.TQQZZ .whom it may concern:

Beit knoivn that RONALD F. McFnnLY, a citizen of the United States, residing at Beverly, in the county of Essex and State of llflassachusetts,.have invented certain lm- -provements ln Tacking Mechanisms, of

which the following description, in connec' tion with the accompanying drawings, is a specication, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and particularly to nailing or tasking apparatus `used in such machines.

The invention is shown for exemplicationI as embodied in a pullingover machine of the type shown in the prior ida-tent No. 663,777 granted on my application December 1l, 190G, but protection is sought for all uses for which this invention is adapted.

The general object of this invention is to provide for variations in the positions at which tacksshall be inserted, and it may be also in the number of tacks driven.

A very important feature of the invention is found in the provision of means for changing the lateral position in which the toe tack is inserted. lit is found in the use of this pulling-over machine, and similar conditions might be met in other machines, that right and left shoes made on crooked lasts can be moet satisfactorily secured at in accordance with the preferred embodi- 'ment of this invention the tacker and Wiper are adjusted together, and also the toe gripper of the machine is adjusted in company therewith.

ln accordance with another feature of this invention provision is made for adjustment to vary'the distribution of the tacks to the toe and side tackers. This feature of the invention solves the problem presented in factories making styles of shoes which require the upper to he secured at different points. `For example, shoes hasni: short vamps re.-

quire to be pulled and fastened by a tack Close to the toe at each side of the last. When these shoes are made on lasts which latented Apr. 13, 1915.

have high or prominent toes and are relatively thin between the toe and the instep the shoe requires to be pulled and fastened by a tack driven Well back along the ball of the. last. To meet these varying conditions, each side tacking mechanism of the machine is equip ed, in accordance with a preferred form o this invention, with the maximum number of drivers, tack holders and conductors which Will at any time be required and the tack supplying and distributing mechanism is constructed and arranged to deliver the Whole number of tacks or a selected series of tacks. For this purpose novel means, Which may be independent of the separating mechanism, is provided for stopping the deliveryof tacks from selected raceway grooves whereby a varying predetermined number and arrangementof tacks is delivered into position to be driven by the selected drivers.v These and other features of this invention, including` certain details of construction and more important combinations of parts, will appear in connection` with the following description of the illustratedmachine and then will he pointed out in the claims. f

Figure 1 is a side elevation of a pullingover machine equipped with the present improvements; Fig. 2 is a perspective view of the toe tack driving mechanism; Fig. 3 is a perspective Viewr of the tack distributing mechanism; Figs. 4, 5 and 6 are front views of the tack controlling mechanism in different positions of adjustment With accompanying diagrams to show the arrangement of tacks in the shoe following from each adjustment; Fig, 7 is a side elevation of the adj listing devices.

l The machine comprises the head 2 which is supported on a post and has bearings for a shaft 4 from which is reciprocated a rack 5 that drives a tack lifter in the hopper 6. From the lifter the tacks gather in rafceway grooves, Fig. 3, `which are inclined. dovvnwardly toward the toothed separating slide l() which, by reciprocatory movement across the ends of the raceivays, takes a tack from each groove that is open and delivers i t to the appropriate tack tube 12 by Whichit is conducted to its tack pocket in the side or vthe purpose of this description may be con sidered as a single member with tack grooves therein, is cut away at its lower end above the separator slide 10 and its cooperating parts to receive plates 22, 23 that have passageways 24 cut through them in position for alinement, respectively, with. the first and second and the siitth and seventh race-l way grooves, The upper portions of the opposed lateral walls forming the sides 0f the passageways 24 are extended inwardly.' asv fingers 24 located below the tack head supporting surfaces of the raceway block in position to be projected transversely across the tack' grooves in the path of the tack stems's may be seen from the illustration in' Figs. 4, 5 and 6. This embodiment of the Ainvention therefore, presents a tack controller'22, 24a, 24a for the first and second tack grooves which is located on the left side of the first groove and on the right hand side of the second groove, and a similarly arranged controller 23, 24a, 24 for the sixth and seventh grooves, the lower wall of the passageway being located below .the stems of the tacks in the grooves where it extends across the grooves and the intervening structure of the block 20. The plates have overlapping ends both of which are operatively connected with an adjuster 25 which can be rotated by a screw threaded block that is adapted .to be turned by the tool 26 through an angle and in directions appropriate to separate the plates farther (Fig. 6) from their normal relatiornFig. 4,01' to draw them closer together, Fig. 5. The passageways 24 are so proportioned and located relatively to the raceway grooves that when the plates are in the central position, Fig.' 4, all the raceway grooves arekopen and tacks will be sej'varated and fed for insertion as indicated in the diagram that is below Fig, 4. When the plates 22, 23 are 'drawn closer together by the manipulation fof the adjuster as represented in Fig. 5 the plates close the first and seventh raceway grooves and permit the delivery of vonly five tacks and these tacks are the ones which go into tubes associated with drivers that insert them in the relation shown in the Fig. 5 diagram. lVhen the adjuster is shifted to the position shown in Fig. G the plates 22. are separated and close the second and sixth raceway grooves thereby cutting out the intermediate tack as inthe Fig. 6 diagram. By this means different predetermined numbers and arrangements of tacks can be secured without changing the running parts of the machine.

