Description
ALLEN PULLEN, OF CHICAGO, ILLINOIS,
enL'r-rnnronnrrrra einen.Y
No. 911,608. Specification ci Letters rement. Patented ret. e, ieee.
Application filed. January 13, 1908. Serial No. 416,685.
To all whom tt may concern:
Be it known that-l, ALLEN PULLEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and useful lmi provenients in Belt-Perforating Gages, of which the following is a description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding letters of reference in the different igures indicate like parts.
Great difficulty has heretofore been found in connection with the use of wire lacing for machinery belts, owing to the fact that the perforations in the belts are often improperly located, thereby subjecting portions of the belting to undue stresses and causing the lacing to be torn out.
' rlhe object of my invention is to overcome this diiiiculty by providing a simple and efflcient gage whereby the perforations maybe properly located with respect to the stresses to be borne and .accurately made when so located ;-all of which is hereinafter more particularly described and definitely pointed out in the claims.
ln the drawings, lii ure lis a plan view of my improved gage s rowing the manner of applying the saine to a belt, Fig. 2, is a like view showing a modified application thereof,
and Figs. a and 4e are sectional views taken upon the line 3, llig. l viewed in the direction bent at right angles of the arrow there shown,-Fig. 3 representing the4 gage in position before the belt is perforated, and Fig. e showingthe same as it would appear after the belt is perforated. Referring to the drawings, a represents generally i an elongated plate, preferably formed from sheet-inetah the length of the plate being sufficient to conform to the width of the widest belt to which the user may have occasion to apply it. Upon one edge of said plate which is made straight, is formed a flange b, better shown in Figs. 3 and 1i, which is preferably extended throughout the length of the plate to form an abutment to bear against one of the ends of the-belt in the manner indicated in theI drawings. vThe edges of the ends d e respectively are made straight and at right anglesto the flange t. ln order to hold the plate securely'in the desired position, l provide a plurality of pronos or spurs f, upon its inner face which are, by preference, cut from the plate and thereto, as shown.
In perforating a belt for use with wirelacing, it is ofthe utmost importance that the perforations should not only be in alinement but that the distance thereof from the ends of the belt to be joined should bear a givenl ratio tothe thickness of the latter. ln the example shown, I have provided two rows of perforations g and h respectively, in the plate a, which are intended to serve as guides for locating the erforations in belts of varying thickness. n belts of a predetermined thickness, the guide holes should be employed; while in thicker ones the holes 7?, should beused. lt will be noted, in the example shown, that the holes g and h are staggered with respect to each other. The pur ose'of this is to locate the second row of oles at. the proper distance from the end of the belt while at the same time properly disposing the end holes at requisite distances from the opposite edges thereof. With this disposition, it becomes necessary to vary the endwise adjustment of the plate for the two sets of'holes. ln applying the device, if the holes g are to be used as a guide,
then one of the ends d should be placed flush with the edge ofthe' belt, as shown in lfig. l. This causes the end holes g to be located at proper andv equal distances from the edges of the belt. As a guide to the use of the holes h, l cause notches y' lc to be formed in the respective kends of the late, one of which may be placed flush wit one edge of the belt as shown in Fig. .2.
When the'plate is properly adjusted for either set of holes, the spurs f are driven into the leather and the perforations made by means of a suitable punch through the openings desired. ln Fig. 4 a perforation l is shown in registration with one of the openings 7L.
lt will be seen from the foregoing that the gage may be applied-nto belts of varying width and adjusted to either edge according as the user may be right or left-handed.
j Having thus described my invention, l
claim zl. A belt perforating gage comprising a sheet metal plate having a guidin guard upon one edge to engage the end of t e belt, Vsaid plate having a plurality of series of openings therein, each series being parallel the inner face of said plate to enter the body of the belt to hold said plate in position during the operation of punching the belt.
2. A belt perforating gage, comprising a to said edge and rigid spurs projecting from and the first opening of a predetermined series after the iirst.
In testimony whereof, I have signed this speci'lication in the presence of two sub-15 scribing Witnesses, this ninth day of January 1908. l
ALLEN PULLEN.
