IMECEANISIM FOR HOLDING OR TRANSFEBEING- ARTICLES.

Application filed November 21, 1919, Serial No. 339,615.

To aZZ w 710m it may concern Be it known that I, FREDERICK M. Foiusnn, a citizen of the United States, residing at Revere, in the county of Suffolk and State of lviassachusetts, have invented certain Improvements in Mechanism for Holding or transferring Articles, of which the following description, in connection with the accompanying drawings, is a specification, like reference Cl'1i1dCtQ1S on the drawings indicating parts in the several figures.

This invention relates to a mechanism or apparatus for holding or trans'jc ring articles which in the illustrated embodiment is particularly designed for use in the manufacture ol shoes for picking up pieces of material one at a time and transferring them to a desired location. However, it will be obvious that the invention is capable of wide application.

The primary object of the inventionis to produce a novel mechanism of the character above indicated which will be simple, eliicient and reliable in construction and in operation.

With this and other objects in view, the invention comprises in one aspect the combination of a support, a member movable therein and constructed and arranged to engage an article for example a sole or a part ofa shoe bottom, and another member constructed and arranged to be brought into operative engagement with said article by relative movement of the support and said first inember. Furthermore, the invention comprises cer'ain other combinations and arrangements of parts, as well various details of.

construction, which will be set forth in the following description of a preferred embodiment thereof and willthcu be pointed out in the appended claims.

Referring to the accompanying drawings,

Fig. 1 shows in side elevationan article holding or transferring mechanism embody ing the invention, the mechanism being shown in a position in which one of its three article engaging members has been brought into operative engagement with the forepart ot' a shoe bottom;

Fig. 2 is a view in rear elevation partly in section showing the lower portion of the same mechanism after all three of such Renewed April 20, 1922. Serial No. 555,695.

members have been brought into final operative engagement with the article;

Fig. 3 is a sectional plan along the line .lllflll, Fig. 2, the outline of the sole portion of the shoe bottom being shown in. broken lines; and I Fig. l is a sectional detail along the line IV IV, Fig. 1. I

The mechanism herein shown by way of illustration as embodying the invention has been particularly designed for use as a unit in an automatic, machine which applicant has invented for making shoe bottoms such as are disclosed in his application for U. S. Patent Ser. No. 203,802, filed November 4, 1917, the particular mechanism herein shown being employed to remove molded shoe bottom foreparts, each consisting of a sole and certain other parts secured thereto from the carriers of such a machine by which they are assembled and delivering them into a box or holder, all as fully disclosed in still another application Ser. No. 477,709, filed by the present applicant June 15, 1921. l-lowever, the mechanism shown here'in may also be employed as a tool supported in and operated by the hand and, therefore, the means for supporting and operating the mechanism forms no part of the present invention and will not be described herein. Moreover, obviously the mechanism shown may be used for handling articles and blanks of numerous other kinds than that abovementioned.

. As illustrated in the drawings, the article to be transferred is a shoe bottom forepart comprising a short sole 2 and a sheet filler 4 secured thereto. Preferably a steel shank piece (not shown) will lie between these parts 2 and 4. As shown in Figl, the article lies upon a support or mold 6, the upper surface of which is recessed at 8 to permit the lips of the arms hereinafter described to swingbeneath thelower face of the article. The holding or transferring mechanism itself, which may conveniently be referred to as a picker, includes a support 10 which may be sustained and moved by any suitable mechanical means, such as two arms one of which is indicated at 12', or the upper end of the supportmay be formed as a handle ii": the device is to be used'as a hand tool. A vertical sleeve 14: is mounted to slide in the lower end of the support and has at its lower end a fixed cross bar 16 while at its upper end is clamped a block 18. A spring 20 interposed between the lower end of the support 10 and the upper face of cross bar 16 tends to hold the block 18 against the support 10 with a considerable degree of pressure but allows the sleeve and its connected parts to yield upward with relation to the support. I

A rod 24: is mounted to slide in the sleeve 14 and has secured at its lower end a cross bar 26 from which projects downward a boss 28 having in its lower face a stab point 30. A spring 32 substantially lighter than the spring 20 is interposed between the cross bar 26 and the end wall of a socket 34; in the cross bar 16. A sleeve 36 having a tapering upper face 37 and a shoulder 38 is se cured to the upper end of rod 24.

