EMIL J. FRANCK, OF PHILADELPHIA, PENNSYLVANIA.
Application med February 8, 1919.
To all whom it may concern:
Be it known that I, EMIL J. FRANCK, a citizen oi:1 the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improve `ments in Attachments for Knitting-Ma- .hinged or pivoted to a frame or other part of the machine which supports the needles, but hitherto a difficulty has been encountered in that the gears which transmitted motion from the Jframe or appropriate parts carried thereby to the brackets, or appropriate parts carried thereby for driving the dial or other parts carried by the bracket, got out of mesh when the bracket was swung or turned, so that when the bracket was returned care had to be exercised to get the proper teeth of the gears in mesh, :for otherwise parts of the machine would be out of time with other parts, and in fact it is customary to mark the gears and rely upon the operators bringing them into mesh in the manner indicated by the marks, but this the operators frequently failed or neglected to do.
The principal object of the present invention is to overcome these defects and disadvantages and to provide gears that will remain in mesh during all ordinary swinging movements of the bracket or hinged support.
The invention will be claimed at the end hereof, but will he first described in connection with the accompanying drawings, forming part hereof, and in which* Figure l, is a top or plan view.
Fig. 2, is a sectional view illustrating features of the invention. i
Figs. 3 and 4 are respectively an elevation, partly in section, and a section on the line 4.-4: of Fig. 3.
Fig. 5 is a top or plan view, partly in section, illustrating a detail, and
Figs. 6 and 7 are sectional views illustrating modications.
In the drawings l is a :trame carrying Specification of Letters Patent. i

Serial No. 275,736.
the knitting mechanism that includes the needles which are not shown. This frame is provided with driving gear, collectively indicated by 2, that is well understood and may assume various forms and does not require detail description. 3, is a bracket pivoted to the frame for swinging movement and this bracket may constitute the latch ring and it carries driven gear, collectively indicated by Il, and its complemental dial 5. There is nothing particularly new about the mechanism so far described. There are a pair of constant mesh toothed wheels which have their outer pitch circle, or more accurately, one of their outer pitch circles arranged to pass through the pivot ot the bracket to keep the wheels in mesh in all positions of the bracket within its range of swinging movement.
As shown in Fig. 2, the bracket is pivoted at 6 and the outer pitch circle 7 passes through the pivot 6 so that when the bracket is turned counter-clockwise the gears 8 and 9 remain in mesh adjacent to the outer pitch circle. As shown in Fig. 6, the bracket is pivoted at 6a and the inner pitch circle 7a of the gears 8a and 9a remain in mesh when the bracket is turned up. In the cases described, the ears are of the bevel orl miter variety. Iowever, as shown in Fig. 7, the bracket is pivoted at 6c and the pitch circle 7 passes through the pivot so that the gears 8C and 9c remain in mesh when the bracket is swung upward about its pivot. The described combination and arrangement oi bracket and pivot with an outer pitch circle or circle of the gears insures engagement of the gears or constant mesh of the gears in all positions of the bracket, so that the bracket may be swung up and down as necessary without getting the gears out of mesh.
What I claim is:
In an attachment for knitting machines the combination of a `frame carrying needles and provided with driving gear, a bracket pivoted to a liXcd part of the frame for swinging movement in respect to the frame and carrying a driven gear, and a pair of constant mesh toothed-wheels having one of the outer pitch circles passing through the fixed pivot point of the bracket to keep the wheels in mesh and oppose turning movement when the bracket is swung.
