Application filed September 9, 1905. Serial No. 277,653.

To all whom it may concern:

Be it known that I, J on B. I'IADAWAY, a citizen of the Uhited States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Tack- Pulling Machines; and I do hereby. declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to tack pulling machines and more particularly to tack pulling machines provided with tools or devices adapted to engage the projecting last:

ing tacks of it lasted shoe and remove the tacks from the shoe.

The objects of the present invention are to provide a tack pulling machine adapted for operation upon it lasted shoe, having improved means for guiding and supporting the shoe during the operation of the tack pulling devices so that any liability of injury to the upper of the shoe is avoided, and the tacks are properly positioned for engagement by the tack pulling device or devices.

Other objects of the invention are to provide a simple and efficient tack pulling mech anism which will act with certainty to engage the projecting lasting tacks and remove them from the shoe, to rovide simple and etlicient means where y the tacks after being removed from the shoe are ejected from the tack pulling device or devices, to provide means whereby tacks which may be thrown from the tack pulling devices while being removed from the shoe are directed away from the tack pulling de vices, to provide means by which a tack which is not in position to he engaged rop erly by the tack pulling devices is de ected so as to be moved into proper position, or moved to a position in which it will not be engaged by the tack pulling devices, and in general to improve and simplify the organization, construction and mode of operation of the various parts of tack pulling machines.

With these objects in view a feature of the present invention contemplates the provisionin a tack pulling machine of means for engaging the upper on opposite sides of a projecting lasting tack, constructed and artacks.

ranged'to guide the tack into position to be acted upon by the tack pulling device or devices, these means being preferably work supports arranged to form a throat the sides of which engage a projecting lasting tack and guide the tack into position as the shoe is presented to the machine. One of these work supports is preferably rigidly or unyieldingly mounted and is arranged to bear against the shoe upper outside of the line of lasting tacks, while the other work sup port is arranged to yield and constitutes a yielding downhold arranged to bear against the shoe upper inside of the line of lasting tacks. \Vith this construction and arrangement of the work supports the support which bears against the upper inside of the line of tacks is allowed to yield when the shoe is forced against the unyielding work support, and the shoe can be manipulated to cause the unyielding work support to force the upper outside of the line of tacks firmly against. the sole, in order to enable the tack pulling device to engage a tack which has been driven deeply into the last.

The improved tack pulling mechanism of the present invention comprises a tackpulling jaw which is actuated to engage a projecting lasting tack and removp the tack from the shoe, and a stationary jaw arranged to engage the tack and support it against the thrust of the tack pulling jaw, and in the specific embodiment of the invention hereinafter described the statiopary jaw also forms the unyielding work support above referred to, which bears against the shoe upper outside of the line of lasting The stationary jaw engages the opposite side of the tack from the tack pulling jaw and supports the tack when the tack pulling jaw moves into engagement there with. In order to hold the tack in engagement with the tack pulling jaw while the tack is being removed from the shoe, the stationary jaw is preferably extended paral lel with the path of movement of the tack pulling jaw and thus the complete removal of the tack from the shoe is insured. The surface of the jaw which extends parallel with the path of movement of the tack pull.- ing jaw forms a guide which holds the tack in engagement with the tack pulling jaw and any guide which acts to hold the tack in the jaw during its tack pulling movement is considered to be the equivalent of this guiding surface.

In accordance with a featureor" the pres ent invention an ejecting movement is im parted to the tack pullin tool after the tack has been removed from t e shoe, this movement of the tool being so timed with rela ti'on to the operation'of thetool, and being 111 such a direction as to forcibly eject 'the tack from the tool. While this feature of the invention, broadly considered, contemplates imparting any suitable movement to the tool which'will forcibly eject the tack, in the preferred form of the invention an ab rupt lateral movement is imparted to the tool shortlyafter thepoint of'the tack has been moved out of engagement with the shoe upper. 4

. It is desirable in tack pulling machines that the tack pulling tool be operated at a high rate of speed. When so operated, however, a tack is occasionally thrown from the tool during its tack pulling movement, and

in order that tacks so thrown from the tool "may be directed away fromthe tool, a feature of the-present invention contemplates guard plate arrangedto and deflect them away manner, but in order thatthe plate may be' located as close as possible to the toolit is.

. preferably mounted to I11 illustrated embodiment of the invention 7 invention hereinafter hereinafter described, however, a stationary ejector is provided against which the tack; is brought by the ejecting movement of the;

tool, and which acts to tilt the tack and aidf in dislodging it from the tool. The provi- 'sion inn tack pulling machine of a station-; aryej ectingdevice arranged to engage a tack.

during the movement of the tackapulling tool and remove the tack from the tool is jbelieved to be new, and is considered to con-.

stitute a feature of the present invention. In the specific embodiment of the invention the stationary ejecting device is formed. by

the upper edge of the stationary jaw and the tack pulling jaw in its ejecting movement moves across the upper edge of the sta- -This. guard plate may be ove with the tack pulling tool; v The-ejecting'movement which. is imparted to the tack pulling tool may be relied. upon. alone to eject the tack from the tool. In the;

pulling jaw is houses In the operation oii tack pulling jaws as heretofore constructed it has been found that a tack is occasionally engaged by the extreme end of the work-engaging face of the jaw and is thrown sidewise from the jaw as it is removed. The provision of a consists in certain. devices, combinations and arrangements of parts hereinafter. described and: claimed,' the advantages of which will be obvious to those skilled in the art, from the following description.

