Application filed December 23. 1905. Serial No. 293,150.

To all whom it may concern:

Be it known that we, HENRY ELLIOT, Jr.,

and'WILLIAM H. ELLIOT, citizens of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new anduseful Im rovernents in Adjustable Switch-Rods, of W v'ch the following is a full,

, the purpose of drawing the switch-points connected 'by the rod toward each other or spacing them farther apart, so that they may belbrought at all times firmly to the trackral s.

Figure I is a top or lan View of our adjustable switch-rod. ig. II is a vcross-section taken through a pair of switch-points with our `switch-rod connecting them Aand through adjacent track-rails. Fig. III is an enlarged end elevation of one of the brackets in which the switch-rod is held, said switchvrod being shown in cross-section. Fig.. IV is in part a longitudinal section taken on line IV IV, Fig. V, through a fragment lof the switch-rod and through a portion of the bracket in which it is held and in part a side elevation of the bracket and a rportion of the switch-rod. Fig. V is a top or plan view of one of the brackets and a portion l,of the switch-rod therein. Fig. VI is a fragmentary top view of the switch-rod.

A designates the track-rails of a railwaytrack, and B the switch-points, which are adapted to be moved-to and from said trackrails.

1 designatesa switch-rod that o crates, as usual, beneath the track-rails; `T `s'switch rod is provided with circular holes 2.

3 designates brackets that are secured tol the switch-points B by any suitable means, such as bolts 3. Each of these brackets is provided with a U-shaped `extension 4, in-

upper arm is also provided'with a bolt-hole 6,

that is located centrally with respect to the non-circular socket 5. The lower arm of the extension contains a circular bolt-hole?.

8 designates eccentric disks that areseated in the Vcircular openings 2 in the switch-rod, these disks being designated eccentrics due to their being provided with bolt-holes that are offset from their centers. These bolt-holes in the eccentric disks are of noncircular form, as illustrated in dotted lines, Fig. V. j The eXtension-armsjof the brackets and the eccentric disks are adapted to receive bolts that consist of non-circular heads 9, which correspond in contour to the sockets 5` in the upper bracket-extension arms, non-circular shanks l0, that correspond in contour to the non-circular bolt-holes in the eccentric disks, and roundl threaded Shanks 11 that pass through the bolt-holes 7 in the lower bracket-extension arms and receive nuts 12. When the switch-rod is to be adjusted to carry the switch-points A, to which said rod 'is connected by the brackets 3, the nuts 12 are loosened on the threaded shanks of the bolts passing through the brackets and switch-rod. The bolts are thereby freedl sufficiently to permit of the heads 9 being lifted from the non-circular sockets 5 in the upper arms of the brackets. The bolts arethen rotated in either direction, and asl their non-circularl Shanks 10 remain in the non-circular bolt-holes in the eccentrics S said eccentrics are rotated in the holes in the switch --rods, with a result of shifting the HENRYELLIOT, JR., AND WILLIAM H. ELLIOT, oF sr. Louis, MISSOURI,

brackets 3 inwardly or outwardly, according l.

to the direction of rotation of said eccentrics, and the switchoints are drawn closer together or sprea more widely apart, according to requirements.

t will be seen that the threaded portion of the bolts being circular, such portionswill turn readily in the circular bolt-holes of the lower arms of the bracket extensions in securing the desired adjustment.

While we have shown and described our adj ustmentmeans in connection with both of the" brackets 'united to the switch-points and we vprefer to so utilize the parts, as a greater degree of adjustment may be obtained, we do not limit ourselves to the use of the adjustment means in connection with both of IOO the sWitch-pointcarried brackets, as our .improvement may be applied and used in connection With only one of the brackets.

We claim as our invention- 1.4 A switch-rod mechanism comprising a switch-bar having a circular or round hole therein, a disk fitting in said hole, a bracket secured to one of the switch-rails and provided With a U-shaped extension that embraces said switch-bar, and a bolt passing through said bracket extension and through said disk; the hole in said disk through which the bolt passes being eccentrically located and the head of Said bolt being non-circular and fitting, when in normal position, ina noncircular socket in the extension of said bracket, substantially as set forth.

2. A switch-rod mechanism comprising a switch-bar having a circular or round hole therein, a disk iitting in said hole and having an eccentric noincircular hole, a bracket secured to one of the switch-rails and provided with an extension that bears against Said switch-bar, and a bolt passing through said bracket extension and through said disk 3 said bolt having a non-circular portion {itting in the non-circular hole in said disk and the head of said bolt being non-circular and iitting, When in normal position, in a non-circular socket in the extension of said bracket, substantially as set forth.
