Application filed um 25, 1920, Seria1j1Io';'368, 529." Renewed November 29,1920. Serial No. 427,204.
To allwhom it may concern:
Be" it known that 1, CHARLES. A. 'DUNHAM, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota,'have invented certain new and useful Improvements in Adjustable Detector-Bar Supports, of which' the following is a specification.
My invention relates to supports for detector bars used in connection with railway switches, and has for an object the provision of asupport which is capable of simultaneous vertical and'lat'eral adjustment.
I will describe one form of detector'bar support embodying'my invention, and will then point out the novel features thereof in claims. I
In the accompanying drawings, Figurel is a view showing in front elevation a portion of arailway rail,'a portion of a detector bar, and'one form of detector bar support embodying my invention." Fig. 2 is a view similar to Fig. 1 but with certain parts re moved. Fig. 3 is'a sectional view on the line III- 111 of Fig. 11' looking in the direction ofthe arrows. Fig; 4'is a view showing in frontelevation a block 24 forming part of the support shownin the preceding views.
Fig. 5 'is "a side view of the block 24 shown inFig.4.fl Similar reference characters refer to simi lar p'arts'in' each of the several views.
Referring first to Figs. land 3, the reference character 14 designates a track rail of a railway track. Located atone side of this rail is a detector bar'8which is supported on a roller 32 mounted in a bracket 10. This detector bar is provided with amotionplate 7 by-virtue ofv which longitudinal movement of the bar causes the bar to move upwardly beyond'the top of a track rail 14. 7
Located adjacent one of the base flanges of the rail 14 is a member 12, which is attached to the base of the rail in a suitable manner, such, for example, by bolts 16, the ends of which are bent to form hooks 16 adapted to engage the opposite base flange of the rail. The member 12 is attached to the bolts 16 by means of nuts 16. The
A bolt 40 passesthrough these two slots and through a h0le19, in the arm 20, this bolt being provided with a nut 42 and a suitable nut-locking device 44. It will'be seen that by tightening the nut 42 the bracket 10 and the block 24 are rigidly secured to" the bracket12.
It will be observed that the vertical position'of the bracket 10, and, consequently, of the detector bar 8 may be varied by moving the bracket '10 upwardly and downwardly on the outer surface of the adjusting block 24, it being necessary only to loosen the nut 42 to accomplish this adjustment. Further- 'more, it will be observed that the vertical and lateral position of the bracket 10 and the detector bar 8 withrespect 'to the track rail 14 may be simultaneously varied by moving the block 24 upwardly and downwardly with respect to the member'12, the
block 24and the bracket 10 being retained in fixed relative positions during this adjustment.
The concaved surface on the member 12 and the convexed surface on the block 24 may be so designed that the movement of the bloclrwith respect to the member will provide the necessary adjustment to locate the detector bar 8 in the proper position for track rails of various standard shapes and 7 sizes. 1
Other advantages of a structure embodying my invention are that the design is compact, the necessity for havingthe adjusting block extend down into the gravel ballast is avoided, and a uniform and continuous bearing is provided on both sides of the adjusting block to insure rigidity of the parts after adjustment.
Although I have herein shown and described only one form of detector bar sup-' port embodying my invention, it is understood that various changes and modifications may be made therein within the scope of the appended claims without departing from V the spirit and scope of my invention.
Having thus described my invention, what I claim is:
1. A support for a railway detector bar comprising a member fixed to a rail, a block having an inner surface adapted to cooperate with the outer surface of said member for upward and downward movement thereover, one of said surfaces being concaved and the other being convexed, a bracket supported by said block, and means for securing said block to said'member in adjusted position.
. 2. A supportfor a railway detector bar comprising a member fixed to a. rail, the outer surface of said member being concaved, a block having a convexed surface adapted to cooperate with said concaved surface for upward and downward movement thereover, a bracket supported by said block,-
and means for securing said block to said member in adjusted position. p
3.-A support for a railway detector bar 4 comprising a member fixed to a rail, the
concaved surface for upward and downward movement thereover, said block being provided with a vertically disposed slot, a bracket having a shank portion in engagement with the outer surface of said block, said shank being provided with a vera tically-disposed slot, and 'a bolt extending through both of said slots for securing said block and said shank in adjusted position.
5. A support for a railway detector bar comprising a member attached to..a' track rail and having an outer concaved face, and
a detector bar bracket including apart movable therewith and having a convexed surwith the concaved surface,
face cooperating on said member. a a
6. A support for a railway detector bar comprising a'member' attached to a track rail and having an outer concaved face provided with horizontal teeth, a block having an inner convexed surface provided with teeth cooperating with the teeth on said 7 member; a bracket supported by said block,
and means for securing said member, block and brackettogether I i A support for a railway detector bar comprising a member attached to a track rail, a detector bar bracket, and a block interposed between said member and said bracket and having a curved surface cooperating with a curved surface on said member whereby up and down movements of said bracket and said block as aunit will cause simultaneous verticaland lateral adjustment of the bracket with respect to said member.
8. A support fora railway detectorbar comprising a memberattached td'a track I rail, a detector bar. bracket, and means inter'posed between' said member and said bracket and including two cooperating curved surfaces for permitting'simultaneous vertical and lateral "adjustment of the bracket with respect to the rail.
In testimony whereof Iafiix my si nature.
