ADJUSTABLE TABLE.
Specification of Letters Patent.
Applicatibn filed February 23, 1912. Serialflo. 878,521.
To all whom it may concern:
Be it known that I, Gnoncn W. ANGELL, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Adjustable Table, of which the following is a specification.
Mv invention relates to improvements in adjustable tables and more particularly to such tables that are vertically adjustable and its object is to provide improved means for raising and lowering 'the top of the table and holdingthe same in adjusted position and it consists essentially of the combination and arrangement hereinafter more fully de scribed and particularly pointed out in the claim, reference being had to the accompanying drawings, in which Figure l'is a side elevation of a device embodying my invention the table top being omitted as forming no part of my invention; Fig. 2 is an enlarged detail of a portion of the device shown in Fig. 1 with the top support somewhat elevated; Fig. 3 is a horizontal sectional detail taken through the axis of one 'of the elevating gears; Fig. 4 is a front elevation of the device in the position shown in Fig. 1; Fig. 5 is a detail in elevation showing the gearing at one side of the table; and Fig. 6 is an enlarged vertical section through the axis of one of the'gears shown in Fig. 5.
Like numbers refer to like parts in all of the figures.
The main frame of the table is preferably made of steel tubing and comprises four legs at the respective corners of the frame open at the top and connected by horizontal tie members 2 secured to the same thus forming a substantially rectangular frame preferably mounted on casters 3. The lower ends of the legs are preferably curved outward to increase the width of the base of the device. In each leg is a vertically slidable post 4 formed of tubing flattened on one side to recured to each other by suitable fastenings 15 surrounded by tubular sleeves 16 to space apart the housings in parallel planes each part of the housing'having inwardly turned edges whereby the contents of the housing are inclosed therein, and concave ends clamping the legs. To further secure the housings and legs to each other lugs'l'l' are secured to the legs, extend within the housings and the end fastenings 15 extend through the same. The housings thus form a part of the main frame and also furnish Patented Mar. 31, 1914.
bearings for the journals of the gears and shaft.
Across the frame from side to side and j ournaled in these housings is a shaft 11 provided with a crank 7 for manually rotating the same. On this shaft and within each housing is fixed a pinion 8 which oppositely engages gears 9 one of which gears projects through an opening in the side of a leg and engages the rack 6 therein. The other gear transmits motion to a similar gear which engages the rack in the leg at the opposite end of the housing each gear being mounted on a shaft 13 j ournaled in the housing, each housing thus contains a train of gears operated by a pinion on the shaft and the end gears of the train adapted to move the racks simultaneously and in the same direction as occasion may require by manually operating the crank 7. The two trains of gears 0 rated thus by a single shaft simultaneous y raise and lower all four of the posts equally.
To hold the device in adjusted position a pawl 12 is provided in each housing to engage one of the gears 9 and hold the same from rotatin From the foregoing description the operation of my device is obvious without further explanation.
What I claim is An adjustable table comprising a frame having four tubular legs spaced apart in pairs with each leg provided with an opening below its upper end, a post movable vertically in each leg, a rack on each post,connecting members between the posts, a housing bracing each air of legs and covering the openings in t e legs, a train of gears journaled in each housing with the end gears of each train projecting through. the corresponding openings in thelegs and meshing with the racks and corresponding posts, a rotatable shaft journaled in the opposite housings and provided with spaced pinions train toprevent accidental operation of the for mesh with the corresponding trams 0; gear trains,
ears each operated simultaneously and sai frosts raised or lowered according to the di- GEORGE ANGELL' 5 rection of'rotation of said shaft, and a dog Witnesses:
