y renewable as is usually desirable from time to time in devices of this character.

The invention may be best lunderstood'by reference to the accompanying drawings, wherein: 'i v Figure 1 is' a sideview of ashoe and its mounting at the end of a trolley pole;

Figure 2 is a section taken on line 22of Figure 1; v .c l

Figure 3 is a section taken on line 3-5-3 of Fi re 1'; and n A igure 4 is an enlarged perspective View of the renewable shoe itself.V i

In the drawings, my invention is illustrated inV connection with a mounting including a base part' 10, pivotally supported between a pair of upright side plates 11, 11a, forming a yoke connected at the ends which are suitably mountedv cna support 12. In the form shown the pivotalconnection of the base 10 is provided by means of'a pair of inwardly extending spherical pro] ections 14, 14, on the inner faces of the side platesr 11,

11a, respectively, which fit in corresponding`A shaped sockets 15, 15, formed atvthe opposite sides of the baser 10 adjacent its upper edge. One of the side plates 11 is pivoted at' its lower edge to the support 12 by ay pin 16 so as to permit the side plate to be swung downwardly tol release the baselO'when desired. The two side plates are secured in engaging position on opposite sides of the base by suitable means such as a cross pin 17 w ich i Wlthout departmg from the Splrlt and Scope in the form shown extends through an arcuate recess 18 at the lower part of the base 10 mounted on the upper faceof the base 10;

As shown in the drawings, the upper face of said base 10 is iinished with a substantially 192e.y serial No. 382,030.

plane surface 21 and with its opposite end surfaces 22, 22, inclined inwardly and downwardly at an acute angle to said upper surface r21, as shown. The shoe 20 is provided with correspondingly shaped inwardly lfacing shoulders 23, 23, at the opposite ends, ar` ranged so that the vshoe kmay be fitted sidewise into sliding engagement over thek base 10 and retained thereon in-closely fitting engagement by the overhanging end portions of the latter.

In order to mount the shoe member 20 on the base 10 it is necessary that said base be dismounted from its pivotal connection With ythe side plates 11, 11a, or at least, the pivoted side plate 11 ymust ybe swung'out of engagement with the, adjacent side of the base. When the two y'side plates are moved vinto their normal positions, as shown in Figure 2, thev upper ends of the side plates 11, 11a,

engage opposite sides of the shoe 20 to lock it in proper position on the base.

lWith the construction above described,"

kthe shoe 20 is readily removable by merely taking out thev cotter pin 17a in pin 17, and then swinging the adjacent end plate 11a outwardly so as to permitthe old shoe 20 to be removed sidewise from the base 10 and replaced by another shoe of a similar-construction. Whereupon the side plate 11 is again secured by means of the bolt 17 Vand cotter Y pin 17a with the new shoe firmly secured on the base. f Y y u Y Although I have shown and described one form in which my invention may be embodied, it will -be understood that the ar-` rangement and construction ofthe various parts thereof maybe altered or changed said base and secured at opposite'sides Within said yoke.

2. In a trolley pole, a base, a separable yoke engaging opposite sidesv of said base and permitting pivotal movement therebetween, and a Adetachable shoe Vadapted to lit side- Ways on said base With said end portions interlocking opposite ends of said base and secured at opposite sides Within said yoke.
