HENRY 'vnoonnn or noSToN, MASSACHUSETTS.
Letters PcttentNo. 107,641, dated September 20, 1870.
IMPR'VEMENT IN' ROUNDING--UP MACHINES FOR SHOES.
1', l' The Schedule referred to-n these Letters Patent and making part of the same.
' To all whom it may concern Be it known that I, HENRY S. VROOMAN, ofoston, in the county of Suffolk and State of Massachusetts, have invented an Improved Machine for Rounding-up Boot and Shoe-Soles; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a descii tion'of my invention suiiicient to `enable thoseskill in the alt to practice it.
My invention relates to details of construction and arrangement `of parts of machines designed particu larly for rouncbngfup boot and shoe-soles, or trm ming their edges to proper shape, a Vpattern-plate,
withV the sole-forming leatherplaced beneath it, being fed through two feed-rolls, back of which rolls is an edge-gauge and also a cutter, the gauge being so 1o-` catedthat'lhe edge of the pattern-plate vonly comes in contact with it, while the cutter is so located that the leather beyond the edge of the gauge is trimmed oit' near to the gauge, the shaving or waste passing through a suitable throat on the inner side of the cutter.
My invention consists in attaching this gauge tov the levcror vertically-movhlg arm, in which the upper feed-roll shaft is journaled, so that the rise and fall `of the arm always keep the gauge in proper position,
relatively to; the varyhnglythick sole, as the latter is fed' throughthc rolls. I
`The invention alsoconsists in combining, with a gange and top pre'sserroll, both fixed to a movable arm orlever, a spling, holding the presser-roll down to the smfaceof the soleor pattern-plate, and in combining, with this arrangement, a lever for relieving the feedlroll from-the 1stressofthe spring, to permit the introduction oi' a pattern-plate, and a sole to be trimmed. l
Another feat-nre oi' the invention consistsl in the employment o1' a pattemplate, provided with a series oi' teeth on its surface, against `which the-sole is placed,
the teeth Ventering the sole, and preventing it from slipping onj the patternlplate.
The drawing represents a machine embodying my improvements. i l y p 'A shows a side elevation of the machine. I B, an oppositeside-elevation.
O, a front view'of it.` 1 K Y D, a plan of the front art of the machine.
E is a viewof' the un er side of the pattem-plnte.
u. denotes the frame of the machine, in whichis journaled a shaft 11, carrying at its front end a toothed feed-wheel, c, an at its rearend a oearlwheel, d, which -k `wheel'is driven by any suitable mec ansm, and meshes into and drives a pinion, e, on the rear end of a shaft, j-at whose frontend is theupper and smooth feed` roll` g, located 'directly over the toothed feed-wheel c.
vThe' shaft f turns in bearings on a lever 1t, which is pivoted at its rear end to the main fram at t', and is fastened to the frame, near its front end,` yx screws, L, passing through slots, l, in thelevfe-r, the slots permit-ting slight vertical movement of the front end, of the lever.
Just in rear of the feed-roll g is an`edge-gange, an, thc shank-of which extends up,.and is fastened tothe lever h by screws, n, the gauge being xed relativelyto the lever, and moving with it, thoughv it is adjnstably fixed to the lever, so that it may be set higher or lower, as thethickness of the pattern-plate may render necessaryor advisable.
The lever and gauge are drawn down bythe stress of a strong spring, y, the top of the spring pressing ,against a projection from the main frame, and thebottom against a nut'and washer on the lower end of a rod, o, whose upper end isjointed to the lever.
The foot of the rod extends through alever, l, fulcrumed'to the main frame, at g, the' rear arm o this lever being extended, and having at .its en'd a hook or other provision for attachment of the rod of apedal on the Hoor beneath the machine. By drawing down this lever-arm, the rod o is raised, and the topfeed roll thrown up from the feed-roll c.
The gaugem extends down below the` horizontal plane of the bottom of' the top roll, a vdistan'oeequal to the thickness of the pattern-plate, the plate and sole being introduced between the rollsrwith the plate uppermost. A
In line with the frontvof the gauge, and "with its cutting-edge close thereto, is a vertical knife or cutter, o', fastened at lower end toa block, s, xed to the frame a, and at its upperrend to an arm, i,projecting from. said block there being' a throat or ace, fu, between the arni and block, as seen at Aand The parts beimlr thus constructed nd arranged, the metal pattern-ph e t', with the lcat r blankor soleforming piece fw laida inst it,is introduced between the feed-rolls, (patterauppermosn) the lever 71. being raised by the lever l), to )ermit flee 'entrance of the pattern-plate and so e-b After such entrance the release of the lever causes the feci-roll to bear down hard u on the surface of the pat .ernplate,4 so that as the eed-wheels are rotated, the movement of the eatherand attern-plate togetheris insured. As the pattern-plat?)I is held up to-the face of the edv@- gauge, the knife o r cutter trims ofi' the stripof leather progecting beyond said pattern-plate, and passing under it, the cutfoi 'strip or chips escaping through the threaten As .the'"periphery of the uppei` feed-roll is smoothsurfaced, andasV the feed-tceth of the lewerroli' not only ou the leather', some provision is. necessary to keep the sole in xed position, relatively to the pattern-plate, while they are moving through the feedrolls. For this purpose I serrate the surface ot' the pattern-plate which is in contact with the sole, or cover such surface with a series of small spurs or teeth, which, by the compression of the sole between the rolls, are forced into the leather, and prevent the sole from slippin g.
Instead of making th smooth roll andgauge-frame movable, the frame to which the toothed feed-wheel is attached may be made movable; or the lower wheel may be journaled in a movable frame, orin movable journals, and the smooth roll in fixed journals, the gauge being held in positionVrelatively to the smooth feed-wheel, by a suitable spring acting from that portion of the frame in which the toothed feed-wheel is journaled, the object of the invention, namely, to control the position of thegauge relatively to the smooth feed-wheel, being accomplished by either of these mo'd-. itications. I prefer, however, and arrangement shown.-
the specic construction I claim- 1. In combination with feed-wheels and a roundingup knife, a gauge, so arranged that the arm or frame, in which the upper and smooth roll is journaled, controls the position of said gauge.
2. In combination with a rounding-up knife, and with the gauge and smooth'feed-roll, relatively fixed and located as described, a power-spring for producing the pressure upon the sole and pattern-plate between the feed-wheels. I
3. In combination with said knife, feed-rolls, gauge, and spring, the rod o and lever p, so arranged that the stress of the spring may be reduced by the lever, to separate the rolls for introduction ofthe sole.
4. In combination with the feed-rolls, edge-guide, and roundingmp knife, a metal pattern-sole or plate, one surface of which is toothed or serrated, substantially as shown and-described.
