MACHINE FOR CLIPPING HATS, FURS,&.0.

SPECIFICATION formingpart of Letters Patent No. 271,423, dated January 30, 1883,

Application filed October 26, 1882.

To all whom it may concern Be it known that we,lHOMAs OOLDWELL and WM. H. GOLDWELL, of Newburg, in thecounty of Orange, and in the State of New York, have invented certain new and useful Improvements in Machines for Clipping Hats, Furs, 850.; and we do hereby declare tha-t thefollowing is a full, clear, and exact description thereof, reference beinghad to theaccompanying drawings, making a part of this specification, in which- Figure l is a perspective View of our machine as arranged for use. Fig. 2-is a plan view of the upper side of the same, showing one form of mechanism for holding the hatbody and for causing the same to pass in front of the clipping mechanism. Fig. 3 is a like view of said machine, and shows the holding and feeding mechanism preferably employed, as seen in Fig. l; and Fig. at is a vertical section upon line 00 :r of Fig. 5.

Letters of like name and kind refer to like parts in each of the figures.

Ourinvention is more especially intended for use in the clipping of hat-bodies, but is equally applicable to the dressing of any article having a nap-surface and to furs; but as the principle of operation is the same in each case it will be a sufficient illustration of said invention to show its application to the first named of said articles.

Thedesign of our invention is to enable the hairs or threads which form the surface of a hat-body to be evenlyand expeditiouslyclipped to a uniform length; and to this end said in vention consists principally in the method employed whereby thehairs or threads are caused to maintain a position at or near aright angle tothe plane of the cut, substantially as and for the purpose hereinafter specified.

It consists, further, in the means employed for cutting or clipping the hairs or thread, substantially as and for the purpose hereinafter shown.

It consists, further, in the means employed for holding the hat-body, while being clipped, in position to be operated upon by the cutters, substantially as and for the purpose hereinafter set forth.

It consists, further, in the means employed for moving the liat-bodyin front of the cutters,

(No model.)

substantially as and for the purpose hereinaf ter shown and described.

It consists, further, in the means employed for drawing the hat-body,while being operated, up tightly over the bearing cone or bar, substantially as andfor the purpose hereinafter specified.

It consists, further, in the construction of the cutting mechanism, whereby the entire outer face of the hat-body may be clipped at one operation, substantially as is hereinafter shown.

It consists, further, in the means employed for causing the nap to lie in onedirection, and for preventing bagging of the hat-body while being clipped, substantially as is hereinafter set forth.

Itconsists, further, in the means employed for adjusting the cutters, substantially as and for the purpose hereinafter shown and described.

It consists,finally,in the machine as awhole, constructed and adapted to operatein the manner and for the purpose substantially as hereinafter specified.

In the annexed drawings, A represents a horizontal rectangular frame, which is provided with four legs, B, and furnishes a sup port for the operative mechanism.

Journaled transversely at a point near one end of the frame A is a wiper, (3, consisting of a central portion composed of three spiral radial arms, 0, that at their ends are connected together, and two journals, c, which are arranged at opposite ends of said arms, and are contained within suitable bearings, D, that are attached to the upper side of said frame. Said bearings are made horizontally adjustable in a line having a right angle to said journals, while set-screws 61, passing inward through suitable lugs, d, attached to said bearings, enable said wiper to be adjusted longitudinally. The outline of the central portion of the wiper 0, from one end nearly to its opposite end, is that of a straight cylinder, while at the latter point each arm 0 extends outward in the form of a curve, as shown in Figs. 2 and 3. Said wiper is rotated by means of a shaft, E, which is journaled within suitable bearings at one end of the frame, and is provided at each end with a band-wheel, F, from which a band, Gr, extends to and around a pulley, H, that is secured upon the correspondingjournal, c, of said wiper.

Immediately in front of the wiper O is a stationary cutter, I, which has in cross-section the form shown in Fi 4, and longitudinally correspondsto the line described by the wipers c. The face of said cutter adjacent to said wiper is vertical and its opposite face inclined, so as to give to it greater thickness at its lower edge than at its upper edge. Said upper edge has a downward bevel from said wiper and presents a sharp edge to the impingement of the arms of the latter.

