3 Claims.

This invention relates to a device for fastening a typewriter to a desk or table and has for its principal object the provision of a device of this character which will enable a typewriter to be attached to a desk by simply pushing it into place thereon; which will positively and securely hold the typewriter in position while in use or when the desk is folded; and which will allow the typewriter to be instantly lifted from the desk without requiring tools or manual operations of any kind. I

The invention is particularly valuable in schools and the like where the various types of typewriters are constantly interchanged to give the students experience on the various kinds. It is, of course, not limited to this particular use but will be found valuable wherever both portability and secure mounting are desired.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and EfilClBIlCY. These will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part thereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a plan view of the typewriter platform of a typical desk, illustrating the fixed members of the improved fastener in place thereon;

Fig. 2 is a side view of a typewriter in place on the desk illustrating the invention in use thereon;

Fig. 3 is a bottom view of a typical typewriter with the portable portion of the fastener in place therein;

Fig. 4 is an enlarged cross section through the foot of a typical typewriter illustrating the position of the portable portion of the fastener thereon;

Fig. 5 is an enlarged plan view of one extremity of the portable portion;

Fig. 6 is a fragmentary, horizontal section, taken on the line 6--6, Fig. 4, illustrating the method of connecting the fixed and portable portions of the fastener; and

Figs. 7 and 8 are side and top views, respectively, of the fixed portion of the fastener.

In the drawing a typical typewriter desk is indicated at I0 with its typewriter supporting platform at I I. A typical typewriter is illustrated at I2.

The usual typewriter is provided with cupped,

cushioned feet I3 carried in a flanged foot cup It, the entire assembly being secured to the'typewriter by means of attachment screws I5. The foot cup I4 is formed with projections I5 which extend into suitable openings in the base of the typewriter to prevent the feet from rotating thereon.

This invention consists of a portable portion which is secured permanently to the typewriter and a fixed portion which is permanently secured to the desk. The portable portion comprises a cross bar I! preferably of sheet metal and bent longitudinally to approximately a 2 cross section, that is, it has an upper, flat, horizontal flange I8 and a lower, flat, horizontal flange I9 separated vertically by means of a vertical portion 20. The flange I8 is preferably Wider-than the flange I9, as illustrated.

Two spear-shaped latch tongues 2I having side locking notches 29 are secured to the vertical portion 29 of the cross bar I! by means of suitable rivets 22, one tongue being positioned adjacent each extremity of thecross member I'I immediately above the lower flange I 9.

Adjacent each extremity, the upper flange I8 is perforated with a screw hole 23, for the passage of the attachment screw I5, and with an enlarged hole 24, for the passage of the projections It. The cross bar I I is secured to the typewriter I2 by removing the front feet therefrom and placing them on the cross bar, as illustrated in Fig. 4. The attachment screws I5 are then replaced to clamp both the feet and the cross bar in their proper positions. In placing the cross bar on the typewriter the lower flange I9 is directed toward the rear of the typewriter.

The fixed portion of the attachment comprises two metallic spring clips 25, each consisting 'of a blanked piece of resilient sheet metal bent upwardly at its opposite sides to form two forwardly extending spring arms 26 which normally extend first inwardly toward each other thence curve outwardly to form flared extremities, as shown in Fig. 8. The two spring arms 26 are positioned above the bottom of the clip 25, as indicated at X Fig. '7. The blank is perforated, as shown at 21, to receive suitable attachment screws 28 by means of which the two clips are attached to the typepushed rearwardly, the lower flange entering the space X under the arms 26 and the tongues 2| entering between the spring arms 26 until the latter snap into the locking notches 29 of the tongues, as shown in Fig. 6. The typewriter is now firmly held in place. It cannot bounce, vibrate, or move in any direction while in use. To remove the typewriter, it is simply pulled forwardly until the tongues 2| snap out of the resilient holding arms 26.

On a folding typewriter desk, as illustrated, when the desk is folded the rear of the platform I I descends swinging the typewriter to a substantially vertical position. In such a position, the weight of the typewriter is carried on the lower flange l9 which is securely hooked to the spaces X so that the suspension of the typewriter does not depend upon the strength or resiliency of the spring arms 26.

The device is adaptable to any type of typewriter or similar appliance. The only change which might be necessary is in the position, size and arrangement of the perforations 23 and 24 to .suit the particular type of machine to which the cross bar is to be attached. The spacing of the tongues in all types of cross bars will be identical so that various types of typewriters and other machines can be exchanged on the same desk or platform. The clips 25 are similar for all types of machines and all types of desks or tables.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent l. A typewriter fastener comprising: a cross bar; an upper, longitudinally extending horizontal portion on said cross .bar; a lower, longitudinally extending, horizontal portion on said cross bar projecting oppositely from the upper portion; a vertical portion connecting the two horizontal portions; means for securing the upper, horizontal portion to a typewriter; spacedapart latch members carried by said bar; latch receiving members; and means for securing said receiving members to a supporting platform, said receiving members being positioned above said platform to allow the lower; horizontal portion of the cross bar to pass therebeneath.

2. A typewriter fastener comprising: a cross bar; an upper, longitudinally extending, horizontal portion on said cross bar; a lower, longitudinally extending, horizontal portion on said cross bar projecting oppositely from the upper portion; a vertical portion connecting the two horizontal portions; means for securing the upper, horizontal portion to a typewriter; spearshaped latch tongues projecting rearwardly from the vertical portion; resilient tongue engaging clips engaging said tongues; and means for securing said clips to a supporting platform, said tongues being positioned above said platform to allow the lower, horizontal portion of the cross bar to pass therebeneath,

3. A typewriter fastener comprising: a cross bar; an upper, longitudinally extending, horizontal portion on said cross bar; a lower, longitudinally extending horizontal portion on said cross bar projecting oppositely from the upper portion; a vertical portion connecting the two horizontal portions; means for securing the upper, horizontal portion to a typewriter; spear-shaped latch tongues projecting rearwardly from the vertical portion; resilient tongue engaging clips engaging said tongues; and means for securing said clips to a supporting platform, said tongues being positioned above said platform to allow the lower, horizontal portion of the cross bar to pass therebeneath, the upper portion of the cross bar being positioned between the bottom of a typewriter and the front feet thereof.
