MECHANISM on INsEETme FASTENERS.
To all whom it my concern:
Be it known that I, HARRIE A. B'ALLARD,
' of Somerville, in the county of Middlesex which the driver-bar 15 adapted to rec1pro-- partia and State of Massachusetts, have invented certain new. and useful Improvements in Mechanism for Inserting Fasteners, of which the following is a specification.
This invention has relation to fastener inserting mechanism or implements for at tach-in theuppersto the'inner soles of fiy formed shoes.
The object of the invention is to provide certain improvements in mechanisms of the character referred to, and particularly in hand tacking tools by means of which the tacks or other fasteners may. be :fed and driven more accurately than heretofore, by which the tacks will be less likely to clog or obstruct their passageway and are more easily accessible in case of cloggingthan has hitherto been possible in previous tools, and by which the construction of. the tool may be simplified and its efficiency enhanced.
To these ends, the invention in the form illustrated in the accompanying drawings, comprises a barrel, cylinder or casing, in
cate to drive a tack through a nipple into the -work,a picker for successively presentmg tacks to theaction of the driver, and a racewa for the 'tacks which is arranged helical y about .the exterior of the barrel or cylinder and extends thereinto' to deliver tacks to the. picker. The raceway is preferably provided'with an extension projecting tangentially from the barrel or cylinder forinsertionin a loading machine.
The picker in the illustrated embodiment of the invention is adapted to reciprocate across. the. ,end of the raceway, and is spring-pressed to 'yieldingly en age and hold each tack in the path of-t e driver after it has been moved to proper position.
The picker may be-pivo ted at its upper end, and, actuated by a-pin and cam-slbt connection with thedriver-bar.
The end of the raceway communicates with a block which is apertured toreceive the driver, and-into the aperturein which the picker feeds a tack on the upstroke of the driver, and holds it yieldingly, as heretion comprises other features of construction and arrangement of parts'as illustrated Specification of Letters Patent.

Fig. 3 represents a similar section with the driver depressed. Fig. 4 illustrates the .tool partially in section on a plane at right an les to the plane on which Fig. 3 is taken. Figs. 5 and 6 are enlarged sections on the line 55 of Fig. 4 looking upward and illustrates the icker at the two extremes of its position. ig's 7 and 8 are enlarged sections of the lower portion of the tool, Fig. 7 showing the driver raised with a tack in position to be driven, and Fig. 8 illustrating the driver depressed. Fig. 9 (Sheet 1) represents a section on the line 9-9 of Fig. 1. Fig. 10 represents the block detached.

The upper endofthe barrel or casing. is closed by ahead a having a boss which may. be inserted or cylinder in the end of the barrel, and into which screws or other fastenings a are inserted.
' At'the tapering lower end of the barrel or casin is a solid portion a to which secure the shank of the nipple b. 'The driver'-' bar a is preferably angular in cross section and asses through a complemental aperture 1n they head a. On the ower end of the driver-bar is formed or secured-a driver 0 which enters an aperture a in the lowerend.
of the cylinder or .barrel, and which is adapted to pass through the ap'erture'b. n the nipple. To the upper endof the driverbar is attached the handle or head 0% The driver-bar has at its lower end laterally projectin ins orstuds 0 to whichare at tache t e lowerrends of springs. did whose bar in its elevated or raised position.
The raceway ,fer the tacks 1S, exterior. to
the barrel or casing, and extends helically therearound. The barrel is provided with two helical flanges c that at c pro ect1n'g to a slight extent beyond the outer surface of the flange c; To said flange 6 is secured a hehcal metallicstrip 0 in consequence oi which, there is iormed a groove or raceway.
e for the passage of the tacks, between it and the exterior surface of the casing or barrel. The heads of thetacks are adapted consisting of the lateral fiange e; as illustrated in Fig. 9, ,thisfiange e 4 coinciding with thefla ngee on'the casing 01' barrel. The shoulder w is formed by a projection e which, extends upwardly. from the strip '6? into enga'gementnwith the flan ere. The upper edges of the side walls 0 the extenabove the plane of said edges between the shoulder and thecasing, andg'between said edges isthe shoulder 6 which prevents the tacks from sliding rearwardly in case thebarrel is-held with the extensionpointing downwardly. The; end of the extension is adapted to be inserted in a 'suitab'le loading machine, by whichtacks will'be supplied to rd the center of the barrel, as 1.5 and 6, so as to bringthe raceway into registry"or aline= lowerpor I piacebya screw pin witha ve thedr'iver Thebloclr f is'pros 'operated -as illustrated the aperture-through the nipple, The said block has a rejecting end I f with inwardly projecting. anges f f, the upper surfaces of-which register with the up er edges of the-walls'of the raceway atits ower end, as is} clearly illustrated in Fi s. 4,"? andfS'; I These inwardly projecting d ment by 'thedrive'r. w I The picking mechanism comprises a I picker 9-, whichi-n the present instance may e n lever loosel fulcrumed upon a screw gf. inserted in a ownwardly projectin pori- Jtwn of the head a as illustrated in B ig, 4.