To prevent liability of unauthorized tamperingA with the adj uster it is located under the cover plate 21 which has to be removed jby manipulation of the thumb and finger studs 19 in order to uncover the hole through which the adjusting tool 26 is to be inserted. This tool is to be in the custody of the foreman whose directions as to the number and arrangements of the tacks is to be followed.

similar arrangement for delivering one or y :mother of a plurality of-tacks to a toe tacker having two or more drivers might be employed but to save space and duplication of parts and to obtainother advantages the toe tacker is instead madelaterally adjustable to insert a tack at or on either side of the median line of the machine and .preferably in any one of many locations whereby it is adapted for operation on right and left shoes of more or less crookedness. To this end the toe tacker arm 35 which is hung upon the frame at 36 for inward and outward swinging is pivoted at 38 for lateral swinging movement. It is also transversely slotted at 40 to receive a cross bar 42 connecting the wide spread'ends of the forward fork 888 'of the mechanism by which it is actuated inwardly to tacking 'position and outwardly to position for clearance.. This mechanism in other respects than the pres'- ence of this bar and the width of this fork' may be the same as shown in Fig. 39 of my prior patent. The guideway in the machine ,head 2 throughwhicl. the arm moves is also made wider than the arm and it is overioo laid by a plate 45 in which the arm fits as. 4 to wid h but can move freely forwardly vand backws rdly. This plate has a laterallyl ex'- tendedV toothed arm 4G thatis engaged bya segment rack 4S connected with ay hand lever 50 in which a spring pin is held to rengage a fixed ratchetplate 52 for locking the lever with the plate 45 andthe toe 'tacker arm in laterally adjusted position. The conductor tube' l2'for the fourth. tack is secured to the tacker arm for adjustment with it, said tube .ieing loosely connected to the'raceway block to permit this movement.' The toe gripper may haveits bar G0 guided in the plate 45',

as shown in Fig. 2, for lateral movementl with the toetacker and the toe Wiper 62,

which lays the'upper upon the shoeinnersole l laid in the proper position -under;the. tack from the laterally adjusted tacker.

In the use of the machine, the toe grippersseize' and pull the upper as usual,

and side s the pairs of jaws of the `double side.gripz-,fiil

' incense ing edect is not desired, as may be the case in some shoes, the Fig. 'adjustment is made to cut out the first andseventh tacks. It

on the other'hand the intermediate tacks are not required, the Fig. 6 adjustment vvill discontinue the delivery of the second and sixth tacks.

because all the pulling-over tacks have to be removed from all Welt shoes and they are taken out from McKay shoes to a large extent for the lasting operation. The toe tacker is adjusted for the shape or'the last that is in the machine and with it is also esv ' gang means for inserting a plurality of tacks into each` side of the shoe, and means which adjuste'dvthe toe Wiper andthe toe gripper. This. adjustment can be made at any time, either before 'the machine is started, or initially, or supplementally Whilelvlthe gripper holds the upper.
