MACHINE :FOR SETTING HEEL AND SOLE rRo'rECToRS.

WIN TER, a

citizen of the United States, residing at' Lawrence, in the county of Essex, State of Massachusetts, have in vented a certain new and useful Improvement in Machines for Setting Heel and Sole Protectors, of which the following is a specification, reference being had therein to the accompanying drawings. Y The invention relates to machines for driving or setting metallic reinforces or protectors into the heels and soles of boots andl shoes for the purpose of retarding and equalizing the Wear thereof.

More especially, the invention has relation to the devices which are employed in such machines for presenting and positioning the protectors or reinforces preliminary to the driving thereof, and assuring that the protectors orreinforces shall be driven in the proper position into the stock which re-V ceives the same.

The invention consists in the features which I will now proceed to describe with the aid of the accompanying drawings, in which latter I have illustrated the best forms in which the invention has thus far been embodied.

The characteristic features of the invention will be particularly pointed out and distinctly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a view in vertical section of portion of a protectorsettingmachine having one embodiment of the invention applied thereto, only so much of the machine being shown as is necessary in order to properly disclose the nature and relations of the invention. Fig. 2 shows in plan the protector-transferring, holding and guiding devices pertaining to the said embodiment, the slides being in their retracted and open position represented in Fig. 1.

Fig. 3 is a view in vertical section on' the plane indicated by the dotted line 3-3, Fig.

2, looking in the direction indicatedby the arrows adjacent the ends of such line. Fig. 4 is a view similar to Fig. 2 showing the slides closed together and advanced. Fig. 5 is an edg'eview of the Said devices. Fig. 6 is a view in vertical section on the plane Specication of Letters Patent.

,are intended to be driven with the aid of the devices embodying the invention.

Extensive use is made in practice of reinforces or protectors which are formed of bent strips of metal, these being applied by being driven edgewise into the leather of the top-lift of a heel, or that of a sole,.until the edges thereof remaining visible are flush with the outer surface of the top-lift or sole, or substantially so. 1, Fig. 15 designates a forni of reinforce or protector of this general class, it being substantially of horseshoe shape, with one edge 2 thereof formed sufficiently thin to enable the Same to penetrate readily the leather into which the reinforce or protector is driven, while the other edge 3 thereof is somewhat thicker. Edge 2 may be termed the entering edge of the device, while edge 3, which is exposed at the face of the Work into which the reinforce or protector is driven, and primarily receives the wear, may be vtermed the wear-receiving Hereafter the term protector will be It will be understood that while I have vshown only one well known form of protector, the invention is equally serviceable in connection with other more or less varying forms of protectors. The showing in Fig. 15 therefore will be understood as being merely illustrative of one variety of the device that is referred to herein as a protector.

Fig. 14 shows in plan the top-lift of a heel for a boot or shoe having a series of protectors driven into the saine. In this case three protectors are shown, this being a number that frequently is employed in practice, and they occupy positions in the toplift at one side of the longitudinal axis of the lift and stand approximately radial with reference to the curved rear portion of the lift.

It will be obvious that in being driven the protectors have to be so held and guided as to cause the entering edge of each to rest on or strike the surface of the leather fairly, and also so as t-o cause the protectors to take the proper position in the stock. If the protector should occupy an inclined position in being driven the work would be spoiled, while if the protector in being presented to the driver should become swung around transversely with respect to its intended posit-ion it would not be driven in the proper position into the leather, and thereby the appearance of the work would be injured. Protectors of the form illustrated in Fig. 15 are essentially U-shaped, and heretofore in machines devised for the purpose of automatically driving or setting the same, they have been guided and positioned by means of a rib or iin provided in the machine adjacent the driving point in the latter, upon the exterior of which rib or fin the protector has been caused to slide, the said rib or 1in passing into the opening of the protector and constituting an internal guide for the latter while being driven. The use of this internal guide has been found disadvantagcous in practice, since it has necessitated the use of a driving pin or driver made U- shaped in cross-section at its driving end in order to clear thesaid rib or fin while forcing the protector into the stock. A U- shaped driver is frail and subject to injury, and it has been necessary in machines employing the same to replace the drivers repeatedly. The breakages and other injuries to the drivers interfere with the use of the machines and lessen their capacity and productiveness, while considerable expense has been entailed in replacing the drivers by new ones.

My present invent-ion simplifies the machines which are employed for driving or set-ting protectors, dispensing entirely with the internal guides located at the driving points in the machines, and enabling the U-shaped drivers to be replaced by solid drivers. rIhese last are practically free from liability to breakage or injury in the use of the machine, and hence rarely, if ever, require to be replaced.

In the drawings the drivers are shown at 5, in Fig. 1 and also in Fig. 9. rIhe number of drivers employed in a machine may vary in practice, but inasmuch as usually inthe case of toplifts of heels, three protectors are driven in a group as indicated in Fig. 14, it may be stated that three drivers 5 ordinarily will be employed in a machine used in driving or setting protectors into toplifts.

