lADJUSTABLE SWITCH-ROD..

SPECIFICATION forming part of Letters Patent No. 755,471, dated March 22, 1904.

Application led January 9, 1904.

To all whom it may concern.

Be it known that I, HENRY ELLIOT, J r., a

citizen of the United States, residing in the city of St. Louis, in .the State ci' Missouri, have invented certain new and useful Improvements in Adjustable Switch-Rods, of which the following is a full, clear, and exact description, 'reference being had to the accompanying drawings, forming part of this speciiication. My invention relates to that class of adjustable switch-rods that employs an eccentric for adjusting the length oi the rod so that the switch-points may at all times be held up securely against the track-rails.

The object of my invention is to provide a device of this character which is inexpensive, which can be easily and quickly adjusted, and which is not likely to become disarranged by the rough usage to which such things are subjected. v

Figure I is a top or plan view showing my improved adjustable switch-rod. Fig. II is a section taken on line II II, Fig. I. Fig. III is an enlarged detail vertical section showing one of the eccentrics and its associated parts. Fig. IV is a perspective view of one or' the eccentrics. Fig. V isa perspective view of one of the brackets.

Referring to the drawings, 1 represents track-rails, and 2 switch-points.

3 is a switch rod or bar passing, as usual, beneath the track-rails and to which the switchpoints are connected. This connection between the switch-points and the rod or bar is effected by means oi' brackets 4, bolted at their outer ends to the webs of the switch-points and resting at their inner ends against the upper face of the switch-bar. The inner ends of the brackets have circular openings 5, in which fit disks 6, having eccentrically-located non-circular peri'orations 7. These disks will be hereinafter'referred to as eccentrica inasmuch as they so act in operation.

8 represents straps riveted to the bar 3 and which are formed to overhang the inner ends of the brackets 4, as shown in the drawings, the inner ends of the brackets thus fitting between the straps and the switch-bar.

9 represents bolts that pass through the Serial No. 188,393. (No model.)

straps 8, eccentries 6, and the switch-bar 3, the non-circular heads of these bolts fitting in correspondingly shaped enlargements of the holes in the straps 8. The portions 10 of the bolts that fit in the perforations 11 of the straps 8 are circular, and the portions 12 of the bolts that t in the perforations 13 of the switch-bar are also circular. The central portions 14 of the bolts are non-circular and correspond in shape to the openings 7, formed in the eccentrics, and I prefer to make these non-circular portions 14 somewhat longer than the thickness of the eccentries and to form enlargements in the upper portions of the holes 13 to receive the lower ends of these portions 14. The lower ends oi' the bolts 9 are provided with nuts 15 and keys 16. When it becomes necessary to adjust the switchpoints so that they will fit snugly up against the heads of the track-rails, the nuts 15 and keys 16 are removed and the bolts raised until their heads are elevated above the enlargements of the holes 11. A wrench being then applied to the bolts, the latter are turned, which will cause the .eccentrics 6 to be turned in the holes 5, and this will effect an inward or outward movement of the brackets 4 and cause the switch-points to be thrown farther apart or nearer together, as may be required. Vhen the eccentrics have thus been adjusted, the bolts are lowered again until their noncircular heads it in the enlargements of the holes 11, and the bolts, together with the eccentrics, will thus be held to their adjustment. The nuts 15 and keys 16 are now replaced in position, and the brackets will be iirmly and securely held to the switch-bar. By making the non-circular portions 14 of the bolts somewhat longer than the thickness of the eccentries these parts oi' the bolts are not likely to be moved upwardly out of the holes 7 when the bolts are raised to make an adjustment.

The device is inexpensive, is not likely to get out of order, and can be readily and effectively worked by any person of ordinary intelligence without requiring special instructions or exercising special care or attention to the work.

I claim as my invention- 1. In an adjustable switch-rod, the combi- IOO nation of a bar, brackets secured to the sWitchl points and resting upon the bar, eccentrics fitting in holes formed in the brackets, straps secured to the switch-bar and which overhang said brackets, bolts having non-circular portions itting in non-circular holes formed in the eccentrics, and means for holding the bolts from turning after adjustment, substantially as set forth.

2. In an adjustable switch-rod, the combination of abar, brackets secured to the switchpoints and resting upon the switch-bar, eccentrics iitting in holes formed in the brackets and which are provided With non circular openings, straps secured to the switch-bar and which overhang said brackets, and bolts having non-circular portions fitting in the non. circular eccentrically-located holes in said eccentrics; said straps being provided with noncircular enlargements of the bolt-openings to receive the non-circular heads of said bolts, substantially as set forth.
