TTTED TATES PATENT BELA KORMENDY, 0F (I)LEVELAND, OHIO, ASSIGNOR T0 TI-IE THEODOR KUNDTZ COMPANY, OF CLEVELAND, OHIO, A CURPOBATION OF OHIO.
Application filed July 29, 1915.
To all whom it may concern:
Be it known that I, BELA KonMnNDY, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented cer tain new and useful Improvements in Adjustable Tables; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it per tains to make and use the same.
This invention relates to improvements in adjustable tables, and pertains more especially to a table comprising means whereby the top of the table may be placed in a slanting position or in a horizontal position.
()ne object of this invention is to provide means whereby the tabletop cannot only be placed in a slanting position, but in a horizontal position at different elevations.
Another object is to have said table-top shiftable rearwardly and forwardly in said positions;
Another object is to render the table simple and durable in construction.
With these objects in view, and to the end of attaining any other advantage hereinafter appearing, this invention consists in certain features of construction, and combinations and relative arrangement of parts, hereinafter described, pointed out in the claim, and illustrated in the accompanying drawings.
In said drawings, Figure 1 is a front elevation of the upper portion of a table embodying my invention and shows the top of the table in a slanting position. Fig. 2 is a vertical section on line 22, Fig. 1. Figs. 3 and 4: are vertical sections showing the table-top in horizontal positions. Fig. 5 is a horizontal section on line 55, Fig. 4:. Fig. 6 is a vertical section on line 6-6, Fig. 4.
The stationary portion or supporting structure of my improved table comprises two laterally spaced horizontally arranged parallel bars A which are arranged at the upper end of said structure and constitute supporting members for the top B of the table as will hereinafter appear. The bars A are connected together by a cross-bar C. The bars A extend forwardly and rearwardly and are arranged at the under side of opposite end-portions respectively and transversely of the top B.
Specification of Letters Patent.
Patented =1? none 27, 1916. Serial No. 42,492.
The top B is provided at its under side, at the outer side of each stationary bar A, with a bar 6 which extends longitudinally of said stationary bar. The top B is therefore provided at its under side with two forwardly and rearwardly extending bars 6 which are arranged at the under side of opposlte end-portions respectively and transversely of the top.
Each bar A of the stationary portion of the table is shown provided at its outer side with two parallel laterally and outwardly projecting pins 10 which are arranged horizontally and spaced longitudinally of said bar and consequently spaced longitudinally of the adjacent bar 5 of the top B. Said pins are therefore spaced forwardly and rearwardly. The top B is supported from the pins 10 and consequently from the stationary portion of the table.
Each bar 6 of the top B is provided at its inner side with two forwardly and rearwardly spaced pairs of vertically spaced parallel grooves or guideways l2 and 13 which extend longitudinally of the bar and consequently forwardly and rearwardly. The upper guideways 12 of said pairs of guideways are arranged in line and spaced endwise. The lower guideways 13 of said pairs of guideways are arranged in line and spaced endwise.
Each bar 6 of the top B is provided at its inner side and between the guideways'12 and 13 of each of its pairs of parallel guideways with an intermediate groove or guide way 14 which extends transversely of said bar, and preferably said intermediate guideway let is in communication at its upper end with the upper of said parallel guideways at the rear end of said upper guideway and in communication at'its lower end with the lower of said parallel guideways centrally between the ends of said lower guideway.
. The two intermediate guideways 14 of each bar 6 are parallel and spaced to correspond with the spacing ofthe pins 10, and
all the guideways 12, 13 and 14 are wide enough to receive the pins 10 and to permit the bars 6 of the table-top B to move on said pins to place said top in the desired adjustment. It will be observed therefore that the guideways 12, 13 and 14 are arranged to cooperate with the pins 10 in rendering the table-top l3 adjustable, and that said pins and said guideways have such relative arrangement that said top can be placed in a horizontal position at different elevations or in a slanting position and is shiftable rearwardly and forwardly in any position.
In Figs. 1 and 2 the relative arrangement of each pin-carrying top-supporting bar A and the top B is such that, as shown in Fig. 2, the forward pin 10 of said bar engages the upper guideway 12 of the for-. ward pair of parallel guideways in the adjacent bar 6 of said top at the forward end of said upper guideway and the rearward pin 10 of the last-mentioned bar engages the lower guideway of the rearward pair of parallel guideways in said last-mentioned bar at the forward end of said lower guideway and consequently the top. is in a slant. ing position.
In Fig. 3 the relative arrangement of the pin-carrying top-supporting bars A and the the top B is such that the pins 10 engage the lower guideways 13 at the forward ends of said guideways and consequently the top is in its upper horizontal position.
In Fig. a the relative arrangement of the pincarrying top -supporting bars A and the top B is such that the pins 10- engage the upper guideways 12 at the forward ends of said guideways and consequently the top is in its lower horizontal position.
The end walls of the guideways 12 and 13 are preferably formed by suitably applied blocks 15 of rubber or other resilient and compressible material, and the guideways of each pair of parallel guideways preferably correspond in length and have such relative arrangement that said guideways are in line vertically at their forward extremities in a horizontal position of the top.
I would also remark that each pin 10 of each bar A is preferably screwed intothe downwardly projecting wing 17 of an angle-plate with which said bar is provided, which wing is set into the adjacent side of said bar, and the other winglS of said plate is set into the top of said bar. That is, each bar A is recessed, as at 20, to receive the angle-plates provided with the pins 10 of said bar, and said plates are secured in place in any approved manner. I would also remark that theforward end-portions of the pinecarrying bars A are contoured as required to permit the placing of the table top in the slanting position shown in Figs. 1 and'2.
Not unimportant in my improved construction of adjustable table hereinbefore described is the extension of the lower guideways 13 rearwardlyof the lower ends of the connected intermediate guideways 14:
substantially as far as said lower guideways extend forwardly of said ends of said intermediate guideways so that the table-top B has an adequate range of adjustment for wardly and rear-wardly its upper posi-. tion shown in Fig. 3. Y
hat I claim is: p H
In a table, an adjustable top, and two parallel laterally spaced forwardly and rearwardly extending topsupporting bars, the top being provided at one'side of each top-supporting bar with a bar which extends longitudinally of said top-supporting bar, each top-supporting bar and the adjacent bar of the top being provided, at their op.- posing sides, the one with two laterallyprojecting pins spaced longitudinally of said bars and the other with two forwardly and rearwardly spaced pairs of vertically spaced forwardly and rearwardly extending paral- V lel guideways, the guideways of each pair of parallel guideways being arranged in line and spaced endwise, each guideway-carrying bar being provided between the guideways of each pair of its pairs of parallel guideways with an intermediate guideway establishing communication between said parallel guideways at a point spaced rearwardly from the forward ends of said parallel guideways, the intermediate guideways 'of said guideway carrying bar being parallel and spaced to correspond with the spacing of the aforesaid pins of the adjacent pincarrying bar, said pins being adapted to project into the guideways and the'g-uide ways being wide enough to receive said pins and to permit adjustment of the tabletop and each lower guideway extending rearwardly of the lower end offthe connect ed intermediate gnideway.
In testimony whereof, I sign the foregoing specification, inthe presence of two witnesses.
