To all whom it may concern.-

Be it known that I, CHARLES 7. KING, of

Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Hand Tacking- .Machines, of which the following is a full,

clear, and exact description.

This invention relates to a machine for antomatically driving tacks or nails one after another, and intended to be used more especially in connection with a machine for lasttical section; Fig. 3 aplan view. Fig.4 represents a detail plan viewbelow line 44 Fig. 2;

Fig. 5 a detail plan, and'detail horizontalsection, below line 5-5 Fig. 1."- Fig. 6 is a detail plan view. Fig. 7 isa vertical cross'section on line 7-7 Figs. land 2. Figs. 8 and 9 are perspective views of one of the parts intwo different positions. Fig. 10 is a detail horizontal section just above the horizontal section'of' Fig. 5. Fig. 11 is a detailpfront or end view. .Fig. 12 is a detail plan view. Fig. 13 is a detail side view of one ofthe parts;

In the drawings A represents the body of. the machine tacker, B a handle for grasping and holding it by the hand,O a receptacle for l the tacks consisting of a vertical-cup, which is adapted to screw on to the upper end of the body as at a, open at its bottom, and having 1 two horizontal partitionsD, E, therein which freely fit the internal sides of the cup and'are connected together by a central post F, which extends down below the lower partition E, and has secured to its lower end the lower end of a curved tube G which at its upper end is secured to: the lower partition at one side or edge of the partition and at such place has an opening H communicating with the chamber of the tube, the tube having a longitudinal open slot K, in its side extending throughout its length in a spiral direction and where the tube is secured to the partition, the partition is cut away outside of the diameter of the tube in a small V-shaped opening L, over such -spiral slot.

' The upper partition D has an elongated opening M at one side as shown in Fig. 3, and it has four vertical pins or wires 19, which pass through'it, extending-above and below the partition, the upper partition also having a central vertical handle N by which the partitions can be reinoved t'rom the receptacle whendesired; the receptacle has a cover P which fits over its upperend'to'close it, and it is held in place by a four armed spring plate Q secured at its center to the inner side of the cover, each arm being bent down as at d and of the receptacle. A pin e projects radially and horizontally from the inner side of the recepforming a spring, to bear against the inner side tacle and the upper partition has an open slot f 7a in its edge which when the partitions, and more particularly thetube or spout, is'in the proper place engages with the pin and prehaving an opening or slot h in its edge which enables it to freely pass by or over the pin e. Thehole M through the upper partition is on the opposite side of the receptacle to the opening H in the lower partition communicating with the spirally slotted spout or tube.

In the body is an inclined raceway R which is shown in longitudinal central section in Fig. 2, and in plan in Fig. 5, this raceway down to the point m being in the body of the machine, and it is continued in'a block S which is inserted in a recess n in the machine body. This raceway consists of a longitudinal vertical groove 1" and in the body each side extends upward from the groove being inclined as shown in cross section in Fig. 7.

Opposite the lower end of the raceway in the block S is a small cylinder or block T which is arranged to make a partial turn, or

revolution or swing back and forth on'apivot u in a chamber or socket o in the block but block S partially over the socket, by a plate 3 secured in a depression a in the under side of the block, which plate and the portion to of the block serve to hold the pivot u for the cylinder.- Across one side of the cylinder T is an opening I) in which is a vertical pin (1 against which pin is arranged to bear a flat spring 6 secured in a recess in the side of the block by a screw.

g is a vertical slot in the side of the cylinder which when it is in its normal position is opposite to or coincident with the end of the raceway groove 7'. In this cylinder just below its top is a horizontal transverse open slot it one end of which opens into the farther side of the vertical slot g and the other end terminates in an opening m in the upper end of. the cylinder, below which last opening m is another deeper open horizontal slot n. Against its shoulder r is arranged to bear the round end 15' of a pin V arranged to move back and forth in a horizontal socket u in the head U of the body, and in an opening 1) in the block S as shown in section in Fig. 5 more' particularly.

In the block S diagonally back of the opening '2) in which the cylinder moves and communicating therewith, and just back of the lower end of the raceway groove 1', is a vertical opening W which extends down to and communicates with an inclined passage A as shown in dotted lines in Fig. 2. Extending inward horizontally into the cylinder socket 'v is a thin pointed piece, arm or stripper a of the block S which horizontally is in position to project freely into the horizontal opening 71 in the cylinder as shown in Fig. 10.

Adapted to slide up and down between two arms B of the head U is the tack driver, plunger or bar C consisting of a portion 1) substantially oblong in cross section, its lower portion being in the form of a rod or spindle D which extends down through a socket d in the head of larger diameter than the rod and open to its outside at c bya space smaller than the socket but large enough for the rod D to be moved out through it, the lower end of the driver rod D extending down into asocket E in the foot portion Fof the head to freely slide up and down therein. The driver has two shoulders f which abutagai'nst the under sides of the arms Bot' the head as a stop to the upward movement, and the lower end 72 of the square portion abuts against the shoulder 'm of the head as a stop to the downward movement, respectively of the driver Around the driver spindle or rod D is aspiral spring G which is disposed in the socket cl bearing against the shoulder a and against the under side or end h -of the driver which acts by its tension to keep the driver at its highest position and to return it thereto if moved down and free to move. The side of the driver nearest the cylinder has a vertical-longitudinal groove or slot H which is opposite to and in line with thesocket u in-which the pin V is arranged to slide back and forth.

The lower surface of this slot extends outward to the side in a downward inclined direction, as at r shown in section in Fig. 2, making an inclined bearing surface for the pin V for operation thereof as will be hereinafter described.

