: Application filed September My invention consists of an improved machine for ornamenting or brocading leather,

andhas for its particular object, the brocading of ooze or' suede leather. j

In the accompanying drawing illustrating my invention Fig. 1 is a plan view of my ma- "cylinder having the ornamental pattern or design to be reproduced, formed on the 'pe -riphery of the roll,,combined with other structural features to adapt ,it'to practical use. ,7 I 7 Referring to the. drawing, 6. is theframe of the machine supporting suitable bearlngs in which are mounted the paper roll.7, the brocading cylinder 8, the pressure roll 9, the

"brush roll 10, the feed roll 11, and the carding roll 12. Thepaper'roll 7 'is'adapted to carry asheet of paper 18, which paper has an adhesive coating over the surface which is presented in contact with the suede side of the leather while it is subjected to the action of the .brocading cylinder. 'The adhesive coating of the paper 1-3 consists of any suitable gum, such for instance as shellac and alcohol preferably with the addition 'of'some softer gum thinly and uniformly spread upon the paper and dried, and containing, if dev V the hide or skin between them, as other .fa-

- sired, some coloring matter or dye. V

I have discovered that thesuede side of leather will permanently retain av pattern transferred by a heated brocading roll through a gummed paper, and lfthe gu'mmed paper is colored, a correspondingly colored pattern is. permanently transferred thereby.

The gummed substance in the paper is driven into the texture of the leather at the points "of immediate contact of the'p'atternwiththe becomes indelibly impressed therein.

leather and thereby the pattern is more clear-' ly defined and permanently sealed than when no'gummed substance '15 used. Furthermore whena colored pattern is required, the gum, acts as an efficient conveyor'of the. coloring matter into the texture of'the leather andlit Tie bestresults are produced by; employing a pressure roll with the brocad ng roll; The

and the gum has no opportunity to spread, and blur the pattern, which would be the tenor platen were: used insteadofa roll,

' 'The paper roll'7 is mounted, asv shown supports at the top of the frame of the machine, and the sheetof paper 13 is fed] downwardly therefromand underfthe brocading cylinder 8, together with the'leather,

the paper lying between the surfaceof the 3 f and the'upper or suede b'rocading. cylinder 8 side of the leather. The brocading cylinder 8 is mounted in vertically and yieldingly. adjustable.; bear-.-

ings l t for the purpose of varying thespace between the brocadingfcylinder 8 and the pressure jroll 9,150 as toadapt'it. to different thicknesses of leather and-forth'e purposeof regulating the degree of pressure ofthe pattern or design uponthe surface ofthe leather,

and to compensate for variationsin the thickness of a. given hide/or skin;;-

.I have shown as one form of means foryer tically and yieldingly adjusting the pressure 1 of thebrocading. cylinder 8 the adjusting screw 15, and the helical spring lfi interposed between the bearings 14 of the brocading cylinder 8 and the cap 31 secured totheend of" the adjusting screw 15. Both bearings of the brocading cylinder'8 are provided with similar vertically and yieldingly adjusting means.

My invention is not limited to the specific means shown for adjusting the space between the broca'din'g cylinder 8' and the pressure roll 9, and for regulating the. pressure upon miliar and-well known m-eansof accomplishing such adj u stment would be the equivalent of the combination shown. It is-obvious also! that the arrangement may. be reversed by mounting thejbrocading cylinderki'n' fixed:

adjustable bearings...

Upon, the peripheral surfaceof the bro-v cading cylinder ,8 is formed or cut or arranged.

in any suitable manner the pattern or design to be reproduced upon the leather,v and. the pattern is of the cameotype, preferably cut about three-sixteenths of an inch deep. The

depthof thepa-tternfmaybe varied to meet the special requirements in producing different designs, and also to adaptit to the character and. weightof the leather -to .be br-o V Beneath the'brocading sub sure roll 9 is mountedin iiXed bearings 32 in the frame of themachine, and between which and the brocading cylinder 8, the hide or skin 17 and the sheet of paper 13 are carried and the design upon the leather.

An important feature of my invention consists in constructing thepressure roll of less diameter than the brocading roll when the axes on which they are mounted are rotated atthe same speed. -The object being to have I the surface of the pressure rolltravel at slightly less speed than the speed of the surfac'e'of the Y that by having the pressure roll of less d1 alnebrocading roll. I have discovered ter than the brocading roll by approximately the thickness ofthe material to be brocaded, a much, clearer and more pronounced and permanent pattern is produced upon the material. I

The tendency of this difieren'ce the speed of the. surface of the brocading cylinder and thepressure rollis slightly to retard. the

I forward movement of thematerial. .Any

meansof adjusting the speed of the surface of roll slightly less than that of the pressure p the surface of the brocading rollto about the extent above described would be within the scope of my invention.

