Application filed August 27, 1921, Serial No. 496,100. Renewed January 13, 1826.
(GRANTED UNDER THE PRQ'VISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)
To all whom it may concern:
Be it known that I, HEINRICH Jnrr, a citizen of the German Republic, residing at- 1 Nuremberg, Germany, have invented certain 5 new and useful Improvements in Collectors (for which I have filed applications in Germany, June 17, 1918, Patent No. 315,436;
in Japan, September 8, 1920; in France,
July 10, 1920; in Belgium, July 9, 1920; in Poland, July 6, 1920; and in Czechoslovakia, July 2, 1920), of which the following-is a specification.
My invention relates to improvements in collectors of the Siemens bow type, and more particularly in collectors of the class which are provided with carbon shoes disposed in position for making contact with the overhead conductor, and one of the objects of the improvements is to provide a collector in which the wear is reduced to a minimum. lVith this object in view my invention consists in constructing the carbon shoe or shoes so as to lie all around the metallic part of the collector so that it is not possible that the said metallic part makes contact with the conductor. In order to reduce the wear of the carbon shoes I construct the same in such a way that independently of the height of the conductor and the inclination of the collector a broad contact is insured between the shoe and the conductor, for which purpose the carbon shoe is rotatably mounted on the metallic part of the collector and constructed with polygonal cross-section.
In order that the invention be more clearly understood an example embodying the same has been shown in the accompanying drawing, in which the same reference characters have been used in all the views to indicate corresponding parts. In said drawing7 Fig. 1, is an end view of one or" the sectional carbon shoes,
Fig. 2, is a partial side view of the improved collector,
Fig. 3, is a longitudinal section of Fig. 2,
Fig. 4, is a cross-section taken on the line AA of Fig. 3, and
Fig. 5, is a detail view showing a spring interposed between the body of the collector and the rotatable member carrying the Cal'- sh e In the example shown in the drawing, my improved collector consists of a pair of upright arms 2' (only one of which is shown in Figs. 2 and 3), each having a block 6 secured thereto, and a horizontal and straight tubular rod (Z secured with its ends to the blocks 6 and connecting the arms 2'. On the rod d a tubular rod a is rotatably mounted which is secured at its ends to metallic blocks Z. The rod (1 provides a support for carbon shoes h of polygonal and preferably triangular cross-section confined between the blocks Z and in contact therewith, and in order to hold the shoes in position relatively to each other the rod a is formed with a rib 6 made for example from wire welded to the rod, and the shoes are formed with corresponding grooves c.
The abutting faces of the blocks 6 and Z are formed with annular grooves 7 adapted to receive an open annular spring 9 having the function to put the sections of the collector under tension and to yieldingly hold the blocks Z, the rod a and the carbon shoes mounted thereon in position. The strength of the spring is such that a certain pressure of the overhead conductor on the carbon shoes or a blow of the shoes on an obstruction is necessary to turn the shoes.
The operation of the collector will readily be understood. Normally, the shoe It will make broad contact with the overhead condoctor with one of its faces, so that its wear is low. It now the conductor runs comparatively low, for examplewhen the track passes below a railroad crossing, the rod a is turned on the rod (Z and the broad contact between the conductor and the shoe is maintained. Should the shoe meetan obstruction the shoe is sometimes turned so far that the next side face makes contact with the conductor. It is not possible under any circumstances that the conductor makes contact with a metallic part of the collector. Should the engineer find that one of the faces is worn more than the other ones he can easily turn the shoe in order to insure a uniform wear.
I For these reasons the life of the collector shoe is comparatively long.

8. A. collector, comprising a rod, a tubular carbon shoe surrounding said rod and rotatable thereon, and a friction spring disposed between said rod and shoe to yieldngly hold the shoe in position.
9. A collector comprising a bow having its horizontal portion provided by a straight rod, a tubular member rotatably mounted on said rod, a carbon shoe mounted on said tubular member, and a spring frictiomillr engaging said tubular member and bow.
10. It collector of the bow type, comprising a pair ot upright arms each having a block secured to its end. a rod conuectini said blocks, a. tubular member provided at each of its ends with a block and rotatabl mounted on said rod, said bloclzs on the arms and tubular member being formed with corresponding annular grooves, annular springs disposed within said grooves and frictionall v engaging the blocks on the arms and tubular member, and a carbon shoe mounted on said tubular member.
11. A collector comprising a metallic support. relatively long and narrow structure rotatably mounted on said support. and a carbon contact covering said structure all the way round.
12. A. collector of the bow typo cmnprising a metallic support, relativelv long and narrow structure rotatably mounted on said support, and a carbon contact covering said structure all the way round and tast thereto. it A. collector comprising a metallic sup port having a supporting rod, a tube rotatabl mounted on said rod, and a carbon contact covering said tube all the way round and rotatalile therewith. said rod extending within the carbon corered part ol said tube.
