the rack is mounted a rider 89, which is provided with a small block 90, having teeth on its lower face which project downward and incline in the opposite direction from those of the feed-rack. The construction of this rider will be described more in detail later. Its f unction is to assist in bringing about the removal of the type from the channels of the printingdrum when they are being distributed back upon the supply-drum. To this end the rack 87 is provided with pins 91,which project into a slot 92, formed in the feed-bar. These slots are inclined downwardly at one extremity in a manner similar to the slots in the feed-rack over the supply-drum. Now if this feed-rack 87 were given a movementin the direction of the supply-drum the pins 91 which it carries would ride up in the slots 92 and elevate the rack, after which it would move on horizontally. The rise ofthe rack is sufficient to bring about the engagement of its teeth with the teeth carried by the block of the rider As stated, one is provided behind mounted the aforesaid rock-wheel 75.

and slides the rider along the feed-bar 7 8. Arrangements are made for limiting the amount of advance of this rider, as indicated at 93, which arrangements are similar to those yadopted at the opposite extremity of the feedbar, and which have already been described.

At a point substantially near its middle the distributing feed-rack 87 is provided with a recess 94, as clearly shown in Fig. 5, in which is mounted a small helical spring 95, which constrains the rack normally in an extreme position in which it is shown.

Proceeding now to a more detailed description of the rider and mechanism connected with it, and referring especially to Fig. 5, it will appear that this rider includes a yoke 96, surrounding the feed-bar, an d having beneath the feed-rack an enlarged head 97,which head is provided with a small vertical opening or bore 98. In the bore is mounted slidably'a small bolt 99, provided with a laterally-projecting pin 100, which passes out through a vertical slot 101 in the head, as indicated. This slot is further provided at its upper extremity with a lateral notch or recess 102, into which the aforesaid pin may be moved, so that the bolt will be maintained in an elevated position. The pin aords means for raising the bolt, as will be readily understood.

Achaser 103 lies in the channel just below the rider, and it is yprovided with a vertical v from the drum as far as `the face of the type,v

so that they do not operate to `produce impressions through the inking-band.

Recurring again to the mechanism for automatically moving the rack for the purpose of effecting the feeding of the type, it will appear that the upright 3 is provided with an upward extension or head 105, and an arbor 10G passes through this head and the aforesaid feed-bar 7 8. Upon this arbor is loosely As viewed in Fig. 4, the right-hand extremity of this arbor 106 carries a short radial arm 108, which arm is provided with a laterally-projecting pin 109. This pin 109 is adapted to pass through a small elongated opening 110 in the inner extremity of the feed-rack, so that its tip may be received by openings 111 112 in the aforesaid rock-wheel. In Fig. l this arm is shown so that it has pinned together the distributing feed-rack and the rock-Wheel. Now evidently any movement of the aforesaid lever 71 will be transmitted through the rock-wheel to the distributingrack. Such a movement is brought about by the inner face 64 of the supply-drum impinglOO IIO

spaces or ing with the head of the horizontal pin 68,

vand it will be remembered that the supplydrum is capable of this horizontal movement upon its shaft.

When the parts are connected in the manner shown in Fig. 1, the mechanism when actuated will of course operate to move all the type in the channels bodily toward the slot 60. It is needless to say that, as before, the amount of movement is exactly one toothspace and the same as the width of one type. A small helical spring 114 constrains the aforesaid arbor; but the same may be withdrawn by means of the head 115, and the pin 109 will be removed, so as to disconnect the distributing-rack S7 from the rock -wheel, whereupon the radially-projecting arm may be thrown to an opposite position, so that its pin may connect the feed-rack of the supplydrum with the rock wheel 75. If such a change were made, a movement of the lever 7l, produced by the sliding of the supplydrum, would evidently then actuate the feedrack of the supply-drum and eiect an ad- Vance of type in one of its channels.

