VAMP-MARKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 454,987, dated June 30, 1891. Application filed September 23, 1890- Serial No. 365 L 920%. (No model.)

T 0 all whom it may concern..-

Be it known that I, JOHN F. ROGERS, of Belfast, in the county of Valdo and State of Maine, have invented certain new and useful Improvements in Vamp-Marking Machines, of which the following is a specification.

Thisinvention relates to machines for marking the toe portions of the Vamps of boot and, shoe uppers to indicate the proper position of the cap which is applied to the exterior of the vamp at the toe portion; and it has for its object to provide a machine capable of being adjusted to any and all sizes of Vamps and adapted to accurately mark the vamp of any size to which it may be adjusted.

To these ends the invention consists in the improvements, which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a top plan view of a vamp-marking machine embodying my improvements. Fig. 2 represents a side elevation of the same. Fig. 3 represents a bottom plan view,- and Fig. 4 represents a section on the line 5t at of Fig. 1.

The same letters and figures of reference indicate the same parts in all the figures.

In the drawings, a represents a supportingbed, which is preferably made in a single piece or casting, and is provided with screwholes I) to permit its attachment to a bench or table.

0 represents a holder or carrier 'for the vamp-marking devices, the latter being two pointed spurs (Z (Z, adapted to prick small holes in a vamp supported by the bed a, and a central blade 6, located between the spurs (Z (l and adapted to make a crease along the center of the vamp, the marks thus made enabling the operator to accurately place the toe-cap upon the vamp, the central mark enabling the operator to center the vamp in applying it to the top or quarters of the upper.

The marker holder or carrier 0 is here shown as a lever 5, projecting from a rock-shaft 6, which rock-shaft is mounted to turn on bearings in a slide or carriage 7, which is movable lengthwise, as hereinafter described, and segmental arms 8 8, extending laterally in opposite directions from the swinging end of the levee 5, as shown in Fig. 1.

The spurs cl cl are aflixed to two levers f f which are pivoted at their inner ends at g g to the base or inner end of the lever 5 and arecurved at their outer ends so as to partially plied to'either lever, so that in adjusting the levers to vary the distance between the spurs cl d and adapt said spurs to Vamps of different widths it is only necessary for the operator to take hold of one lever and move it to the desired distance from the center marker 6, the other lever and the spur thereon being moved by the described connection between the levers an equal distance in the opposite direction. The levers and the spurs cl thereon are thus kept equidistant from the central marker 6 and adjusted simultaneously, so that they can be quickly adj usted to position to mark any desired size of vamp. The segmental guiding-arms 8 8 are concentric with the pivots g g of the levers, so that the curved ends of the levers move freely upon the guidearms without binding or crowding thereon.

The leverf is provided'at its outer end with a set-screw h, which is arranged to bear upon the upper side of the arm 8,011 which it moves, and thereby directly secure the lever f to said arm, and at the same time indirectly secure the lever f in position upon its guiding-arm through the gearing that connects the two levers.

The center marker (2 is adjustable longitudinallyof the holder or carrier 0 by means ofa screw-threaded stud j, aflixed to said marker and projecting through a slot 7: in the lever 5, and a nut Z, engaged with the upper end of the stud j, said nut when turned down upon the upper side of the lever 5, causing the marker 2 to bind closely against the under side of said lever in a manner which will be easily understood. The marker 6 can therefore be caused to extend over more or less of the upper surface of the vamp to be marked.

The marker holderor carrier is normally held in the raised position shown in Figs. 2 and 4 by a spring m on the rock-shaft 6, one end of said spring being secured to the bed a and the other end to the inner end of the lever 5.

When the operator desires to impress the marking devices upon the vamp,he depresses the carrier or holder 0 by means 01: a treadle (not shown) connected with the lever 5 by a rod 71, said rod passing through an enlarged opening 0 in the bed a. i

The bed a is provided with blocks 19 p of wood or other comparatively yielding material under the point where the marking devices act upon the vamp, said blocks preventing injury to the marking-spu rs, which would take place if the spurs came in contact with a metal surface in penetrating the vamp. Between the blocks 1') p is another block q of yielding rubber or other material, which is comparatively elastic. Said block q being arranged over the marker 6 and intended to permit the vamp to yield under the pressure of said marker, so that the latter will not make too deep and permanent a crease in the vamp, it being desirable to have the marker 6 make only a faint crease, which will not be visible in the completed boot or shoe.

