5 monwealth of Massachusetts, have invented certain Improvements in Machines 'for In: serting Fastenings, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indi a a n eating hke parts in the several figures.

This invention relates to machines for insert ng fastemngsand the'partlcular embodifnent thereof herein selected for illust-ration comprises tack supplying and driving mechanism for a lasting andnailing machine. This mechanism includes a hopper,

a racewa a tack separating mechanism, and a ho der to rece ve these arated ta'ckand present it in position to be driven.

The, invention has forits general objects to provide for a more certain 'and accurate supplviand delivery of the fastenings than has heretofore been secured, to provide means by which the fastenings can be inserted in certain articular positions in the manufacture of s oes, to render the supplying mocha fa ng e durable and to make provisio y gaining access to ceri t lons' oi the mechanism that require frequent cleaning- 1 a As hereinshown the ra wayis inclined ,downwardly fiomthe', op er to the tackseparating mechanism cause the tacks to 85 travel alonE-it by gravity: The tacks are supported;

their heads in .the' inclined raceway an therefore, usually stand with their stems hanging obliquely downwardly and backwardly.

A feature Qt this. IILVGIIHOH consists in providing meaps for presenting the tacks to the tack-separating mechanism with the stem;

of the tack to'beseparated and the stem of the tack next'zabovedt'diverging one from or blade may more -readily as between the two tacks.

To this end the invention contemplates the revision of raceway-having at its dolive end a raceway section or separating 5 table comprising tack-supporting surfaces at an angle to the tack-sup ortingsu'rfaces of the adjacent section, so t at the stems of the tacks onthe respective "sections'will 'diverge.

As herein shown, a separating table is provided having horizontal head-supporting surfaces upon which the tacks pass from the inclined raceway and which cause the stemh of the tacks to assume a vertical position by gg" gravitation. Preferably the separating table is arranged with relation to the tack Separating mechanism so that the separator blade passes between the lowermost tack on'the inclined portion of the raceway and the ad jaccnt tack on the'horizontal guide. The raceway preferably contains one or more grooves from which the tacks are delivered to the lower section or the tack-separating table, when one of the grooves is in suitable relation to the receiving groove in the table. This receiving groove in the tablemay be in alinernen't with the raceway groove or it may be inclined relatively thereto. In .the

former case I obtainthe best results by lmakiu'g the separator blade with a separating face inclined at an angle of about 30 -toward its direction of longitudinal movement. This arrangement'gives, however, a long slender separating blade which is less durable than a shorter and blunter blade}.

would be. I may, therefore, inclinetthe re-f ceivinggroove of thetable with relation to the delivering groove of the racewa as, for example, at about30 and this a lows the face of the blade to be inclined at an angle of aboutGO .to the direction of its longitudinal movement and still have with reference to the receiving groove .the same. angular relation so that-thetack-is urged along that groove at the same rate as by the sharper blade. to make andwill wear longer than the more slender one.

In the of the machine misshapen tacks and forei subst ariccssometimes get into This blunter blade is easier;

the tack-separating mechanismand for this and other reasons it is quite frequently neces sary. for the operator to gain access to the; covered arts of the mechanism. I"have,

in acc'ort ance withone feature of the invention, provided for hqlding this mechanism in assembled relation u on the raceway by l novel means which wi l rmit the separatj-' ing mechanism 'to be qulckly attached and] disconnected without th'e useotan tools or the removal of fastening devices.

shown,

thisholdingmeans comprises a supporting mama between whicll and the raceway cat lea rier the separating mechanism has a sliding fit combined with devic es for automatically positioning said mechanism when it is moved approximately tocorrect position and de- 6 vices for clamping said mechanism in place.

