HENRY MICHAEL STEINTHAL, OF SCARBOROUGH, COUNTY OF YORK, ENGLAND.

MACHINE FOR THE MANUFACTURE OF FLOOR-CLOTHS, 80C.

SPECIFICATION forming part of Letters Patent N 0. 420,634, dated February 4, 1890.

Application filed July 5, 1889.

To all whom it may concern.-

Be it known that I, HENRY MICHAEL STEIN- THAL, floor-cloth manufacturer, a subject of the Queen of Great Britain, residing at Scarborough, in the county of York, England, have invented certain new and useful Improvements in Machines for the Manufacture of Floor-Cloths, &c., ofwhioh the following is a specification.

My invention consists of a machine for pressing materials which are in continuous or long lengths, and it is constructed so as to bring strong direct downward pressure upon successive sections of the material during intermittences in the onward movement or travel of the latter. The machine has been specially designed for pressing sheets or facture of floor-cloths, wall-coverings, or for other like purposes, the said sheets or pieces being arranged in any required order as to color upon a length of cloth; but it is applicable in other cases where continuous or long lengths of material have to be pressed.

My machine consists, essentially, of, first, a rising and falling plunger or presser; second, a fixed table or block against which the pressing is effected; third, mechanism whereby the material to be pressed is moved forward intermittently between the plunger and the table, each movement being equal to the width of the pressing-face of the plunger; and, fourth, a steam-heated cylinder, over which the material is led before reaching the plunger. This cylinder will, however, only be required in cases where the material has to be warmed or softened before pressure.

Having explained the nature and main features of my machine, I will describe more in detail how it can be constructed, and for this purpose I Will 'refer to the accompanying drawings,whicl1 represent a pressing-machine in which my invention is embodied.

In the drawings, Figure I is a side elevation of the machine. Figs. 2 and 3 are respectively an end elevation and a plan, and are drawn to a somewhat larger scale than Fig. 1. The steam -heated cylinder and the roller from which the roll of cloth is unwound are omitted from these two figures.

Serial No. 316,597. (No model.)

a is a fixed table or pressing-block, above which is arranged a plunger or presser'b, having an up-and-down movement. This movement can be produced in any convenient manner. The preferred arrangement is that shown in the figures, and consists of eccentries c c on a rotating shaft d, communicating motion through links 6 e to cross-heads f f, which are connected by vertical bars to the plunger Z). Four vertical bars (marked, respectively, g gg and 9 are shown in the figures, and all of them may connect the crossheads f f to the plunger; but in the arrangement shown the three bars marked 9 g g constitute this connection, while the fourth bar g is a fixture to the frame of the machine for the purpose hereinafterdesoribed; but it also serves as a guide to the cross-head and plunger in their up and down movements.

At one side of the press is a steam-heated cylinder h, over which the material A to be pressed-say a roll or length of cloth covered with sheets or pieces of paint compositionis led from a rolleri or otherwise. From the steam-heated cylinder h the clothis led between the plunger Z), and the pressing-block a and its end, or the end of a sheet or cloth connected thereto for the'purpose, is attached to a traveling band j, arranged at the delivery side of the pressing mechanism, which draws it forward intermittently, as about to be described.

Y Upon a Wheel 70, which is on the shaft (1, (though itmight be on another shaft,) is a crank-pin l, connected by a rod m to an arm 11-, mounted loosely on the shaft of a ratchetwheel 7', on which shaft is a pulley 19, that drives the traveling bandj. This arm n has a pawl q, which takes into the ratchet-wheel r. The result of this arrangement is that, as the crank-pin l in the revolution of the wheel 70 is approaching the wheel 1", it causes the arm n to push the ratchet-wheel 7' round by means of its pawl q. Consequently the travel-' ing band j, and therefore the length of paintcovered cloth, are caused to move a certain I distance that is to say, a distance equal to the width of the plunger 1). During this forward movement of the cloth the plunger is clear of the bed or pressing-block a. Then as the crank-pin Z in the revolution of the wheel 7.; is receding or moving away from the pulley p the arm n and pawl q are drawn back, the pawl riding over the ratchet-teeth 0'. Therefore there is no movement of the cloth, and it is during this interval or intermittenee of the movement that the plunger-l) comes down and presses that part of the material which is then below it. This intermittent action continues until the whole length of the cloth or material has been pressed in successive sections. The traveling band j should be as long as the roll or length of material to be pressed, which, in the case of floorcloths, is generally sixty feet. It is preferred not to carry the traveling band j round a roller on the shaft of the ratchet-wheel 0, but round a roller driven by a belt from the pulley p on that shaft, as ShOWll,8 being the roller driven by a belt t and pulley u from the pulley p.

s is 'the roller at the other end of the course of the traveling band 3'.

'v is the driving-shaft of the machine. Motion is transmitted therefrom by a pinion 11.1, which gears with internal teeth out around the wheel 76. In order to allow of the pressure being regulated, the machine is fitted with a screw-shaft :0, having a handle y and gearing with screw or worm wheels on the vertical bars g. By turning the shaft x rotation is given to the vertical bars 9, which are screw-threaded at one part to take into corresponding female threads in the plunger 1). The height of the plunger, and consequently the pressure exerted thereby, is regulated.

If itis required to emboss the material, the plunger will be engraved or'cut accordingly.

In order that the machine may always indicate the pressure to which it is adjusted, I adopt the following contrivance: Upon the plunger b,I fix a curved bar 1, divided off to indicate on an enlarged scale parts (say hundredths) of an inch, assuming an inch to be the maximum movement of the plunger. To a piece 2, screwed or firmly attached to the top of the bar 9 which is a fixture to the frame of the machine, I attach the short arm of a lever 3, pivoted at l to a bracket, forming part of the plunger. The long arm of the lever 3 is connected by a link 5 to a hand or indicator 6, which is pivoted at its end to a bracket forming part of the plunger, the connection between the link and the indicator being near the pivot. The result of this arrangement is that as the plunger moves up or down, while the bar 9* remains stationary, the extent of the movement is multiplied by the lever 3, link 5, and indicator 6, and is indicated 011 the curved bar or scale 1, where it can be easily read.

Vhat I claim, and desire to secure by Letters Patent, is-

1. A machine for the manufacture of floorcloths from materials in continuous or long lengths upon which plastic compositions are primarily placed, said machine comprising a fixed table or block a risin and fallin 7 O 0 presser or plunger adapted thereto, intermittentlyacting mechanism which moves said material forward intermittently between said plunger and table, and a steam-heated cylinder for warming or softening the plastic compositions, said cylinder being arranged to be traversed by the material before it passes between said plunger and table, substantially as set forth.
