WELT GRGOVING AND BEVELING MACHINE.
Specification of Letters Patent.
Patented Oct. '7, 191.3.
Application filed May 17, 1913. Serial No. 768,285.
I '0 all whom it may concern Be 1t known that I, HARRY Lyon, a citizen of the United States, of Brockton, in the county of Plymouth and State of Massa=v chusetts, have invented certain new and useful Improvements 1n \Velt Groovlng and Beveling Machines, ofwhich the following is a specification.
This invention relates to machines for grooving one side of a strip of leather or other material suitable for welting for boots and shoes, and for forming a beveled face on one of the edges of said strip, or for performing either, of these operations, thetwo operations being preferably performed simultaneously. y
The invention is embodied in a machine havin a lower and an-upper strip-feeding roll, t e lower roll being journaled in fixed bearings and being accompanied by a fixed beveling knife, adapted to act on one edge of the strip, .while the upper roll is journaled in movable bearings, and is adapted to be moved'toward and from the lower roll and conform to the thickness of the strip ,between the rolls, the upper roll being accompanied by a grooving-knife, which is also movable toward and from the lower roll and the beveling knife, so-that the machine adjusts itself automatically to the thickness of the welt strip and is adapted to form a groove of uniform depth, regardless of the thickness of the strip, and also to bevel the edge of a strip of any thickness.
The invention is also embodied in a machine characterized as above stated, and pro vided with an adjustable gagefmthe inner edge of the welt strip,said gage being adapted to be quickly adjusted to the width of the strip, and to be automatically locked in its adjusted position.
The nature and objects of the invention are more fully set forth in the following specification, and the novel features are pointed out in the claims.
Of the accompanying drawings forming a part ofthis specification,--Figure 1 represents a top plan view of a machiiiie embodying my invention, a part of the machine being shown in section. Fig. 2 represents a side elevation of the machine. Fig. 3 represents a partial section on'line 33 of Fig. 2, and an elevation of parts at the left of said line. Fig. 4; represents a front elevation of the entire machine. Fig. 5 represents an elevation of the side opposite that shown by Fig. 2. Fig. 6 represents a section on line 66 of Fig. 1. Fig. 7 represents an enlarg ment of a portion of Fig. 1,, the upper feeding roll and other parts being removed.
Fig. 8 represents a section on line 88 of Fig. 7. Fig. 9 represents an enlargement of a portion of Fig. 2. Fig. 10 represents a section on line l010 of Fig. 1. Fig. 11 represents a section on line 11-11 of Fig. 9, and an elevation of the parts at the right of said line. Fig. 12 represents a perspective view of the part hereinafter called the-face plate. Fig. 13 represents a perspective view of the grooving-knife supporting-arm. Fig. 14 represents a perspective view of the grooving-knife. Fig. 15 represents a perspective view of the beveling knife. Fig. 16
represents a perspective view of a welt strip partially grooved and beveled.
The same reference characters indicate the same parts in all of the figures.
12 represents the base of the machine frame to which are affixed standards 13, having upper bearings '14, for the drivingshaft 15, and lower bearings 16 for the shaft- 17 which carries the lower welt-feeding roll 18, the upper ends of said standards being offset, as shown by Figs. 4 and 10, so that the shaft 15 is located at one side of and above the shaft 17. .The driving-shaft ha the usual fast and loose helt pull ys 20 and 21, and a driving gear 22, located bet-ween the bearings 11. Au ii'iterm'e'diate gear 23, the shaft of which is journalcd in hearings in the standards 13, connects the driving gear 22 with a gear 24 on the lower feed roll shaft 17.
represents theupper welt-feeding roll, the shaft 26 of which is journaled in movable bearings 27 on a swinging yoke or frame 28 (Fig. 1), adapted to swing on the driving-shaft 15, said yoke being preferably provided with tubular trunnions 2). forming bushings for the bearings 141, and adapted to turn therein. A gear 30 attached to the upper feeding-roll shaft 26, meshes with tie driving gear 22.
It will now be seen that the upper feeding roll is adapted to be raised and lowered relatively to the lower feeding roll 18 andto a welt strip 31 interposed between said rolls, the upper roll being thereby adapted i to conform to the thickness of the welt strip and to be raised to entirely clear the same as indicated by dotted lines in Fig. .10. The downward movement of the upper roll may be limited by a fixed stop member 32 on the base and a movable stop member provided by a neck 33 formed on'or attached to the bearings 27 and yoke 28, and extending screws 36, 37. Said face plate has a. down wardly projecting finger 38, adapted to bear.
on the outer end of the knife 43, above the U shaped portion of the cutting edge, and also to bear lightly on the upper surface of the welt strip, said finger preventing the upper surface of the portion of the welt in which the groove is formed from being raised or bent upwardly by the knife. The
plate 35 is provided with a curved slot 39 which receives the screw 37 and permits the plate to ,swing on the screw 36 to adjust-the finger 38'. The groovingknife 43 has a shank 44 which is attached by a screw 45 to an arm 46 ad-- justably secured to the face plate 35, said arm having a slot 47 which receives the screw 45, and permits a vertical adjustment of the knife 43. The arm 46 has a socket 48 which is-divided at one side and is adapted to receive a stud 49, affixed to the plate 35. The arm 46 is adapted to turn on said stud for the purpose of adjusting the knife 43 to a bearing on the finger 38. 'The socket 48 is adapted to be contracted on said stud to secure the knife in its adjusted position, the arm] being provided for this purpose with cars 50 a justably connected by a screw 51..
