TIP-MEASURING- APPARATUS.

Application led October 24, 1911.

To all whom t may concern:

Beit known that I, DAVID EDWARD GALLO- WAY, a citizen of the United States, residing at Clifton Heights, Delaware county, Pennsylvania, have invented certain Improvements in Tip Measuring Apparatus, of which the following description, in connection with the accompanying drawings, is a specication, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to shoe making machinery and particularly to shoe measuring devices adapted for use to assist the workman in ascertaining and recognizing the proper location of certain points or lines of the shoe upper relatively to the last.

The invention is herein shown as embodied in a tip measuring device or apparatus adapted for use on or in connection with a pulling over machine of the type shown in United States Letters Patent 663,7 77 and the invention will be explained in connection with that machine.

The tip line or the seam that extends transversely across the forepart of the shoe upper and usually unites a toe tip or cap to the shoe vamp, is a prominent line on the shoe and its relation to other portions of the shoe is of great importance in determining the appearance of the shoe. For these reasons much attention is given to the position of the tip line longitudinally of the shoe by which a long or a short tip is determined and uniformity in length for the two shoes of a pair and the pairs of a case is obtained. Also great care must be exercised to insure that the tip seam shall extend at the selected angle to the median line of the shoe. This angle differs in different styles of shoes, being a right angle in some styles and an oblique angle and inclined forwardly toward the outer or the inner side of the shoe in other styles. It is one of the steps of the pulling over operatio-n to locate the tip seam correctly and when that is done carefully it has consumed an appreciable portion of time becauseit has in practice been done by the use of a graduated scale'of peculiar shape which had to be picked up and fitted to the shoe each time it was to be used, and then sometimes dropped while an adjustment of the upper was being made and then applied to the shoe a second time to ascertain if the correction made by the adjust- Specification of Letters Patent.

tips in pulling over machines by largely eliminating the handling of the measuring instrument.

A very important feature of this invention consists in the combination with means for operating on a shoe of a tip measurer which is movable into position over the top face of the toe where it discloses to the operator the position of the toe tip seam at t-he end of the operation of said means on the shoe.

There are certain obvious advantages in measuring over the top face of the toe where the most conspicuous portion of the tip seam is located, and it is also very desirable to havevthe measurer disclose the position of the tip seam at points separated laterally of the shoe far enough to show the Obliquity, if any there be, of the seam to the median line of the shoe. Prior measurers which have been proposed have embodied one or the other of'these features but it is a feature'of the present invention to provide a tip measurer having both of these important characteristics. This feature of the invention is embodied in a measuring plate that extends across the tip seam on the top face of the toe and through which graduations can be seen at a substantial distance from either side of the median line o-f the shoe. As shown this plate is made of material through which the tip seam can be observed while covered by the plate. Such transparent material or material which approximates transparency enough to serve this purpose is found in so-me of the grades of celluloid which I have used to good advantage. The plate may be thin and flexible enough to bend for adapting itself somewhat to the shape of the toe surface over which it is applied.

A further feature of this invention consists in the cooperative relation of the tip measurer to the pulling over means of the illustrated machine. As shown the tip measurer is mounted so that it can swing downwardly and backwardly from an inoperative posit-ion to carry the abutment against the toe end and the graduated plate over the tip seam. Retaining means is provided tor causing the measurer to remain automatically in tip position indicating relation to the shoe. This permits the operator to use either or both hands tor making adjustments ot the upper which may be required to correct the position of the tip seam and enables him, by instant comparison with the gage, to see when the desired adjustment has been secured. A spring is arranged to restore the measurer to upraised position when the retainer is tripped. Such tripping can be done by the hand or it will be done automatically when the machine is restarted tor the overdrawing and fastening operations.

The several teatures ot this inif'ention, including certain more important details ot construction and principal combinations ot parts will appear more fully from the t'ollowing description and then be pointed out in the claims.

Figure l is aside elevation of so much of the machine ot said prior patent equipped with this invention as is important to consider in connection with this invention. Fig. 2 is a perspective view ot the new tip measurer. Fig. 3 a fragmentary view showing certain of the upper adjusting mechanism. Fig. 4 is a section in a plane perpendicular to the shoe bottom through that mechanism.

The pulling over machine shown as a whole in said patent comprises toe and side grippers 2 and 4 and operating connections t'rom the power shaft thereto for causing the grippers to seize the upper, updraw it with relation to the shoe bottom rest or sole rest and then come to rest holding the upper under tension. When restarted the grippers are actuated to overdraw the upper into position to be secured upon the shoe bottom, the side clamps seize the shoe and the tackers G advance and tasten the upper. The side grippers are connected with rack slides 8, Fig. 3, that engage respectively the upper and lower sides ot toothed portions ot a shatt l0 trom which depends the tip straightening lever 292 ot the patent by which the side grippers can be moved in opposite directions longitudinally of the last for adjusting the upper around the last to straighten the tip seam or change the angular relation of the seam to the median line ot the shoe. rlhe shatt 10 and the rack slides are mounted in boxes 12 that can move together forwardly and backwardly and that have rack teeth on their upper faces, Fig. 2. These rack teeth are engaged by teeth on a toredrawing shatt l5 that has a depending hand lever 91 by which the side grippers can be moved together in the same direction tor adjusting the upper forwardly or backwardly. This adjustment positions the tip seam to produce a longer or a shorter tip and the toe gripper can be further updrawn or be lowerI in cooperation with the side grippers tor this same purpose it desired. r.there are yielding connections 8G, 8S, Si) and GO trom the power mechanism to the lever by which automatic toredraw can be obtained, but which do not interfere with manual toredrawing adjustment.

