SPECIFICATION forming part of Letters Patent No. 401,054, dated April 9, 1889.

Serial No. 220,978. (No model.)

The object of my invention is to provide a i new and improved lace-paper machine which is simple and durable in construction and very effective in operation.

The invention consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement with parts broken out. Fig. 2 is arear side elevation of the same with parts broken out and parts in section. Fig. 3 is a sectional end elevation of the samewith one of the large wheels removed. Fig. 4 is a plan view of the paper-roll fastener. Fig. 5 is a side elevation of the paper-cutting device. Fig. 6 is a plan view of the scraping device. Fig. 7 is a bottom view of the box carrying the scrapers. Fig. 8 is a sectional elevation of part of the Wood drum, and Fig. 9 is a sectional end elevation of the device for adjusting the wooddrum shaft. Fig. 10 is a detail sectional view of Fig. 7.

On a suitable frame, A, is mounted the main shaft B, provided with the usual fly-wheel and driving-pulley, B, or other means for imparting a rotary motion to the said main shaft B. A pinion, O, secured on the said shaft B, meshes into the gear-wheel 0, attached to the shaft D, mounted in suitable bearings on the frame A, and carrying the wheel or roller D, provided with the lace-pattern to be impressed into the paper." The gear-wheel D on the said shaft D meshes into the gear-wheel D secured to the shaft D mounted in the bearings D adapted to be adjusted in guideways formed in the frame A by a screw, D or other means.

The shaft D carries the leather roller E, held in close contact on top of the pattern wheel or roller D, and on each side of the latter is placed alarger removable or adjustable wheel, F, also held in frictional contact with the said pattern-roller D, and provided with a Wooden rim, F, made in sections, each having on each side of its base a dovetail fitting into a corresponding dovetail formed on the sections F of the said wheel. The sections F are mounted on a shaft, F", held in bearings or boxes F each fitting into an inclined slot, F formed by the frame A and by a hinged cover, F, provided with a screw, F screwing against the said hearing or box F The pivoted end of the cover F is fastened in any suitable manner by pins or bolts to the frame A. The screw F serves to screw the wheel F up against the pattern-wheel D. The hinged cover F permits of removing the wheel from the said frame A, and the sectional wheel permits of changing the width of the wooden rim to suit the width of the paper to be treated.

On the periphery of the wooden rim of each wheel F operates a scraping device consisting of the frame G, hinged by one end on the frame A, and provided on its other end with bolts G the upper threaded ends. of which pass through lugs A, formed on the sides of the said frame A. On the upper ends of the said bolts screw the nuts G which serve to raise or lower the said frame G. On the latter is pivoted the box or frame G containing the scrapers or files G which are vertically adjustable by means of set-screws G, screwing through the bottom of the said box G which is held in place by the set-screws G The scrapers or files are placed across the rims of the wheels F at angles to the axes of the said wheels, as shown in Fig. 6.

The shaft D is provided with a sprocket- Wheel, H, over which passes a sprocket-chain, H, also passing over the sprocket-Wheel H secured to the shaft H mounted in suitable hearings on the frame A, and carrying a roller, H, over which passes an endless belt, H also passing over the roller H, having its bearings in a bracket on the front end of the beam A of the frame A. A tension-roller, I, mounted in an arm, I, hinged on the frame A, acts on the upper part of the endless belt H The gear-wheel D also meshes into the gear-wheel J, mounted on a stud extending from the said frame A, and provided with a cam-arm, .l, which operates at every revolution of the said gear-wheel J on a lever, J fulerumed on an arm, J, adjustable on the frame A. This lever J operates the cutting mechanism K (shown in detail in Fig. 5) by means of a link or rod, J. The latter is pivotally connected with the said lever J and with the toggle-joint K, connected with the shears K pivoted together, one of which is secured on a cross-beam, A, on the front of the beam A of the frame A.