The tacks which are forced along the receiving groove by the separator blade ultimately fail; into a tack holder which is movable from receiving position outwardly into 10 tack-driving position over'the work. a In making turn shoes havin tacked heel seats the upper is fastened totlie eel seat piece after the shoe is turned. In order to do this the heel end of the sole is bent upwardly, the 1!? up i wiped inwardly under it, and the ta are driven in a line from the end-of the seam connecting the sole and upper at the shankon one side of, the shoe to the beginning of the seam at the shank on the other 0 side of the shoe. In order to drive the tacks 'as'near as possible to the end of the seam it is, necessary that the tack block should be narrow to enable it 'to present the tack close to the upturned sole. A feature of. this invention consists in a 'novel construction of tack block which is particularly adapted for tacking'in such positions as that closely adjacent to the ends of the seam and is alstijwell adapted for tacking the other portions 'of the shoe. In the embodiment herein shown of this featureof the invention the tack block comprises a narrow carrier having a longitudinal rece'ss in.

, whioh tack fingers. are mounted one in ad- Vance of the other and arran ed for movement in, opposite directions engthwise of the carrier for permitting the tacks to be exelled between them. A single endwise-acting spring is employed for pressing the two 40 tack fingers together,--connections being provided for this purpose between one end of the spring'and one opposite end of the spring and the opposed finger. By ,this arrangement and construction of the tack fingers and their spring a narrow block can be obtained by which a Y tack can be driven very close to the end of the inseam. For further adapting this tack holder to position a tack close to the end of theiiiseam the holder is made ta ering in transverse section, the greater wi th being y at the bottom where the holder can fit under the upwardly bent heel end portion of the '1 sole. Preferably also the tack holder is pro-.

vided on its lower side with a wiper and'this 'per has downwardly and outwardly inl 'ned; edges. The W1 er thus presents a i rubbing face wider: than the tack derandadapted to act upon the upper to o' fofrce it into lasted ositioii in the angle between the sole and t h 'up'to' "the end of the inseam. The wiper has a tack opening and is grooved lengthwise to receive and permit movement of the tack fingers. 'iTherac'eway extends into the-hopper accidental removal.

or and between the e last bottom and. close to receive the tacks and where it passes through the hopper means is provided for dislodging tacks that are incorrectly placed on the raceway and for agitating the line of tacks in the hopper-contained section of the 7 raceway. This means comprises a clearer which is oscillated lengthwise of the raceway and is longitudinally extensible so that it presses yieldingly upon the upper edge of the raceway and pushes back the line of tacks as it is moved up the raceway. A block is provided which forms a close fitting cover under which only those tacksare allowed-to pass which are properly placed and the block has a guiding surface over which 30 the clearer slides as it approaches the level of the raceway to dislodge the tacks that are not correctly placed. This block is preferably so mounted-that it can be readily removed to allow the raceway to becleared. 5 The movement of the clearer over the guide tends to tilt it and causes it to wear the adjacent face of the hopper, which is of softer metal, until the block becomes-loose so that misplaced tacks sometimes pass under it and clog the raceway. The present invention contemplates the provision of a yielding device for the guide block so aras to"resist the tendency of the clearer to tilt the guide block. By the use of this device wear of the block and hopper is decreased and liability of misplaced tacks clogging the raceway is reduced. The lockmg device also serves to hold the block from These and other features of the invention, including certain combinations of parts and details of construction, will be explained more fully in the following description, and in connection with theaccompanying drawings, and pointed-out in the claims.

Fig. 5 shows the re movable end block. Fig. 6 is a bottom elevation of the tack holder. Fig. 7 is a side view; Fig. 8 is a transverse section. Figs. 9,10, 11, and 12 show. modifications.

