SPECIFICATION forming part of Letters Patent No. 650,329, dated May 22, 1900.

Application filed April 2 8, 1 8 9 9.

To @Zi wiwi/'t it may concern-.-

Be it known that I, JOHN KREMSER, a citi; zen of the United States of America, residing at Duquesne, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lowering Devices; and I do hereby declare the follow-V ing to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention has for its object the provision of certain new and useful improvements over my former patent on locomotiveelevators, No. 602,457, granted to me April 19, 1898.

The object of my present invention is to vfurther improve my elevator by adding to it a turn-table, a crane, a means of rotating the locomotive-wheels when setting the valves, and a means whereby the elevator is operated by belt-power.

Vith the above object in view the invention finally consists in the novel construction, combination, and arrangements of parts, as will be hereinafter more specifically described in detail.

In describing the invention in detail reference is had to the accompanying drawings, forminga part of this specification,and wherein like numerals of reference designate like parts throughout the several views,in which- Figure 1 is a side view of my improved elevator, Fig. 2 is a plan view of the same. Fig. 3 is an end View of the turn-table. Fig. 4 is a perspective view of the end of one of the elevator-beams Referring to the drawings, the numeral l designates upright or vertical columns, within each of which is arranged a vertical screw, such as 2. The bevel-wheels 3 are made fast to the upper ends of these screws at the tops of the columns. Bearings 4 are made fast tothe tops of the columns, and Within these bearings are loosely iitted the shafts 5, which have the bevel-pinions 6 secured to them, which mesh with the aforesaid bevel-wheels. A horizontal shaft 7 extends across from one column to the other and is loosely mounted in bearings 8 at the tops of the columns, andv this shaft is provided with the miter-wheels sain No. 714,915. (No model.)

9, which mesh with similar miter-wheels 10 upon the aforesaid shaft 5. A

The I-beams 11, upon which the rails 12 of the elevator rest, are each provided at their ends with a plate 13, which is made fast to the beams and extends over and around the vertical screws and rests upon large nuts 15, which are 'arranged upon the said screws. Between the aforesaid I-beams 11 is secured the spider 16, having the bearing-pin 14 projecting upwardly therefrom, and upon this pin is pivoted the turn-table 17, having the rail-pieces 18 secured thereon. Loosely arranged between these rail-pieces are the shafts 19 and 20, upon which are mounted the wheels 2l and 22. One end of the shaft 20 projects through the rail and is provided with the bevel-pinion 23, which is adapted to engage with the bevel-wheel 24 upon the horizontal shaft 7. A suitable lever 25 is arranged in connection with this shaft 7 for moving the aforesaid shaft one way or the other and causing the miter-wheels 9 and 10 to be disengaged when it is desired to engage the bevel-wheels 23 and 24. A belt-pulley 2G is provided upon the said shaft 7, whereby it may be coupled up to suitable power. The ends of the rails which lead from the switch or track are made fast to the tops of the columns by the brackets or chains 27.V

By applying power to the belt-pulley 26 the elevator is raised or lowered, as desired, and in replacing a pair of driving-wheels under a locomotive and in order to turn them to the desired position for coupling up with the drive-rods or the setting of the valves the wheels are run-onto the turn-table, as shown at Fig. 1 by the dotted lines, in such position that the small wheels 21 and 22 willV engage with the anges of the driving-wheels. Then by moving the lever 25 the miter-wheels 9 and 10 are disengaged and the bevel-wheel 24 is brought into mesh with the bevel-pinion 23.

Power is then applied to revolve the shaft 7, which in turn will cause the drive-wheels to revolve by the action of the wheels 21 and 22, until the drive-wheels reach the desired position. In removing the wheels the table is turned and the wheels run ont within reach of the crane and removed.

For-the purpose of raising and lowering the IOO truck and locomotive. wheels I have provideda crane, which consists in suitably attaching "a rope or chain 30 to the under side of the spider 16. This rope or chain is then passed down under a pulley 3l, arranged at the foundation, thence upward and over a bar 32, which is laid across the tops of the standards 33, and is provided at its end with a suitable hook 34. easily be raised or lowered by the elevator. I have also provided a drum 35 upon the shaft 7 for operating a suitable overhead crane. This drum is loosely fitted upon the shaft and provided With a clutch 36,'which by any suitable means may be caused to engage with the Y.

catch 37, which is fast upon the shaft, l,when it is desired to rotate the drum and operate the crane.

If it is desired to increase the height'of the elevator, I have shown an additional section 29 of an I-beam in connection with the I- beam ll at Fig. 4. This section is secured between each end of the beams and the platesy 1.3.

Having thus shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

'1. The combination with a series of hollow columns having a vertical screw arranged therein and provided with a nut,- of a plate mounted on the said screw and supported by the said nut, I-beams supported by the said plates, rails mounted upon the said beams, a turn-table suitably supported by the said libertins, bevel gear-wheels secured to the top of said screws,- a shaft provided with bevel= pinions connecting together a pair of the said screws, and means connected to the said shaft for operating the same thereby lowering the rails and said turn-table,- substantially as de; scribed 2. The combination with the elevator as described, of a turnstable, frictionwheels 2l and 22 arranged upon the said turn-table to engage withl and revolve the locomotivea Wheels, and a means whereby the said wheels are revolved, substantially as shown and described.

By this means the wheels may' 3. The combination with the elevator as described of a turn-table, friction-wheels 2l and 22 arranged upon the said table to engage with locomotive-wheels, the belt-pulley 26, arranged upon the shaft 7, and a means whereby power is transmitted from the said shaft 7 to the said friction-wheels, substantially as shown and described.

4., The combination with a series of hollow columns each having a vertical screw arranged therein and provided with a nut, of a plate mounted on each of said screws and supported by the nut, I-beams supported by said plates, rails'mounted on said beams, a turn-table mounted on the said beams and supporting the said rails, operating means for said table, bevel gear-wheels secured to the top of the said screws, and meaIlS connected to the said wheels and operative for lowering the I-beams, substantially as described.

5. The combination with the elevator and turn-table, of the rope or chain 30 secured to the said turn-table, a stationary pulley-block such as 3l arranged below the said table, the standards 33 and bar 32, all arranged and adapted as and for the purpose set forth.

6. The combination with an elevator, of a turn-table suitably supported thereby, means carried by the said table adapted to revolve the wheels of a locomotive or other vehicle, and means adapted to be connected to the said revolving means for operating the same, substantially as described.

7. The combination of an elevator, operating means therefor, a turn-table carried bythe said elevator, means for revolving locomotive or other wheels mounted thereon, operating means therefor, and suitable connections between the same and the operating meansof the elevator, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

' JOHN KREMSER.