The various features of the, present invention will be clearlyunderstood from an inspection of the accompanying drawings, in 'Which-- Figure 1 is a View in. side elevation of a tack pulling machine embodying the same in their preferred form; Fig. 2 is a View in front elevation of the machine with a portion otthe framev broken away to show the construction of the'delivery chute; Fig. 3 is a detail sectional view illustrating the (IMP struction and arrangement of the downhold, the stationary jaw, the tack pulling jaw, the guard plate and the delivery chute; Fig. 4' is a -detail view of the tack pullin jaw and the stationary jaw, indicating 1n dotted lines the path of movement of the' tack pullin'g jaw; Fig. 5 is a plan view of the tack pulling jaw; and Fig. 6 is a plan view of the downhold and stationary jaw.

The stationary jaw is indicated at 1 and is rigidly secured to a projecting portion 2 of the machine frame. p

The yielding downhold is indicated at 3 as consisting of a thin metal plate secured so as to becapable of vertical adjustment to an arm at rigidly secured to or forming a part of a projection 5 from the machine frame above the projection 2.

The adjacent edges of the jaw 1 and downhold 3 are arranged at. an angle to each other as indicated in Fig. 6 to form a throat G, the edges of which engage the sides of a lasting tack when a shoe is presented to the machine and guide the tack into position to be'engaged by the tack pulling jaw. The shoe upper is engaged by the stationary jaw and downhold upon opposite sides of the lasting tack, and the jaw and downhold thus constitute work supports for guiding the shoe and holding it in position during. the

operation of removing the lasting tacks. As will be apparent from aninspection of Fig. (3, the shoe upper s also engaged by the downhold 3 directly in the line of tacks, the

downhold 3 being provided with a portion at the end of the throat 6 which extends across the line of lasting tacks and serves to prevent the upper from bulging up into the throat between the stationary jaw and the downhold. The shoe is presented to the machine with the line of lastin tacks extending parallel with the tac. -en aging edge of the stationary jaw so that t e sta tionary jaw'bears upon the upper outside of the line of lasting tacks and the downhold bears upon the upper inside of the lasting tacks, the upper on both sides of the line of tacks being held out of the path of movement of the tack pulling jaw,- and each tack being guided into position to be engaged by the jaw as the shoe is fed by the operator. The downhold 8 which bears against the upper inside of the line of tacks is capable of yielding vertically so that the shoe can be forced against the stationary jaw 1 with sufficient pressure to bring the edge of the jaw beneath the head of a lasting tack which has been driven Inore deeply than usual into the last.

The tack pulling aw is indicated at 7 and is provided with a working face or edge 8 adapted to engage a projecting lasting tack. The tool is actuated to cause its working 'face to move in the path indicated in dotted lines in Fig. 4, the tool moving down- I wardly and inwardly toward the lower edge of the stationary jaw to engage the lasting tack below the head of the tack, and then r moving upwardly to withdraw the tack from the shoe. As the tool moves into engagement with the tack the tack is supported against the thrust of the tool by the lower edge of the stationary jaw, and while the tack is being pulled from the shoe it is held in engagement with the working face of the tack pulling jaw by the surface 9 of the stationary jaw, whichextends parallel with the movement of the working face of the tack pulling jaw and forms a stationary guide for the tack. After the working face of the tack pulling jaw has moved above the upper edge of the stationary jaw, it is given an abrupt lateral movement over the upper edge of the jaw, which lateral movement forcibly ejects the tack from the tack pulling jaw. The movement of the tack pulling jaw over the upper edge of the stationary jaw brings the tack into engagement with the edge of the stationary aw and the tack is thereby tilted and dislodged from the working face of the tack pulling j aw, the ejecting action of the upper edge of .the stationary jaw .in connection with the lateral ejecting movement of the tack pulling jaw causing the tack to be ejected with absolute certainty.

The projection 2 from theframe of the machine is hollow, being open at its upper end and provided at its lower end. with a discharge opening 10 so that a chute is formed to receive the lasting tacks extending into close proximity to the stationary jaw and tack pulling jaw. The tacks are ejected directly from the tack pulling jaw into the chute and are delivered from the chute into a receptacle placed to receive them.

The tack pulling jaw is operated at a high rate of speed, and in order to direct tacks, which may be thrown from the tack pulling jaw during its tack pulling movement, away from the jaw and into the chute, a guard plate 11 is provided which, as shown, extends across the path of movement of the Working face of the jaw and projects into the chute. The tack pulling jaw is secured so as to be capable of vertical adjustment upon the lower end of a lever 12, and in order that the guard plate 11 may be as close as possible to the working face of the tack pulling jaw at all times, it is also secured to the lower end of the lever so as to move with the tack pulling jaw.

The deflector upon the tack pulling jaw is indicated at 13 and, as clearly illustrated in Figs. 1 and 5, consists of a rib at one end of the working face 01 the jaw, the rib extending above the working face of the jaw a sufficient distance to engage the head of the tack, and being provided with bevels at its end to cause a tack, the head of which is engaged by the rib, to be deflected into or out side of the path of movement of the jaw.

To impart the desired movements to the working face of the tack pulling jaw, reciprocating and oscillating movements are imparted to the lever 12. The lever is -piv-' otally mounted upon a slide Ll mounted to ireciprocate in vertical guidcways in the pro ection 5 of the machine frame, and is connected at its upper end by a link 15 to a lever 16 pivotally mounted upon the frame of the machine and provided with a cam roll engaging the groove of a cam 17 secured upon the driving shaft 18 of the machine. The driving shaft 18 is rotated constantly during the operation of the machine by means of a belt passing over the driving pulley 19 and is provided at its forward end with an eccentric surrounded by an eccentric strap 20 connected to the slide 14. The eccentric and strap impart reciprocating movements to the slide M and the cam 17 through the lever 16 and link 15 impart oscillating movements to the lever 12, and these oscillating and reciprocating movements are so timed with relation to each other that the working face of the tool is caused to move in the path indicated by the dotted lines in F ig. 4.