The hopper 100, which is supported on the frame of the machine,.contains rotarytack lifting devices that are driven through the toothed wheel 191 from the main shaft of the machine. The raceway 102 extends into the hopper and tacks are supplied by the lift ing devices in large numbers to this inclosed portion of the raceway.- Those which fall upon the raceway in such position that they become suspended bytheir heads upon the supporting. faces of the racewayfslide by gravity to and along the outer portion of the raceway to the tack-separating mechanism. At the point where the racewaypasses through the wall of the hopper'it is 130 covered by ablock 104, wliibh has in its lowerface a groove for the heads of the tacks and permits only those tacks which are properly arranged in alingment to pass thereunder. At the inner side of this block the raceway 'and the lower side of the raceway holein'the hopper and is normally held from sliding out of place by the removable cover 110 which fitsover the outer portion of the raceway. It frequentl ha pens, however, in the use of themac ine t at it is necessary to remoyethis cover in order to give access to the raceway, and when this is done the block .104 is liable to be'forced out of position-by the clearer. To insure against this-occurrence a device 112 is provided for Holdin the block 104 against displacement. This holding device is shown as a spring-pressed plunger mounted in a fixed portionfof the ho per and having an operat lng handle engaging a cam face 105 which is formed to 'retain the holder in an elevated position when the holder is lifted and.turned by the operating handle. The holder is arranged to bear yieldingly upon the upper face of the block near'itsouter end and thereby serves another purpose in resisting the tendency of the cleare .s inftheir intermittent movement tofro c the block and cause it to-wear the relat vely soft cast iron of'the hop er which wpuld allow, the block to become ooseand unsatisfactory in use.

The main portion of the raceway is inclined as shown, to cause tacks suspended by their heads on its upper surfaceto slide.

' down by gravity. At the delivery end of the raceway is arranged tack-separating mechanism comprising, as shown in Fig.3, a gate 120and a reciprocatory blade 124; for separating the "lowermost tack in the race- "way from those above it. The ortion' below as a removal;

the'sep'arating blade is conveniently formed 121 of the end block form a supporting table upon which said lowermost tack is sustained by its head and these faces are arranged at an angle to the head-supporting"surfaces 122 of the main portion of the raceway so that the'stem of the tack to be separated will han at an angle or diverge from the stem of t ei-next t-ack above it-and, therefore, provide wider space for the passage of the end block. The upper faces separating gate than would be provided by tack stems hanging parallel to each other. Preferably the faces 121 will extend horizontally, but any inclination relative to the raceway that would cause the stems to diverge as described would be advantageous. After the separator gate passes between the tacks the separated tack is forced by the slotted plate 124 into a position where -it may fall through the vertical delivery passage 119 into. the reciprocating tack holder 125 from which it is inserted into the stock by a driver 126 actuated by a usual spring not shown. It will be observed that the tack groove in the end block is in line with the raceway. groove in Fig. 3 and the separator blade 124; has asharp slender finger formed by the inclined slot in its inner edge, The best. results are obtained when the inclination of this slot is about 60 to the tack groove in the end block, or about 30 to'the direction of the reciprocating movement of the blade. The separating fingerjs subjected to constant wear and I haveshown in Fig. 4 a modified arrangement in which the tack groove 121in the end block below the a separator blade is formed at an angle of about 30 to the'groove in the racewayand the transferring edge of the blade, having the notch 117 to permit the passage of the head of the tack, is formed at an angle of about 60 to the direction of its movement. This still gives an'a'ngle of about the same size (60 degrees) between the groove and the slotin the blade 50 that the advance of the tack along the groove is the same as before, but the separating finger is blunter and therefore more substantial and durable. The separating table and the end block 123 of the raceway form, with the errd face of the raceway sect-ion 102, a guideway for the separator blade which is actuated endwise by suitable connections with the tack .holder 125.

The end block and its associated parts are, as shown in Fig. 5, removably held in -place by a supporting plate 127 provided with holding meii'ib'ers .129 having tongue and groove connections with tl1e .end.-block and a locating recess to receive-the spring: pressed ,locatmg pin 131 having a beveled lower end. The supporting plate 127 is itself clamped to the raceway carrier by thumb bolts lfid'yi'hich extend through open ended slots in the plate and permit the plate itself to be removed when they are lcoseiied.

