OPTI CAL SUPPORT TABLE Filed June 5, 1966 l NVEN'l "OR. Palm M JJZFEVZfW/b BY United States Patent 3,329,105 OPTICAL SUPPORT TABLE Paul M. McPherson, Acton, Mass., assignor to McPherson Instrument Corp., Acton, Mass., a corporation of Massachusetts Filed June 3, 1966, Ser. No. 555,057 3 Claims. (Cl. 108-144) This invention relates to the field of support tables, and more particularly to tables used for moving and stabilizing extremely sensitive optical apparatus.
Support tables now in use conventionally have four legs with wheels and four stabilizers by means of which the Wheels are raised equally off the ground for stable support. Lever means or hydraulic means are used to simultaneously actuate the stabilizers to elevate the table. These features, while adequate for many purposes, prove unsuitable for general use with sensitive optical apparatus which must be precisely levelled on fioors customarily a bit uneven, and which must be elevatable to diverse workin heights for use with other apparatus. Moreover, the means used often do not work smoothly, but permit apparatus to be bumped or jarred as it is raised or lowered.
Accordingly, the principal objects of the present invention are to provide a support table which olfers firm and stable support for optical apparatus, which is easily and precisely levelled without loss of stability during levelling, which is elevatable to diverse working heights, which can be lowered or raised smoothly and without jarring or bumping, and which, when mobile, safely and stably transports heavy and costly optical apparatus.
Briefly summarized, the invention is a mobile optical levelling table having a bench structure upon which the optical apparatus is to be placed, and a first set of legs attached to and depending from the bench structure. These legs have casters at their lower ends for mobility. In addition, a second set of three triangularly spaced hollow legs is attached to the bench structure such that the center of gravity of the table is located a substantial distance inside the triangle defined by the legs.'In each of these hollow legs there is an independently adjustable screw-jack means which is extensible downwardly from a position above the casters to a position below the casters, whereby the table may be smoothly raised and precisely levelled, or lowered carefully upon the casters. Each screw-jack means extends into a hollow leg a major part of the length of the hollow leg, so that the table has a wide range of possible elevations.
For the purpose of illustration a typical embodiment of the invention is shown in the accompanying drawing in which:
FIG. 1 is an isometric view showing the table supported for transport by the legs with casters, the screw-jack means being elevated above the casters;
FIG. 2 is an isometric view showing the table supported by-the screw-jack means, the screw-jack means being extended below the casters;
FIG. 3 is a plan view of the table; and
FIG. 4 is a section on line 4-4 of FIG. 3.
In the particular embodiment of the invention chosen for the purpose of illustration, the table has a bench structure 1 comprising a flat top portion 2, a fiat bottom portion 3, and a peripheral skirt 4 extending between the top and the bottom portions. As shown in FIGS. 1 or 2, portions of the top portion, the bottom portion and the peripheral skirt are removed to reduce the weight of the bench structure.
Attached to and depending from the bench structure 1 is a first set of three spaced legs, 1a, 2a, 3a. This first set of legs is spaced to form a triangle; the leg 1a being centrally located at one end of the bench structure 1, and the legs 2a and 3a being located at the corners of the opposite end of the bench structure.
As shown in FIG. 4, each leg 1a, 2a or 3a comprises a hollow tube 5 which fits through a circular hole provided in the bottom portion 3 of the bench structure and abuts the top portion 2. Tack welds secure the tube 5 to the top and bottom portions of the bench structure. In the lower end of the tube 5, and secured thereto by welding or the like, is a cylindrical block 6, to which a swivelling caster 7 is fastened.
-The first set of legs 1a, 2a and 3a stably supports the table when it is transporting optical apparatus. As shown in FIG. 3, the center of gravity of the table is substantially within the projection of a triangle defined by the first set of legs. To further increase stability during transport of apparatus, it is preferable that the first set of legs be susbtantially shorter than the intended operating height of the table. This provides a low center of gravity for the table and apparatus when it is mobile and permits safe negotiation of ramps and uneven surfaces without danger of tipping.
Also attached to the bench structure 1 and depending therefrom is a second set of three spaced legs 1b, 2b and 3b, terminating above the first set of legs. This second set of legs is triangularly spaced as shown in FIGS. 1, 2 or 3, the leg 1b being centrally located between the legs 2a and 3a at one end of the bench structure 1, and the legs 2b and 3b being located at the corners at the opposite end of the bench structure. As shown in FIG. 3, the center of gravity of the table also lies substantially within the triangle defined by this second set of legs, so that either set of legs supports the apparatus stably.
As shown in FIG. 4, each leg 1b, 2b or 3b comprises a hollow tube 9, fitting through a hole provided in the bottom portion of the bench structure, and abutting the top .portion 2 of the bench structure. Tack welds secure the tube 9 to the bench structure. A cylindrical plug 10 is inserted in the upper end of the tube 9 and secured thereto. A hole 11, threaded to receive a machine screw, is provided in the plug 10 and upper portion 2 of the bench structure.
A plurality of cylindrical guide blocks 12 is spaced lengthwise of the interior of the tube 9 and secured thereto by welding or the like.
In each of the hollow legs 1b, 2b and 3b, a screwjack 13 threada-bly engages the guide block 12 so as to be adjustable axially in the tube 9. Each screw-jack extends into a hollow leg a major part of the length of the hollow leg. This permits the table to be raised a substantial distance and provides a wide range of operating heights. At the lower end of the screw-jack 13 a ball-and-socket levelling pad 14 is provided to obtain firm support on uneven surfaces. Just above the levelling pad, gripping means 15 are provided, whereby the screwjack may be rotated and adjusted axially with a wrench or the like. Alternatively, a lever may be attached to the screw-jack to facilitate its rotation and adjustment.
As shown in FIGS. 1 and 4, the screw jacks 13 are extensible upwardly to an elevated position above the bottoms of the casters 7 on the first set of legs. When so elevated, the table is mobile. As shown in FIG. 2, the screw-jacks are also extensible downwardly to a lowered position substantially below the casters, thus raising the table to a desired working height. As described, each screw-jack means is independently and continuously adjustable, which permits the table to be easily and precisely levelled. The provision of exactly three screw-jack means, spaced triangularly about the center of gravity of the table, assures that the table will remain stable during the levelling process. And the continuous, even motion Q of the screw-jacks assures that sensitive apparatus will not be jarred or bumped as the table is raised or lowered.
It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
