SPECIFICATION forming part of Letters Patent No. 586,408, dated July 13, 1897.

Application filed March 17, 1897.

To all whom it may concern.-

Be it known that I, JOHN T. WTLLIAMS, a citizen of the United States, residing at Carbondale, in the county of Lackawanna and State of Pennsylvania, haveinvented certain new and useful Improvements in Domestic Trucks and Elevators, of which the following is a specification.

The object of my invention is to provide means for lifting land moving washboilers, tubs, and the like, so as to dispense with much of the heavy work now required in domestic laundry operations.

In the accompanying drawings, which illustrate my invention, Figure 1 is a perspective view illustrating the manner of using my device. Fig. 2 is a side view showing the elevating mechanism in section. Fig. 3 is a plan view of the device, and Fig. et is a section of the platform on the line 4 ci. of Fig. 3.

Referring tothe drawings, Figs. 2, 3, and 4, 1 indicates a wooden base provided with casters 2 and having mounted thereon a plate 0r pedestal 3, having a screw-threaded opening in the center into which the lower end of the tubular standard 4, provided with an external thread, is iitted. Within the upper end of the standard a is a tubular fitting 5, having ariiange 6, which extends over the en d of the standard and supports the fitting therein. The fitting 5 is internally threaded to receive a screw-threaded rod 7, to the upper end of which is rigidly secured a metal crosspiece 8, forming a support for the platform 9. The platform, as shown in the drawings, is designed to accommodate the ordinary elongated form of boiler shown in Fig. 1. The support S is therefore provided with two long arms 8a, extending lengthwise -of the platform, and two shorter cross-arms 8b, eX- tending from side to side, upon which the elongated platform 9 is secured. The platform consists of a U-shaped wooden frame 10, provided with a series of rollers 11, extending between and having bearings in the sides of the frame. This frame rests upon a metal strip or plate 12, similar in outline to the frame 10 and having upturned ends 13 covering the ends of the fram'e, and a crosspiece 14., extending between its opposite sides near its ends. This frame 10 and the plate 13 are secured to the ends of the arms of the Serial No. 628,024. (No model.)

support by any ordinary means, such as bolts or screws passing through the arms. The journals of the rollers 11 rest in recesses which form bearings in the frame 10, or they may be provided with any suitable form of bearing set into the frame. The surfaces of the rollers l1 extend slightly above the frame 10. A metal Iiange' 15 is secured to the outside of the frame 10 and extends around the sides and the curved end thereof, its upper edge projecting above the plane of the upper surfaces of the rollers. The platform is thus surrounded on the sides and one end by a flange, the opposite end being left unobstructed, so that the boiler or other vessel maybe slid onto the rollers. A set-screw 16, provided with a handle 17, extends through the standard 4 and fitting 5, and is adapted to secure the rod 7, when desired, and prevent it from turning.

The manner of using my improved device is as follows: lVhen it is desired to place a boiler upon the stove, the platform is lowered, through the medium of the screwrod 7, by revolvin g the platform in the proper direction. The boiler is then lifted onto the rollers,and by revolving the platform in the opposite direction it may be raised to the level of the stove. The device is then 'moved over to the stove and turned, so that the end which is not provided with a ange will be next the stove. The boiler may then be pushed off of the rollers without diiiiculty to its position on the stove. To remove the boiler from the stove, the operation is reversed.

The platform may befof any desired shape and the device may be used for raising, lowering, and moving variousheavy vessels and objects, particularly such vessels as are used for domestic laundry-work. By the use of the set-screw 16 the platform may be prevented from turning and it may be set at any desired height, so that the device may serve a useful purpose as an adjustable wash bench or table.

Having described my invention, what l claim, and desire to secure by Letters Patent,

1. In a domestic truck and elevator, the combination with a support mounted upona screw-shaft, of a frame secured to said support, parallel rollers mounted in said frame,


and a Iiange partially surrounding the frame and extending above the rollers, substantially as described.

2. In a domestic truck and elevator, the combination with a support mounted upon a screw-shaft, of a frame having parallel sides secured to said support, rollers extending between said sides, and a flange secured to the sides and passing around one end of the frame and extending above the rollers,substantially as described.

3. In a domestic' truck and elevator, the combination with a platform having a series of parallel rollers upon its upper surface,and a support for said platform mounted upon a screw-shaft, of a base mounted upon rollers, and a standard carried by said base and adapted to receive said screw-shaft, substantially as described.

4. In a domestic truck and elevator, the combination With a support mounted upon a screw-shaft and having radiating arms, of a plate l2 having upturned ends 13 anda crosspiece 14, upon said arms, a frame l0 upon said plate, rollers extending between the sides of said frame, and a Hange l5 secured to the sides of said framev and passing around one end thereof, substantially as described.

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