Specication of Letters Patent. l Patented May 24, 1921 Application led February 1, 1921. Serial No. 441,639.
county of New York and State of New York, have invented vcertain new and useful Improvements in Turntables for Vehicles, of which the following is a specification.
This invention relates to turntables, being intended more particularly for use in small` private garages to obviate the necessity of backing out the automobile housed therein, enabling it to be readily turned around to face the door of the garage.
The invention has for an object to provide a device of this kind suitable for use in connection with an automobile, and further to provide a simple arrangement of parts whereby the turntable maybe readily swung around by direct manual .application of force thereto, or may be operated through the intermediary of reducing gearing.
For further comprehension of theinvention, and of 'the objects 1 and advantages thereof, reference will be had to the following description and accompanying drawings,
and to the appended claims in which the various novel features of4 the invention are more particularly set forth.
Fi ure 1 of the drawings is a vertical sectiona view of a turntable constructed according tothe invention, indicating an automobile in position thereon, this view being taken on the line 1--1 of Fig. 4.
Fig. 2 is a plan view of the turntable as arranged for direct manual operation.
Fig. 3 is a vertical section being taken on the line 3 3 of Fig. 4.
I Fig. 4 is a plan view of the turntable',.this
View, as well as Figs. 1 and 3, showing the turntable equipped with the reducing gear- Fig. 5 is a transverse vertical section of a modified construction of the turntable, this view being taken on the line 5-5 of Fig. 6.
Fig. 6 is a plan view of this modification.
In constructing my improved turntable I provide-a base member 10 which rests upon a concrete flooring on foundation 11, which latter may be the floor of the garage. This base 10 may jhave a shallow up-standing iange v12 around three sides thereof, the side facing the door of the garage being un- Han ed.
i is turntable proper comprises a pair of .plankllike rails 14 secured together by and `Supported upon a series of transverse beams BARWICKI, citi-V 'secured to the rails by suitable fastening means such as the screws 16. n TheY rail on the left hand side ofthe turntable, consider- 111g the latter as seen looking inwardly from the doorof the garage, may'have a ange 14 extendin al'on the outer side thereof.
Fixed to t e un erside of the' center beam 15 is a downwardly projecting solid hub 17 which engages the base 10 tol provide the pivot on which the turntable rotates. l
Mounted on the underside of the turntable and spaced evenly around the center thereof on axes lyin in lines radial to the turntable, are a series of casters, v20 which form the support for the turntable. Fixed to one of the rails 14, and prjecting at. a general upward and outward inclination therefrom, is a oke 21 having a handle 22 at its u per endl4 By this means the turntable may e easily rotated by direct manual action when unloaded, or when a li ht car is mounted thereon. I
ounted to have vertical sliding movement on theturntable is a pinr23 which is here shown as guided in an eye24 upon the side of the rail 14, this pin being adapted to engage in either of a the base to hold the turntable in its proper position with theV rails pointing toward the door of the garage. j
The device as so far described is suitable for use with light cars, but for kuse with heavy cars I provide a reducing gearing for rotating the turntable. To this end the hub 17 hasA formed integrally therewith an extension 25 which projects into a recess 26 in the floor ll'under the base 10, this 'extension having formed thereon a worm lgear 274 pair of. sockets 25 inmeshes with` an idler gear 33 located above it, this gear 33 in turn meshing with an upper gear 34 fixed on a shaft 35 on which is a crank handle 36, these gears 33 and 34 being carried by a pair of bearings on the support be moved out of engagement with the gear when desired, I provide a lever 40, in the 1 recess 26, which is fulcrumed between its ends as `at 41 to the bottom thereof and connected at one end by a short link 42 with the support 31, the opposite end having a handle 43 thereon which extends upwardly through a suitable opening in the base 10.
By moving the lever 40 the support 31 may be swung on its hinge point, thus moving the pinion element 28 into or out of engagement with the gear- 27. A pin 45( slidably carried by the base 10, is adapte to engage in a suitable socket in the support 31 to hold the latter in position with vthe worm gear and pinion in engagement.
While, in the drawings I have shown the shaft 29 and support 31 as extending at right angles to theturntable, these parts may also be arranged at any other angle that may be desired.
In Figs. 5 and 6 of the drawings I have shown another arrangement of operating means for the turntable. In this arrangement a worin gear 50 is fixed to the base l0, as by the screws 51, this worm having a projecting hub 52 which engages in a socket element 53 `fixed to the underside of the central beam 15 to form the pivot for the turntable. i
Suitably journaled to and under the rails 14 is a transverse shaft 54 on which is a pinion 55 meshing with the gear 50. One
element 59 carried by the adjacent side rail. Upon the upper end of this shaft 58 is fixed another bevel gear 60 meshing with a like gear 61 on\a horizontal stub shaft 62 carried by the bracket element 59, this stub shaft 62 being adapted for rotation by a hand crank 63. lVith this arrangement no recess under the base 10 is needed, while the operator follows the turntable as the latter moves.
Having thus described my invention what I claim as new and desire to protectby Letters Patent of the United States is as follows 1. A device ofthe class described comprising a base, a turntable pivoted on said base, a worm gear-,fixed to said turntable concentric to its pivot, a worm pinion meshing with said worm gear, means for rotating said worm pinion, manually operable means for moving said worm pinion bodily into and out of engagement with said worm gear anda handle fixed to said turntable for manual rotation thereof when said worm pinion is disengaged from said worm gear.
2. A device of the class described comprising a base, a turntable pivoted on saidbase, a worin gear fixed .to said turntable concentric to its pivot, a worm pinion meshing with said worm gear, means for rotating said worm pinion, and means for movin said worm pinion bodily into and out o engagement with said worm gear, said means including a support on which said worm pinionV is mounted, said support being hinged to said base.
3. A device of the class described comprising a base, a turntable pivoted on said base, a worm gear fixed to said turntable concentric to its pivot, a worm pinion meshing withsaid gear, a shaft on which said worm pinion is fixed, an elongated support on which said shaft is mounted, said support being hinged adjacent one end to the said base, means for rotating said shaft, and a lever fulcrumed'on said base and engaging said support to swing the latter to move the said pinion into or out of engagement with the said gear.
4. A device of the class described comprising a base, ay turntable pivoted on said base, a worm gear fixed to lsaid turntable concentric to its pivot, a worm pinion meshing with said gear, a shaft on which said worm inion is fixed, an elongated support on which said shaft is mounted, said support being hinged adjacent one end to the said base, means for rotating said shaft, and a lever fulcrumed on said base and engaging said support to swing the latter to move the said pinion into or out of engagement with the said gear, a Socket in said base, and a pin vertically slidably carried by said' turntable and adapted to engage in said socket.
5. A device of the class described comprising a base, a worm gear fixed to said base, a turntable pivoted on said base concentric to said worm gear, a horizontal `shaft journaled on said turntable, a worm pinion on said shaft meshing with Said gear, and means for rotating said shaft, said means comprising a vertical shaft carried by the turntable, meshing bevel gears on the lower end of said vertical shaft and one end of said horizontal shaft, a Stub shaft adapted for'rotation by a crank, and meshing bevel gears on said stub shaft and the upper end of said vertical shaft.
In testimony whereof I have aiiixed my signature.
