Specification of Letters Patent.
Patented May 5, 1914.
App1icationfi1ed 0ctober 6, I913.- 'Seria1No. 793,595.
To all whom it may concern of Minnesota, have invented certain new and useful Improvements in Self-Serving Dining-Tables, of which the following is a specification.
This invention relates to improvements in self-serving dining tables and its object is to produce a device of this kind in which the operating mechanism is hidden from view giving the table the appearance of the ordinary dining table.
The invention comprises a spring motor for rotating the central portion of the table top and means for automatically keeping said motor inoperative and manually operable release means whereby said motor is rendered operative.
The invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawings which form a part of said specification and in which Figure 1 is a view of my improved selfserving table in elevation. Fig. 2 is a vertical section through the table. Fig. 3 is a sect-ion taken on line 33 of Fig. 2. Fig. 4 is a plan view of a portion of the table top. Fig. 5 is a plan of the motor casing showing the locking means for normally retaining the motor inoperative. Fig. 6 is an enlarged detail taken on line 66 of Fig. 1. Fig. 7 is an enlarged view of a portion of Fig. 2.
Like reference characters indicate corresponding parts throughout the several views.
1 is the base of the table which may be provided with casters 2 and which carries the pedestal 3 that supports the circular frame 4 in which the support 5 is disposed that carries the motor casing 6 in which a suitable spring motor (not shown) is disposed.
7 is a pivot suitably supported in cross pieces 8 secured to the motor casing and upon said pivot the rotary disk 8 is carried that is secured as at 9 to the central portion 10 of the table top. The cross pieces 8 are apertured as at 11 in one extremity to permit access by angular ends of the arms 12 to the serrations 18 formed in the periphery of the circular rotary disk 14. carried upon pivot 7. Each of the said arms 12 is pivoted in a bracket 15 carried by one of the cross pieces '8' and the end of said arm 12 remote from Be it known that I, HARRY STRANDBERG, a. citizen of the United States, residing at Newfolden, in the county of Marshall and Statev the serrations 18 is beveled for engagement with :the beveled :periphery of a collar 16 carried loose upon the pivot 7. Each arm 12 is further connected by a spring 17 to a cross piece 8' and said spring is disposed upon said cross piece between the bracket 15 and the non-beveled end of said arm; the purpose of the spring 17 being to normally keep the angular end of the arm 12 in engagement with the serrated periphery of the disk 14. looking said disk and the beveled end of said arm in engagement with the collar 16.
Each bracket 15 carries a pulley 18 over which a cord 19 passes which cord also passes through apertures 20, 20 in the cross pieces 8 and over a depression 21 formed in said pieces and up through an aperture in the collar 16, the opposite end of said cord passing from the pulley out through an aperture in the frame 4 to and about a plunger 22 partly disposed in a pocket 23 secured to the stationary portion 26 of the table top and to said plunger the cord 19 is secured by a wedge 24.. The said plunger rests upon a spring 25 disposed in the pocket 23 and passing through the stationary portion 26 of the table top which is of annular formation and disposed about the movable portion 10 of said top. The said ring 26 is supported by the frame 4: of the table. In operation the springs 17 retain the arms 12 normally in engagement with the serrations 13 of the disk 14:, which disk is thus kept stationary and since said disk is secured to the pivot 7 connected to the motor the motor is retained normally in inoperative position. To release the motor and so revolve the movable portion 10 of the table one of plungers 22 is depressed thus drawing one cord 19 taut and causing the collar 16 to descend upon the pivot 7 depressing the beveled extremities of all of the arms 12 releasing the rotary disk 14 and permitting its rotation by the motor and likewise the rotation of the pivot 7 and of the table top 10.
What is claimed is-:
In a self-serving dining table provided with a base and a pedestal disposed thereupon, a frame, pockets associated with said frame, a stationary annular top carried by said frame, a motor casing provided with a motor suitably supported within said frame, a pivot projected into and supported upon said motor casing and operatively associated with said motor, a serrated rotary disk car whereby the latter member may be made to disengage said locking arms from the said serrated disk.
In testimony that I claim the foregoing as my own I have hereto aflixed my signature 15 in the presence of two subscribing witnesses.
