MACHINERY. FOR THE MANUFACTURE OF INLAID LINOLEUM.

SJEEGIFICATION forming part of Letters Patent N 0. 697,551, dated April 15, 1902. Application filed May 1, 1901. Serial No. 58,281. (No modeL) To aZZ whom, it may concern:

Be it known that I, CHARLES HERBERT SCOTT, a subject of the King of Great Britain and Ireland, residing at Gloucester, in the county of Gloucester, England, have invented Improvements in the Manufacture of Inlaid Linoleum and in Machinery or Apparatus Therefor, of which the following is a specification.

This invention relates to the manufacture of inlaid linoleum, particularly that of the kind in which the pattern or design consists of small figures-for instance, squares of different colors and arranged so as to produce the required effectand to machinery or apparatus for use in such manufacture.

According to this invention a mixture of loose granulated linoleum is compressed during passage through a die into pieces of the required size and shape, which pieces as they are discharged from the die are pressed onto a canvas or other backing, and for the purpose of enabling a great variety of patterns or designs to be produced at small expense the action of devices designed to efiect the distribution from the supply-hoppers of the granulated linoleum of which the pattern is to be formed is regulated or controlled by pin or tap'pet drums, bands, or the like, or by drums, bands, or the like formed with perforations or slots, the pins or tappets or the like or the perforations or slots or the like being arranged or disposed according to the pattern or design to be produced, the drums, bands, or the like being capable of being changed or shifted when it is desired to alter the pattern or design produced, and the arrangement being such that only such material as is required for forming the pattern or design will be distributed from the supplyhoppers.

Machinery or apparatus according to this invention may be variously modified.

The accompanying-"drawings illustrate, by way of example, one arrangement of machine, Figure 1 being a longitudinal section, Fig. 2 an end view of the lower part of same, and Figs. 3, 4, and 5 are detail views hereinafter referred to. I

In the frame 1 of the machine are mounted a pair of shafts 2 2, each carryinga drum 3.

' Around these drums passes an endless band 4, that serves to support the canvas backing 5, onto which the pieces of linoleum are pressed. The shaft 2 has fixed to it a ratchetwheel 6, which has a step-by-step motion imparted to it by a pawl 7, which is carried by an arm 8, turning about the shaft 2 and linked to a lever 9, carrying an abutment or roller 10,

' The upper part of each die-plate 13 is formed with a number of grooves or channels 14, which are of slightlyless width than the squares or other figures in the pattern and may conveniently be horizontal. Above each die-plate is a hopper 15, adapted to contain granulated linoleum and to deliver the same to the several grooves or channels in the dieplate at or about the middle of their length. The grooves are toward one end covered by a heated plate 16. The plate may be made with a passage 16, through which steam or hot air is passed or in which gasburners may be arranged. Each groove or channel 14; is fitted with a plunger 17, retained in position by a cover-plate 18, common to the set of grooves.

' In connection with each die-plate 13 a trans verse bar. 19 is arranged so as to be capable of a parallel to-and-fro movement along the frame of the machine. The movement of this bar may conveniently be obtained by connecting it by links 20 to a lever or levers 21, which is or are oscillated by a cam or cams 22 on the main shaft 12. The front edge of the bar 19 extends beneath the projecting ends of the plungers 17, each of which is formed with a downwardly-extendinglug or hook 17 adapted to engage with a shallow flange or lip 19, formed along the front of the transverse bar, the arrangement being such that during the backward movement of the bar 19 any plunger engaged by such lip will be drawn back therewith. The rear portion 19 of said bar is extend ed upwardly and carries or has pivoted or hinged to it a series of abutmentpieces 23, one of which is opposite to each plunger. When these abutment-pieces are in their operative positions and the transverse bar 19 is moved to and fro, their respective plungers will also be moved to and fro and will at each inward stroke discharge from the grooves orchannels 14 certain quantitles of linoleum mixture, while at each outward stroke fresh supplies of mixture will drop from the hoppers 15 into the grooves or channels 14. When the abutment-pieces 23 are raised into their inoperative positions, the plungers will be left at the ends of their outward strokes and no mixture will be discharged from their grooves.

