UNITED STATES FRANK HARRY CRANE, or CLEVELAND, OHIO.
TROLLEY-POLE ATTACHMENT.
Specification or Letters Patent.
Application filed November 23, 1910. Serial No. 593,770.
, To (Illa-P71 0171 it may concern;
Be it knownthat I, FRANK H. (lease, a citizen of the ,United States, residing at Cleveland, in, the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in 'lrollcy-lole Attachments, of which the following is a specification.
This invention relates to trolley heads, the primary object of said invention being to provide a device of this character which will accommodate itself to curves and which will always maintain a correct position relative to thetrolley stand when the wire is re moved from the wheel.
In the drawings: Figure 1 is a side elevation of the device, Fig. 2 a similar view partly in section, Fig. 3 a detail view showingthe manner of positioning the current transmitting member, Fig. 4 a section taken on the line 4--4 of Fig. 1, and Fig. a detail view of the wheel supporting member removed from the casing.
In the drawings: 10 designates a cylindrical casing which is provided with the hollow offset portion 11, said hollow offset portion being adapted to receive the end portion of a trolley pole 12. The standard 1d of the harp 15 is adapted to extend through an opening formed in the top plate 16 of the. casing. A shoulder 17 which is formed integral with the harp being adapted to rest. on a suitable wear plate 18, said wear plate and the bushing 19 being insulated from the casing by the bushing 20 and a plate 21 which are formed of hard rubber.
A U-shaped bracket member 22 is bolted to the casing at a point adjacent the extension 11. one arm of said bracket member being adapted to receive the insulated conducting wire 23. The other arm of said bracket being provided with the sleeve portion 24 through which the standard 14 extends, said standard beinginsulated from said bracket by a bushing 25 of rubber. a metallic bushing 26 being interposed between the stall and the bushing 25. Both of these bushings are provided with annular shoulders to hold the same in position. A bracket 27 is arranged diametrically opposite the bracket 22 and at a point below the same, said bracket being also bolted to the casing 10. This bracket is adapted to support the staff 14 in the same manner as the bracket 22. bushings 23 and 26' being interposed between the same and said staff. It will be seen froni'the foregoing that the two brackets form a perfect bearing for the stall" 1-1.
The reduced end portion of the statl 14,
28, is adapted to receive a bolt 29 which is.
insulated from the staff by a bushing 30 and washers 31. This "bolt is provided with the head portion 29' in which is formed a suitable aperture which is adapted to receive a member 33 which is secured to a spring 34, the other end of said spring being connected to a bracket 35 which is bolted to the casing at a point below the hollow offset 11. An annular flange 36 is formed on a staff 14, said flange preventing said stat? from rising in its bearings. A contact spring 37 is secured to the staff 14, said spring being in contact with the trolley wheel, thus forming a contact for the staff. The arm 27 is provided with the extension 27 to which is secured a contact spring 27 said spring being bolted to said extension, the bolts being properly insulated by bushings 35 and washers 35". The extension 27 extends to a point adjacent the portion 22' of the bracket 22 which supports the conductor 23, said conductor bein'gsecured to the contact bolt 39 which is carried by the contact spring 27 thus conducting the current from the spring contact 37 through the stall 14 and by means of the contact spring 27" and the conductor 23 to the controller.
The many advantages of a construction of this sort will be clearly apparent as the same will allow the trolley wheel to follow the wire at all times. In making'a turn'it will be seen that the staff will rotate to coinpe-nsate for the same and in the event of the wheel leaving the wire it will be 'seen that the spring-34 will return the wheel to its normal position through the medium of the staff.
Particular attention is called to the peculiar construction and arrangement of the brackets which support the staff as well as the manner of conducting the current to the controller.
lVhat is claimed is:
1. A trolley head consisting of a cylindrical casing. a hollow otl'set portion formed integral with said casing. said otiset portion being adapted to receive one end of the trolley pole. a bracket secured within said casing at a point adjacentthe hollow extension. a staff adapted to support atrolley wheel, a sleeve formed integral with 'said Patented May 9, 1 911. I
bracket and raped-to form armin for said staff, a second bracket arranged diametrically opposite the "first mentioned bracket, said bracket'forming a bearing for said stafl, an extension formed integral with said bracket, a contact spring on said extension, said staff being provided with a reduced-end portion, a bolt passing through said reduced end portion, a spring connected tosaid casing and bolt, said spring being arranged to normally hold the trolley .wheel in alinement with the trolley stand;
- 2. A trolleyhe'a d consist-ingot a cylindrical, casing, said casing being provided with a hollow offset, a plurality of brackets arranged w ithinisaid casing,.-a stafi' supported by said -braokets, a flange formed upon said staff, saidfiange being adapted -to engage said casing, a second flange arranged adjacent the other end of said staff, the end portion of said stafi being reduced and'resiliently connected to said casing,,.a;"conductor supported by one of said brackets and a spring contact supported by the other-"ofsaid brackets, said spring contactbeing provided with an extension adapted to receive the end portion of said conductor. In testimony whereof I afiix my signature, in the presence of two Witnesses.
