POSITIONING DEVICE.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed October 2, 1917. Serial No. 194,412.

To all whom it may concern:

Be it known that I, HENRY W. WINTER, a citizen of the United States, residin at Methuen, in the county of Essex and S tate of Massachusetts, have invented certain Improvementsin Positioning Devices, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawlngs indicating like parts in the several figures.

This invention concerns gaging devices for positioning work in some definite relation to an element which is to operate upon it. It more particularly relates to gages for thus determining the positions of the soles of shoes.

A purpose of the invention is to provide an arrangement whereby objects varying in two dimensionsmay be presented accurately to an operating element 'so that the operations will be performed, for example, at some predetermined distances from the margin. Conditions calling for the employment of the invention are encountered, as an instance of its application, in stamping trade marks or other inscriptions upon the soles of shoes just at the inner side of the heel breast. As soles change in length from one size to another, they change also in width, under the present practice the ratio between these variations being as four to one, since for a size the lengthdiffers from that preceding or succeeding it by one-third of an inch, while at the same time the width varies one-twelfth of an inch.

With this object in view, a feature of the invention consists of gagemembers movable in directions corresponding to the longitudinal andtransverse dimensions of objects to be gaged, this movement being effected through distances having the same ratio as the dimensions of the objects.

Still another feature relates to the capability of adjustment of at least one of the gage members to adapt the device for variations in one dimension independently of those which attend or are controlled by variations in another dimension.

These features, together with others involved in the invention, will now be described in connection with the accompany- 111% drawing, in whichigare 1 shows one form of my improved positioning device applied to a stamping machine;

Fig. 2 is a top plan view of the Work table, parts being broken away, and F F1g. 3 is a section on the line 33 of The numeral 10 designates the form of a stamping machine in connection with which apparatus I have chosen to illustrate my invention, though it is to be understood that it may be applied to other types of machine. In this frame operates a stamping head 12 movable above a table 14 for supporting the work, this work, in the present instance, consisting of the soles of shoes at the center of which, transversely, and just forward of the heel portion an inscription is to be stamped. The sole is accurately positioned.

with respect to the dies 16 carried on the head, by gage members 18 and 20. The former member provides an end gage arranged to Contact with the center of the heel end of the sole to bring the dies into contact with the desired points upon the sole, considered longitudinally. The member 20 serves asa side gage, and against this rests the side of the heel portion of the sole, fixing its position to brin the inscription at the transverse center. lhrough the table from the rear forwardly is a slot 22 through which extends the age member 18, carried by and preferably lntegral with a slide 24 situated below the table and mounted to move in ways furnished by plates 26, 26 secured to webs, cast upon the under side of the table by screws 28. The inner and upper corners of the plates 26 enter rectangular recesses in the outer edges of the slide 24 to permit said slide to be moved longitudinally of the table, that is, from the front to the rear or the reverse. At the forward side of the table is a depending lug 30 threaded to receive an actuating member for the slide 24, which may consist of a screw 32 held against longitudinal movement by engage ment of the inner side of its head 34 with a boss 36 upon the frame, the inner side of the boss contacting with a collar 38 which may be integral with the screw. The boss is slotted vertically to enable the screw 32 to be introduced into the opening in the frame.

At the upper side of the slide 24 is a projection 40, preferably in the form of a rec tangular bar, integral with the slide and being inclined at an angle to the direction of movement of the slide. Between the slide 24 and the under side of the table is located 5 a transverse slide 42 movable substantially at right angles to the direction of movement of the first: named slide in ways turnished by a slot 44 formed beneath the table. This projection 40 enters a similarly inclined angular depression l6 in the under side of the slide A2. The table is slotted transversely at 48, and through this opening projects a raised portion 50 of the slide 42. Upon the portion 50, guided by a square boss 52 entering a slot 54: in the hor zontal portion 55, is the side gage 20. This side gage may be adjusted independentlyof the end gage 18 by moving it upon its sl de 42, by virtue of the slotted connection with the boss 52, and clamped in the desired pos1-- tion by ascrew 56 threaded into the boss and having its head contacting with the horizontal portionof the gage,

The operator in using this gaging device alters the position of the end gage 18 by turning the screw32 in one direction or the other, until, when the sole to be stamped 1s in contact with said gage, the inscription will be at the proper point longitudinally of the sole. In thus shifting the end gage, its projection 40, moving through the depression 46,'by virtue of its inclination shifts the slide 42 transversely so that the side gage is simultaneously moved toward or from the side of the sole. The angle of inclination of the elements 40 and 46 is such that this latter movement is in the correct ratio of the difference between the lengths of diverse sizes to the difierence between the widths of such sizes, this being, as already stated, customarily .as four, to one. Obviously, however, within reasonable limits the inclination of theparts could be changed to give any other ratio necessary. The side gage having been given a proper initial setting by the screw 56, this will maintain the inscription always in the correct central position transversely of the sole. Thus it will be seen that for all variations in the size of-the soles they may be accurately positioned by a single actuating element. If the width changes, as well asjthesize, this is provided for by an adj ustment of the side gage through the screw 56.

Having thus described my invention, what I claim as new and desire to secure by LettersPatent of the United States is:

l. A device, for positioning objects in which longitudinal and transverse dimensions vary in accordance with a definite ratio, comprising gage members movable respectively in corresponding longitudinal and transverse directions, and means constructed and arranged for moving said members through distances having the same ratio as the dimensions of the object.