0* 7' represent two adj ust-able guides or gages supported by the bed a and arranged to bear against the inner edges of the recess in the rear portion of the vamp. The forward ends of said levers are pivoted at s s to slides t i, which are adapted to move in guides or ways in the bed ct, crosswise of the latter. On the inner sides of said guides are formed wings at it, having beveled rear edges 9 9, which bear against a stud or pin 10, affixed to an adj ustable slide or bar 12', said bar being provided with a longitudinal slot 13, which receives a fixed guiding-stud 1i, projecting upwardly from the bed a, and a fixed pin 15, which also projects upwardly from the bed, said stud and pin holding the bar 2 in a position parallel with the sides of the bed, and permitting said bar to be moved lengthwise of the bed. lVhen said bar is moved forward or toward the marked holder 0, its stud 10, bearing against the beveled edges 9 of the wings it, forces the said wings and the guides r to which they are attached outwardly in opposite directions, thus increasing the distance between the guides r, the slides t t moving outwardly in opposite directions in their guides or ways. hen the bar 12 is moved backwardly in the opposite direction, the guides r are pressed inwardly by a spring 16, which is located under the bed and is engaged with the guides r by means of its upwardly-bent ends, the tendency of said spring being to press the guides r inwardly toward the bar 12.

The guides 1' may be caused to assume various inclinations, so as to conform to the shape of the sides of the recess in the vamp by means of the levers 17 17, which are mounted to turn upon the stud 15, and extend outwardly from said stud so that their swinging ends bear on the inner sides of the guides 0', as shown in Fig. 1. Said levers may be adjusted by means of a movable stud 18, which passes through the slot 13 in the bar 2, and is provided with a c1amping-nut 19, whereby it may be secured to the bar 12 at any pointwithin the range of its adjust ment in the slot 13.

The levers 17 17 bear against the stud 18, as indicated in Fig. 1,50 that by moving said stud forward the swinging ends of the levers will be forced outwardly, thus swinging the rear ends of the guides r '1- outwardly, while by moving the said stud in the opposite direction the levers are allowed to be forced inwardly by the pressure of the spring 16, and thus permit the rear ends of the guides r 1' to approach each other.

The guides r a and substantially the means above described for adjusting and securing the same are shown in Letters Patent No. 429,389, granted to me June 3, 1.890, the principal departure from the construction shown in the above patent being the slides t t, to which the forward ends of the guides r *r are pivoted, said slides giving the guides a more substantial support at their forward ends than the arrangement shown in the said patent, in which no such support is provided, the guides being shown in said patent as pivoted to the swinging ends of the levers corresponding to the levers 17, here shown. It will be seen that the employment of the slides t tenables me to dispense with a positive connection between the levers 17 and the guides, so that the adjustment of said levers does not change the longitudinal position of the guides 1 2'. The spring that presses the guides 7' 0' inwardly is shown in my other patent as located above the bed, while in this case the said spring is located below the bed, and is therefore out of the way and protected from injury.

The slide or carriage 7, supporting the bearings of the rock-shaft that supports the marker-carrier, is movable toward and from the guides r r,.as in my former patent; but in this case I have provided improved means for adjusting said carriage and the markercarrier, which means I will now proceed to describe. To one end of the carriage 7 is afiixed a rod 20, which is fitted to slide in guides 21 21 on the bed a. To said rod is affixed a rack 22, with which engages a pinion 23, formed on a lever 52%. Said pinion is mounted to oscillate upon a stud or pivot 25, atlixed to an ear 2U on the bed a. It will be seen that by moving the pinion by means of the lever 2a in one direction or the other the carriage 7 and the marker-carrier will be moved toward or from the vamp-guides v' 'r, as the case may be.

27 represents an indicator, which determines the position theleverfll should occupy to adjust the marker-carrier to any given size of vamp. Said indicator is a segmental bar or plate having a series of orifices 28, which orifices are concentric with the stud or pivot 25, upon which the pinion 23 turns. The lever 2i is composed of two sections, the inner one ol' which is formed on the pinion 23, while the outer one is pivoted at 29 to the inner, and is provided with a pin 30, adapted to enter either of the orifices 28, and thereby engage the lever with the indicator in as many positions as there are orifices in the indicator. Each orifice 28 is accompanied by a number lmpressed upon the indicator, each number giving the size of the upper to which the markers are adjusted by the movement of the lever 28 into engagement with the orifice. For example, if it is desired to adjust the markers to a vamp of the No. 8 size the lever.

24: is moved into engagement with the orifice marked 8, and so 011. Some of the orifices are marked to indicate one series of sizes, as for mens and boys boots, and the other a different series of sizes, as for ladies and misses shoes.

It will be seen that the indicator enables the operator to quickly adjust the markercarrier for any size of vamp, it being only necessary to move the lever to the orifice bearing the number of the size of the vamp to be marked.

The carrier 7 is adj ustably secured to the rod 20 by means of a socket 31, formed on the carriage, said rod passing through said socket, and a set-screw 32, passing through one side of the socket and bearing againstthe rod. The rod is preferably provided with a series of marks or graduations to guide the operator in adjusting the carriage 7 upon the rod when it is desired to effect an independent adjustment of the carriage.
