Specification of Letters Patent.

Patented June 6;, 1916.

Application filed July 24, 1914. Serial No. 852,832.

To all whom it'may concern:

Be it known that I, STANLEY W. Harms, a citizen of the United States, Richmond, in the county of Wayne and State of Indiana, have invented the following described new and useful Improvements in Target-Stands.

The invention is and simple parts, so combined and arranged as to be economically produced and protected in operation against interference by or other foreign material, and also to be capable of operation with a minimum of frictional resistance.

In theaccompanying drawing, Figure 1 is a vertical elevation of such a target top plan thereof; Fig. 3 a side elevation, with the staff broken off; Fig. 4 a horizontal section just above the 5 a bottom plan of the base; Fig. 6 a vertical section in a'radial plane; and Fig. 7 a vertical section through'the lateral opening of the protecting chamber.

The base of the target stand'is a fanshaped casting 1, with spike-holes arrange along its longer or wider end 2, and the bearings for the target staff at its smaller or pointed end 3, the spike-holes being separated sufliciently from each other to provide a stable support upon the tie or'road-v bed. On its under side the base is reinforced by a series of ribs 4 (Fig. 5), which converge from the spike-holes toward the pointed end, and also by a marginal flange 5, the spike-holes being formed in the relatively thickened junctions betweenthe ribs and the flange. At its smaller or pointed end thecasting is provided with an upstan 6, of general semi-circular sectional shape, and a series of angle-ribs side of the casting serve to brace and strengthen this portion. angle-ribs also converge toward the smaller end of the casting or the axis of the target sta The wall portion 6 in the present instance is disposed entirely above the general plane of the base-plate but this is not essential. The wall portion 6 forms a chamber, the roof of which is dome-shaped, as indicated at 8, and provided with an aperture forming the upper bearing for the target stafi 9. The other staff bearing is formed in the floor of the chamber and consists of an an- 10, projecting somewhat above the chamber floor, and a step-piece 11,which residing in V .a target stand of few.

7 against displacement by hese pieces of projects upwardly from the bottom of the recess wlthin the boss, these parts being arranged so' as to provide ample clearance around the step-piece .11, as shownin Figs.

6 and 7. 'Both staff bearings are, of course, formed in alinement with each other and may be easily formed in the casting, to be then reamed out and finished by a single operation with a reamer. The crank, arm 12 is secured to the staff 9, between its bear.-

ings inthe roof and floor of the chamber,

and is preferably threaded crosswise through a hole in the stafi, so that its effective length can be varied, and its inner or fulcrum end will normally project more or less into the interior of the chamber, while its oppos1te or connection end will extend outside ofthe chamber and beyond the base casting where it is connected with the connecting rod in the usual manner. In the present case the crank-arm and after it has been adjusted, is held the hooked end of the connecting rod, which ispinned to its eye. Asleeve 13 surrounds the'target stafi between its bearings, and the crank arm 12 passes through the sleeve as well as the staff, sothat when theseparts arerassembled, the staff cannot be unstepped without first removing the eye-bolt. Manifestly the penetration of the eye-bolt in or through the staff serves as the primary locking agency, the sleeve '13 being merely a filler to occupy such space in the chamber opening as is not occupied by the staff and eye- I desirably continuous, with no openings therein, so that foreign objects, such as ballast, coal, or the like, cannot obstruct the free movement of the inwardly projecting or fulcrum end of thecrank 12, andjalso so that rain and snow are exclude The pointed shape of the base casting tends also to prevent obstruction is an eye-bolt,

fill and close to the operation of the stand, since thereby ample clearance is provided for the eye of the crank. The roof of the chamber is desirably domeshaped, so as to shed water, but is cast with an interior enlargement or counterbore 8 so that the whole thickness of the domeshaped portion will reamed to form the stafl' bearing, and the interior of the chamber is. provided with-four drainage holesll, located between the ribs 4, to drain away such water as may run down the staff through the upper bearing.

he annular clearance space in the stepbearing in the floor of the chamber is likea base having spike holes along one edge Wise provided with drainage holes 15, for the same purpose but the elevation of the boss 10 and the protection afforded thereto by the sleeve 18, ordinarily prevent the entrance of water to the interior of the step.

Above the base, the target staff carries the usual target 16, and the fitting 17, for a signal lamp.

I claim:

1. target stand comprising a base having an upstanding portion forming a closed, water-shedding chamber with a lateral opening therein, in combination with a target staff supported by the upper and lower portions of such chamber and substantially closing the lateral opening.

2. A target stand comprising a base plate having an upstandingintegral wall portion forming a chamber with in combination with a target stafi stepped in the floorof the chamber and journaled also in the roof thereof, and a crank arm on the said staff, the crank arm portion of said staff substantially closing the aforesaid lateral opening. 3. A target stand comprising a base havchamber adjacent to the edge of the base and said chamber having a lateral opening, incombination with a staff journaled in the roof and floor of the chamber and having a crank arm, the junction of arm and staff substantially closing the said lateral openmg. 7

4. A target stand comprising a base having an upstanding wall portion forming a chamber normally closed at the top and sides but having a lateral opening, a staff journaled in the roof and floor of the chamber, a crank arm on the stafi adjustable crosswise thereof, the junction portions of crank and shaft being arranged to close the said lateral opening with the inner end of the arm inclosed within the chamber.

chamber, and a crank thereon extended away from the chamber, the junction of the crank and staff serving as a closure to the lateral opening. 6. In a target stand, the combination of an uprig t stafl, a crank arm thereon adapted for adjustment crosswise of the staff, whereby its fulcrum end may extend in rear of the staff, a base plate providing bearings for such staff above and below the crank arm and also providing a protecting and inclosing chamber for the crum end of the crank arm.

7. In a target stand, the combination with providing a a staff ourthe chamber,

-a crank arm having one end projecting adjustably through the stafi and adapted to swing within the chamber, and its other end projecting beyond the chamber and base plate, and provided with connection means.

8. A target stand comprising a substantially fan-shaped base-plate with upright wall portions forming a chamber adjacent to the smaller end of the base-plate, a target staff stepped in the floor and journaled in the roof of the chamber, a sleeve surrounding the target stafi between its bearings, and a crankarm having one end extending beyond the sleeve and staff into the interior of the said chamber.

9. A target stand comprising a substan tially fan-shaped base having spike-holes along its longer side and an upstanding wall portion forming a protecting chamber at smaller end thereof, a water-shedding roof for said chamber, a target staff journaled in the roof and stepped in the floor of the chamber and an eye-bolt crank arm threaded to the shaft between its bearings, the eye being without the cham ber and its opposite end within the chamber.