It is not necessary, however, to remove the late in order to remove the end block. en theiclaufkping thumb nuts are loosened they havesu cient play in their slots to permit the removalof the block without entirely removing the plate. When the block is replaced it is simply slid endwise to the left (Fig. 5) behind the holding members 129 until the pin 131 snaps into the hole inthe plate whereupon the block and its su porting plate arepressed inward and tie thumb nuts tightened to clamp the block in position against the raceway support.

' The tack holder 125, which'is actuated by suitable mechanism forwardly from receiving position directly under the separating mechanism into position over the work into which the tack is to be driven, is shown more in dotail in 6, -7, and 8. The holder has laiackand driver passa e 182 in which a tack may be supported y the b fingers 184, pivoted at 185 in the fore part of a longitudinal groove 188. The fingers 1 are arranged one in advance of theother, as shown, to allow .the tack holder to be made'narrow. -This-is particularly desirable-in machines used-for lasting the heel seats of turn shoes, for in this work, in 29 which the tackholder is advanced over the shoe bottom into sition for the tack therein to be driven or securing the upper in its overworked position,.,it is necessary-that the tack holder advance under the upturned 2 .heel end .of the sole and drive tacks as close as possible to the angle between the sole and the end offthe inseam. The fingers 184 are yieldingly held ressed together to support the tac ,but alihw the driver to force th e tack therebetw een, by means which includes.

.a loop 186 seated in a groove in the front finger and extending" rearwardly Wltll ts side arms embracing the sides of the fingers. The -rear ends of the'side arms are inturned to form hooks that extend throughthe walls of a spring case and terminate between two collars on a plunger 192. .The plunger is engaged by a spring 190 seated 'inthe case and the front end of the lunger rests in a '40 recess in the back side of t e rear finger 18.

-. With this arrangement theone spring 190 acting in one 'directionthrough the loop 186 and in the reverse direction through the plunger 192 holds the two fingers yie din 1y i 4. toward each other with equal forces. he

ends of the loop stand in the space 194 betweenthe caseiand-fithe -'reduced portion 192- of the plunger and by limitingv the forward movement of theplunger centerthe two tack 9' fingers with relation to the driver passage 182.; Not only is the tack holder'made narrow by arranging the tack fingers and their associated parts as. described, at the slde faces of the holderare inclin f upwardly and inwardly toward each other, as shown 8, to conform -them tothe-position' of the upwardly bent face of the sole and allow a tack to be driven as7close*?as Poss1-- 'ble to the" "end of th inseam. Preferably V and as shown, the tack holder carrieson its;

lowerside-a' wiper 196 which is the 'device thatforces the upper into position to be secured, or assists in doing so. The edges of this w perlare inclined like the sides of-the raceway t holder soth'at the wiper has a broad'lowr,

ranged one in advance of the other lengthwise of the tack holder and are held in tacksupporting position by suitable coiled;

springs. In the construction shown in Fig. 10 thetack fingers are arranged tgansversely of the block and are held in posit] on by leaf- 8o springs1 204. In both Figs. 10 and 1242119.

tack gers are arranged .to slide outwardly and upwardly with relation to the driver passage to permit the'tack to be driven. In Fig. 11 the tack fingers are shown as spring 5 pressed plungers 205 arranged to s li e downwardly and outwardly 1n guideways extending obliquely with relation to the driver passage-182. In Fig. 9 the fingers or plungers 205 slide horizontally outwardly go as the driver forces the tack downwardly. In the use of the machine the tack lifting devices deposit tacks upon the portion of the tacks that enter the raceway groove properly. 5 slide under the block 104 andthose that gather at the entrance are dislodged by the clearer 106,, the shaft of which receives an intermittent rocking motion from the wheel 7 101. The clearerjsweeps forth=andback10o over the block, which is securelyhel'd-in place by the plunger -112, even when the' raceway cover is removed and'if it .becomesj necessary to gain access to the portion of)- the raceway groovejthatjs covered by they block 104 the handle 6f the plunger .is'