The wiper O is inclosed by a casing, K, at

its upper and lower sides, and in front to within a short distance of the upper edge of the cutter I, while at the rear side of said wiper, within said casing, is an exhaust-fan, L, which is driven by means of a belt, I, and pulleys l and I from the shaft E, and causes a constant current of air to pass over the edge of said cutter I into said casing,and through the same into a suitable discharge-pipe connected with the rear portion thereof.

In front of the cutter I is a bar, M, which in cross-section has the form of a wedge with its point rounded, as shown in Fig. 4, and in plan view has such form as to cause its rounded edge to conform to and correspond with the .edges of the wiper-arms c and of the said outter I The bar M is supportedat its outer end by a brace, 11:, and at its inner end is hinged to or upon the frame. The inner end of said brace is also hinged so that said bar may be turned upward, as hereinafter described. The bar M is intended for use as a bearing over which to stretch a hat-body, and has such length as to enable it to receive the largest size. Said hat-body is placed over said bar, (the latter being raised, as before described,) with the apex of its cone immediately over the curved or rounded end of said bar, from which end said hat-body extends around the face of said bar in front of the cutting mechanism and occupies the general position shown by dotted lines of Fig. 3, when, by setting in motion the wiper O and causing said hat-body to be fed or moved over said bar, so as to bring every part of the outer face of the former into suitable position, the nap will be clipped by the action of said cutting mechanism. The current of air moving into the casing K through the opening over the cutter I causes the hairs of the nap to be drawn horizontally outward over said cutter and to be held in such posi' tion while being acted upon by the clipping mechanism, by which means each hair is clipped to a length corresponding to the lengths of the other hairs, and the nap is left with a perfectly uniform and smooth surface.

In order that bagging of the hat-body may be prevented and the nap caused to lie in one direction, a comb, N, is secured upon suitable supports above the bar I, with its toothed edge in position to engage with the upper surface of said hat-body at a point slightly in rear of the front edge of said bar. In consequence of said comb, all fullness or bagging of said hatbody in spots is kept in the rear, and it is caused to pass over or around the edge of said bar in asmooth, even manner, rendering practicable the production of a nap having a uniform length.

Should it be desired, bands of unclipped nap may be left for the brim or at other points upon the hat-body by closing the air-opening into the casing or by removing the wiperarms or cutter at the desired points, and such bands will be sharply delined and at their edges will be separated from the clipped surface by clear and perfectly-straight lines. in consequence of the curved form of the ends of the bearingbar, cutter, and wiper-arms, the apex of the cone of the hat-body is as evenly and perfectly clipped as is any part of the surface, by which means the usual hand-clipping at such point is avoided, and the finished hat is caused to present a smooth and uniformlytinished surface over its entire exterior.

The hat-body is held in position upon and fed around the bar Iby means of the followingdescribed mechanism: Journaled within suitable bearings in rear of the barI are four rollers, which are arranged in pairs, and one pair, 0, placed below and one pair, 0, above the point of said bar, the centers of each pair being in the plane occupied by that portion of the hat-body with which they are to engage. The rollers O and O are made tapering, and are arranged upon lines nearly radial to the rounded end of the bar I, the variation from such lines being just sul'licient to cause each pair to produce in the hat-body a tendency to draw down firmly upon said rounded end. In order that the fabric may be kept taut over said bar, the lower rollers, O, are either made larger than the upper rollers, O, or are caused to rotate with greater speed, it being only necessary that the peripheries of said lower rollers should have the greatest velocity in order to secure the desired result. The feedrollers 0 and O of each pair are geared together, and the pairs are connected by means of an intermediate gear-wheel, I, by which arrangement they are caused to move simultaneously. A belt-wheel, Q, secured upon the projecting shaft of one of said rollers, and connected by means of a belt, q, with a pulley, 0, upon the shaft E, enables said rollers to be driven by the rotation of said shaft.

