Specification of Letters Patent.

Patented March 31, 1908.

Application filed August 8, 1906. Serial n6. 329,789.

To all whom it concern:

Be it known that I, WILLIAM FEToH, citizen of the United States, residing at Supports, fication. v

The object of the present invention is to provide an improved supporting device for typewriters which is ada ted to be secured to the lower face of any 0 the ordinary types of desks or tables in common use, and which operates to hold the typewriter in a convenient position for use, or back against'the lower face of the desk top.-

A. further objectisto provide. a device of this character comprising 1' few and simple parts which are designed to withstand hardusage and operate efliciently under the most trying circumstances.

In general the device comprises a shelf supported by a pair of swin in arms which are pivotally connected to 518 ower face of the desk top and are adapted to be swung either inwardly or outwardly to hold the" shelf upon whlch the ty ewrlter sets either in an operative or out-o -the-way position.

For a full description of the inventlon and the merits thereof and also to acquire a knowledge of the details of construction of' the means for eflectin the results, reference is to be had to the fol owing description and accompanying drawings, in which:

. Figure 1 is an end view of a desk having the typewriter support appli d thereto, porclearly illustrate the invention;' Fig. 2 is a similar view showing the typewriter as swung back under the rear portion of the desk top and in the position assumed when not in use; Fig. 3 is a transverse sectional view on the line 33' of Fig. 1 Fig. 4 is a similar view on the line 4-4 ofFig. 1; Fig. 5 is a perspective view of the typewriter su ort when detached from the desk} and, ig. 6 is a detail perspective view of the upper portion of one of the locking arms and a portion of one of the rods connecting the corresponding looking arms.

Corresponding and like parts are referred to in the followin r description and indicated in all the viewso the drawings by the same reference characters.

elng broken away to more are rigidly secured to the lower face of an su'itable horizontal support such as the desk top 2 and to which the swinging arms 3 are pivoted. In the specific construction of the rackets 1, it will be observed that they have an angular formation and comprise two N .The numerals 1 designate brackets which flanges arranged at approximately right angles to each other, one of the flanges 5 fitting against the lower face of the desk to and serving as a means by which the brac et is secured thereto, while the opposite flange 6 rojects downwardly and serves as a su .port or the swingin arms 3 to which the slielf 4 is attached. T e two downwardly project-J mg flanges 6 of the brackets are connected by the shaft-'7 which pass through openings therein and have the swinging arms 3 connected to the opposite ends thereof. The swinging movement of the arms 3 which are pendent from the brackets 1 enables the shelf 4; upon-which the typewriter is mounted to be swung either rearwardly under the desk top or horizontal support 2 when not in use, or forwardly so as to project beyond the desk top, as shown in Fig. 1.

Owing to the fact that the pendent arms 3. upon each side of the support are spaced from each other and approximately parallel,

it will be apparent that the shelf 4 will re-' main in a horizontal position throughout the entire swinging movement. the typewriter, fixed at either limit of the swinging movement, locking members 8 and 9- are employed, the former being located at the forward endof the brackets 1 while the latter are located at the rear ends. These locking members have primarily a hooked In order to hold formation and are adapted to on age with lugs 10 projecting from one pair of t e arms 3. The upper ends of the locking members 8 and 9 are provided with the lateral projections 20, the ends of which are reduced in section, as seen at 11 to form stub-shafts which 0 erate in suitable bearings in the flanges 6 of the brackets 1 and serve as a means for pivotally mounting the locking arms. These lateral rojections 20 upon the locking members have the angular openings 12 formed therein, and each pair of locking members is connectedb a rod 13, the ends of which have an angular fbrmation as seen at 14 and fit within the angular openings 12 in the lateral rojec- .tions 20 at the upper ends of the ocking l hold the shelf 4 at either limit of its swinging by the bar 15, one end of the said bar projecting forwardly and being provided with .the knob or finger-piece 16.- In order to hold the locking members 9 in a forward position where they will readily engage with the lugs 10 to movement, coil springs 17 are employed, the said springs having one end connected to brackets 1, while their opposite ends are se cured to the rear locking members 9. It may be found desirable to employ stops for limiting the forward movement ofthe locking members and for this purpose, tongues 19 are shown as stamped from each of the flanges'fi knob 16 rearwar and 9 will be moved so as to dlsenga e the of the brackets 1 and bent outwardly so as to en age the arms 9.

n the operation of the device, it will be apparent t at by ushing the finger-piece or the locking members 8 lugs 10 and cause the typewriter to fal and swing toward the reverse position.

In the practical construction of the device, the rear locking members 9 are formed somewhat longer than the forward looking mem-v bers 8 so that when the typewriter is released from its forward or operative osition, as shown in Fig. 1, it will swing to t e rear and throw the In s 10 into engagement with thelocking mem ers 9 without any external assistance. The path of the lug 10 is indicated by dotted lines in Fig. 1 and it will be apparent that upon the rearward swin of" t e supporting arms 3 the against the vertical end portion of the locking member 9 and also force the same rearwardly until the lug 10 is engaged by the hooked end of the said locking member. Upon the reverse movement of the typewriter, or that from the osition shown in Fig. 2 to that shown in ig. 1, it will ordinarilybe re uired to give the typewriter a slight 11ft in or er to cause the arm 8 to on age with the lugs 10.

Y Havin thus descri ed the invention, what is claime as new is:

1. In a device of the character described, the combination of a support, swinging arms pendent from the support, a shelf carried by the swinging arms, and catches pendent from the support anddesigned to hold the shelf either in an operative or inoperative position.

2. In a device of the character described, the combination of a support, swinging arms connected to. the support, .a shelf carried by the swinging arms, catches mounted upon the support and designed to lock the shelf in an operative or inoperative osition, and an operatinlg bar connecting t e catches.

3. n a device of the character described,

said lug wil strike the'combination of a support, swinging arms connected to the sup ort, a shelf earned by the swinging arms, 2. ug projecting from one of the swinging arms, and swinging catches carried by the su port and designed to engage the lug to 100 the shelf either in an operative or-inoperative position.
