Description
Sept. 13, 1932. ApH. RENSHAW ADJUSTABLE SUPPORT FOR PIPE CARRIERS Filed April 16, 1925 a. 2 INVEZTOR.
fie} A'T R EY Patented Sept. 13, 1932 ATENT OFF-ICE ALFRED H. RENSHAW, OF N OROTON, CONNECTICUT, ASSIGNOR TO GENERAL RAILWAY l -I SIGNAL COMPANY, OF-ROCHESTER, NEW YORK Application filed April 16,1925. Serial No. 23,552;
This invention relates to an anchorage or supportfor pipe carriers of the type used to carry movable operating rods for railway switches, signals and like apparatus.
In operating outlying switches and signals from a centralized tower or station house, movable rods or pipes are often used to transmit the power from the operating lever to the switch or signal mechanism. It is customary to support these movable operating rods or pipes on a standardized type of pipe carrier having anti-friction rollers, these carriers being located at suitably spaced points along the operating rods. In locating and supporting the pipe carriers it is essential that the supporting structure be permanent, thatthe pipe carriers may be readily and quickly aligned and that the parts constituting the supporting structure be light, inexpensive and interchangeable.
In accordance with the present invention, which is a continuation in part, for all the subject matter in common, of the invention disclosed in my previous application, Ser. No.
617,628, filed February 7, 1923, it is proposed to provide a supporting structure for securing pipe carries to a permanent foundation or base block, and more specifically it is proposed to provide a structure of this type 1 which may be quickly and permanently mounted, which will permit the easy alignment of several pipe carriers as a unit, which is inexpensive and light in weight and in which the parts are readily interchangeable.
Other specific features, objects and advan: tages of the present invention will be pointed out or willbecome apparent as the description thereof progresses.
In describing the invention in detail, reference will be made to the accompanying drawing in which Fig. 1 shows a side elevation of the pipe carrier supporting structure embodying the present invention, together with a founda: tion block and two pipe carriers with the operating rods or pipes carried thereby; and
Fig. 2 is an end view of the structure shown in Fig. 1. p
Referring to the. drawing, a foundation block 1. preferably made of concrete orother suitable material, has been shown, this block shown secured to the foundation block by means of the supports comprised in the pres ent invention, and as these pipe carriers are well known to those skilled in the art, their construction will not be described in detail.
As shown, the pipe carriers consist of the 7.
Referring now more particularly to the supporting means comprising the presentinvention, two supporting pedestals 13 having wide substantially U-shaped depressions in their upper faces are placed near the ends of the foundation block 1. The pedestals 13 have enlarged separated bases or legs 14 having an opening therebetween as shown, so that they may maintain their positions on the foundation block without danger of tilting or sliding. Two grooves or notches 15 are provided at the extreme ends of the depressions in the upper faces of the pedestals, these grooves being shaped to receive the pipes 10. V
In assembling-the structure described, the foundation blocks are set along the trackway in aligned relation and at suitably spaced points. T'wo pedestals 13 are then placed near the ends of a foundation block, with the clamp pieces G passed between their bases or legs 14. The lateral pipes 10 are then passed'into the grooves 15 ofthe pedestals 13,'the clamp pieces'C being lifted to engage the'upper surfaces of these pipes 10. The threaded ends of the anchor bolts 4 are passed through the slots 17 -of the clamp pieces C and the lower ends of the'bolts 4 are inserted in the holes 2 in the foundation block. The required number of pipe carriers P may now be secured to the lateral pipes 10 by means of the hook bolts 11, and when these pipe carriers are secured'in place, the structure including the pipe carriers P and the pipes 10 may be adjusted for alignment along the operating rods 8, the pipes 10' being shifted on the pedestals '13 until the proper alignment is secured. The clamping operation is completed by tightening the nuts 18 on the anchor bolts 4, thus-securely clampingthe pipes 10 against the pedestals l3 and also clamping the pedestals 13 against the foundation block 1.
Although only one specific manner of asse'mbling the pipe carrier supporting structure of the present invention has been described. It should be understood that this assembling may be done in any one of several convenient ways. For instance, the pipe carriers P may be clamped to the pipes 10 by meansof the hookbolts 11 and transported to the foundation blocks as'a unitary structure, thepedestals 13 and the clamp pieces C being slipped over the'ends of the pipes 10 and secured to the foundation block as before.
, lVhen this procedure is followed, the pipe carriers must be removed from the ends of the pipes 10 to allow the pedestals 13 and clamp pieces C to be passed over the pipes 10.
It is sometimes desirable to assemble the entire structure including the pipe carriers on the foundation block 1 at the railway stop or other convenient point, and to subsequently set theassembled structures in place. WVith the construction of the present invention this may be very conveniently done, as
the entire-structure may be held by the ends of the lateral pipes 10 while the foundation block l is tamped into place in the ground.
It will be seen from the description given that a very convenient, simple and rugged support for pipe carriers has been provided. It should be particularly noted that the structures shown permits the use of short sections of'scrap pipe for the lateral members 10,- irregularities and variations in the diameter of these pipes being compensated r used at the outer edge of each foundation block. Asthe nut 18 of thehook bolt 4 engages the clamp piece C near its outer end, the effect of the cl-amppiece is to bend the lateral pipes 10 about the-pedestal 13 as a fulcrum-thus tendingto how the pipes 10 upwa'rdly at their midpoints and to prevent their sagging between the two foundation blocks.
Another particular advantage of the present invention resides in the fact that the parts used at each end of the foundation block are identical and hence interchangeable, this feature serving to reduce the number of different parts which must be kept in stock.
As the present invention has been described in connection with a rat-her specific clamping structure, it should be clearly understood that the invention is not limited in its scope to the exact details of the-form shown, and further, that certain alterations, changes and improvements may be made without departing from the scope of the invention-as defined by the appended claims.
