IMPROVEMENT IN STRlPPER-CARRYlNG FRAMES FOR CARDlNG-MACHINES.

Specification forming part of Letters Patent No. 115,185, dated May 23, 1871.

To all whom it may concern:

Be it known that I, JOHN F. Foss, of Low Massachusetts, have invented certain new and useful Improvements in OardStripping Ma= chinery, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specification, in which--- 7 Figure 1 represents a transverse sectional elevation through the center of the main cylinder. Fig. 2 is an end view, and Fig. 3a detached section of a portion of an ordinary mangle-motion, showing several of the pins and the operating-pinion.

This invention relates to certain improvements in the machinery or apparatus which is used for stripping the flat tops of cardingmachines, and to that of the apparatus which carries the lifting and stripping mechanisms.

struction of the stripper-carrying arms or frame-work, and in the mode or means of applying the latterto the main cylinder-shaft, whereby the traversing of the arms or framework is performed by a single traversing mechanism at one end of the machine, thereby saving considerable in the cost of the apparatus.

In the said drawing, A represents the cylinder, arranged on a central shaft, B, and supported in boxes or bearings (J, on the frame D, as usual. The stripper-carrying arms E are constructed each with an offset,'g, a shaftreceiving hub or plate, f, and lower dependin g extremities I, which extend below the cylinder, where they are firmly connected by a cross bar, H, and this crossbar maybe of sufficient specific gravity to serve as a counterbalance, and thereby partially or wholly overcome the action of the load upon the upper portion of the arms. This lower crossbar placed a suitable distance below the cardteethon the main cylinder, say from one to light waste and fibers of cotton which accu mulate beneath the cylinder, by crowding such waste substance away from beneath the cylinder and off at the sides of the machine at each forward and backward traverse or 0s cillation of the bar. A secondv crossbar G,

is firmly secured to the tops of the strippercarrying arms E, and this, with the arms and thelower crossbar, constitutes a rigid and substantial frame-work capable of being operated, traversed, or oscillated from one side of the machine to the other by a single traversing mechanism, which may be any of the wellknown devices used for that purpose.

" In the present instance I have shown a very common traversing apparatus, consisting of a curved row of pins arranged beneath the card-arch, and a pinion-gear, c, which operates on all the stationary pins around both end pins, and on either side of all of them. Any other common traversing device may be employed in connection with my said improvement, and such traversing device will only be required on one end of the card, which saves in the cost of the apparatus.

It willbe observed that the arms E are carried close to the ribs K, or top flanges of the arches, and that the ofl'set in each arm carries the shaft-receiving hub and the depend ing lower extremities of the arms inside of the frame-work.

This construction and arrangement of the arms is designed for a twofold purpose: First, to furnish means for applying the lower crossbar; and second, to allow the pulleys on the main cylinder-shaft to be carried nearer the frame-work or end of the machine, and thereby economize in room or space by bringing the carcls nearer together, which enables me to add at least one card to each row or set of cards in a room or section, thereby increasing the carding capacity of the section, room, or mill.

In Fig. 1 I have shown a top flat, M, (so called,) in its common position above the arches, with card-teeth e on the top flat, and also on the cylinder, to show the relative position of the parts.

I claim as my invention- 1. The stripper-carrying arms E, constructed as described, each with an ofiset, g, a shaftreceiving hub or plate, f, and adepending lower portion, I, arranged within the framework, whereby the lower cross-bar H can be applied in the manner and for the purpose described.

2. The strippcr'carrying arms, constructed as: described, in combination with and connected. by cross-bars H and G, all constitutarranged between the end frames D, for the purpose and in the manner substantially as ing a frame-work capable of being traversed described. or oscillated from one side of the card to the other by a single traversing mechanism, substantially as described.

3. The lower cross-bar H, in combination .with and carried by the depending arms 1,