Ascrcw 52 adjustable in a tapped ear'53 on the plate 35 bears on an ear 54 on the arm 46, and is adapted to turn the arm on the stud 49 when the screw 51 is loosened.
It will be seen from' the foregoing that the grooving-knife 43 is adjustably-mounted on the frame which carries the upperfeeding roll and is movable with said roll toward and from the lower feeding-roll and the interposed welt strip.
55 represents a fixed strip-supporting bed supported by a fixed standard 56 on the base, the upper surface of the bed being tangential to the lower feeding-roll 18, as
shown by Fi 3. The welt-beveling knife 57 (Fig. 15 is supported by the bed 55, said knifehaving aslotted shank 58,
which is attached by a scr ew 59 to a.- projection 61, (Fig. 4) on a strip guide or gage 60 which is secured to the bed 55 by a screw 62, passing through a slot 63, (Fig. 7 in said gage. The cutting edges of the grooving and beveling knives are arranged to form a groove in the upper surface,
' and a beveled face 66 on one edge of the welt strip, as indicated by Fig. 16. The gage 60 bears on the outer edge of the welt strip, as indicated by Fig. 7. The beveling-knife is rendered adjustable by the slot 63 and screw 62, to compensate for wear of its cutting edge.
67 represents an inner gage or guide for the inner edge of the welt strip, said gage being adjustable toward and from the fixed gage 60, and provided with means whereby it may be quickly adjusted to the width of the strip, and automatically locked inits adjusted position. The adjustable gage 67, which isbest shown by Figs. 7 and 3, is a plate formed to slide on the bed 55, and provided with a guiding face 67" against which "the inner edge of the welt strip bears. The
under sideof the gage plate 67 is provided with a projection 69, andthe bed is provided with a slot 70 in which the projection is movable. The slot and projection have parallel edges and the projection is narrower than the slot, so that its edges are movable out of parallelism with the edges of the slot, as shown by dotted lines in Fig. 7, two diagonally opposite corners of the projection being therefore ada 'ited to be held in binding or locking engagementwit-h the edges of the slot. A spring 71 connected at one end with a hook on the projection 69 and-at the other end with a hook on the standard 56, normally holds the projection 69 in looking engagement with the sides of the slot. The gage plate 67 is provided with a handle 72 by which the operator may turn it to loosen the projection 69, and. permit free movement thereof lengthwise of the slot 7 O, for the purpose of laterally adjusting the gage face 67. When a welt strip is applied to the machine, the upper feed roll risesautomatically, it being raised by the welt strip. The operator places the outer edge of the strip against the fixed gage 60, and at the same time manipulates the handle 72, to release the projection 69, -so that the gage plate 67 is free to adjust itself to the width of the strip. When the stripis in place between the two gages, the operator re leases the handle 72, and the gage plate 67 is automatically locked in its adjusted position.
The feeding-rolls 18 and 25 are rotated by the described mechanism in the directions indicated-by the arrows in Fig. .3, and the knives '57 and 43 are arranged to engage the strip at points close to or beside the nip of the feeding-rolls, so that the rolls do not exert a pulling-strain on the portion of the strip which isengaged by the knives, but
instead, push said portion against the knives. Hence, there is no liability of stretching the strip and temporarily reducing its thickness at the point where it is being'cut, when the strip is of soft and stretchy material. Thes'lsopth of the groove formed in the strip is therefore uniform. The upper feeding-roll and the grooving-knife being mounted, as described, on a frame which is jonrnaledto swing on the axis of the driving gear 22, the torque of said gear exerts a downwardpressure on theeupper feedingroll and holds it against the welt strip with a pressure which is not affected by the thickness of. the strip. Said pressure is however affected by the resistance offered by v the knives to the feed movement of the strip, so that when the knives are dull and offer an increased resistance, the downward pressure" of the upper feeding-roll is increased in proportion to the-resistance. The positive feeding of the strip against relatively dull knives is thus insured and the pressure maintained at all times at no more than the degree necessary to cut and feed the strip. hen the knives encounter relatively soft portions of the strip, the pressure is diminished, so that the soft portions are not unduly compressed bv the feeding-rolls.
