Application January 11, 1937, Serial No. 120,102

1 Claim.

The invention relates to a carding machine and more especially to a combined picking and carding machine.

The primary object of the invention is the provision of a machine of this character, wherein the same will open cotton thread in reworked wool and. in this manner eliminating costly carbonizing processes which is necessarily required in mill work today and also will remove the sizing from all kinds of stock, especially rayon.

Another object of the invention is the provision of a machine of this character, wherein the use of a. separate picking machine is avoided in that the picking and carding of the stock will be effected in one operation.

A. further object of the invention is the provision of a machine of this character, wherein picking and carding will be executed on all kinds of stock, such as hair, wool, reworkable wool, silk and vegetable matter, namely, cotton, hemp, jute, flax, rayon, et cetera, and additionally mineral matter.

A still further object of the invention is the provision of a machine of this character, wherein the same includes a minimum number of moving parts thus occupying the least possible floor space and assuring a maximum output.

A still further object of the invention is the provision of a machine of this characten'which is comparatively simple in construction, thoroughly reliable and efficient in operation, assuring a picking and carding in. a single working of the machine, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a side elevation of the carding machine constructed in accordance with the invention.

Figure 2 is an enlarged fragmentary vertical sectional view showing in detail the assembly of the carding cylinder, stock guide, guide roller and pressure roll embodied in the machine.

Figure 3 is a fragmentary perspective View of the stock guide.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the machine as usual comprises a frame A in which is jour naled a main carding cylinder 5 having at its periphery the usual card clothing or Garnett wire 6 while carried by the frame A is a feeding and presser roll 1, its journal 8 at each end being supported in a shiftable bearing 9. The bearing fits in a guide way IE! and acting upon this bear ing is a coiled expansion spring II suitably held in its working relation. to said bearing. The presser roll l at its periphery as shown carries a rubber covering l2 although it may be otherwise surfaced, as for example with card clothing or Garnett wire. In other words, the cylinder 5 and the roll 1 may be covered at their peripheries with light materials or each of a composition. In this instance the roll '5 is covered with a rubber facing at its periphery. 1

Above the roll l is a guide roller I3 suitably journaled for the guiding of the stock M over the roll I. The stock M is supplied to the machine between feed rolls 55, these being suitably journaled.

Supported next to the cylinder 5 and between it and the roll I is a stock guide bar IE, it having the concaved face ll next to the cylinder 5 while another reversely concaved face I8 confronts the presser roll l and this guide bar functions to direct the stock M and to hold the same Workable by the card cylinder 5. The bar It is stationary and the stock is forced past the lower edge l9 by the presser roll l which rotates clockwise and at a speed slower than. the speed of rotation of the cylinder 5, the points of the clothing 6 of the latter being in the direction of rotation of the same and thus a direct carding action will be had on the stock !4 at the point of the edge I9- of the bar it and such stock will be picked up and have full carding action in a positive manner during the working of the machine in that the bar It firmly holds the stock for direct action by the cylinder 5.

The presser roll I acted upon at each end thereof by the spring M will be held closely against the knife edge of the stock guide between the presser roll and the cylinder 5 and this cylinder operates by rotation in the same direction with respect to the roll l but at a greater speed or rotation than the same. The stock in the feeding thereof is carried to the lower knife edge E9 of the bar l6 which is set the proper distance from the cylinder 5 and as the stock is forced past the bar the points of the clothing 6 of this cylinder co-operative with the knife edge l9 will work upon the stock, opening up the threads,

to substantially the line of closest approach of said cylinder and roll, said bar having a concave face adjacent said roll opening gradually outward therefrom away from said knife edge, and means for feeding material to the opening between said bar and roll, said roll mounted for movement radially with respect to said cylinder and having means for pressing it yieldingly toward said knife edge and cylinder.
