IMPLEMENT FOR RESHAPING DISTORTED ELEVATOR BUGKETS.

of such'buckets from their supports, and a primary object is the provision of a simple inexpensive hand implement for the reshaping of elevator buckets'which have become distorted in use, for instance where the outer Walls have become bulged or indented, or where the buckets have been laterally distorted to such an extent as to require their restoration more or less to normal shape.

In the accompanying drawing which illustrates my present invention and forms a part of this specification,

Fig.1 is a perspective view. of my improved implement, a

a bucket,

Fig. 3 is a view showing the same applied to the inner surfaces of diagonally opposite corners, and o f Fig. 4 is a perspective view of the'handle, showing one of the thrust bars and one of the engaging elements.

Referring now to these figures, my invention proposes the use of a pair of thrust bars 10 and 11, of similar construction, each consisting of a straight bar, the inner end of which is provided with a longitudinal series of openings 12, and the outer end of which carries an engaging element having fiat body 13 provided at its outer end with flanges 14 joining one another at approximately right angles, the flanges extending to one side of the body 13 so that they are thus adapted for engagement with either the outer or inner faces of diametrically opposite corners of an elevator bucket indicated at 15, as shown respectively in Figures 2 and 3.

With the thrust bars 10 and 11, a handle bar 16 is utilized. This lever has a hand piece 17 at one end and adjacent to its op-- posite end is provided with a longitudinal series of openings 18. Through selected openings of the handle bar and through selected openings of the thrust bars 10 and 11, pivot pins 19 are extendedso as to adj'ustably join the thrust-bars to the lever, the thrust bars being in parallel relation with their inner ends overlapping in edge wise relation as plainly seen inv Figures 1 to 3 inclusive, and with their plvotpins 19 offset with respect to one another in therdirection of the longitudinal axis of the lever, so that upon swinging movement of the latter,'with the engaging elements applied as 1i; f.

in Figures 2 and 3, the thrust bars 10 and 11 will be shifted in the direction of their length toward and away from one another as the case may be. I Frequently the elevator buckets 15 are laterally deflected from a true rectangle, and in order to restore the, same to shape, the'imp'lement as above described, is particularly effective when used first as in Fig- 'ure 2 in connection with diametrically opposite corners, and then as in Figure 3 in ,iconnection with the other diametrically opposite corners It is obvious from the foregoing that my invention'provides a simple, strong and durable implement for the purpose described, which may be easily engaged, readily manipulated, and efiectively used in practice.

I claim 1. An implement ofthe class described including av pair 0t thrust bars movable approximately in relatively opposite directions, an actuating lever operatively connected with said thrust bars, and a workengaging element carried by one end of each thrust bar and consisting of a body having a right-angular head adapted to en gage either the inner or the outer faces of.

diagonally opposite corners of an elevator,

bucket.

2. An implement of the character d scribed including a pair of thrust bars movable in approximately parallel relation relative to one another and having their inner ends overlapping and provided with lengthwise series of apertures, an actuating lever having a handle at one end and having a lengthwise series of apertures at its opposite end, pivot bolts extending thrust bars and certain of the apertures of through certain of the apertures of said portions of the flanges of each element projecting at approximately right angles to the lever, and Work-engaging elements in- 'one another and said flanges presenting 1 eluding flat bodies connected at one end to means to engage respectively the outer or the outer ends of the thrust bars, the said inner faces of an elevator bucket;

flat hodi es of the "work engaging:e1ements ee j terminating in' ang-u-larly flzihgedlouterends, CHARLES PQDRTER.
