VEHICLE-POLE TIP.

SPECIFICATION forming part of Letters Patent No. 439,640, dated November 4, 1890. Application filed $eptember 8, 1890. Serial No. 364,227. (No model.)

To all whom it may concern:

Be it known that I, CONRAD F. ELRICK, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Vehicle-Pole Tips; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

Figure 1 of the drawings represents a perspective view of my invention, showing the socket-cap inposition to be connected to the pole-tip; Fig. 2, a longitudinal section of the pole-tip and socket-cap in position ready for use; Fig. 3, an end view of the socket-cap, and Fig. 4, a crosssection on line m m of Fig. 2.

The present invention has relation to that class of vehicle-pole tips provided with means for retaining thereon a socket-cap, such means usually consisting of a stud and groove upon the cap and pole-tip, respectively.

The object of the invention is to improve the means heretofore employed, whereby a stronger and more durable device is provided, and which will present a much neater appearance, and also guard against dirt or grit working in between the joint formed by the poletip and cap, which objects I attain by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanyingdrawin gs, Arepresents the end of a vehicle-pole of the usual construction,to which is connected the metal tip B, the same having a socket O to receive the end of the pole, which is attached thereto by rivets or other well-known means. The outer end of the socket O is much larger in diameter than the tip B, so as to present an annular bearing-shoulder a, against which the end of the socket-cap D abuts when in place, as shown in Fig. 2, thereby forming a tight joint between the shoulder and edge of the cap and preventingsand and grit working in between the tip and cap, as well as presenting a neat appearance to the end of the vehicle-pole. The pole-tip B, at a point where it joins the shoulder a, has an annular supporting-flange b, which together with the shoulder form a perfect joint and also admit of the socketcap turning on the pole-tip. Immediately forward of the flange b is a circumferential groove 0, and joining this groove is the groove d, which latter extends the entire length of the tip B and has an open end for engagement therewith of a stud 6 upon the interior of the cap D. It should be noticed that these grooves are on a plane below the circumference of the tip B, so as to present a smooth surface for the interior of the cap D, and a more perfect fitting of the tip and cap is secured.

A further feature of the invention is the extension of the groove 01 at a point from the groove 0 to the extremity of the tip, so that the cap will not turn on the tip after being disengaged with the groove 0, and thereby prevented from turning until the cap is entirely removed.

when connecting the cap D to the tip B, the former is in position shown in Fig. 1,which will admit of the stud e being engaged with the groove d and the cap slid over the tip until the inner end thereof abuts against the shoulder a and the stud registers with the groove 0, after which the cap is turned to bring the stud out of register with the groove (1 and in engagement with the groove 0, and when the cap is turned to the position as shown in Fig. 2 the same will be firmly locked to the pole-tip. In removing the cap D it is turned so as to bring the stud e on line with groove cl, when it may be removed. The groove d, extending the entire length of the tip,prevents the cap turning while in the act of removing it.

The cap D is provided with a loop E or any other desirable and well-known means for attaching thereto the holdback straps or chains or the crossbar or other portions of a harness or attachments used with a vehicle-pole.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. The combination,with the socketcap D, having upon its interior a stud e, of the poletip B, having groove 0 and the longitudinal grooved, the same extending the en tire length of the tip, substantially as and for the purpose set forth.

2. The combination,with the socket-cap D, 5 having stud e, of the socket 0, having shoulder (1 and flange b, and the tip B, having groove 0 and the groove d, the latter extending the entire length of said tip, substantially as and for the purpose specified.

In testimony that I claim the above I have IO hereunto subscribed my name in the presence of two witnesses.

CONRAD F. ELRICK.
