STATE@ PATE l WILLIAM J. NOON, OF LYNN, MASSACHUSETTS, ASSIGNOR OF ONE-HALF T0 SIMEON J. ROUSSEAU, OF LYNN, MASSAQHUSETTS.

To all whom tt muy concern:

Be it known that I, IVILLIAM J. NooN, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and usei'ul Improvements in Counter-Guards, ot which the following is a specilication.

This invention relates to counter-guards used in connection with heeltrimming machines to protect the upper leather at the counter of the shoe from being injured by the cutting tool.

The invention consists in a means olf mounting the guard or lip so that it may move outward from the base of the cutter when the thickest or most sharply beveled portion of the heel is turned toward the cutter, and of guiding the guard so that when so moving` it will follow the path conforming to the tinal curvature ot the heel.

More particularly the present invention is an improvement on the device described and claimed in my pending application for counter-guards led. May 27, 1908, Serial No. 435,295, and consisting in improvements in the details of construction, especially of means by which the guard or lip is adjusted in a direction transverse to the axis of rotation of the cutter.

In carrying my invention into effect I Ahave, devised a mechanism of which the construction at present preferred by me is illustrated in the accompanying drawings, in which,-

Figure 1 represents a plan view of the device in the relation which it occupies to the cutter of a heel-trimming machine. Fig. 2 is an end elevation of the device as it appears when viewed from the right. Fig. 3 is a section taken on the line 3--3 of Fig. 1 looking in the direction ot' the arrows. Figs. a and 5 are perspective views of the holder by which the templet or guide for the counter-guard is carried, and of the templet itself respectively.

The same reference characters indicate the same parts in all the figures.

Referring to the drawings I have designated conventionally at 1 the rotary cutter of a heel-shaving or trimming machine, this cutter being conveniently any of the wellknown types now in use, and being shown here for the purpose of illustrating its relation to the guard which Jforms the substance of the invention.

Specification of Letters Patent.

Application filed November 5, 1909.

COUNTER-GUABD.

Patented Feb. 14, 1911. Serial No. 526,355.

embodied consists of a lip or guard plate 2, which is adapted to enter the crease between the heel and upper leather at the heel seat to protect the upper from injury by the cutter, a holder 3 to which said lip is connected, a bed plate fl which supports the guard holder by pivotal means hereinafter described, and a bracket 5 secured to the column or base of the heel-shaving machine in any convenient manner. The bed plate l has a tongue 6, which isadjustably secured between under-cut guideways 7 of the bracket 5. As clearly shown the tongue may slide longitudinally between these guideways, and is secured by a bolt 8 passing through ears 9 on the guides and a clamp 10 threaded upon the end of the bolt and bearing against one ot said ears. A stop screw 11 threaded through a lug 12 on the bracket 5 and bearing against a shoulder 13 on the tongue 6 serves for adjusting `and limiting the inward movement of the bed plate l.

rlhe means for connecting and supporting the guard holder 3 on the bed plate 4t consists of a bracket 111 secured to a pivot pin 15, which preferably passes through the bed so that it may be connected to the bracket both above and below the bed, and an arm 16 pivotally mounted upon a stud 17 which is secured adjustably to the bed. The bracket 14 has parallel guideways or pas sages through which extend rods or bars 18 secured in any desired way to a bracket 19 which is pivoted by studs or screws 20, 21 to the guard-holder It should be noted that the guard-holder is a piece, preferably a metal casting, which has the form ot a ring at the end nearest the cutter 1 and arms 3 extending from diametrically opposite sides of the ring away from the cutter parallel with the axis ot' the ring, being connected together at their remote ends and provided with a lug 3b. The pivotal members 20 and 21, which connect lugs 22 of the bracket 19 to the guard-holder 3 are attached to the latter at diametrically opposite points in line with the arms 3a in a pivotal manner. The lug 3b at the end ot the guard-holder is connected by a pivot stud 23 with the end 16a previously described.

The guard holder and guard are normally urged toward the base of the cutter, that is, toward the right with respect to Fig. 1 by The apparatus in which my invention is springs 2.4 and 25. The former of these Y ing ends of the bars 18.

surrounds the stud and the lattei` surrounds the hub 1Gb of the arm 1G and is engaged with a projection 1GC on the side of said hub. The ends of the springs are engaged with studs 2G, 27 respectively fastened in the bed plate 4 in such a way as to exert a thrust in the desired direction. There are two sets of studs located so that t-he ends of the springs 24 and 25 respectively can be engaged with any one of them for adjusting and thereby increasing or diminishing the force exerted by the springs.

On the side of the lip holder next to the bed plate is fastened an arm 2S carrying an anti-friction roll 29 which is held against a templet or guide 30 in a yielding manner. The surface ofthe templet against which the roll bears is curved to conform with the curvature of the cutter blades and of the final form of t-he heel. The roll is held against the templet by means of springs 31 surrounding the rods or bars 1S, and exerting force between the bracket 14 and abutinents 32 secured adjustably on the project- The tendency of these springs, as will be. seen, is to draw the rods or bars through the bracket 14 and retain the roller Q9 in contact with the surface of the templet. By this means, as the vguard is moved back and forth it travels in a curved path and approaches the axis of rotation of the cutter when the deepest part of the heel is turned toward the same. It is to be noted that the arm or bracket 2S has curved arms 28 which lie against the circular portion of the guard holder 3 and are secured thereto by fastenings 33 It is desirable to provide for varying the position of the path of the counter-guard and also the outline of said path. For this purpose the templet or guide 30 is mounted adjustably and is detachably connected with its holder so that the templets may be readily removed and interchanged. Therefore the templet is made as shown inl F ig. 5 as a block provided with an aperture 34. This block is laid between the ears 35 of a holder 36 and secured thereto by a pin 37 passing through apertures 3S in the ears which are in line with the perforation 34 of the templet. When thus held in the holder, the templet bears against the Hat base portion thereof s0 that it is accurately positioned. The holder has a shank 39 which passes into -a socket in the bed plate and is held from be instantly altered to correspond with the Y-cutter employed and the style of heel, permitting the heel to have the required amount of extension beyond the heel seat of the shoe. Y

Moreover by removing' the pin 37, one templet may be removed and another substituted instantly. The lock nut 42, which has a handle 43 in an accessible position, where su'liicient power may be exerted for crowdjournalcd in the bed plate 4 and. passing through. a threaded aperture in the base of the stud 17. This stud is contained in a slot 45 wherein it may be moved, and has a flange 4G resting on the upper surface of the bed plate and a nut 47 threaded upon it beneath the bed plate. By means of the nut and flange it is clamped or mounted without looseness in the bed plate. By means of the adj usting screws 41 and 44 either or both ends of the counter-guard may be shifted toward or from the axis of the cutter. The range of movement of the counter-guard in the direction of this axis is limited by stop screws 48 and 49 threaded into lugs on the base plate on each side of the arm 1G. These stop screws are provided with clamp nuts 50 by which they are 'prevented from being jarred loose.
