Patented Feb. 18,v 1947 unirse srr s am orrllcez This invention relates to an adjustable support designed for supporting oce appliances, such as typewriters, adding machines or the like, the primary object of the invention being to provide a support of this character which may be adjusted vertically for the particular requirement for the comfort of the user, thereby increasing the accuracy and efficiency of the operator of the appliance mounted thereon.

Another object of the invention is to provide a device of this character which will be exceptionally sensitive in operation, to the end that the movable supporting; frame may be readily and easily raised or lowered, to a minute degree to insure the necessary adjustment for the convenience of the operator using the machine, mounted on the support.

With the foregoing and other objects in view which willappear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a plan View of an adjustable support constructed in accordance with the invention.

Figure 2 is a sectional View taken on line 2-2 of Fig. 1.

Figure 3 is a sectional view taken on line 3-3 of Fig. 4.

Figure 4 is an end elevational View of the device.

Figure 5 is a sectional view taken on line 5-5 of Fig. 4.

Figure 6 is a sectional view taken on line 6 6 of Fig. 4.

Referring to the drawings in detail, the device comprises a base section 5 and a vertically adjustable supporting section connected with the base 5.

The base section comprises a length of angle bar material constructed to provide a rectangular frame, the angle bar being arranged so that one section thereof extends inwardly in a horizontal plane, providing a track 'l and a vertical guard ilange 8.

Extending along the longitudinal sides of the base section, are angle bars 9 that have one of their flanges extended inwardly over the track 'I providing a guard rail for the rollers I that operate on the track. The angle bars 8 are secured in position by means oi the screws II that pass through registering openings in the angle bars 9 and the guard flange 8. The guard flange 8 prevents lateral movement of the rods I3, which rods provide supports for the rollers I0. These rods I3 have their inner ends disposed in sockets formed in the members I4 which are provided with transversely disposed threaded openings to accommodate the oppositely threaded portions I5 of the shafts I6, the inner ends of the shafts I6 being connected by means of the collar I1.

The shafts IS are arranged in pairs and are disposed in spaced relation with respect to each other, adjacent to the ends of the support.

The vertically adjustable supporting section 6 of the device embodies a metal plate of a length and width convenient to accommodate a typewriter, adding machine or the like. The plate is indicated by the reference character I8 and is provided with an upstanding flange I9 formed along its longitudinal edges and one end thereof. Angle bars 2G are secured to the sides of the vertically adjustable supporting section and overlie the edges of the plate I8 as clearly shown by Fig. 5 of the drawings.

Secured to the lower surface of the plate I8 and disposed adjacent to the ends thereof, are bearings 2l arranged in pairs, each pair of bearings providing mounts for the shafts 22 that are disposed between the shafts I6 at each end of the plate.

Secured to the rods I3 are toggle members comprising connected plates 23 which plates are formed with bearings 24 that accommodate the shafts 22 so that the plates 23 may move with respect to the shafts 22. The plates 23 are arranged in pairs, and are'so constructed that one plate of each pair is provided with a central cut-out portion to accommodate the tongue 25 of the cooperating connecting plate, so that transverse movement of the plate with respect to the shafts 22, will be prevented.

The shafts I6 have their outer ends extended through the end iianges of the base section 5 where they are supported in bearings 26 one end of one of the shafts being connected with the crank 21, by means of the pivot 28, so that rotary movement of the crank 2l will operate the shafts I6 to move the rods i3 of each pair of rods, towards o1' away from each other. It is obvious, when the rods I3 move towards each other, the upper ends of the connecting plates 23 will move upwardly, and when the rods I3 are spread apart, the upper ends of the plates 23 will belowered resulting in the raising and lowering of the vertically adjustable supporting section 6 to adjust the section S and typewriter or machine mounted thereon, so that the operator may conveniently operate the keys of the machine.

Because the crank 21 is pivotally connected with its shaft I6, it will be seen that the crank may be swung to the position shown in full lines in Fig. 3 of the drawings, and positioned under the clip 28, where it will be held out of the Way.

What is claimed is:

An adjustable support comprising a rectangular base constructed of angle bar material, angle bars secured along the upper edges of the base and providing side channels with the base, shafts having oppositely disposed threads, extending through the longitudinal center ofthe ba-se, a pair of transversely disposed rods, mounted at each end of the base, rollers on the ends of the rods, said rollers oper-ating within the channels, socket members having threaded openings, mounted on the transversely disposed rods at points intermediate their ends, said shafts being threaded in said socket members, toggle members comprising wide plates connected with the transversely disposed rods, an upper supporting member, transversely disposed shafts mounted on the supporting member and to which the upper edges of the toggle members are pivotally connected, and means for operating the shafts simultaneously, swinging the toggle members vertically, raising and lowering the upper sup porting member in a true horizontal plane.