Any desired means may be employed for raising the feed-rollers and bearing-bar when necessary to place in or remove from position a hat-body; but we preferably make use of two cords or wires, It, which extend from a footbar, a, upward over suitable fixed hearings or pulleys, S, and have their ends connected with the outer end of said bearing-bar, the arrangement being such that if said foot-bar is depressed said bearing-bar and feed-rollers will position.

be raised, while by releasing said foot-bar from pressure said parts will return to their normal If desired, the weight of said rollers and bearing-bar may be wholly or partially counterbalanced by means of weights'T, suspended from said cords R.

The wiper (J is preferably constructed from cast-iron, and is found to possess great durability and its arms a to maintain sharp, clean edges when brought into contact with the cutter I. In consequence of the open form of said Wiper, the least practicable obstruction to the passage of air is offered, and the operation of the exhaust-fan is not interfered with to any appreciable degree.

While the mechanism described for holding and feeding forward the hat-body is preferably employed, other means for effecting the same result may be used, if desired.

In Fig. 2 is shown acone, .U, which has such size and shape as to enable it to receive any usual size of hat-body, and has its apex rounded to correspond to the curvature of the ends of the iper-arms cand cutter 1. The cone U is secured upon a shaft, which is suitably journaled upon the frame of the machine, and is driven from the shaft E, as in case of the rollers O and O. The hat-body is held in place upon said cone by projecting pins or by any similar means.

Having thus fully set forth the nature and merits of our invention, what we claim as new 1s- 1. The method of clipping hat-bodies or other articles having a pile or nap surface by causing the heirs to be drawn outward into a position having a right angle to the body of the fabric, and cutting or clipping the ends of said hairs while in such position, substantially as specified.

2. The method of clipping hat-bodies or other articles having a pile or nap surface, so as to form or leave belts or bands of unclipped or raised hairs, by removing portions of the Wiperarms or cutter or interposing solid portions of the casing between the same and the material being operated upon, substantially as and for the purpose shown.

3. The clipping mechanism described, consisting of the wiper 0, having radial spiral arms 0, which are each constructed with an outwardly-curved end, in combination with the stationary cutter I, that corresponds in shape to the form of said wiper-arms, and with mechanism for rotating said wiper, substantially as and for the purpose set forth.

4. In combination with the clipping mechanism described, the mechanism substantially as shown, whereby a current of air is caused to pass from the fabric being operated upon toward said clipping mechanism, substantially as and for the purpose specified.

'5. In combination with the clipping mechanism described, the V-shaped bar M, arranged in front of the cutter I, and having its rounded edge conformed to the line of the edge of said cutter, substantially as and for the purpose shown.

6. In combination with the holding-bar M, the rollers 0 and 0', arranged as described, and adapted to move a hat-body around said bar, substantially as and for the purpose setforth.

7. In combination with the holding-bar M,

having a rounded edge, the rollers O and 0,

latter as to cause said hat-body to be drawn closely upon and held against the rounded end of said bar, substantially as and for the purpose specified.

9. In a hat-clipping machine, cutting mechanism, substantially as described, which is adapted to operate simultaneously upon a line extending from the brim of the hat-bodyaroun'd the center or apex of the same, substantially as and for the purpose shown.

10. In combination with the bar M and with mechanismfor moving a hat-body continuously around the same, the comb N, arranged to engage with the outer surface of such hatbody immediately above said bar, substantially as and for the purpose set forth.

11. In combination with the wiper (3, provided wit-h radial arms 0, that have each an outwardly-curved end, and with the stationary cutter I, which has a correspondiugly-curved end,means,substantiallyasdescribed,whereby said wiper may be adjusted longitudinally and toward said cutter, substantially as and for the purpose shown.

12. The hereinbefore-described machine, in which the clipping, nap-raising, holding, and feeding mechanisms are constructed and combined to operate in the manner and for the purpose substantially as specified.

In testimony that we claim the foregoing we have hereunto set our hands.
