TYPE-WRITER SUPPORT.

To all whom it may concern:

Be it known that we, JOSEPH M. BAINER, HARRY R. SPURLING, and ARCHIE W. SPUR- LING, citizens of the United States, residing at Marysville, in the county of Union and State of Ohio, have invented certain new and useful Improvements in Type- Writer Supports, of which the following is a speci fication, reference being had therein to the accompanying drawing.

This invention relates to typewriter supports and the object of the invent-ion is to provide a support of this character which can be mounted beneath a desk of ordinary construction and will enable the typewriter to be depressed and moved into a position beneath the desk where it will not interfere with the usual use of the desk, or to be moved outward and upward into an operative position in front of the desk, thus avoiding the necessity of making a portion of the top of the desk movable, as is now customary, and enabling a solid top desk to be provided with a typewriter support.

To this end it is a further object of the invention to slidably mount a frame on the pedestals, or supporting members, of the desk and to mount a supporting platform on said frame in such a manner that it can be depressed and elevated.

It is also an object of the invention to provide such a support which can be readily attached to desks already in use without alteration thereof; and further, to, provide such a device which will be very simple in its construction and operation and of a strong and durable character.

In the accompanying drawings, Figure 1 is a front elevation of a typewriter support embodying our invention showing the same applied to a double pedestal desk; Fig. 2 is a transverse, sectional view of a desk showing the typewriter support in elevation and in a position to support the typewriter beneath the desk; and Fig. 3 is a similar view showing the typewriter support in a position to support the typewriter in an operative position.

In these drawings we have illustrated two embodiments of our invention. The main features of construction and operation in both forms are the same. In each instance the typewriter is supported in such a manner that it can be moved downward and rearward to a point beneath the desk where Specification of Letters Patent.

it will not interfere with the ordinary use of the desk. When it is desired to use the typewriter the same is drawn forward and I upward into an operative position and is retained in this position. In each form of the device here shown we have provided a supporting frame which is slidably mounted on the supporting members for the desk. In the present instance we-have shown the invention as applied to a double pedestal desk in which the pedestals constitute the sup porting members and the supporting frame is mounted on the inner walls of the pedestals. A typewriter supporting device, such as a platform, is mounted on the frame and is capable of vertical movement relatively thereto. Thus, the frame and the platform may be drawn outward and the platform then elevated to a position in front of the desk and at the proper level to support the typewriter at the desired height. In the two forms of devices here shown we have illustrated two of the many methods of carrying out the invention.

In Figs. 1, 2 and 8 we have shown the device applied to a flat top desk 1 comprising two pedestals 2 which constitute the supporting members therefor. A supporting frame comprising side bars or guide members 3 is slidably mounted on suitable tracks 4;, which, in the present instance, consist of bars rigidly secured in substantially horizontal positions to the inner walls of the pedestals at points near the upper ends thereof, the guide members 3 being grooved to receive the tracks 4. The device upon which the typewriter is mounted consists of a supporting plat-form 5, the forward portion of which is slidably and pivotally mounted upon the sliding frame. In the form here shown each side of the forward portion of the platform 5 has rigidly secured thereto a plate 6 provided with a longitudinal slot 7 into which extends a pin 8 mounted in the adjacent frame member 3. The rear end of the platform 5 is so supported from the frame that it is capable of vertical movement relatively thereto. As here shown, each side of the rear portion of the platform is pivotally connected to one end of a lever 9 which is pivotally supported from the sliding frame at a point below the frame members 3, upon which the forward portion of the platform is mounted. In the present instance each frame member 3 is provided with a depending bracket 10 on the lower end of which the lever 9 is pivotally mounted. The distance between the pivotal connections of the levers to the brackets 10 and their points of connection to the platform 5 is substantially equal to the distance between the pivotal centers of the levers and the upper portions of the side members 3. Consequently, when these levers are in a substantially vertical position with those'ends thereof which are connected to the platform 5 uppermost, the platform will be supported in a substantially horizontal position. When the position of the levers is substantially reversed the rear end of the platform will be depressed a considerable distance below the forward end thereofand the typewriter, which is mounted on the platform, will be depressed below the level of the top of the desk,thereby enabling the platform, and the frame 011 which it is mounted, to be moved beneath the top of the desk or to be withdrawn from beneath the same. The levers 9 extend some distance beyond their points of pivotal connection to the brackets 10 and are provided at their rear ends with a counterweight. In the present instance a single weight 11 is connected to the two levers. This weight tends to counterbalance the weight of the machine on the platform and to facilitate the operation of the supporting device.

lVhen the supporting device is in the position shown'in Fig. 2 and it is desired to use the typewriter, the forward end of the platform 5, which is near the front of the desk, is grasped by the operator and a forward pull exerted thereon. This will cause the frame as a whole and the latform which is carried thereby to move orward on the tracks 4 until the stops 12 carried by the frame members 3engage cooperating stops 13 on the supporting members for the desk. When the movement of the frame as a whole is checked a continued pull on the platform will cause the platform to move forward relatively to the frame, the slotted bars 6 sliding on the pins 8 mounted in the side members of the frame. This forward movement of the platform relatively to the frame causes the levers 9 to move about their pivotal centers and elevate the rear end of the platform, the weight 11 facilitating this movement of the platform and completing the movement after the rear end of the platform has passed a central position. After the levers 9 have assumed a substantially vertical position with the typewriter in a position to be operated a slight rearward thrust on the platform will throw the points of connection of the levers 9 to the platform 5 in the rear of the points of connection of those levers to the brackets 10. This rearward movement of the platform may be limited in any suitable manner. If desired the typewriter itself may engage the front edge of the desk and when the typewriter is in this position it will be apparent that the platform is locked both against rearward movement and against downward movement and a rigid support is provided for the typewriter. To return the typewriter to its idle or inoperative position the platform 5 is given a slight forward pull to move the upper ends of the levers 9 in front of their points of connection to the brackets 10 and then the forward edge of the platform is moved upward and the rear end depressed. When the platform 5 has assumed the position shown in Fig. 2 the frame as a whole is pushed rearward and the typewriter and its supporting devices moved into position where they will not interfere with the use of the desk as such. Owing to the inclined position of the platform 5 a comparatively small amount of sliding movement will place the same in a position where it will not interfere with the ordinary use of the desk.

It will be apparent that the device is a very simple one, very easy to operate and will support the typewriter either in an operative position or in such a position as to offer no interference with the use of the desk for ordinary purposes. It will further be apparent that this device is of such a character that it can be very readily attached to solid top desks already in use without altering said desks in any manner whatever.

lVhile we have shown and described two embodiments of the invention it will be understood that these are shown for the purpose of illustration only and that we do not wish to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is
