SPECFICATION forming pari: of Letters Patent No. 392,497, dated November 6, 1888.

(No model.)

.To @ZZ whom it may concern:

Be it known that l, FRANK. D. Cantar/ron, a citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented a new and useful Hitehing-Post, of' which the followingis a specification.

My invention relates to improvements in bitching-posts for use in hitehing horses or other animals.

Figure 1 is a sectional view showing a part of the mechanism in operative position; and Fig. 2 is an enlarged sectional View, partlyin perspective, of the cap, which rests upon the sidewalk and through which the post passes. Fig. 3 is a sectional view of the cap, showing the inclines for forcing in the spring.

The same letters indicate identical parts in all the gures.

A indicates a section of common gaspipe, at the lower end of which is aplug, B, screwed or otherwise fastened into the same and tapered at its lower end, as shown in Fig. l. This plug serves the double purpose of excluding water from the lower end of the pipe A and forms a point to enable the said pipe to be driven into the ground. On the top of the pipe A a cap, C, is screwed or otherwise fastened, the functions of which will be hereinafter described. This cap is designed to rest upon the sidewalk or eurbstone, and is secured to the same by screws c, or in any other suitable manner.

Vithin the pipe-section A. is telescoped another section of pipe, l), which when not in use is lowered into the pipe A. The pipe D is provided at its top with a cap, d, to which is attached in any suitable manner a bitchingring, il. This cap l is provided on its lower side with an annular recess, d, which fits over a corresponding` annular bead or projection, c', on the cap (i, for the purpose of excluding water from the top ol' the pipe-section A.. lhe pi pel) is also provided with a spring, E, curved as shown in Fig. 1l.. This spring is held in place partly by its own resilience, but is held in operative position bythe bent top c, which projects loosely through a hole, c', in the pipe D. Thus it will be seen that when the pipe D is drawn up into operative position the spring lil slips over the top edge of the pipe A and prevents the pipe D from falling to the bottomy of' the pipe A, while the cap C prevents it from being drawn entirely out ofthe same.

The cap C is constructed as follows: The inside portion of the cap is ofthe same diameter as'the outside diameter of the pipe A, with the exception of' the inwardly-projecting flange F, the opening of which is of the saine diameter as the inside diameter of the pipe A. This flange serves as a stop, against which the spring E abuis when the pipe D is drawn up into operative position.

Vithiu the cap C, and cast integral with the same, is a stop, G, which projects inwardly a distance equal to the thickness of the pipe A. On each side of the stop G is an incline, g g, and a lug, g g', as shown in Figs. 2 and 3, for purposes to be hereinafter described. lVhen the cap is in place on the pipe A, the annular space between the top of the pipe A and the flange F is equal to twice the diameter of the projecting end of the spring E, for purposes which will be apparent from a description of the operation ofthe device which follows. Vhen the post is not in use, the pipe D is teleseoped into the pipe A, with the cap d resting upon the cap G, as before described. Vhen it is desired to use the post, the pipe D is drawn up until the spring E projects into the annular recess formed by the top of the pipe A and the flange F of the cap C. Vhen it is desired to lower the pipe D, it is drawn up until the spring touches the flange F. It is then turned around either to the right or left until the projecting end of' the spring abuts against the stop (l, when it is pushed down the incline g, causing the spring to .recede Vfar enough to again enter the inside of the pipe A, when the pipe D will drop to the bottom of' the pipe A by its own gravity.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-n 1. In a bitching-post of the character described, the cap C, provided with the flange F, the stop G, audbhenclines g, substantially In Witness whereof have hereunto suo as land for the purpose set forth. scribed my name in the presence of bwo sub- 2. A bitching-post Comprising the pipes A scribing Witnesses and D, the plug B, the spring E, the cap C, FRANK. D ARLETON. 5 provided with the ange F, the stop G, the W'itnesses:

nclines g und the lugs g', and the cap d, as CHARLES F. POTTER, and for the purpose seb forth. J. D. GARLETON.