In order to hold the printing-drum in a fixed position in the manner described, the standard 3 is preferably provided with a second slot 116, in which is slidably mounted a small lock 117. The dimensions of this second slot are substantially the same as those of the slot 60, and the distance between the two slots is the same as that between any two adjacent channels, so that when the slot 60 is in register with one of the channels of the printing-drum the slot 116 will then be in register with the adjacent channel. Evidently this lock 117 may secure the drum against movement.

The arrangement of the dierent characters or type carried by the supply-drum will be that which is best adapted for facilitating the operation of setting them up upon the printing-drum. It is found in practice, however, that this arrangement is preferably not in alphabetic sequence, for it is desirable to place those characters which are used with most frequency so that they can be brought into alinement with the slot 60 without being obliged to turn the supply-drum through a great angle. For instance, channels with characters like the vowels a and e would be distributed with comparative frequency on the face of the supply-drum, while channels occupied by letters which are not used frequently, as the letters x and z, would of course notappear upon the face of the drum with the same frequency as the others. With such an arrangement the operation of alining the channel carrying any particular character with the slot 60 is much facilitated, and in order that the operator may be able to tell at a glance what channel or character is alining with the slot a rim 118 is provided at the outer edge of the supply-drum which carries letters upon it corresponding to the channel opposite which they are located.

As indicated in Fig. 1', this rim 11S has an annular portion 119, which closes all the outer ends of the channels of the drum.

From the foregoing description the operation of setting up the type upon the printingdrum and distributing them again into their proper channels upon the su pply-drum should be clearly understood. However, it may be said that in setting up the type on the printing-drum the band or transfer-ribbon which passes over the printing-face of the drum is first removed. This is done by winding the entire band upon one of the spools, and for this purpose the extremity of the spindle may be squared, as indicated at 122, to engage with a key or crank. The printing-drum is then turned so as to bring that channel which is to carry the rst line in alinement with the slot, and it is locked in this position in the manner described. The supply-drum is then manipulated so as to bring any desired letter or character which it carries into alinement with the opposite end of the slot, whereupon the automatic feeding mechanism having been properly connected the lateral sliding movement of the supply-drum efects an advance of one type-matrixinto the slot. This operation 'continuing the type being set up crowd each other back, the innermost member being in contact with the distributingchaser. When a complete line has been set up in thisI Way, the matrices which are then lying in the slot 60 are pushed through by the hand of the operator with a pencil or similar pointed article, and the entire row is moved over against the closed extremity of the channel. When a line has been set up in this manner, the keeper 126, which is shown in plan in Fig. 9, is placed in the slot behind the last type-matrix of the line. At their bases these keepers are constructed similar to the bases of the matrices, so that they run in the channels and are retained therein. They are carried upon the supply-drum in the same manner as the regular type characters and type-spaces and are automatically fed from the supply-drum in the same manner. As will appear in Fig. 9, they are provided with a bifurcated extremity 123, and the bifurcations are resilient and tend outwardly, so that they will retain the follower in the channels against movement by a slight force.

The length of the distributing-Chaser is determined by the amount of margin desired at the left hand of the finished sheet. Where a greater margin is required for any particularl line, this is obtained by utilizing the ordinary type-spaces, which are carried by the supply-drum, as stated.

The distance between the channels of the printing-drum is substantially the same as that between successive lines of type-written matter, where the lines are printed asclosely as possible. In ordinary work, however, only the alternate channels are set up with type, the intermediate channels being ignored.

IOO

With the mechanism described it is possible to set up and reproduce in large quantities and at a rapid rate the body or principal portions of circular-letters or similar printed matter, after which the individual addresses required for each letter may be inserted by means of an ordinary type writer having similar type characters to those used by the machine and a similar ribbon. In this manner a letter may be reproduced which has all the appearances of having been type-written, which is very desirable.

It should be understood that the bolt99 in no way interferes with the vrotation of the printing-drum, because, whenever necessary, it can be raised and locked in the elevated position, as described, where it will be out of danger of contact with the face of the drum.
