FREDERICK V. WINTERS, OF NEW YORK, N. Y.

SHOE FOR ELEVATOR-GUIDES.

To all 'whom it may concern:

Be it known that I, FREDERICK V. VVIN- TERS, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shoes for Elevator-Guides, of which the following is a specification.

My invention relates to shoes for elevator guides.

The objects of my invention are to provide an elevator shoe so mounted as to slide horizontally toward the guide and also to turn or swing longitudinally and laterally, and also to provide the shoe with removable wear plates for the three sides of the guide adapted to be sold separately and applied in lieu of a worn out set. These objects I accomplish by the mechanism shown in the accompanying drawing in which Figure 1 is a sectional plan of an elevator guide and a shoe having my improvements applied thereto; Fig. 2 is a central vertical section therethrough; Fig. 3 is a detail sectional view of the shoe removed from its casing or support; Fig. 4 is a perspective of the three wear plates separated; liig. 5 is a perspective of the top plate which retains the wear plates; Fig. 6 is a like view of the bottom plate; Fig. '4 shows another form of wear plate.

A, designates an elevator guide of any suitable material and B, designates the usual casing to be mounted on the elevator and in which is mounted the spring pressed sliding stem or shank C, of the shoe G. The rear side of the shoe C, is provided with a transversely apertured lug 0, through which and the apertures in a yoke C is passed the horizontal pivot bolt or pin 0 The yoke C is exteriorly threaded at 0 and the stem or shank C, is provided adjacent thereto with collar 0 engaged by the inturned flange 0 of an internally threaded coupling sleeve C The shoe C, therefore has a universal movement since it turns longitudinally on the bolt or pin 0 and has a horizontally turning movement at the coupling C If desired the abutting faces of the stem 0, and yoke C may have anti-friction balls a seated in half recesses therein. The shoe C is preferably made with its sides 0 0 as angle plates bolted to the back member 0 so that either side plate may be renewed in case of breakage without the necessity of an Specification of Letters Patent.

entire new shoe. The shoe C, is of greater width and depth than the guide A, and loosely straddles the same but is made to properly fit the guide by means of a wear plate formed of the renewable wear plate sections D, D, D The front edges of the shoe are provided with inwardly extending longitudinal flanges c which receive the rabbeted edges (Z, (Z, of the side wear plates D, D while the adjacent edges of the rear and side plates D, D, D are provided with rabbets or grooves cl, (Z, (Z (Z whereby a flush joint is effected and the wear plates will snugly fit the interior of the shoe C.

The upper and lower ends of the wear plates are provided with inclined recesses d", which receive inclined lugs c on the inner faces of the top and bottom retaining plates E, E. These lugs e and recesses (Z hold the wear plates D, D from any accidental displacement as the plates wear down in use. These plates E, E are secured to the shoe by screws e as shown.

In order that the lubricant may pass through the side plates D, D I provide them with apertures 6Z5, thus the lubricant passing between the shoe and these plates D, D will run through the holes to the guide A. The other wear plate D, has transverse lubricant retaining recesses cZ next to the front face of the guide A.

The top retaining plate E, is provided .with a recess 6 to collect any surplus lubricant from the guide and allow it to flow back thereto, through the apertures 0 to the interior of the shoe and its wear plates.

The wear plates D, D, D may be made of wood, fiber, composition or any material suitable for the purpose and they may be made in standard sizes and kept in stock so that when sets are worn out new ones may be readily substituted.

It will be seen that by having the shoe itself capable of universal movement it will not be necessary to have the wear plates themselves mounted for individual universal movement, and simplicity and cheapness of construction is thereby facilitated. At the same time the vibrations of the car in all directions are taken up by the universally jointed shoe. These wear plates are not individual pressure plates requiring a special construction of shoe having spring pockets, but my wear plates are readily adapted to the usual form of shoe and have no movement in the shoe. Furthermore the wear plate may be made in a single piece if so desired, as shown in Fig. 7.

I do not confine myself to any particular form of Wear plate so far as my universally jointed shoe is concerned.

WVhat I claim is:

1. An elevator shoe comprising, a casing or support, a spring pressed stem carried thereby, a shoe and universal connections between the stem and shoe.

2. An elevator shoe comprising, a casing or support, a spring pressed stem carried thereby, a shoe, a yoke, a horizontal pivot connecting the yoke and shoe, and a coupling sleeve rotatively connecting the adj acent ends of the yoke and stem.

3. The combination in an elevator guide, with a casing or support, and a shoe having a stem mounted in said support, and a universal joint connecting the shoe and stem, of a removable wear plate mounted in the shoe.

4. The combination, in an elevator guide, with a shoe having inwardly extending flanges along its side edges, and provided with removable top and bottom plates, of a removable wear plate for the three sides of the shoe, held in place by the said flanges and top and bottom plates.

5. The combination, in an elevator guide, with a shoe having inwardly extending flanges along its side edges, and provided with removable top and bottom plates, of a wear plate mounted in the shoe and comprising side plates and a back plate held in place by the said flanges and top and bottom plates.

6. The combination in an elevator guide, of a shoe having removable top and bottom plates of a removable wear plate held Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

in the shoe by said plates and interlocking connections between the top and bottom plates and the ends ofthe wear plate.

7. The combination in an elevator guide, of a shoe having removable top and bot- I tom plates, of a sectional wear plate held in the shoe by said top and bottom plates and interlocking connections between the top and bottom plates and the ends of the wear plate sections.

8. The combination in an elevator guide, of a shoe having removable top and bottom plates, of three interlocking wear plate sections held in the shoe by the top and bottom plates; the side wear plates having transverse apertures and the back wear plate having grooves or recesses in its working face.

9. The combination in an elevator guide, of a shoe having removable end plates, the top end plate having an oil chamber in its upper face leading into the shoe opening, of three wear plates held in the shoe by said end plates, the side wear plates having transverse apertures.

10. In an elevator guide, a shoe provided with a universally jointed spring pressed stem, removable top and bottom plates, and a wear plate held removably and fixedly in the shoe by the top and bottom plates.

11. In an elevator guide a wear plate formed in three sections having rabbeted meeting edges and top and bottom retainmg recesses.

In testimony whereof I afiix my signature in presence of two witnesses.
