My invention relates to knitting or weavingdevices of the type wherein tworowsof fingers are provided in parallel bars and weaving or-knitting is efiected by looping .the yarn overthe fingers in various patterns and causing the finished work to pass between the bars. L v l As its primary object my invention is-intended to provide a knitting, device having improved knitting fingers which facilitatethe formation of a uniform weave and'which enables the knitting process to be carriedon with minimum isual attention, thus providing a device which is particularly suitable for use byphysically handicapped persons,.or those whose eyesight is impaired. r

Another object isto provide a knitting or weaving device in which the knitting fingers and bars which carry them'are integral, and which may, infact, be formed from extruded metal, preferably aluminum; so as to provide a light weight but strong tool. 7

With the above and other objects in view as mayappear hereinafter, reference is directed to the accompanying drawings, in which I igure 1 is a fragmentary plan view of my knitting device.;

Figure 2 is an enlarged transverse sectional view through 22 of Fig. 1, showing particularly the means for adjusting the spacing between the finger bars.

Figure 3 is another enlarged transverse sectional view through 3-3 of Fig. 1, indicating partially the manner in which stitches are looped over the knitting fingers.

Figure 4 is an enlarged fragmentary sectional view through 44 of Fig. 3, illustrating the manner in which the knitting fingers are disposed at the extremities of rudimentary ribs, which facilitate the removal of the stitches as the knitting or weaving progresses.

Figure 5 is an elevational view of a typical hand tool employed with my knitting device to remove the stitches from the knitting fingers.

A pair of finger bars I is provided which are preferably in the form of extrusions of hollow rectangular cross-section. Each finger bar is provided on its upper side near one vertical wall with a series of knitting fingers 2. Each series of knitting fingers 2 is integral with its finger bar I and, initially, is in the form of a single continuous rib forming a part of the extrusion. The individual fingers are formed from said rib by milling the rib crosswise.

Each knitting finger 2 comprises a tapered shank 3, one edge of which is essentially parallel 5 Claims. (ClrGHl v 2. I v to but offset a slight distance back of the adjacent vertical side of the finger bar. This side ofthe shank curves inwardly over the finger bar'and the upper end of the shank terminates in a semicircular offset head I, whichbefore milling the rib is inthe form of a, continuous bead. 1

Each knitting finger is disposed on a rudimen-v tary ridge 5 extending transversely on the upper side of the finger bars. The ridges 5 are formed simultaneously with the milling operation which separates the knitting fingers by causing the milling cutter to out below the normal upper sur-, face of the finger bar. The adjacent upper cor ner of each bar is so extruded that it coincides with the milled surface of the finger bar between the ridges 5 rather than the normal upper surface of the bar andforms a rudimentary depressed shoulder. 1

When theknitting bars are placed in parallel spaced relation with their knitting fingers at the adjacent sides. of the finger bars, the knitting fingers extend upwardly and curve away from each other, as represented best in Figs. 2. and}. The fingerbars are held in adjusted spaced relation by means of connecting shafts 1. A pair of these shafts is secured at 8 adjacent theextremities of one of the finger bars and extends through appropriate openings in the other finger bar. The extremities of the shaft 1 are threaded in the screw members 9, having shanks l 0 which are journaled within their corresponding finger bar and are held in place by means of a groove H and are intersected by tangentially disposed retainer pins l2 through the finger bar I. The protruding portion of the members 9 have knurled heads l3.

The shape of the knitting fingers is of primary importance; for, by reason of the diverging relationship between the adjacent surfaces of these fingers and the ofiset disposal of the heads 4, the knitting operation is greatly facilitated; that is, the loops of yarn may be readily drawn over the finger bars and retained by the heads. In a succeeding step of the knitting operation the loops are removed by a hand tool [4. The hand tool itself is conventional but is illustrated in order to explain the function of the ridges 5. The end of the hand tool is formed into a curved and tapered hook I5 which is adapted to ride along either side of the shoulder formed by ridges 5 and slip under a loop of yarn so that the loop may be raised around the ofiset head 4 and oil of the knitting fingers. By reason of the guiding action afforded by the ridge 5, the step of removing the completed stitches is greatly knitting devices intended to accomplish the samepurpose as the device herein described, have been made. These, however, comprised wooden finger bars in which a series of nails or screws were. placed along the bars, which ha proven to be a tedious and expensive method of construction; some fifty fingers being provided in each bar.

Furthermore the shape of these fingers is much inferior to the shape which applicant has found by experimentation to be eminently satisfactory. Quiteapart from'this, however, applicanthas found that by extruding each finger bar and its series of knitting fingers as a single extrusion having the cross-section depicted in Figs. 2 and 3, the intervening material between the knitting fingers may be milled quickly and economically. It is then merely necessary to buff the fingers by a longitudinual movement with respect to the finger bar to finish the corners of the knitting fingers.

Although there has been, described a specific embodiment of the invention, it is to be understood that various modifications may be made thereinwithout departing from the spirit of the invention or the scope of the appended claims. Iclaim: I a 1. A knitting device, comprising: a pair of opposed and spaced finger bars; sets o'fintegral upstanding fingers spaced in staggered relation along the confrontingupper margins of said bars, said fingers including upwardly tapering shanks, the upper portions of the shanks of the opposed sets of fingers curving away fromeach other and terminating in rounded head elements on their remote sides. i

2 A knitting device, comprising: a pair of op- 4 posed and spaced finger bars, sets of integral upstanding fingers spaced in staggered relation along the confronting upper margins of said bars, the confronting sides of the fingers of each set curving away from the fingers of the other set and terminating in stitch retaining head elements on their remote sides, and means for securing said bars in adjustable spaced relation with each bhe f 3.,A knitting device, comprising:-' a pair of opposed and spaced finger bars, the upper surfaces of said bars having rudimentary sets of transversely extending staggered ridges, and integral upstanding knitting fingers at the adjacent extremitie of saidsets of ridges, said ridges forming with said bars guide shoulders along the sides of said knitting fingers and continuing therefrom partially across said finger bars.

A knitting device, comprising: finger bars, the upper surfaces having a plurality of integral upstanding knittingfingers; and integral ridges equal in width to said knitting fingers extending from thebase ends thereof partially across said bar to form guide shoulders for a pointed tool when said tool is moved across the bar and alongside said fingersI 5. A knitting device, comprising: finger bars, the upper surfaces having a'plurality of integral upstanding knitting fingers; and integral ridges equal in width to said knitting fingers extending from the base ends thereof partially across said bar to form guide shoulders for a pointed tool when said tool is moved across the bar and alongside said fingers, each of said fingers curving upwardly and over said finger bar and having heads overhanging said ridges.
