FOLDING AND MARKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 649,931, dated May 22, 1900.

Application filed May 15, 1899. Serial No. 716,808. (No model.)

To all 2072,0711 it may concern.-

Be it known that I, NATHAN HAYWARD, of B rockton,in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Folding and Marking Machines, of which the following is a specification.

This invention has relation to machines for folding the edges of pieces of flexible material, such as the quarters and other parts of shoe-uppers.

The invention has for its object to provide improvements in the folding machine described in United States Letters Patent No. 628,798, granted to me July 11, 1899, the improvements relating particularly to the means for operating the former, around which the edge of the material is folded, and to the treadle mechanism whereby the former is depressed and the folder which folds the edge of the material over the former is elevated.

The invention also has for its object to pro vide means in an upper-folding machine for marking one side of the shoe-upper to form a guide which shall enable the operator to accurately locate the line of stitching which is commonly placed at a distance from the folded edge of ashoe-quarter to ornament the same.

With these ends in view the invention consists in the novel features of construction and arrangement which I shall now proceed to describe and claim.

Of the accompanying drawings, Figure 1 represents a side elevation, partly in section, of a folding and marking machine constructed in accordance with my invention. Fig. 2 represents a plan view thereof with parts broken away. Fig. 3 represents a vertical sectional View thereof, illustrating also the treadle mechanism by which parts of the machine are operated. Figs. 4: to 8, inclusive, represent detail sectional views on an enlarged scale, showing different positions of the folding mechanism. Fig. 9 represents a detail plan View on a reduced scale, showing a shoe-quarter after being folded and marked.

The same reference characters indicate the same parts in all the figures.

Referring to the drawings, a designates a stud or stem a, on which is journaled a rotary frame I), supporting on opposite sides of its axis of rotation two folding mechanisms, similar to each other in construction and arrangement, and two work-supporting tables 0 0. Between the tables 0 and the central stem a the frame Z) is recessed at I) b to receive two folders d cl, which are given a vertical and horizontal movement and cooperate with f0rmer-blades e e in folding the edge of the work. The former-blades 6, tables 0, and folders (I have their edges curved to conform to the curvature of the work.

The folding mechanisms being alikein construction, a detailed description of one of them will suffice. The former-blade e of each is attached to the lower side of a bar e, forked at its end and guided on rods 6, which are secured in Vertical posts a on both sides of the machine. Said posts are guided in sockets in the frame I) and are normally projected upwardly by means of springs, Fig. 1. At their lower ends the posts are connected by a yoke, from the middle of which a hooked plate 0 projects downwardly in position to be engaged by a treadle -rod 6, mounted in a vertical bearing in the base a. The depression of the rod 6, when in engagement with the hooked plate 6 causes the former-blade c to descend upon the work supported on the table 0 and to clamp said work to the table.

Pivotally mounted on the posts 6 e are arms e 8 having slotted ends, which are engaged by pins e on the bar 6', to which the former-blade c is attached. On the hubs of the arms c above the latter, are two longer arms e c interlocking at their ends by means of a slot in the arm e occu ied by a pin a on the arm a. The arm e carries a roller 6", adapted to engage a cam g which is formed as a lug on the upper side of a plate 9. Said plate is clamped to the upper end of the stem a by a plate a bolted to said stem, the hub of the plate 9 engaging a shoulder on the stem. By this arrangement the cam g operates against the roller e when the frame I), carrying the folding mechanisms, is rotated, causing the'interlocked ends of the arms 6 e to move outwardly, whereby the former e is moved in an outward direction and is withdrawn from the fold in the work. Springs 6 c surrounding the rods 6 and interposed between the posts 6 and the ends of the bar 6, operate to return the former 'e inwardly.