To the machine arranged as above described the new invention is here shown as applied. rithe trame ot the machine pivotally supports in trent of the toe gripper a swinging arm Q5 that is normally held by a spring 2G in the position indicated in dotted lines. To the lower end ot this arm 25 is adjustably secured, by a bolt Q8 and .f'ertical and horizontal slots 27, Qt), a horizontal arm 30. This arm is vforked to provide a slideway tor a bar 35 which is normally pressed outward by a spring 3G. Upon this bar is pivoted the toe end abut ment block comprising the abutment plate 40 and the angular attaching portion 42, said parts being held normally in alinement by springs 43, 43 but permitted slight movement about pivot The lateral edges of a depending portion of abutment plate 40 are embraced by a trame 4G in which is held the transparent or approximately transparent gage plate of celluloid or other suitable material. This gage plate is of suitable size to cover the top :tace ot a shoe and is preferably somewhat flexible so that it will adapt itselt' to the work as indicated in Fig. l, where it is bent by engagement with the shoe. @n the gage plate is marked a graduated scale as shown by three series of marks, one in the middle ot the toe and one at each lateral side of the middle and separated therefrom by unmarked, clear spaces through which the machine operator can get an unobstructed view of the tip seam. Conveniently the graduations into eighths, sixteenths and thirty-seconds ot an inch may be marked in different colors to facilitate ready reading ot' the measurement. The gage plate trame 4G is adjustable up and down on the toe abutment, and tor this purpose the portion which embraces the edges ot that abutment has an ear in which an adjusting screw 47 is swiveled. This screw is threaded into an ear on the abutment. rlhe trame stiifens the Celluloid plate, which is necessarily thin, and said trame has laterally projecting arms 48 by which the operator may engage it for turning the gage plate slightly to one side or tl e other on pivot 44 it required in measuring shoes on right and lett crooked lasts. At its pivotal connection with the machine trame the arm Q5 has a` hub with a ratchet tace on its rear side that is engaged by a pawl 50, Fig. l, to hold the measuring device or apparatus in its downwardly swung position and against the action of the spring 26. The pawl has a depending tripper arm 52 standing in the path of the side clamp 5 on the right hand side of the machine, which side clamp carries, for the purpose of operating the tripping device, an inclined plate 54 arranged to effect lifting of the pawl 52 when the side clamp swings into operative shoe supporting position.

In the use of the machine equipped with this invention an assembled shoe, comprising a last and innersole and upper materials preferably adjusted relatively and connected together by one or more tacks at the heel end, is presented sole face upwardly against the sole rest of the machine and the upper is positioned between the open jaws of the toe and side grippers 2 and 4. The po-wer is then applied to the cam shaft of the machine and the grippers caused to seize and updraw the upper and also foredraw it if desired, and the machine then comes to rest to permit the operator to inspect the work. He now swings the measuring device down until the toe end abut-ment is firmly pressed against the shoe as in Fig. 1. The spring 36 yields to allow this firm pressure to be obtained and to maintain it. In this position the pawl locks the measurer. The operator can now look through the gage plate 45 at the tip seam and the graduations disclose to him at a glance both the length of the tip seam and its angular relation to the shoe and he has both his handsfree for use in making such adjustments of the upper by the grippers as the measurer shows to be required. The adjustments for length can be made by the foredraw lever 91 and the toe gripper,the updraw lever of which has a handle as in said prior patent. The adjustment for length can also be made by the hand lever 160 by which the last can be moved within the upper as explained in British specification 12,304/03. Adjustment for straightening the tip seam can be made by the tip straightening lever 292. It is to be noted that these adjustments can be made while the operator watches their effect on the upper through the transparent gage plate 45 so that there is no guess work about the adjustment nor any of the cut-and-try practice followed where a hand gage is picked up from the bench and applied after each trial adjustment. The new invention enables t-he need of adjustment, if any, and its nature and extent to be seen at a glance and the adjustments to be made with no waste of time so that the daily output of the machine and the earnings of the operator are substantially increased by the use of the invention. Then the machine is restarted one of the incoming side clamps, which precedes the tackers in order to seize and hold the shoe for the fastening operation, brings the t-ripper 54 into engagement with the tripping arm 52 of pawl 50 and lifts that pawl to unlock the measuring device and allow spring 26 to swing it to the dotted line position, F ig. 1, where it is out of the way of the subsequent operations and of the presentation of the next shoe to the machine. The operator can engage the tripping arm 52 and raise the locking pawl 50 at will instead of waiting for the restarting of the machine if that is preferred in any instance.

Having explained the. nature of this invention and described a preferred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States 1.
