UNITED STATES PATENT OFFICE.

LED GER STAND.

Application filed March 24, 1924. Serial No. 701,485.

To all whom it may concern.-

Be it known that I, CLYDE Evnnnr'i BROOKS, a citizen of the United States, and

a resident of Mason City, county of Cerro Gordo,'State ofIowa, have invented a new and useful Improvement in Ledger Stands, of which the following is a full, clear, and exact description.

My invention relates to improvements in ledger stands, and more particularly to that type of stand which is adjustable as to height, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a ledger stand of the type described by the use of which the necessity of lifting lodgers from one support to another is entirely obviated. Certain ledgers employed in ofiices weigh in the neighborhood of fifty-five pounds, and are too heavy and cumbersome to be lifted about freely, as in moving the ledger from one side of a posting machine to the opposite side, and at a different height from the floor.

A further object of my invention is to provide a device of the type described which will remain in its adjusted position and in which the platform for supporting the ledger may be elevated or lowered with ease.

A further object of my invention is to provide a device of the type described in which means for adjustment as to weight of the ledger supported thereupon is provided.

A further object of my invention is to provide a ledger stand of the type described in which means is provided for maintaining the platform in a stable condition at all times.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accom" panying drawings forming part of this application, in which- Figure 1 is a front elevation of an embodiment of my invention, and

Figure 2 is a side elevation of the mechanism illustrated in Figure 1.

In carrying out my invention I make use of a base member 1 supported upon suit-' able casters 2. A collapsible frame consisting of a pair .of Ushaped members 3 and 4, pivotally supported upon the base 1 at .5,

(see Figure 2) has pivotally connected thereto complementary frames 6 and 7- respectively upon which the ledger platform 8 is supported. The pivotal connection of the

frames

3 and 6 and 4 and 7 is indicated at 9, (see Figure 1). The connection between the platform 8 and the upper ends 10 of the frames 6 and 7 consists in a U-shaped hanger securedto the undersurface. of the platform 8, and pivotally connected at 12 with the adjacent ends 10 of the frames 6 and 7.

In order that the platform 8 may be stable at all times and not tilt upon its relatively narrow support 12l2, a pair of collapsible guide members 13 is provided and connected on each side of the frames 36 and 3'7, (see Fig. 1). These collapsible guide members consist of a pair of frames 14: pivotally connected to one another by a hinge 15 pivotally connected at their ends by hinges 16 to blocks 17 secured to the under side of the platform 8 and tothe upper side of the base 1 respectively. The

hinges

16 and 15 are sufficiently wide to prevent any tilting of the platform 8, yet to not interfere inany way with the vertical elevation or lowering of the platform.

Resilient means for normally elevating the platform 8 is provided in tension springs 18 secured at their uppermost ends to rods 19 carried by the lowermost portions of the frames 6 and 7 respectively. The opposite ends of the tension springs 18 are connected to blocks 20 at the opposite sides of the base 1 to which the frames 6 or 7, connected with the upper ends of the springs 18, are associated. These blocks 20 are provided with a threaded bore therethrough, through which a shaft 21 having right hand threads for the remaining block is disposed. The shaft 21 is provided with a crank handle 24: by means of which the shaft may be rotated to vary the tension of the springs 18.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Let us assume that a ledger is placed upon the platform 8 and that it is desired to post this ledger. In posting the ledger it is preferable to place the ledger on the right hand side of the posting machine and about 30 inches from the floor. After the item has been posted, the entire stand is moved upon its casters 2 to the left hand side of the post ing machine for proving. In proving the ledger it is usually necessary to have the ledger higher from the floor, approximately 89 inches instead of 30. Heretofore it "has been necessary to lift the heavy ledger to a higher supporting surface; \Vith my improved support, however it is merely necessary to lift up on the platform S/The springs 18 will assist in this movement and prexY ent collapse of the frames 36 and If the ledger is a particularly heavy one, the tension of the springs 18 will be in creased, While if it is a light one,"it maybe decreased. This increase and decrease in the tension of the springs 18 is brought about by rotation of the shaft 21 by means of its crank 2 k.

1 claim:

1. A ledger stand of the characterddescribed comprising a base member, a ledger supporting platform; a collapsible means comprising a pair of frames pivotally connected with one another and with said base member and said ledger supporting platform respectively, spring means associated with said collapsible means for yieldingly elevatingsaid'platform, and a pairof frames pivotally mounted to each other and to said platform and sa1d base respectlvely, and

"having the-ir'axes disposed transverse to the axes of said collapsible means, whereby said base member and said platform are maintained substantially parallel at all times.

2. A ledger stand of the character de' scribed comprising a base member, a ledger supporting plat-form, a collapsible mea-ns comprismg'a pair'of frames pivotally con-- CLYDE nvnan'rrnnooris.