quate to rcceivethejshank of atack. These fingers he immediately beneath the projection f on the block f and between the inner end of said block and theglower endof the raceway. (See Figs. 5 to-8 inclusiv'e.). ZfThe mentioned figure, and it is provided with At its lower 'end, the I finger g acts as a stop to limit thepassa-ge of the tack at; the lower end of therac'eway, and this finger normally lies in the position shown in Fig. 5'; when the driver-bar is. raised. It is of; less width than the finger 9, so that the lowest tack in the raceway will normally lie-at the entrance of the pas sageway 5/ between the ends of.t he;fingers. The finger y, when the picking-lever, 18'
moved from the position inFig. 6 to the po' sition in Fig. '5.- as when the driver moves upward, engages the "lowest tack ahd Wedges it along the flanges f. of the block until it is in alinement with. the aperture f in said block. The face of the finger gf nearest the raceway holds back the ren'lain'der of the tacks in the raceway untilthe pick lever is;
moved inthe opposite directiinn io .permit th e tacks to feed one step.
t'Itwill be observed from Figs. and 6 that the fingers are less in width'than the space bet-ween'the end of the raceway and- 1 the end-of the block f. This is for-the pur- 'pose of permitting the picking lever, and v therefore the picking fingers, to move -to ward and fromthe end of the blocln The leafspring hha's on'eend bearing upon the outer face ofthe pick lever g, and
its other endresting upon the head a The 'fscrew g"; hereinbefore referred to, passes throughan aperturein 'said spring and may be screwed'in or ,out to cause;1ts--head to increase or-din1inish the pressure offthe,
sprin upon the pick'lever; It may be objserve in passing, that this screw is accessiblethrough an aperture (1' in the casing through which a screw driver may be: in-
serted.
3 From Fig. 7 it "will be observed that the- 1 inner endof the block f 'w'hich constitutes an abutment, and the confronting iface of the; finger gja're provided with. incl 'ied ,should-erst'i uponwhich the head a tack' may rest. "The tack is thus held yield L ingly between the end of the block an dthe finger g of the picker with its shank exaperture 6 ofthe' nipple.
tending into the When the driver escends, its end eh ages icking ever so as to release the tack. But the end of the driver could by engaging the head of the tack and forcing it downward, swing the picking lever bodily outward to effect the first engages the finger g and causes the release of the tack held thereby, forcing the tack downward until it is disengaged from the block and the finger. The'continued downward movement of the driver bar causes the pick lever'to be swung from the position in to feed another tack toward the aperture in the block j. The driver continues its downward movement and forces the 'tack into the work. Then, as the driver moves upe ward under the tension of the springs d d, it moves the )icking lever to the right during the middie portion of its upward move- 20 -ment, and as the end'of the driver is raised to a point above the picking fingers, the spring it forces the lower end of the lever toward the block, so that the tack is pushed against the abutment where it is heldyieldingly as previously described, the tacks in the raceway, in the meantime, sliding down so that the lower tack rests against the outer face of the finger-g in alinement with the passageway between the beveled endsof the fingers g 9*. Thus at all times when the driver is raised, atack is held in position to be forced by the driver-into the work.
So far as I am aware, I am the first to have provided a hand tacking tool of the 35 character herein described, in which the raceway extends helically around the exterior of the barrel or casing. One ,of the advantages of the construction isthat the heads of the tacks are always visible between the upper edge of the strip 6 and the flange or cover a, so that in casethey become clogged or stuck, the 'point at which they become clogged may be observed at once, and they may be forced into the raceway and be.
brought into proper overlapping relation.
Y Another feature of the invention which I regardTasnovel, is the yielding picker by which the tacks are-advanced successively into the driving position -and by which they are held yieldingly in said position to be engaged by the driver. While in this embodiment'of the invent-ion, I have. illustrated the pickers as mounted upon a-pivoted lever, nevertheless, I am aware that this and scope of the i nvention.- This feature of the invention, as well as others, may be utilized in other forms of fastener driving machines. 1
There are other features of the inventionwhich I regard as important, but to which I neednot refer in detail as their advantages will be' apparent to those skilled in the art 5 to which this inventionrelates.
