COLLECTOR FOR TRAVELING CRANES AND THE LIKE Specification of Letters Patent.
Patented Nov. 14, 1911.
To all whom it may concern:
Be it known that I, ERIC L. HOOFRING, of Vandergrift, Westmoreland county, Pennsylvania, have invented a new and useful Collector for Traveling Cranes and the Like, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part ,of this specification, in which- Figure l is a perspective view of a collector embodying my invention; Fig. 2 is an end view of the same; Fig. 3 is a plan view and Fig. 4 is a similar view, on a smaller scale, showing a modification.
My invention has relation to current collectors for traveling cranes and the like, and is designed to provide a simple and eflicient device of this character in which the part which contacts with the wire and is most subject to wear, can be readily re.
moved and renewed without disconnecting the collector as a whole and without detaching the feed wire leading to the crane motor or motors. In the preferred form of my invention I also provide the collector with guard means to prevent it from leaving the wire.
The nature of my invention will be best understood by reference to the accompanying drawings, in which I have shown two embodiments of my invention, and which will now be described, it being premised, however, that the details of construction and arrangement can be changed in many respects without departing from the spirit and scope of my invention as defined in the claims.
Referring to the form of my invention as shown in Figs. 1, 2 and 3, the numeral 2 designates a sleeve or socket portion, which is formed in two sections, secured together by the bolts 2 and which is designed to be clamped to a suitable arm or bar on the traveling crane. This portion of the device may be of any desired construction which will provide for the ready and convenient attachment of the device to a crane.
The forward section of the sleeve or socket 2 is provided with the projection 3 carrying the portion l which has two or more projecting studs or pins 5 for the collector shoe 6. This shoe consists of a more or less elongated bar or body having a longitudinal groove 7 in its upper face to re ceive the trolley wire or conductor and also having at its central portion the upwardly extending parallel guard flanges 8. These guard flanges are formed with registering perforations to engage the pins or studs 5, the shoe being secured on these pins in any suitable manner, as by means of the cotter pins 9.
It will be readily seen that when the shoe 6 becomes worn it can readily be detached by removing the cotter pins 9 and a new one supplied without disconnecting the device as a whole from the crane, and without disconnecting the feed wire 10 which is secured in the projecting lug 11 by means of a set screw 12 or other suitable device. The flanges 8 together with the pins or studs 5 act as guards to effectively prevent the shoe from leaving the trolley wire.
In the modification shown in Fig. 4E, instead of the elongated shoe 6, grooved collector wheels 13 are journaled on the pins or studs 5*. These wheels when worn can be readily removed and replaced by new ones.
What I claim is:
1. A device of the character described comprisng a sleeve or socket portion formed in two sections, one of said sections having a forward projection, and said projection having forwardly projecting studs, and an elongated grooved collector bar det-achably secured to said studs, the studs extending transversely across the groove and forming guards, substantially as described.
2. A device of the character described, comprising a split socket portion having a lateral horizontal projection and said projection having two studs extending horizontally therefrom, and current-collecting means mounted on said studs, at least one of said studs being above the conductor which is engaged by the collecting means, said means comprising a grooved member to engage the underside of the collector, substantially as described.
In testimony whereof, I have hereunto set my hand.
nnro L. HOOFRING.
