COPY HOLDER. APPLICATION FILED JUNE HM 3915- 2 Shins-SHEET 2- Patented May 29, 1917-.

detachably maintaining the LESLIE WARFEL, OF DUBOIS, PENNSYLVANIA COPY-HOLDER.

Specification of Letters Patent.

Patented May 29, 1917.

Application filed June 10, 1915. Serial No. 33,241.

To all whom it may concern.

Be it known that I, LESLIE WARFEL, a citizen of the United States, residing at Dubois, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Copy- Holders, of which the following is a specification.

My invention relates to adjustable supports and more particularly to a copy holder.

The primary object of my invention resides in the provision of a novel holder preferably detachably associated with any of the standard typewriters, the holder receiving the copy of the work that is being typewritten and being adjustable so that the co of the work will at all times be maintamed in the line of vision of the operator while operating the machine. 7

Another object of my invention resides in the provision of a novel means for adjustably associating the copy holder, or .platform, on a supporting standard.

Another object of my invention resides in the provision of a novel clamping means for supporting standard for the holder in a substantially rigid position with respect to a support or the frame of a machine.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, efficient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of Fig. 4 is an enlarged fragmentary rear elevational view of the copy holder illustrating to advantage the slotted angle iron, which constitutes an efiicient means for procuring an adjustment of the holder;

Fig. 5 is an enlarged top plan view-of the clamp;

Fig. 6 is a transverse sectional view taken through the standard on the line 66 of Fig. 2 and looking in the direction in which the arrow points.

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts throughout the different views, I provide a preferably tubular supporting standard 1 having the lower end thereof preferably solid and bifurcated to provide spaced threaded extensions 2, about which is rotatably and removably mounted the annular collar 3having a substantially trian lar shaped clamping foot 4, the collar eing formed at the apex thereof. This foot serves as an eflicient means for detachably maintaining the standard in a substantially rigid position with respect to a support. The support in this instance is preferably a portion of the base of a typewriter 5 and the substantially rigid position is maintained through the instrumentality of an elongated threaded end bolt 6 removably mounted in corresponding and diametrically opposed openings 7 in the collar. The bolt however, is not applied until the foot has been adjustedion, the threaded extensions. Aftenthe adjustment is obtained, the bolt engages the openings and is also positioned through the bifurcation and it is readily apparent that when the extreme free end of the bolt engages the base of the typewriter 5 cooperating with the upstanding flange 8 on the foot for maintaining engagement with the base, any accidental rotary movement of the standard is prevented. Because of the fact that the outer surface of the bolt is arranged in close relation with the inner sides of the threaded extensions 2,the maintenance of the standard in a vertical position is greatly facilitated. A thumb piece 9 is formed on one end of the bolt 6 for facilitating the operation thereof.

In order to brace the standard and thus increase the efficiency of the same, I have arranged longitudinally therein a partition 10, securable to the inner bore of the standard through the medium of oppositely extending securing flanges 11 and suitable fastening devices 12.

The upper end of the standard is closed by a socket member 13 arranged preferably centrally therein and receiving for rotary movement a swivel 14, the latter in turn adjustably supporting the copy supporting platform 15.

The copy holder or supporting platform is preferably rectangular in plan and has one longitudinal edge thereof bent upwardly to provide a supporting flange 16 for the copy or othermatter disposed v thereon.

For the purpose of providing an efficient means for adjustably supporting the copy holder on the swivel, I have provided an angle iron 17, one portion of which is rigidly connected to the rear surface of the holder through the medium of suitable fastening devices 18. The opposite or angularly projecting portion is provided with a longitudinal slot 19 and receives a bolt 20, the latter being carried by the spaced arms 21 formed by slitting the upper end of the swivel 14. In order to maintain the arms in frictional engagement with the sides of the angularly projecting portion of the angle iron 17, after the desired adjustment of the copy holder is obtained, a thumb screw 22 mounted on the bolt 20, is rotated and tightened. It is obvious that by loosening this thumb screw the position of the copy holder can be varied, at the will of the operator.

Although I have shown and described the preferred embodiment of my invention, I desire to be understood that I am not to be limited to the exact structure shown. However, great stress is laid upon the peculiar arrangement and manner of connecting the standard and foot and consequently securing the foot to the support for maintaining the standard in a substantially rigid position. Attention is also directed to the improved means for mounting the copy" holder can easily be seen that I have provided a device that is simple in. construction, con- 1. A support including a supporting standard, a clamping foot adjustably mounted on the standard, and common means passing through the foot and the standard for preventing the movement of the foot on the standard and for cooperation with the foot for removably securing the standard to a main support.

2. A support including a supporting standard havin a bifurcated end, a clamp- .ing foot rotata ly and adjustably mounted on the bifurcated end of the standard, a flange formed on the free end of the foot, and common means for engaging the foot and the standard between the bifurcations for preventing movement of the foot and for ootiperating with the flange for removably holding the standard in a substantially rigid position on a main support.

3. A support including a supporting standard having the lower end bifurcated to provide threaded extensions, a collar threaded on theextensions, a triangular foot integral with and extending laterally from the collar, a flange formed upon the free. end of the foot, and a bolt engaging the collar and pass'ingbetween the extensions for preventing movement of the foot when adjusted and for cooperation with the flange for re- -movably holding the standard in a substantially rigid position on a main support.

In testimony. whereof I afiix my signature in presence of two witnesses.

LESLIE WARFEL.
