0. A. LIEB. TROLLEY EAR.
(No Model.)
No 522,844. Patented July 10 1894.
M WW UNITED STATES PATENT OFFICE.
CHARLES A. LIEB, OF NEW YORK, N. Y., ASSIGNOR TO THE GENERAL ELECTRIC COMPANY, OE BOSTON, MASSACHUSETTS.
TROLLEY-EAR.
SPECIFICATION forming part of Letterslatent No. 522,844, dated July 10, 1894.
Application filed April 12, 1894. Serial No, 507,244. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES A. LIEB, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Trolley-Ears, of which the following is a specification.
My invention relates to trolley ears, or appliances designed to support the trolley wire either from a span wire or from a bracket, and has forits object to provide a cheap and efficient construction; to which end I form the body of the ear of sheet metal with an upwardly-extending fold or fin riveted to a cast metal part.
The accompanying drawings show an embodiment of my invention, wherein- Figure 1 is a side elevation; Fig. 2 a section upon the line 2-2 of Fig. 1, of my improved trolley ear.
A is a cast metal part or bolt-portion provided with a bolt-hole E for attachment to the bracket arm or span wire.
13 is a sheet metal portion which, as shown best in Fig. 2, is formed with an upwardlyextending fin or fold B and with two ears C, C, adapted to fold around a trolley wire and hold it in place; the interior portion of the sleeve is provided with a coating of solder, as commonly used in such constructions.
A, A, 850., are the rivets.
To assemble the ear the part B is first stamped out and then pressed into shape, having a fin B made as shown in Fig. 1; the portion 13 is then inserted in the slot of the part A, holes previously being provided for the rivets A, &c., which are then inserted, and by a proper rivet punch the heads can be upset at a single operation, if desired.
What I claim as new, and desire to secure by Letters Patent of the United States, is-
1. As a new article of manufacture, a trolley ear having a sheet metal portion with an upwardly-extending fin or fold and a cast metal bolt-portion secured to the fin or fold.
2. As a new article of manufacture, an improved trolley ear, comprising a sheet metal part B, an upwardly-extending fin or fold B, a cast metal bolt-portion A, and rivets A, A, &c., securing the sheet metal part to the cast metal part.
In witness whereof I have hereunto set my hand this 10th day of April, 1894.
CHARLES A. LIEB.