The drivers 5, 5, are secured to a driverblock 6, Figs. 1 or 9. They extend downwardly from the latter. The driver-block 6 is applied to or formed on the plunger 8, the latter moving in suitable guideways 81, which are provided in the head 9 of the machine, the said plunger being actuated in any suitable or approved manner, as for instance by means of a crank-pin 10 carried by an operating shaft- 11, the said crankpin being represented as furnished with av roll 12 working in a transverse slot- 121 with which the plunger 8 is furnished. As indicated in Figs. 1 and 9, the drivers 5, 5, are solid.

For the purpose of conveying the protectors to the place in the machine at which the drivers are arranged to act, suitable guides or raceways are provided as at 13, 13. These correspond in number with the drivers, and in practice protectors are applied to the guideways by hand or otherwise as preferred so as to furnish the necessary supply. Herein the guideways are shown constituted by strips which are suitably supported in proper position yin thc machine. A series of protectors is caused to straddle one edge of each of the said guideways.

15 is a block which is mounted in the machine in position below the drivers 5, 5, it being formed with a series of driver-passages 16, 1G, through which the protectors are driven into the stock which is to receive the same. The said stock is held in contact with the lower surface of the said block 15 at the time of driving. The block is shown carried by the head of the machine, and beneath the same is shown a work-supporting post 17, upon the up 3er end of which is mounted a work-rest 171 to receive the piece of stock which is to have protectors driven into the same. In practice, after the stock has been placed on the work-rest 171 at the top of the work-supporting post 17, the latter is forced upwardly so as to compress the stock against the under surface of the block 15. I have not shown the means of forcing the post 17 upwardly, inasmuch as the same forms no part of the invention and any convenient means of communicating vertical movement to the post 17 for the purpose of thus compressing the stock and of afterward releasing the latter may be employed in practice.

Above the block 15 formed with the driver-passages 1G, 16, I place a pair of plates 20, 21. These are mounted to slide transversely with reference to the said block and its driver-passages. I have herein shown the block 15 recessed in the top thereof to receive the plate 20, and the plate 20 in like mann-er recessed to receive the plate 21. rIhe block and plates being thus nested together they are held in their proper relationship by means of gibs 22, Q2, which are secured by screws 23, 23, to the block 15 at opposite Sides of the recess therein and over- 2 and 4 applied to the block 15 acts on the L plate 20 with a tendency to move the same to the rear in the machine. That is to say, to the right in Fig. 1. Plate 2() is constructed to permit of the passage of protectors therethrough. To this' endi it is formed with one or more openings or passages extending vertically through the same f as at 25, Fig. 2. At one side of the said passage or passages 25 the plate 20 is provided with a surface or surfaces 26 for engaging with the protectors. The plate 21v is likewiseformed with a surface or surfaces 27 for engagement with the protectors.` The normal position of the plates 20, 21, relative to the block 15 is as represented in Figs. 1, 2 and 3, the passage or passages through the plate 20 being located beneath the lower ends of the raceways 13, 13, and above a solid portion of the block 15 to the rear of the driver-passages 16, and the plate 21 being moved to the rear, also,- relatively to the plate 20 so as to separate the engaging surfaces 26, 27 to the maximum extent. As

the parts move rearwardly into this position, the bottom protectors on the raceways,

the said protectors having previously been supported by the top of plate 21, are capable of sliding or dropping from the said raceways into the passageway or passageways of the plate 2O until the bottom protector rests on the upper surface of the block 15. I provide means of causing relative movement of the parts which will cause the protectors in the said passageway of plate 20 to be clamped between the opposing engaging surfaces 26, 27, and then be carried forward in the machine so as to place them above the driver- passages 16, 16, and in line with the latter. Herein Ihaveshown a simple arrangement for the purpose comprising a lever 28, suitably hung to the head` of the machine, as upon a pin or pivot 29, and provided with a nose 30 arranged to be acted upon by a suitable moving part in the machine. In the present case the said nose is arranged to bear against the front of the plunger 8 under the action of a spring 31. In the construction of machine which is shown in'Fig. 1, the prominent portion 32 on the plunger acts inthe rise of the latter as al cam to move lever 28 to retractthe plates 20, 21 and hold them in the positions relative to the block 15 and to each other in which they are represented in Fig. 1. The

depressed portion 33 of the plunger in the.

descent of the latter allows the spring 31 to act to move the lever to shift plates 21 and 2O relatively to the block 15 so as to cause f'the protectors, first to be' clamped between fthe engaging surfaces 26` 27 of the two plates, and then be carried along upon the 1 block 15 into position in linek with and above lthe driver-passages' 16, 16.