I have made application for United States 'Letters Patent jointly with James Y; Lake for a'machine f or ornamentin'g leather, Serial-Number 682,382, filedDecember 24, 1923, which is substantially the same as the ma- 1 chine herein described, excepting thatin the machine of the pending applicationthe sur- [faces offthe brocading and pressure rolls travel atthe same speed.

on the front of the inachineis a table 18 over which the hide or skin 17 is laid and from which it is fed between and by the feed roll 11, and the brush roll 10 to the brocading cylinder '8 and pressure roll 9v as and for the purpose above described.

Thebrush roll 10 is useful in removing any dirt and foreign matter from the suede sur face of the leather, so that itjmaybe presentfed to. the action of the brocading cylinder 8 to: the best advantagefor receiving the impression of thepattern ordesign. The brush roll 10 is what its name indicates,a roll havingvits periphery set-with-bristles of suitable roll 9.- I v 7 At the rear ofthe brocadingcylinder 8, and

length and stiffness-t0 adequately clean the surface of the hideor skin, and'to'cooperate.

with the feed roll 11 in presenting the-hide or skin to the brocading cylinder '8 and pressure in contact with it, ismou'nted in suitable fixed bearings intheframe of the machine,thecarding roll 12.

The periphery ofithe carding roll 12 is cove I eredwith the well known wire cardicloth com monly used in carding wool and othertextiles. The carding r0ll'12 is-rotated by means of ected to the required pressure to produce 19, held in yielding contact'with the pressure roll 9, by means of the adjustable bracket 20 secured to the frame of the machine, I -For the purpose of raising the'brocading cylinder 8, so as to insert the hide or skin and the sheet of paper 13 beneath it, or for any' other purpose temporarily to increase'the space between it and the pressure roll 9, I

have-provided a treadle connected by suit able vertical rods 33 with the levers 34: pivot- 7 ed to the frame of the machine at35, the le-' vers 34 being pivoted to the rod 36, Whichin turn is connected with thebearings 14 of the brocading roll 8. 1

The brocading cylinder 8 is, hollow and preferably is heated electrically by means of resistance coils installed within the cylinder.

The resistance coils are'preferably contained in a plurality of glass tubes 37 and are connected with a source ofpower through the wires 39 and the brush 38 forming a contact in any of the well known ways. The brocadmg cylinder Sinay, however, be heated by a gas or oil flame or by steam or any other suitable source of heat. The brocading cylinder 8, and of cou'rse the pattern upon it, should-ordinarily be heated to a temperature of from about two hundred to two-hundred fifty degrees Fahrenheit during the operation" This, however, must depend of the machine. upon certain varying conditions, namely, the

thickness of the skin to be ornamented, the kind of dye used and the speed of operation of the machine, which the operator must take into consideration in regulating the tempera ture'of the roll. 1

Mounted upon the shaft of the roll 9 is the driving pulley of the machine driven by abelt from anysuitablesource'of power. Thegear 21 (see Fig. 3) on the shaft of the pressure roll .9, drives thegear 22'on the shaft of'the brocading cylinder 8, which in t urn', through the intermediate gear 23, drives the gear 2 on the shaft of the "brush roll 10,the gear-2d meshing with gear- 25'.

on the shaft of the feed roll 11, by which the latter is driven. a The carding roll 12 is driven by the gears 27and 21. v r

The brush roll10 is also mounted in vertically and yielding'ly adjustablebearings, .the

the gear 26'mounted on itsshaft, and by pressure I adjusting means consisting of the adjusting screws 28,and the helical springs 29- confined between the bearings 40 of the brush roll'10 and the plate 41 secured to the adjusting screws28.

The operation of the machine is as follows: v

The brocading cylinder having attained the requisite degree of heat, as above de-V scribed, a hide or skin is laid upon the table 18 with itssuede side upward, and is presented to the feed roll 11, which delivers it between the broc'ading cylinder 8 and the pressure roll 9. Simultaneously the sheet of gummed and colored paper 13'is presented to the brocading cylinder 8, as shown in the drawing (Fig. 5), above and in contact with the suede side of the hide or skin, the sheet of paper 13 and the hide or skin being fed together between the bro'cadin cylinder 8 and pressure roll 9, under sufficient pressure to transfer the design of the pattern on the brocading cylinder 8 to the surface of the hide or skin. By reason of the pressure of the pattern upon the paper and the heat of the roll, the hide or skin will receive and permanently retain not only the figure of the pat-- term-but the color of the guinined surface of the sheet 18, so that by these means an accurate reproduction of any pattern or design in form and color may be obtained upon the ooze or suede side of the leather.

7 The chiefnovelty of this invention over the machine described in said pending application, consists of the pressure roll being of less diameter than the pattern roll.

' My machine, by suitable adjustment of the pattern and pressure rolls, may be used for to travel at slightly greater speed than the V periphery of the other roll.
