RUG MACHINE I George H. Morrow, Portland, Oreg. a Application March 26, 1934, Serial No. 71 7 ,293 L V I Claims. (01. ilz-so) My invention relates to improvements in rug making or tur fing machines, having for its particular objects, simplification, inexpensiveness of manufacture and improvements of operation. 5 Essentially the invention embodies a bifurcated or forked frame formed of two alike side memhere or legs, spacedly'held in parallelrelationship by an intervening end or handle member. Between the legs is mounted a reciprocating needle together With the mechanism for, 'im: parting such movement thereto, together with an improved guide for the needle which is readily adjustable to regulate the spacing or distance between needle strokes. I u a 'One of the'principal objects of theinvention is to provide a rug machine which is simple, easy and inexpensive to manufacture. H Another object'of theinvention is to provide improvementsin the needles of rug making or -;Sf turfing machines, whereby the turf or loops are all of the samelength, preventing the pulling of such loops, and avoiding an unevenness or irregularity in the pile of the finished product.

A' further object of the invention is to provide an improved needle guide, one which is easily adjusted for regulating the distance ,or spacing of the needle travel over the. fabric operated uponythe distance between strokes. A continued object of the invention is to pro- 3 vide a device of this character constructed of such few andsimple parts that the average personmay readily understand and operate it.)

Furtherobjects and purposes. offthe invention will be ascertained upon. reading the specifica ,35 tion following, assisted by the accompanying drawing, wherein: I Figure 1 is a perspective of the invention.

Figure 2 is a fragmentary, rear elevation, partially'in section, of the invention f Figure 3 is a fragmentary perspective illustrating the adjustable needle guide.

Figure 4 is an. elevation of a needleemployed in the invention. 4

Figure 5 is a perspective of the needle guide. .45 Figure 6 is a side elevation, illustrating'the' invention in operation. .7

Similar characters refer to similar parts throughout'the several views. I In the drawing my invention 'will"be seen as consisting of a frame 1 formed'of two alike and interchangeable side members or legs v2 secured to an ,interveningspacer'S. Members 2 are somewhat elongated andare secured to opposite sides of spacer 3 by any suitable means such as the screws 4.

Members

2 and 3 may be of any members or heads, orstops 22.

material suitable. for this purpose. As will be seen spacer 3 is considerably shorter than side members 2, this being in order to provide a space 5 between suchsldemembers which extends the major portion of their length.- The end of frame ,1 Where legs 2 and spacer Bare joined'constitutes the handle portion of the device.

The lowerend of each-leg 2 has an elongated guide carrying slot 6. These slots are identical ineach legand extend lengthwise thereof. On i the outer face of each leg in the region of the slot 6 are out or otherwise indented notches 7-. Slots 6- and notches '7 are for holding and posi-V tioning a guide hereinafterdescribed. The lower ends 8 of legs2 are treads or feet, and frame 1 is helduprightupon such feet while being operated. l V

The invention employs a hollow or cylindrical needle 9-provided with a shankor pitman upper portion 10 terminating in a bearing slot 11 opening through one edge-of such pitman. i This seats upon crank--13 of crankshaft 12. A slide 11a, movable back and forth on pitman 10, is provided with a fingerllb which may be slid over the opening into slot 11, closing it and prohibiting the needlefrom becoming detached. The foregoing p rmits of ready exchange of needles, thereby permitting different sizes of needles to be. employed.- Crankshaft -12 hasbearings or

spindles

14 and 15, andan operating crank and handle 16 and 17- respectively. Spindles or

bearings

14 and 15 are rotatably carried in legs 2, as indicated in Figure 2, with needle 9 operatively connected to crank 13 as heretofore indicated. In order to maintain needle 9 inits proper operative position, 0 and to properly guide it in its operation, a suitable guide,18 is provided; Guide 18 consists of a central or guide portion 19 having an aperture 20 in which'needle 9 operates as particularly shown Figure 3. Extending from opposite sides of the central portion 19 are radially projecting portions or arms 21 terminating in

cross Members

22 and 21 together form T-shaped arms projecting from the central portion 19. The arms 21 extend through slots 6 of legs 2 with heads 22 bearing upon the outer facesthereof. Each head 22 ex: tends across aslot 6, and the heads being longer than the width of such slots, they cannot pass therethrough unless member 18 is turned axially ninety degrees, The normal condition of the heads, as shown in the drawing, is transversely over such slots.

The inner faces of the heads 22 are V-shaped at 23 to enable them to seat in notches '7 which are likewise V-shaped. The distance between the inner faces 23 of heads 22 is less than the distance between the outer faces of legs 2, therefore, when guide 18 is in the position shown, legs 2 are sprung together somewhat, as will be seen in Figure 2. The urge of the legs 2 to unspring or assume normal position causes them to press against the V- faces, thus holding such faces in the notches 7, and consequently the member 18 against shifting. In Figure 2 it will be noted that there are more than one notch on each leg, there being six in this in-. stance, one above the other. This provides for six positions in which member 18 may be posi-'- tioned. The vertical position of guide 18 governs the spacing or length of the stitches made by needle 9. Needle 9 fulcrums on guide 18, hence" when guide 18 is maintained in the uppermost notches '7, the lower or penetrating end of needle 9 rocks its greatest distance, while the'reverse is true when guide 18 is held by the lowermost notches, and the intermediate notches provide for altering the rock of the needle to intermediate degrees. 7

As before stated needle 9 is hollow or cylindrical, and the thread or yarn used by the machine is threadedtherethrough. To this end an opening 24 is provided in the intermediate bodyportion of the needle. The lower end of the needle is cut away on one side as indicated at 25, and inwardly curved from the point or region 26 to its lower end, thus providing the penetrating point 2'7. Yarn 28 is threaded through openingj24 into and through the body of the needle andout through the cut away portion 25. -An eye 29' is provided in the curved end of 'the needle, and the yarn passing out of the cut away portion25 is passed therethrough. After this has been done the needle is ready for operation.

In operation, the machine is used iii-conjunction with pattern lines delineated upon a fabric, such as burlap. The machine is held'upright by the handle with the feet 8 astraddle' of 'the'line to be followed. Crank 16, by means of handle 1'7,v is operated. This causes the needle to alternately penetrate and recede from the fabric. As it penetrates the fabric it carries the yarn therethrough, and as it recedes it leaves yarn-in the form of loops 30, as shown in Figure 6, on the side of the fabric opposite to which the machine is operated. The needle by reason of the fulcrum'established in the member '18, recedes from the fabric to the rear of legs 2, as shown by the dotted outline in Figure 6, and enters the fabric forwardly of such legs, as shown by fullline in Figure-e. *Thusas it alternately enters and reconstruction of the present needles Needle 9 penetrates the fabric 31 'to approximately the point 26 where its lower curvature commences. There'- fore, by reason of such curvature, its widthdecreases as it is being withdrawn, and the pressure against the yarn or frictional pull decreases, leaving the loop undisturbed on the underside of the fabric 31.