As the two plates move forwardly the solid part of plate 21 passes under the next to the bottom protector on each raceway and supports the same and the others above the same on 1 the respectiverac'eways until in the retrac- 'tion ofV the plates the' passageway or passageways in the latter are presented again beneath the ends of the raceways. n

The engaging surfaces 26, 27 of the plates 20, 21, are so shaped with reference to the shape or Vform ofthe eXteriors o-f the protectors as that when the said surfaces are caused to approach each other by movement of the plates relatively to each other the contact of the said surfaces with the no-n-circular eXteriors of the protectors operates automatically to position the protectors prior to being driven. That is to say, the

said engaging surfaces 26, 27 are so shaped that whenthey are operated to clamp upon the protectors theycause the latter to adjust themselves, in case they shouldvnot stand eX- actly as in Fig. 14 until they' stand in precisely the positions which theprotectors are required to assume in the stock. Some yconsiderable variation in the shapes of the engaging surfaces 26, 27 vis possible. In Figs. 2 to 6, the engaging surfaces 26 are constituted by the surfaces of recesses shaped to receive the open ends of the protectors, the said open ends passing into the said recesses and the extreme ends of the sides of the protectors abutting against the straight inner surfaces of the said recesses. The engaging surface or surfaces 27 of the plate 21 are shown formed with concavities receiving the convex back portions of the protectors. Protectors dropped from the ends of the raceways into the passageway or passageways of the plate 20 and restingv on the upper surface of the block 15, may, and in practice frequently do, occupy positions varying considerably Afrom that which they finally are required to assume in the stock, but when the movement of the plates relative to each other takes place, the clamping of the protectors between vthe engaging surfaces 26, 27, will cause the protectors to so swing around transversely in a plane parallel with the entering edge ofa protector, and thereby re-adjust themselves in consequence of the pressure of the said surfaces against the prominent portions of the protectors, more especially at the open end of the protector, asv to give the protectors the same position which they should have in the stock. VHence, when the protectors subsequently are driven into the stock they -conform to requirements and present the required appearance.

lIt will be understood that the spring 31 acting on the lever 28 is more powerful than the spring 24, Fig. 2, applied to the driverbloclr 15 and acting against the plate 20.

.In Figs. 1 to 6 when spring 31 is permitted to lact to move the lever, the action is first to move plate 21 upon plate 20 until the protectors have become firmly clam ed between the engaging surfaces 26 and 2 after which the spring 24 yields and the plates 20 21 move together until protectors held by said plates are brought over the driver passages 16. See Figs. 2 and 6. This occurs during the descent of the plunger and drivers, and the plates 20, 21, remain in this position until the plunger and drivers complete their descent and begin to rise again. 'By the descent of the drivers 5, 5, the protectors are forced from the plates 20, 21 through the driver passages 16 and into the stock clamped between the work-rest 171 on the post 17 and the block 15. As the plunger rises and the prominent portion 32 of the plunger acts to move the lever 28, the said lever moves the plate 21 toward the right in Fig. 1. The plate 20 is moved in the same direction under the action of the spring 24, the extent of movement of the said plate 2O in such direction being limited, however, by means of a stop-pin 201, Figs. 2 to 6, projecting from block 15 into a slot 202 in plate 20, the said pin and slot being represented in dotted lines in said figures.

In some cases I dispense with the use of the spring 24 carried by the block 15 and acting against the plate 20, and instead thereof cause the said plate 2O to be held otherwise, as frictionally, so that it will not move relatively to the block 15 until a sufficient amount of power is applied thereto to overcome the resistance due to t-he friction. Thus, in Figs. 9 to 13, I provide'for producing a sufficient degree of friction against the plate 20 by means of a friction spring 41, seated in a recess 42 in the edge of plate 20 and compressed between the said edge and the adjacent side of the recess in the block 15 containing the said plate 20. In the case of the construction illustrated in the figures just mentioned, the spring 31 acting on lever 28, when permitted by the depression 43 of the plunger 8 to move the said lever, acts in the rise of the plunger first to move plate 21 relatively to plate 20 until the protectors have become com ressed between the engaging surfaces 26, 2 after which the frictional resistance to the movement of plate 20 being overcome, the plates 2O and 21 move in unison into their foremost position, thus placing the protectors above the driver passages 16, 16. This takes place as the drivers approach their highest position. The prominence 44 of the plunger acts during the descent of the plunger against the lever 28 to turn the same in opposition to the spring 31. The first result of this is to move the plate 21 upon plate 20, the latter remaining stationary. Thereby, the protectors are released and permitted to drop into the driver-passages, 16, 16. In consequence of the engagement of lip 45 of the plate 21 with the plate 20, the further movement of the lever 28 acts to cause plate 20 also to be retracted until plates 2O and 21 have been given their former position to the rear, with the passage 25 of the plate 2O in place below the lower ends of the raceways. This retraction of the plates 2O and 21 occurs in Fig. 9 during the first portion of the descent of the plunger and drivers.

Figs. 7 and 8 show certain modifications which may be made in the form of engaging surfaces 26 of the plate 20. In Fig. 7 I have represented the plate 2O as formed with a simple curved surface 261 in lieu of the recesses first described. The contact of the extreme ends of the sides of the protector with this curved surface 261, as the said ends are forced against such surface by the relative movement of the plate 21 and its engaging surface 27, causes the protectors to right themselves both vertically and horizontally in readiness for being driven. In Fig. 8 I have shown slight conveXities at 262, 262, against which the open ends of the protectors are caused to take bearing, a slight convexity at each place being all that is required in order to cause the protectors to right themselves These prominences or conveXities are intended simply to act against the eXtreme ends of the sides of the protector at the opening thereof, and it is not necessary that they should enter into the interior of the protector.
