HOlSTlNG MECHANISM FOR PORTABLE'ORTRACTION ENGINES.

SPECIFICATION forming part of Letters Patent No. 721,001, dated. February 17, 1903. Application filed July 3, 1902. Serial No- 114,29r. on model.)

To all whom it may concern:

Be it known that I, FRITZ BENDER, a citizen of the United States, residing at Littlerock, in the county of Saline and State of Missouri, have invented certain new and useful Improvements in Hoisting Mechanism for Portable or Traction Engines, of which'the following is a specification.

This invention provides simple, effective, and novel mechanism for elevating a portable or traction engine for any desired purpose, this mechanism being applied to the engine and adapted for use at a moments notice for raising or lowering the engine, as may be required, the hoisting mechanism being readily operable by means of the engine or adapted to be operated independent of said engine.

The primary object of the invention is to lessen the labor and obviate the loss of time usually resulting when loading the engine upon a truck or unloading it from said truck after reaching a destined place of, use.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eifecting the result reference is to be had to the following description and drawings hereto attached. 7

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a side elevation of a tractionengiue embodying the invention. Fig. 2 is an end view of the engine as seen from the front. Fig. 3 is a perspective View of the hoisting mechanism disassociated from the engine.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The engine illustrated may be of any type and has been selected simply to illustrate the application of the invention, which resides in the lif ting or hoisting mechanism comprising the elements hereinafter referred to in detail.

Lifting-bars 1 are located at the sides of the engine and are mounted in suitable guides 2 and are provided at their lower ends with shoes 3 to obtain a firm bearing upon the ground, plate, or block. Each lifting-bar is provided at one of its vertical edges with cogs or teeth 4, forming segments of a thread or spiral and in mesh with a worm-pinion 5, secured to the lower end of a vertical shaft 6. The upperend of each shaft 6 is provided with a pinion 7 in mesh with a worm 8, applied to a transverse shaft 9, journaled in bearings applied to the engine and provided at one end with a belt-pulley 10, adapted to be 0perated from the engine or to be moved by hand, as desired. The shafts 6 and 9 are conveniently disposed according to the design or type of engine provided with the invenr-ion, and by having both shafts 6 geared to the shaft 9 and to the lifting-bars 1 the latter are simultaneously operated, thereby lifting both sides of the machine alike, provided the ground is level or the shoes of the lifting-bars are properly. blocked.

In the event of it'being desired to operate the hoisting mechanism from the engine a drive-belt 11 connects the pulley 10 with the fly-wheel orrband-pnlley 12 of the shaft 13, connected for operation by means of the engine in any accustomed way. The pulley 10 being connected to the pulley 12 in the manner stated and the engine operated, the lifting-bars l are moved vertically downward to lift the engine and upward to lower the engine, as will be readily comprehended. The lifting-bars maybe located at any conyenient position; preferably near the front and at the sides of the fire-box, thereby enabling the shaft 9 to extend across the front of the engine, as indicated in Fig. 1.

Having thus described the invention, what is claimed as new is-- 1. In an engine of the portable or traction type, hoisting mechanism applied thereto and comprising lifting-bars mounted in vertical guides applied to opposite sides of the engine and having corresponding vertical edges provided with cog-teeth, vertical shafts, worm pinions applied to said shafts and in mesh with the cog-teeth of the lifting-bars, and a transverse shaft geared to each of the vertical shafts for simultaneous actuation thereof, substantially as set forth.

2. In combination with a portable tractionengine, vertical guides applied to the sides thereof, lifting-bars mounted in said guides and having vertical edges provided with cogteeth, vertical shafts, worm-pinions secured to the said shaft and in mesh with the cogteeth of the lifting-bars, a transverse shaft, s

and worm-gearing between the transverse shaft and each of the said vertical shafts, substantially as specified.

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