LOOM

GUM mu thereof around which is rove a thread which is Patented Jan. 7, 1941 aren't OFFICE 1 Claim.

' This invention relates to a hand loom'and more particularly pertains to thetype of hand loom:

embodying a rectangular frame fitted with a series of upstanding Weaving pins on each side first carried back and forth to extend between the pins on opposed sides of the frame and is then passed back and forth to extend between the pins on the other opposed sides of the frame after which by the aid of a needle the thread is interwoven with the initially arranged crossed rows of threads in weaving a desired design. Heretofore it has been the practice to make such looms by driving metallic pins or pegs in rows along the side members of the frame in order to provide the series of upstanding weaving pins around the frame. These pins are quite numerous, even for a frame for weaving a. mat four inches square since the pins are disposed about one-eighth of an inch apart. Accordingly considerable time is consumed in setting the pins one at a time, or costly machinery is required to assemble the pins in groups, thus resulting in rendering such looms costly to manufacture.

The main object of the present invention is to provide a construction whereby the setting of pins or pegs is obviated and the manufacture of the loom greatly facilitated, and whereby its cost of producing is greatly reduced.

Another object is to provide a construction in which rows of interconnected teeth are employed in lieu of pins and in which the assembly of teeth may be readily removed from the frame and replaced thereon as desired by the operator.

Another object is to provide a construction in the loom whereby the manipulation of the weaving needle will be greatly facilitated.

Another object is to provide a formation in the teeth of the loom whereby accidental slipping of the threads therefrom will be prevented.

Another object is to provide a construction whereby a loom frame may be adjusted to adapt it for weaving rectangular pads of various sizes.

With the foregoing objects. in view, together with such other objects and advantages as may subsequently appear, the invention is carried into effect as illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of the loom;

Fig. 2 is a View in elevation of a toothed cross bar employed in converting the loom to a smaller size;

Fig. 3 is a detail in section as seen on the line 3-3 of Fig. 1;

Fig. 4 is a section and elevation taken on the line 33 of Fig. 1 showing the manner of assembling the adjustment bar shown in Fig. 2;

Fig. 5 is a plan View of a loom depicting the manner of varying the size thereof;

Fig. 6 is a view in elevation of a portion of one ofthe toothed members employed in the loom; showing it as detached; i

Fig. 7 is a detail in perspective of a modified form of the toothed member.

Referring to the drawing more specifically A indicates generally the loom frame which embodies four rails ll] assembled in the form of a rectangle, and each of which rails is formed on the upper face thereof with a longitudinally extending groove H in which is removably inserted a toothed strip B which is preferably formed of fiber board but which may be stamped from sheet metal; the groove H in each rail extending throughout the length thereof and intersecting the grooves in the adjacent rails, and the strip B being formed of a length less than the length of the rail and of the groove to which it is applied whereby the strip may be adjusted lengthwise in either direction within the confines of the frame.

The strip B embodies a base portion M which is adapted to snugly fit the groove II, and on which portion is formed a series of teeth IS the tips of which are formed with protrusions l6 for preventing threads passed around the teeth from slipping off the ends thereof. The base portion I4 is of such width relative to the depth of the groove II that its upper edge will project above the plane of the frame A so as to provide ledges l1 between the bases of adjacent teeth I5 which serve to space threads from the frame and also to facilitate rocking of a weaving needle vertically when extended between the teeth in effecting inter-weaving with cross threads.

The protrusions l6 may be formed to extend laterally between adjacent teeth as shown in Figs. 1 and 6, but in some instances, as where the strip B is formed of metal, the protrusions may be upset in the metal in such a manner that they project from the outer faces of the teeth as shown at It in Fig. 7. Protrusions of this character leave the spaces between the upper parts of the adjacent finger-like teeth entirely unobstructed, and yet serve to keep the threads in place.

In order to facilitate fastening the end of a thread to the frame preliminary to roving the thread around the pins, a thread engaging slit H3 is formed in one of the rails of the frame adjacent an end thereof, as shown in Fig. 1.

B the ends of which protrude from the ends of the bar 20, which latter is formed of a length to extend between opposite rails of the frame and snugly fit thereagainst, while the protruding ends of the toothed strip thereon are engageable in the grooves [9 to anchor the bar 20 in place, as shown in Fig. 4, and to align the cross bar and the toothed strip thereon parallel with side rails of the frame, as shown in Fig. 5. By use of the cross bar 20 various sizes of rectangular arrangements of the tooth strips may be formed. with a single rectangular frame A so as to enable weaving of various sized mats or strips on a single loom.

The mode of weaving a mat on the loom here set forth is the same as that commonly employed in looms of this character, and accordingly requires no explanation here; the essence of the present invention residing in the manner of constructing and assembling the weaving pins or teeth, and whereby the teeth assembly may be stamped. or punched from sheet material and inserted in the longitudinal grooves of the rails of the loom frame.

I claim:

In a loom, a rectangular frame comprising a series of rails, each of which rails is formed with a longitudinally extending groove on a front face thereof extending throughout the length of the rail and intersecting the groove of the adjacent rails, a strip of sheet material having a. base portion and a series of teeth projecting from said base portion, said base portion being inserted in said groove with the edge thereof from which the teeth project in outwardly spaced relation to said frame; each of said strips terminating in an end tooth at each end thereof and being arranged on said frame with the end teeth of adjacent strips spaced apart, each of said strips having a length shorter than the rail and the groove to which it is applied and being arranged with its ends spaced inwardly from the ends of the groove in each rail to afford a space at each end thereof and thereby allow longitudinal adjustment of the strip in either direction within the confines of the frame.