On the beam A are held a number of shafts, L, carrying .rolls of paper N, held on cone-shaped supports L, adjustable on the said shafts L. On one end of each of the said shaft-s L operates a spring, U, and on the other end of each shaft is a tension device, 0, consisting of a weighted lever, O, pivoted on the beam A and provided with a band, 0 which passes over a pulley, L secured on the said shaft L.

In front of each shaft L is arranged on, the beams A a roller, P, and between the said shafts L is erected a standard, Q, provided with a box, V, consisting of the sides V, and the bottom consisting of two pieces, V inclining toward each other and having a central slit, through which passes the paper. Each box is tilled with soapstone-powder, so that the paper on passing through the box is coated on both sides with the soapstone-powder. Above each box is a roller, Q, over which passes the paper from its respective roll. From the rear ends of the beam A extends downward a box, R, provided with a series of rollers, B. On the frame A is mounted a roller, S, provided with loose flanges S, adj ustable on the said roller S to suit the width of the paper to be treated. A short distance above the pattern-wheel D is arranged a cross-bar, '1, over which passes the paper before it enters upon thepattern-wheel.

The shaft F can be adjusted lengthwise by the screw l, screwing through the journal of the shaft and against the end of the same. The screw U is provided with a hand-wheel, U, and with a jam-nut, U for holding the screw U in place after being adjusted, as shown in Fig. 9.

The operation is as follows: The rotary motion of the main shaft B is imparted to the pattern-roller D and its leather roller E by means of the gear-wheels C G and D D. The wheels F are rotated by being in frietional contact with the pattern-wheel D. The paper from the rolls N is drawn through the machine by being passed between the rollers F, the pattern-wheel D, and the leather roller E, and, according to the capacity of the machine, the respective number of paper strips from the rollers N pass simultaneously and one on top of the other over the roller S and the rod T, upon and around the pattern-wheel D, and the paper is pressed upon the projections forming the pattern by the wooden rims F of the wheels F, located one on each side of the said pattern-wheel D. The paper strips are roughly pressed against the pattern-wheel by the said wheels F, and the final finishing is given to the paper by the elastic roller or wheel E, located on top of the pattern-wheel. The wooden-rimmed wheels which, for some patterns, are made of a hard woodsueh as maple-and for some other patterns are made of a softer wood such as white woodpermit of the embedment therein of the raised ligures of the pattern-roller with the interposed paper, and thus effect the sinking of the impression in the paper. These wheels are intended for cutting only and the leather roller for embossing. The elastic surface of the wheel F. also presses the paper softly upon the pattern-wheel, thus avoiding all unevenness in completing the impression. The impressed paper is then passed to the endless belt ll, and is delivered by the same to the cutting apparatus K, which cuts the strips of paper into equal lengths. The length of the cut paper strips is regulated by the differential speed of the gear-wheels l) and .T, and by changing the diameter of the latter wheel I am enabled to increase or diminish the length of the paper to be cut.

It will be seen that each wheel F can be easily and quickly moved from the main frame A by raising the cover F'", as shown at the right of Fig. 2, so as to replace the wooden rims F in case they are worn out by their contact with the pattern on the pattern-wheel D. This replacing of the wooden rims is easily accomplished by unscrewing the bolts holding the sections F together, and the latter being then slightly moved apart permit of removing the dovetailed sections of the wooden rim. The wooden rims of the wheels are kept as smooth as possible by the files Gr acting on the peripheries of the said rims. The frictional contact of the wheels F with the pattern-wheel D can be regulatedthat is, increased or diminished-by screwing on the rods F and the contact of the leather roller or wheel E with the pattern-wheel D can be adjusted by the screw 1). Any desired pattern can be placed on the shaft D and impressed into the paper.

The soapstone-powder permits of taking the cut strips of paper apart easily.

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a lace-paper machine, the combination of a pattern-wheel with two wheels having wooden rims, means, as described, for holding the said wheels in frictional contact with the said pattern-wheel, and a roller having an elastic rim and held on top of the said pattern-wheel, substantially as shown and described.