The folder d consists of a plate mounted on a folder-carrier d, which is carried by vertical posts 01 connected by a yoke d at their lower ends. Said posts pass through sockets in the frame 12 and are surrounded by springs therein which normally depress the posts and the folder-carrier. A cam lug or boss 01 on the yoke d is adapted to become positioned over a treadle-rod 01?, to which an upward movement is given at the proper time, cansin g the folder-carrier d to be elevated. When the folder (1 has risen far enough to"clear the edge of the former-blade c, it becomes released from two pins d d, engaging it at their ends, and is automatically projected outwa'rdlyby springs, causing the edge of the work to be folded over the former-blade. Upward pressure on the rod at being then discontinued the folder d is pressed down wardly upon the work by the tension of the springs surrounding the posts 1 The formerblade is then withdrawn, as described, and the 'fold is held under pressure. The release of the work from the folder is effected during the rotation of the frame I) by the engagement of' the cam-boss d on the yoke 01" with a'roller-stud d on the base a, which ex-.

ertsan upward pressure on the folder-carrier and lifts the folder clear of the work, whereupon said folder is retracted by the engagement of a cam g, formed as a lug on the under side of the plate g, with a roller-stud d", affixed to the upper side of the former d, andis again brought into engagement with its release-pins d v r I provide an improved treadle mechanism by which, with the operation of a single treadle, both of the rods d and e are moved to actuate their respective mechanisms. 7L represents a lever f ulcrumed at h to a fixed support and slotted at its end to engage a pin e on the "rod 6 and 11 represents a second lever fulcrumed at i to a fixed support and connected at its end with the rod d The lever h is connected by a link 7' attached to the lever between its fulcrum and its pointof connection with the rod a, with a treadle j, and at It said lever is provided with a stud projecting laterally over the heel of-the lever 'i and adapted to abut the head of a screw '5 which is capable of vertical adjustment in the heel of said lever i and is adapted to be locked in place by means ofa lock-nut 1 The depression of the treadle j causes the two levers h 'i to be oscillated in opposite directions, the lever h being swung downwardly and depressing the rod '6 and the lever i being swung upwardly by reason of the engagement of the stud 72, with its heel, thereby ele- Vating the rod 61''. Such depression of the treadle therefore effects the operation of both the former e and the folder at when the frame I) isproperly positioned to bring the hooked plate e and cam-boss d into operative relation with the two treadle-rods. The pin-andslot connection of the lever h with the rod 6 compensates for the extra movement which said lever h undergoes, and a spring c ,interposed between'the lever and a nut e on the lower end of the rod e restores the levers and rods to their normal relation after action. A

the position normally occupied by the former blade e, so that when the latter descends upon the work it presses the work against the'ends of the pinsff and forms a row of marks or indentations upon the under side of the work. These indentations are shown at a in Fig. 8, in which to represents the shoe-quarter, and it will be seen that they occupy a place corresponding to the position of the line of stitchin g subsequently placed on the shoe-quarter. The pins f f collectively constitute a marker, whose projection above the surface of the work-supporting table is slight, being insufficient to interfere with the proper positioning of the former 6 when the work is inter posed between said former and the table.

The cycle of operations of the above-described machine is as follows: The operator moves the frame I), if necessary, to bring one of the folding mechanisms in front of him, and said frame is automatically stopped when it reaches the proper position by the'engagement of the roller-stud d on the folder which is about to be called into operation with an abutment ortooth g projecting from-the hub of the plate 9. The backward rotation of the frame is prevented by the coaction of the rear side of the cam-boss d on the operative side of the machine with the roller-stud d on the base a. The work is now placed on the table 0 with its inner edge overlapping the folder d, and the treadle j is depressed, causing the former-blade c to descend upon and clamp the work to the table and bypressing said work against the pinsf to mark the under side of the work, as described. The folder d meanwhile rises and is projected over the former-blade c, causing the edge of the work to be folded around said blade. The treadle j is then released, and the frame I) is rotated around to the right, its rotation being permitted by reason of the fact that the roller-stud (Z has moved out beyond the quired with the machine described in the patent hereinbefore alluded to. The other folding mechanism is now brought in front of the operator and a fresh piece of work inserted therein, while the fold in the piece of work just operated upon is left to set by the pressure of the folder and the heat supplied by steam-pipes attached to the machine. The rotation of the frame to bring the second folding mechanism into position causes the roll (Z on base a to engage boss (I of said mechanism and lift its folder-carrier, and the cam y then acts on the roller-stud d to retract the folder d, releasing the work which may have been under pressure in said mechanism. Figs. 4: to 8, inclusive, show the successive operations of the parts during the folding operation, certain portions of the machine being omitted in these figures for the sake of clearness.

I do not confine myself to the exact construction and arrangement hereinbefore described, as the same may be considerably modified without departing from the spirit of the invention.
