SUPPORT FOR ELECTRICALLY DRIVEN AWLS FOR FABRICS Filed Oct. 14, 1940 BENJAM/N LANG- INVENTOR.

BY Wx (fin Ab. I ATTORNEY Patented Dec. 2, 1941 Benjamin Lang, New-York,NL Y.

Application October 14, 1940, Serial No. 361,093

1 Claim.

This invention relates generally to devices for cutting holes in textile materials but more specifically to a support to which the stand of an electrically driven awl is attached, the said support being adapted to receive a plurality of plies of cloth through which the awl is adapted to penetrate.

The main object of the invention resides in the provision of a support for an electrically driven awl used to cut holes in a stack of plies of cloth wherein the awl in its lowermost position after penetrating the lowermost ply of cloth impinges against a soft portion of the support thereby eliminating the danger of perforating the table top on which the awl apparatus rests.

A further object of invention resides in the provision of a support both for the mounting of an electrically driven awl and of a plurality of plies of cloth or fabric adapted to be perforated by the said awl, a portion of the support being provided with a soft material which permits penetration of the awl therein after the said awl has cut through the thickness of the cloth plies.

Another object of the invention resides in the provision of a support for electrically driven awls used in the garment industry for the cutting and perforation of cloth, which is economical to manufacture, easy to operate, and which preserves the table top from damage.

These objects and other incidental ends and advantages of the invention will hereinafter appear in the progress of the disclosure and as pointed out in the appended claims.

Accompanying this specification is a drawing showing a preferred form of the invention wherein corresponding reference characters designate corresponding parts throughout the several views, and wherein:

Figure 1 is a side view in elevation showing a support to which an electrically driven awl is attached.

Figure 2 is a reduced plan view of Figure 1 with the plies of cloth removed.

In accordance with the invention and the preferred form shown in the drawing, a plurality of plies of cloth designated by numeral H] is adapted to be cut or perforated by a conventional awl H adapted to be rotated by a motor I2 secured to a standard 13. Hitherto it has been the practice for standard 13 or for any other supporting device to rest on a table top It while the plies of cloth also rested on the table top proximately thereto under the awl ll whereby the latter could be made to penetrate the plies LII of cloth l0 until the bottom-most ply was penetrated, the table top serving as a stop for the awl. Conventional means for raising and lowering awl II have been employed in operation such as the use of a slidable standard l3 within a cylindrical bearing member resting on a table top.

To avoid using the table top as a stop for awl H after the latter-has penetrated plies of cloth It, a stand has been provided preferably of metallic material, having a base member IS with a downwardly inclined front edge l5. Extending upwardly from the rear edge of base member l5 and preferably intermediate the width thereof is a bracket member M having vertical and horizontal arms Ma and Mb respectively. Arm Mb is inwardly disposed and is adapted to have an upwardly disposed cylindrical bearing member Mc adapted to slidably receive standard l3. Communicating with the bore of cylindrical bearing Me is a cylindrical cut-out Md. The distance of travel of standard l3 within bearing Md and cut-out Md should slightly exceed the depth of cloth plies I0 whereby awl ll may be able to penetrate the total thickness of cloth Ill and go slightly beyond to engage a soft filler such as cork l8 as will hereinafter appear.

Between base member l5 and the underside of horizontal arm Mb of bracket M, plies of cloth H] are adapted to be held in position, the inclination of front wall l5 making it easy to push said plies into place. The upper surface of base member l5 opposite the position of awl I l is provided with a preferably cylindrical cut-out portion I! within which is placed a yieldable and soft material such as cork 3, the upper surface of the latter being flush with the upper surface of base l5.

It is to be observed that as awl H penetrates plies of cloth ID, the said awl will engage cork portion [8 in its lowermost position, the lowering of awl l I through the plies I0 being accomplished as shown in the drawing by the sliding of standard l3 in bearing Me by the action of gravity and hand control. When the bottom of standard l3 reaches the bottom of Md, awl II should engage cork l8 but should'not go below the bottom surface thereof. It is not necessary to have plies of cloth l0 covering the full distance between the lower surface of horizontal arm Mb and base l5 for operation of the invented stand herein.

It is preferable to utilize a weight such as plate i 0a to superpose the top ply of the cloth. Weight Illa is provided with an opening lllb therein to enable awl H to engage the plies of cloth, the

weight Hla preventing shearing dislocation of the plies during the cutting of holes therein. The weight Illa may be provided with handles, if desirable, for removal and for application. It is to be noted that when weight Illa is used, the latter is adapted to engage the undersurface of the horizontal arm Mb.

I wish it understood that minor changes and variations in the position, location, material, integration and construction of parts, may all be resorted to without departing from the spirit of the invention and the scope of the appended claim.

I claim:

A support for a fabric perforating awl and the supporting arm of the driving apparatus associated therewith, including a base member having an inwardly turned flange whereby the plurality plies of fabric are insertible therebetween, a bearing member secured to said flange and adapted to slidably engage the said supporting arm, the base member opposite the awl having an easily penetrable portion to serve as a downward stop for said awl after penetration through the plies of fabric, and a removable weight member adapted to overly substantially the full area of the top ply of fabric and adapted to be positioned below the said flange and having an opening therein through which the said awl penetrates.

BENJAMIN LANG.
