SAMUEL S. MATTHES, OF MANSFIELD, OHIO, ASSIGNOR TO THE OHIO BRASS COM- PANY, 0F MANSFIELD, OHIO, A CORPORATION OF NEW JERSEY.
METHOD OF LIANUFACTURING TROLLEY-WIRE SUPPORTS.
Appflication filed August 30, 1923. Serial No. 660,221.
To all whom it may concern:
Be it known that I, SAMUEL S. MATTHns, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Methods of Manufacturing Trolley-Tire Supports, of which the following is a specification.
My invention relates to the method of constructing conductor supports and has particular reference to that class of supports adapted to engage and secure the trolley wire to a hanger or other support.
The object of my invention is to produce a device of the class described which will be simple, strong, and economical as to cost of production.
My invention resides in the method of producing the device herein described, as set forth in the various steps.
In the drawing accompanying specification Fig. 1 shows a side plan view of a device constructed as described.
Fig. 2 is an end view in elevation of Fig. 1.
Fig. 3 is a sectional view of Fig. 1 on the line 33.
Fig. 4 .is a side plan View of the upper supporting element of Fig. 1.
In the preferred form of a device embodying my invention, I employ two members, namely: an upper supporting member 1 and a lower supporting member 2. I prefer to make the member 1 of malleable cast iron or of an iron forging in order to reduce the cost of material used in the member 1. The member 2 is invariably made of copper or some copper base alloy, and for that reason, is the expensive element of the device.
The upper supporting member 1 is divided with a boss member 3, which is recessed and internally threaded as indicated at 1, in order to provide means for securing the device to an overhead hanger. The member 1 is also provided with diametrically opposite projecting arms 5-5 and each arm is provided at its end with an aperture 6.
The lower supporting member 2 is divided with a longitudinally extending channel or groove 7 formed by the depending lips 88 and which are cast open as indicated by this the dotted lines 8 in Fig. 3 and adapted to be formed above the conductor 9 after the same has been positioned within the groove 7 as shown in Fig. 3. The member 1 is also provided with upstanding securing members l010 which co-operate with the extreme ends of the members 5 on the member 1 to unite the members 1 and 2 into a unitary device.
' In the method of constructing my invention, I first produce the member 1 by any of the well known methods for such operations, as by casting of malleable cast iron or drop forging from iron or steel. The member 1 is then placed in a mold having a recess therein which conforms to the complete device, the member 1 being placed in that portion of the recess which conforms to its shape. The balance of the recess is then filled with molten copper or copper base metal, preferably at a high temperature, and this forms the lower supporting member 2 and simultaneously unites it to the upper supporting member 1. I find that it is advisable under some conditions to have the member 1 heated at the time the member 2 is formed from the molten metal and I have also found that under some conditions, there is an advantage in having the exposed faces of the member 1 which are engaged by the molten copper or bronze covered with a metal of lower melting point than that of member 1 and such covering metal may be a low melting spelter or brazing metal such as a mixture of copper and zinc and well known in the arts, or the coating metal may be of tin which has been thoroughly applied to the exposed engaging surfaces of the member 1. The coating metal may be applied in various ways, as by the oxy-acetylene process, electric arc process or by dipping in the molten coating metal. The aperture 6 permits the molten copper or bronze to form a positive lock with the member 1. The parts after being removed from the mold will have the members 1010 dropped to cause them under some conditions to make better and more secure engagement with the arms 5-5 and this is advisable where the ends of the arms 55 have not been coated as previously described.
There are, of course, variations which may be made in my method of construction which will suggest themselves to those skilled in the art, especially variations as to the method of uniting the parts together, but such "ariations may fall within the scope oi my invention.
The member 3 may be recessed and threaded prior to or after the members 1 and 2 have been secured together.
1, find that the method of constructing an ear as above described produces a device which is very strong and economical and reliable in service.
I claim:
1. A trolley wire supporting device comprising two supporting; members, one to engage and support a trolley Wire and the other to engage and support the first mem her. the members being cast together.
2. A trolley wire supporting device comprising a member of malleable iron to secure the device to a support and a bronze member interlocked and cast therewith to engage and support the trolley wire.
3. A. trolley wire SHPpOFtillg' device comprising a member of malleable iron to secure the device to a support, recesses formed tliereim and a bronze member to support a conductor interlocked with the recesses of the first member by being cast therewith.
l. A trolley wire supporting device com prising a malleable iron member to secure the device to a support, recesses formed therein, and a bronze member to engage and support a conductor interlocked therewith and the metal of the bronze member continuous through the recesses.
In testimony whereof I afiix my signature.