Below the socket E the foot has an open space i from side to side into which project pieces J K one at each side of plates re spectively pivoted to the head at a meeting in the center, the adjacent side of each piece havinga vertical tapering groove, making as a whole a tapering socket L above socket o in the lower end, these pieces being arranged respectively to swing to and from each other within the open space 25 A spring M secured to the head by screws to hears by its forked free ends against a shoulder a on the piece K to keep it closed, and on the opposite side of the head is another spring N secured by a screw 12 which bears against the inner side of the piece J" to keep it in its closed position. The inclined passage A opens into and communicates with the side of the passage E for the driver rod just above the conical or tapering socket-L of the two swinging pieces.

A plate P is secured on the top of the block S which covers over the raceway therein, having a narrow longitudinal groove h which is over the raceway groove in the block, which plate groove is too narrow to allow of the escape of the tacks,'but open enough for the operator to see the heads as they pass along the raceway, the plate being high enough or grooved longitudinally on its under side to allow free passage of theheads of the tacks, between it and the raceway.

The portion of the raceway in the body of the machine is covered by a plate Q which has a longitudinal groove 111, over the raceway groove, which is not wide enough to allow the tacks to escape but sufficientlywide to allow the tacks to be seen as they pass along the raceway. The upper end of this plate has two lugs v on its under side which fit in between the sides 20 of the body and a horizontal plate S which projects into the chamber T of the body below the opening in the bottom of the receptacle, in which plate is an elongated opening U. The lower end of this plate is in two parts or arms V V each of which has an underlug W,they both fitting in between the sides w of the body and are arranged to press against the side by the spring of the arms, holding the plate in place. On the side of each arm V to this plate is a small projection g by which the two arms can be pressed toward each other when desirous of removing the platefrom the body.

The operation of the tacker is substantially as follows: Tacksare placed in the receptacle on top of the upper partition, and the cover placed thereon, t he tackerbei n g-held i n the left hand, which is then shaken until the tacks have passed down into and through the spimny slotted tube, the heads of the tacks pass ing dow-n'the inside of the tube with the points The head of the driver is then struck a quick hard blow whichforcesthe driver down until it is stopped by theabutmentof: its end'orshoul-= der, against the shoulder of the head; its spiral spring then acting to moveit :back to its nor- .mal position. With the driver in its upper position,- the pin. V rests-against'the part A bf the driver,which holds the cylinder in position against its spring 6': for the notch or opening g'tobe inline with the lowerendf of the race- Way groove so that in such position the tack will freely pass into the opening or'notchin the. cylinder from the raceway:as described. As. the driverjis forced down the spring e. is allowed to exercise its pressure to turn the cylinder on its axis, in the .direction of the arrow Fig 9 by the pin V passing up the incline r into the groove H in the side of the driver and; as the. cylindertso turns the tack in the notch or open-ingis carried with it, and is forced against. the point or arm'ct extending :into the horizontal-slot h." which forces the tack to move ,out of itscylindernotch,

and-the cylinder having moved so that the notchg' will be in line with the passage 'W the tack is finally moved off-the cylinder and droppedointo. this passage down which 'it passes, and th roughv the inclined passage A into the passage E above'the tapering socket L' in the two pivotedholders, and then into such tapering socket, the driverin the mean time-having risen fromthe action of its spring, outofthe way of the travel of the tack. The tack being now imposition to beidriven by the driver, the foot of the machine isthen placed on the article where-the tack. is to be used andthe driver fOI'C/QdLdOWIPfiS before, which drives the, tack into thearticle in positiontherefor, and lets the cylinder springact uponit to move the second tack forward which in the mean time has passed into the openingin the cylinder, to be forced outward by the point, into the passage down which it drops, and passes to and stops against the driver rod which has passed down by the passage in driving the tack, but as: soon as the driver rod rises and returns to its normal position, the tack drops down into the tapering socket between the two pivoted pieces and is there held as before to be driven by a blow upon the driver. Thus after the first tack has been allowed to pass down into position to be driven, by the operation ofthe parts as described, at

each blow on the driver, a tack is driven and another is moved into place to bedriven and.

so on as long as there are tacks in the machine. Just over the handle the body is cut away each side of the raceway making openings into a chamber f i-n the handle, to allow the tacks that may-not be in the raceway to drop into it out of. the Way rather than on the floor, tobe removed at pleasure by unscrewing the screw g in the handle.

The carrying cylinder or block need not be round, although it is'preferable to have. it so,

the cylindrical form being best adapted for its work" and itsparts in relation to the other part of the machine;

There is an opening in the plate P over the passage W in the block Sin which rests a knob E on the under sideof a spring arm Fise'cured by a screw G to theplate P. which can be sprung up and swung to one side leaving the opening and passage W exposed to viewso that it can be cleared of tacks if it should accidentally be clogged. The driver is inserted in place by placing the spring over its rod portion,t-hen compressingit closely against the shoulder k and inserting the spindleportion through the open spacee into itssocket d andplacing its square portion in its seat when the lower end of;the.spiral springwill pass down into its socket, and when in place, a plate HHS secured on the outside by screws J which keeps all parts in place and yet allowsfree movement of the driver up and down.

.In Fig. 3 the cover is removed from the receptacle showing the upper partition in plan View.

.The. pins 1) extending through the: upper partitionoserve to keepthe tacks separate so that they will pass more freely down through the receptacle. 1 o

. As the passage W is atone side of the-central longitudinal line of the raceway, which is in-line with the vertical axial line; of the driver rod, the inclinedpassage-A' inclines toward such central longitudinal line, as well astoward the driver rod passage E to make proper communication with: the passage. The opening m in the upper endrof the cylinder or blockT allows the cylinder tobe insertedyin its chamber from the under side of the-block S byfreely passing over the end of the arm or stripper a Having'thus described my invention, what Iclaim'is V 1.
