IMPROVEMENT IN MACHlNE FOR ROLLlNG FABRICS.

Specification forming part of Letters Patent No. 24,046 dated May 17, 1859f reissue No. 5,029, dated August To all whom it may concern: v

Be it known that I, THOMAS H. hIUllDH Y,.; of the city of New Orleans, in the parish hf Orleans and-State of Louisiana, ha efinvented a new and useful Machine for Rolling Bagging and Gunny-Cloth Fabrics; and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing making part of this specification, in which- Figure l is a vertical central section of my invention taken in the line .1. .r, Fig. 2; Fig. 2- is a front view of the same. I, v Similar letters of reference indicate ('orris sponding parts in the two figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular frame, which may be constructed in any proper way to support the working parts of the device. Bis a driving-shaft, which is fitted in one side of the frame A, and has a driving and an idle pulley, (.l U, placed on it. The inner end of the shaft B has a. hollow square, a, formed in it to receive one end of a rolling-shaft,l),which is placed horizontally in the frame A at its lower part. E is a Windlass, fitted in the frame A, the rope I) of the Windlass being connected by-abook, 0, with one end of the rolling-shaft l), as shown clearly in Fig. 2. F is aslotted bar which is placed in the lower part of the frame A below the rolling-shaft l). This bar F maybe adjusted longitudinally in the frame A, and secured at any desired point within the range of its movement by a. pin, (1, which inlay be titted in either of a series of holes, 0, (see Fig. 2.) G is a roller, which may be of cast-"iron. The journals f of this roller are ntted in bearings g g, which are attached to a horizontal bar, H. The bearings g are titted in grooves in uprights h of the framing, and the roller may be raised, when necessary, by a Windlass, I, (see Fig. 1,) the bearings being allowed to slide freely in the uprights h. On one of the journals of the roller G a cam, i, is placed, the form of which is shown clearly by dotted lines in Fig. 1. J is alcver, the fulcrum j of which is at the outer end of a bent bar, K, attached to the framing H, said bar, at its angle, forming the bearing for a. toothed wheel, L. The lever J has an arm, k, attached to it. Said arm has a pawl, l, secured to it, the pawl catching into the wheel L. M is a spring which is attached to the frame H, and is connected, by a cord, on, with the arm 70 of the lever The operation is as follows: The bagging A or gunny-cloth or fabric to be rolled is passed over a traverse bar, rtflof the framing underneath the Windlass I, through the slotted guide-bar F, and around the bar 1), the roller Gr bearing on the bagging. Power is applied to the shaft B, and the bagging is wound on the shaft D, the bar F serving as a guide, and insuring the even winding of the bagging or cloth on the roller. The roller G is rotated by the revolution of the shaft D, owing to the pressure of said roller on the bagging or cloth, and at each revolution of said roller the lever J is actuated by the earn '5, and the wheel L is'rnov ed one notch, the pawl l actuatin" the wheel L, which is graduated at one side, and records the revolutions of the roller G. When the piece of bagging or cloth is rolled on the shaft D the latter is withdrawn fromthe roller by turning the Windlass E, and

the-shaft is again inserted in the frame to receive a succeeding roll. The roller G is elevated and retained at any desired height by the windlass I, so as to admit of the ready removal of the rolls, and the insertion of the shaft .1).

This machine has been praetieallyflest ed, and it operates well, saving a vast deal of labor, and performing thework far better than it can be done by hand.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The rolling 0r sliding shaft D, in combination with the friction or pressure rollerG and Windlass E, substantially as and for the purposes hereinbefore set forth.