For the purpose of bringing the several abutment-pieces 23 into or keeping them out of action during the forward stroke of the transverse abutment-bar 19 in the order necessary for the production of the required pattern or design each abutment-piece 23 is connected, by means of a link or rod 24, to one end of a lever 25, the other end of which has a metal pin or point 26 working againsta pattern-drum 27, formed of or covered with sheet metal or other substance having perforations, slots, or holes 28, Fig. 5, punched through it. This drum has an intermittent rotary motion imparted to it from the main or cam shaft 12 of the machine at those periods when the transverse abutment-bar19 is at rest in its rear position. In the example illustrated it is shown driven by belt-gearing from the shaft 2. Just before the drum is moved a kickerbar 29, extending across beneath all the levers 25, actuates them in such wise as to free their points 26 from the perforations, slots, or holes 28in the pattern-drum, the kickerbar 29 again moving after the drum has moved so as to allow the points 26 of the respective levers to rest on the surface of the pattern-drum and so hold their abutmentpieces out of action or to enter the perforation, holes, or slots and allow their abutmentpieces to come into action, according to the pattern to be produced. Across the front end of the grooves there is formed through the die-plate 13 a slot 30, which serves as a delivery, whence the linoleum mixture discharged from the grooves or channels 14 is deposited onto the canvas backing 5, passing beneath it. \Vithin this slot is fitted a pressure plate or plates 31, which is or are reciprocated vertically by means of bell-crank le vers 32, to which it or they is or are connected and which are linked to a lever 33, oscillated by a cam or cams on the main or cam shaft 12. The pressure plate or plates is or are arranged and actuated so that during a portion of the forward stroke of the abutment-bar 19 they close the outlet ends of the grooves or channels 14, is or are then raised, so as to allow of the mixture being discharged from the said grooves or channels into the deliveryslot 30, and is or are then moved down again, so as to force out the mixture onto the canvas backingbeneath. The delivery-slot may be continuous for the whole width of the machine; but it can be divided into vertical grooves, the number of which corresponds to or is a multiple of the number of grooves or channels 11 in the die-plate. The thickness or width of the delivery-slot and pressure plate or plates is slightly less than the length of the squares or other figures forming the pattern.

Each supply -hopper is provided with a shaking-bar 34,with arms 35, adapted to shake the loose granulated linoleum into the grooves or channels in the die-plates.

The action of the machine is as follows: Assuming that all the plungers 17 are in their outermost positions, the action of the shakers 35 causes the horizontal grooves or channels 14 in the die-plate to be charged with granulated linoleum. The abutment-bar 19 now travels forward and with it such of the plungers 17 as have their abutment-pieces 23 in the operative orlower position, which plungers compress the linoleum into those portions of the grooves or channels 1 1 in the die-plate which are beneath the heated plate 16, the pressure plate or plates 31 preventing for the time being the discharge of the linoleum from said grooves or channels. The forward movement of the abutment-bar 19 then ceases and the pressure plate or plates 31 is orare lifted, leaving the ends of the grooves or channels 14 open, whereupon the abutment-bar advances, pushing the compressed linoleum out of the grooves into the delivery-slot 30 and beneath the pressure plate or plates, which then descends or descend rapidly and pushes or push the compressed pieces of linoleum out of the delivery-slot onto the canvas backing 5 below. The abutment-bar 19 then travels back, the flange or lip 19 along its front edge engaging with and drawing back the plungers 17 to their original position, the kicker-bar 29 lifts all the points 26 clear of the patterndrum 27, whereupon the pattern -drum is partly rotated, so as to present a fresh row or series of perforations, holes, orslots 28 to the levers. This operation is repeated, the canvas backing 5 moving forward step by step and the plungers 17, which are moved forward at each forward stroke of the abutmentbar 19, being varied in accordance with the varied disposition of the perforations, holes, or slots in that part of the drum which is for the time presented to the abutment-levers. Whenever a perforation, hole, or slot 28 in the drum 27 comes opposite the point 26 of the lever 25 of a given abutment-piece 23, that particular piece will drop into its operative position and the corresponding plunger 17 will travel forward and push a compressed piece of linoleum under the pressure-plate 31, which deposits it onto the canvas backing.

The patterns can be changed by changing the perforated sheet-metal covering of the drum or by changing the drum itself.

The canvas backing may, in some cases, be

5 forth. 2. In apparatus for the manufacture of incaused to travelcontinuonsly at such a speed 5 traveling in a horizontal, vertical, or other convenient direction can be used. Also the drums, sheets, or the like may be provided with pins, knobs, or tappets adapted to bring the plungers into action or hold them out of action.

As will be understood, there may be any desired number of grooved or channeled dieplates with appurtenances, each being pro' vided with a hopper for containing a different-colored linoleum, the number or variety of patterns or designs which the machine can produce varying accordingly. The several die-plates are fixed one behind the other upon the machine, and the several abutmentbars are connected together by links 36 and operated simultaneously.

In some cases some or each of the hoppers may be divided into compartments, each of which can be charged with a different-colored linoleum.
