SUPPORT FOR SIGNAL-LAMP BRACKETS.
Application filed July 23,
T 0 aZZ whom it may concern Be it known that I, FRED Rare, a citizen of the United States of America, residing at Vest Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Supports for Signal-Lamp Brackets, of which the following is a specification.
My invention relates to supports for sig nal lamp brackets sum as are in general use on railroads, the object of this invention being to provide an improved supporting bracket which will have a simple, inexpensive and readily adjustable means for connecting the signal lamp bracket thereto so as to permit a limited rotating movement of the upright portion of the lamp bracket substantially as if the lower end of said portion were hinged to the horizontal portion at or near a point on the longitudinal axis thereof; and which is of such a nature that existing equipment may be reconstructed to conform thereto. with a minimum of labor and in the field.
I accomplish my object by means of a lamp bracket support and attaching means constructed as illustrated in the accompanying drawings in which:
Figure l is a plan view of a lamp bracket and my improved supporting bracket applied to a pole.
Fig. 2 is a side elevation of Fig. 1.
Fig. 3 is .a cross section along the line X-X on Fig. l.
The same reference characters refer to the same parts throughout the several views.
Referring to the drawings, A represents a portion of the usual signal standard or pole against which is fastened a saddle B, by means of the U-bolt C and nuts D, or in any other suitable manner. To the saddle B is fastened by means of suitable bolts or cap screws E, the supporting bracket F, to which the usual lamp bracket G is attached by means of bolts I-I-H.
The supporting bracket F is usually a forging, and very frequently the bend f, is found not to have been made exactly square across the bar; and although the two legs of the bracket may lie at right angles to each other. if the bend is inaccurate it will be found that the upright portion 5/, of the lamp bracket does not stand in proper alinement when the lamp bracket is bolted against the supporting bracket in the usual manner. It is then necessary to rock the Specification of Letters Patent.
Patented Nov. 22, 1921.
1921. Serial No. 486,969.
lamp bracket to the right or left and to use shims to hold it in proper position.
In my improved supporting bracket the connection is made by counter-sinking the upper surface of the supporting bracket about the holes adapted to pass the bolts H-H, (using a spherical reamer or countersink) and placing therein cupped washers I: having a formed thickness greater than the depth of the countersinks and adapted to hold the lamp bracket and supporting bracket in spaced relation to each other when the bolts HI-I are tightened. In place of the cupped washers K, I may use solid washers shaped as a spherical segment.
The opening through the cupped Washers are somewhat larger than the shank of the bolts II, and by loosening the bolts the two washers may be caused to shift in the coun tersunk holes and permit the rocking of the upright portion of the lamp bracket so as to bring it into proper alinement. Tightenin of the bolts II, II, will then hold the lamp bracket securely in such adjusted position.
As the only change which is required in existing apparatus in order to apply my improvement is the countersinking of the bolt holes in the supporting bracket, it is obvious that such change may be made in the field and with a minimum amount of labor.
I claim:
1. In a support for signal lamp brackets, a supporting member one end thereof adapted to be fastened to a standard; bolt holes in said member countersunk as with a spherical reamer; 'ashcrs shaped as spherical segments and adapted to seat in and pro ject beyond said countersunk holes; and bolts adapted to bind said supporting member and washers firmly to a signal lamp bracket.
2. The combination with a signal lamp bracket, of a supporting member one end thereof adapted to be fastened to a standard; bolt holes in said supporting member, said holes countersunk; washers shaped as spherical segments and adapted to seat in and project beyond said countersunk holes; and bolts adapted to bind said signal lamp bracket, said supporting member and said washers firmly together.
In testimony whereof I have affixed my signature.
FRED RAPP.