A pair of arms 4L0 bifurcated at their inner ends carry fingers 42 at their outer ends, each having an inturned lip it at its lower end and being adjust-ably secured by a set screw 46 in the outer end of its arm 40. Each arm 40 is clamped to a pivot pin 48 journaled in the cross bar 26, the upper end of each pin being formed with a relatively steep screw 50 threaded into the cross bar 16. Pivoted upon a bracket 5a extending upward from the lower part ofsupport 10 is a bell crank lever 56 having upon one of its arms a hook or latch 58 adapted to slide over the tapered surface 37 and-engagethe shoulder 38 of sleeve 36 when the latter rises. A link 60 connects the lever 56 with another lever 62 pivoted upon the support 10 while the opposite end of lever 62 is provided with an adjustable stop 64. A sprin 66 tends constantly to swing the hook 58 inward into position for latching under the shoulder 38.

The sleeve 14 with the parts carried thereby may be locked in one of a plurality of angular positions, particularly to accommodate right and left shoe bottom foreparts,

by means of a pin 68 projecting downward from block 18 and constructed and arranged to engage either'of' two holes 70 (see Figs. 1 and 4-) in the support.

The manner in which the mechanism described may be used for picking up and transferring articles will be readily understood. For example the mechanism maybe used to pickup shoe bottom foreparts 2, l from the mold 6 and to transfer them to a position over abox into which they ma-ylie allowed to drop. Theaction of sprmg;

tends to maintain the fingers; relatively far apartthat is, open'with the block 18 resting against support IOanCl sleeve 36'" resting against the block. This open position of themechanism is illustrated in l where, however, the mechanism is shown as having been brought downward so that the boss 28 is firmly in contact with the upper face of the shoe bottom with the stab point SOpenetrating the same, sleeve 14: and rod 24c being preferably substantially in vertical position. Thereupon downward pressure exerted upon the support 10, compresses spring 32 and moves the cross bar 26 with its connected parts, including screws 50. upward with relation to the cross bar 16. Through the co-action of the screws with the threaded portions of the bar, the arms 40 are swung inward and the lips 44 enter the recess 8' in the mold and engage the lower face of the sole adjacent its opposite edges, and in the region of its ball line but somewhat to the rear, as shown in Figs. 2 and 3. The inward movement of the arms is limited by the engagement of the upper face of the bar 26 with the lower face of the bar16 and the lips 44 are of such length that they can be used, without substitution of different fingers, as, for soles of different widths. Should the downward movement of support 10 continue. it will be taken up by the yielding of spring 20. As the arms 40 reach their inmost or closed position shown. in Fig. 2, the latch 58 snaps beneath the shoulder 38 and maintains the lips 44c beneath the sole so that upon the upward movement of the support 10 and the other parts of the picker the article will. be carried therewith since the article is engaged relatively near its rear end, leaving the greater part of its weight forward of the lips 44. /Vhen the article has been moved to the desired point, it may bereleased quickly by the engagement of stop 64 with any suitable abutment, or the lever 62 may be moved by hand to secure the same result, so that the arms are swung to open. position through the expansion of spring 32.

It will be noted that a characteristic feature of the mechanism described is that, after the article engaging member 28' comes into contact with one face of the article, the

further movement of the support 10 rela-.

of the sleeve 14 because of the different shapes ofv right and left soles or. shoe bottoms.

Having thus indicated the nature and lessees s'Ope of the inve on and having described in detail a mechanism in which it be embodied, what I claim as new and desire to secure by Letters Patent of the United States is:
