TYPEWRITER FASTENER.

Application filed November 14, 1921. Serial No. 514,970.

To all whom it may concern Be it known that I, FRANK B. TERNEs, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have invented a certain new and useful Typewriter Fastener, of which the following is a specification.

It has heretofore been proposed to fasten typewriters to the tops of desks, to revent the typewriter from shifting aroun espe cially when the top of the desk is swung from a horizontal position, to a concealed position. Typewriter fastening devices, such as have been placed on the market are not satisfactory for various reasons, among which are the high cost and the unsatisfactory connection of the typewriter to the fastener.

It is an object of the present invention to provide a typewriter fastener which is of low cost and may be applied to a desk or table top at a very small expense and without requiring the passing of a fastening screw up through a hole drilled therefor through the table or desk top.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be made manifest in the following description of the preferred form of the invention, which is illustrated in the drawings accom anying and forming part of the specification. It is to be understood that it is not intended to limit the invention to the embodiment shown by the said drawings and description, as variations may be adopted within the scope of the invention as set forth in the claim.

Figure 1 is a perspective of a top of a typewriter desk having a folding section and to which the improved fastener is shown applied.

Fi 2 is a perspective of the fastener in detai Fig. 3 is a side elevation of a fragment of r a typewriter of well known make, illustrating its attachment to the improved fastener which is secured to a desk top.

Fig. 4 is a perspective showing a male fastening element attachable to the typewriter frame and engageable with the fastener.

The fastener, as shown, is made of resilient strip material such as steel or brass and having at one end a base plate 2, which may be provided with one or more apertures 3,

to receive a fastening screw 4, which may be screwed into the top T of a table or desk of any kind and which is shown in Fig. l, as of the folding typewriter table type. At the forward end of the base 2 thereis an upstandlng spacing or shank part 5, and from the upper end of this there is bent angularly a bifurcated member having tongues 6-6, whose outer ends 7 may be turned up wardly slightly, and which are rounded off. as at 8, at the end edges to facilitate engage ment of the typewriting machine M. Between the parallel tongues 6 there is provided a presser finger 9, which is bowed or recessed down at its central portion, while its outer end is provided with a curved upper striking end 10; the upturned ends 7 of the tongues 6 and the downturned end 10 of the finger 9 providing for the facile attachment of the machine to the fastener.

Such attachment may be secured by the provision upon or attachment to the frame of the machine M, of any desirable complementary part or element to interlock with the resilient limbs of the leaf. Such a complementary fastening part may consist of a flat-head screw 11, set in the usual tapped hole 12, provided in the lower edge of the typewriter frame. Such a type of screw has a head which will project below the bottom edge of the frame and when the latter is shifted toward the resilient ends of the tongues 6 and finger 9, these will separate at their divergent ends and the head of the screw may be pushed inwardly to lie above the bowed body of the finger 9.-

After the typewriter has been pushed in place over the fasteners, of which one is provided for both the right and left sides of the frame, the engaged projecting portion, as the head of the screw 11, is resiliently retained by the finger 9, whose upturned end 10 prevents ready dislodgement of the machine forwardly from the fastener, but allows the machine to be withdrawn when sufficient force is applied to overcome the holding tendency of the resilient tongues and finger between which the heads of the screws 11 are clamped. It is understood that the amount of projection of a screw 11 may be readily determined and it may be then set or locked in its required position through the means of an ordinary locknut 13 on the body of the screw, as in Fig. 4:. In this figure 8. form of the machine attachment consists in a screw l1 having an elongated head 11", although I have found it is sufficient to use an ordinary flat-head screw, as shown at 11.

- When only one screw hole 3 is used in the base 2, which is preferable because it eliminates attachment screw holes in the table top, tendency of the base to rotate about its screw may be overcome by any suitable means, as for instance, by striking down a V-sha ed tooth or prong 2 which may be provided to one side of the screw hole 3.

This, it will be seen, necessitates the boring of but two screw holes in the top .1 of the desk and the use of but two screws.
