Y H. D. B. LEFFERTS; Cloth-Stretching Machine.
N4 PETERS, PHOTO-LITHOGRAPHR, WASHINGTON. [1GV UNITED STATES PATENT OFFICE..
HENRY D. B.` LEFFERTS, OF NEW BRUNSWICK, NEW JERSEY, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO EDWIN GULLIOK.
CLOTH-STRETCHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 231,881, dated August 31, 1880. Application filed January 10, 1880.
To all whom 'it may concern:
Be it known that I, HENRY D. BLEEFEETS, of New Brunswick, in the county of MiddleseX, and inthe State of New Jersey, have iu vented certain new and useful Improvements in Cloth-Stretching Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the Io letters ot' reference marked thereon, making a part of this specifica-tion.
The nature of my invention consists in the construction and arrangement ot' a machine for stretching cloths and cassimeres after they I5 have been printed and shrunkenffor the purpose of bringing them back to their original length, as will be hereinafter more fully described, and set forth in the claims.
In order to enable others skilled in the art 2o to which myinvention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure l is a perspective view of my machine. Fig. 2 is a cross-section of one of' the rollers. v
A represents the frame ot the machine, the four upright corner-posts ot' which are slotted vertically from their upper ends downward for 3o a suitable distance, as shown ata/fm. The corner-posts at each end ot' the machine are connected by a crossbar, B, and in the bottom of Vthe slots w are placed the journals ot' a roller, O. Abovd this roller is placed another roller,
3 5 G', the journals of which also project through the slots m, and have bearings or boxes a placed above them.
D is a tension-bar having its ends placed on top of the boxes a, in the slots x, and a 4o screw, E, screwed through the cross-bar holds said tensionbar down, so as to create more or less pressure of the roller C on the roller U, as required.
F F are door-rollers, and G a ceiling-roller,
around which the cloth is passed in the manner shown in the drawings.
The rollers C and C are all made alike, each roller being made of a wooden cylinder, b, covered with cloth d, and then an additional the rollers auniform motion when the machine 6o is in operation.
By the application of the rubber-covered rollers I secure a perfectly even tension on the cloth, which tension may be regulated by Lmeans ofthe screws E. The lirst or pulling 6.5
roller is lo be screwed down until there is sufficient power, when turning, to pull the cloth over the cen tral and through the back rollerssay, for example, the front rollers are screwed down to a pressure of one hundred pounds, 7o while the back or tension rollers are only screwed down to fifty pounds. rI he machine is started, and as the cloth is drawn through the back rollers by the revolution of the front rollers the tension or stretch is perfectly the same on every thread.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a machine for stretching cloth, a rub- 8o her-covered roller provided with spiral grooves and with teeth at its ends, substantially as herein set forth.
2. The combination, in a machine for stretch ing cloth, of four spirally-grooved rubber-covered rollersf-viz., two pulling-rollers in front and two holding or tension rollers back, with devices for regulating the tension-and intermediate top and bottom rollers, substantially as shown and described, and for the purposes 9o set forth.
In testimony that I claim the foregoing I have hereuntoset my hand and seal this 26th day of December, 1879.
