UNITED f STATES PATENT OFFICE.
HARRY S. HASKINS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EDWIN HARRINGTON 8U SONNOF SAME PLACE.
HOISTING-MACHINE.
SPECIFICATION .forming part of Letters Patent No; 272,439, dated February 20, 18,83.
' Application led December 14, 1882. (No model.)
To all whom it may concern:
Be it known that I, HARRY S. HAsKINs, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Hoisting-Machines, ot' which the following is a specification.
My invention has reference to hoistingmachines adapted to be shifted from one position to another and arranged to run upon suitable rails; and it consists in providing the flanges of the wheels on the travelers with gear-teeth, and gearing therewith one or more pinions adapted to be revolved by an endless chain and chain-Wheel to cause said traveler to move upon its rails and convey the hoisting apparatus with or without its load from one place to another, and in details of construction, as more fully set out in the following specification and shown in the accompanying drawings, which form part thereof. t
Heretotore in hoists of this class the travelers have been caused to travel b v simply pull-v ing or pushing upon the hoist or its load, and a great deal of power and labor was expended uselessly in overcoming the inertia, and when a heavy load was upon the hoist it was necessary to have two or more men to move it.
The object ofmyinvention is to provide suit- I able and cheap means, whereby one man with ease may cause the traveler to move along the rail and convey itsload wherever de'sired.`
In the drawings, Figure lis a side elevation of a traveler for hoists embodying myimprovements. Fig. 2 is a plan view of same. Fig. 3 is a crosssection of saine on line a; fr, and Fig. 4 is a cross-section ot'- a modified form of traveler.
A is the traveler-frame, and B are its grooved supporting rollers or wheels, and run upon the overhead track D. The frame B is kept in position on the rails by lug E, and is provided on the bottom with a hole or ring, F, through which the hook of the hoist ispassed. If desired, the hoist may be made integral with the traveler, though I prefer to make them separate. One or more anges, C, of the supporting-wheels are made with teeth, and are geared with the pinion I upon the shaft H, supportedV in a bearing, G, secured to the frame A. A chain-wheel, J is secured upon the outer end of shaft H, and an endless chain, K, passes over it, and is used to rotate the pinion I to -canse the traveler to move upon its track in eitherdirection.
When the track is an I-bealn two or four rollers vor supporting-wheels may be used in the manner shown in Fig. 4.
In place of making the iianges of the wheels toothed, I may provide suitable gear-wheels.
I do not limit myself to the construction of the devices shown. as they may be modified in various Ways without departing from my invention.
Having now described my inveu tion, what I claim as new, and desire to secure by Letters Patent, is-
l. In a hoistingmachine, a traveler having a support at the bottom and below the center of gravity of the said traveler for the hoisting lapparatus, supported upon wheels and adapted to run upon a track, provided with gearing arranged to cause said supporting-wheels having an independent axle to rotate, and a chainwheel and chain to pnt said gearing in action, substantially as and for the purpose specitied. 2. Ina hoisting-machine,a-travelersupported upon flanged wheels, one or more of said danges being provided with teeth, in combination with gearing carried by said traveler and adapted to mesh withsaid toothed tlanges, and a chain and chain-wheel to rota-te said pinion, substantially as and for the purpose specified. f
3. In a hoistingmachine, a traveler supported upon two or more toothed' flanged wheels and adapted to run upon a track, in combination with a piniongearing into two or more ot' said toothed Bauges, and a chain-wheel and chain to rotate said pinion, substantially as and for the purpose specified.
In testimony of which invention I hereunto set my hand.
HARRY s. Haskins.
