COLLAPSlIBLE VIBRATION-ABSORBING SUPPORT.

Specification of Letters'latent.

Patented Mar. 29, 1921.

Application filed November 8, 1917. Serial No. 200,961.

T 0 all whom it may concern:

Be it known that I, GEORGE W. BEADLE, a citizen of theUnited States of America, and a resident of New Rochelle, New York, have invented a new and useful Improvement in Collapsible Vibration-Absorbing Supports, which invention is fully set forth in the following specification.

This invention is intended primarily for supporting phonog'raphs when in use upon railway trainsor automobiles, but may be used for typewriting-machines and in other service where the instrument-is to be pro tected from the jolts or jars due either to travel or to the vibrations'of near-by machinery, etc.

The invention comprises broadly a framework carrying and positioning a plurality of shock-absorbing devices. More specifically the invention comprises two cross-arms centrally pivoted together, and carrying at their ends suitably-cushioned seatsfor the corners of the phonograph or other device to be supported, and provided also with suitable cushioning-devices to rest upon a table or other support without i'njuryto the latter. The invention also comprises the feature of constructlon and arrangement hereinafter set forth and claimed.

The invention may be embodied in' different concrete forms but for the sake of clearness the following specification and the accompanying drawings set forth one pre-' ferred embodiment for use with the com-- mercial dictation-machine known as the dictaphone. In said drawings? Figure 1 represents a front elevation o the device, the phonograph being conventionally indicated in outline only;

Fig.2 is a plan of the same dev1ce,the

' phonograph being removed; and

cpeni in the same horizontal plane. there willbe a definite predetermined limit Fig. 3 represents, on a larger scale, a detail is seated with its four corners resting 1n the work consists of the two cross-arms 1 and 2,

shown as two flat horizontal bars, pivoted together at their center, as b a rivet 3; and near each end of one memi ier (as 2) is an offset 4, so that all four'outer ends will lie Preferably for the movement of' the two arms when n as byacurved slot-5 in one member :7 and a d ependlng p1n6 in the other -at being" understood that when opened into their predetermined extreme positions (as indicated in Fig. 2), the four ends of the arms will be properly positioned for receiving the four corners of the particular phonograph (or other instrument for which the particular framework is designed).

Above the end of each arm is secured a boss 7, preferably circular; and beneath the same is secured a cushion 8, preferably of rubber, suitably held in place as by a headed screw 9 passing through a washer 10 and threaded into the end of the cross-arm (and into its boss also, if desired).

One or more convolutions of the lower end of a comparatively-stiff upright helicalsprin 11 are engaged snugly around the boss where they are secured in place in any suitable manner, as by solder. The

upper. end of each springll carries a seat 12 for one corner of the dictaphone. This seat is shown as a substantially-rectangular plate having aroundtwo sides an upturnedflange, to provide a three-sided concave corner to fit the convex corner of the dictaphone; and the central portion of said seat is cut awa to leave an aperture 13 with a plurality o integral fingers 14, here shown as three in number, which are then bent down to engage within the helix of the spring 11, where they are suitably secured to the spring, as by being bent slightly around the wire constituting the convolutions thereof, or by solder or the like.

In. traveling, and for shipment, the two arms are folded up as near parallel as possible, so as to occupy less-space than when opened out. In order to use the device, the arms are opened out as far as the slot and pin (5 and 6) will permit, as indicated in ig. 2, and then placed on a table or other suitable support; and then the phonograph ducing sounds. a

One form of the invention has thus bee described with full detail, but only for the sake of clearness, since the invention is not limited to the precise construction and arrangement here set forth, but might be embodied in various forms, and parts might be transposed or inverted or otherwise modified within the spirit of the invention. For instance, although the drawings show the framework made up of two arms centrally pivoted together, yet it is obvious that they might be pivoted otherwise than centrally, and that there might be a greater number of arms than two; also that the shock-absorbers might be provided at only two of the adjacent corners of a rectangular device, reliance being had upon the lateral rocking thus provided for absorbing some part of the shock. But the symmetrical form set forth, with the two centrally-pivoted cross-arms and the four shock-absorbers, is believed the most desirable arrangement.

The invention having been thus described. what is claimed is-- 1. In a collapsible support, the combination with two pivoted cross arms, of vibration-absorbing means at each terminal thereof, each said means comprising a cushion and boss secured on opposite sides of the terminal, an upright helical spring secured to said boss, and a centrally apertured cor-c ner-supporting seat resting upon said spring and having downturned fingers secured to the same.

In a shock-absorbing support, the combination of a pair of members pivoted together between their terminals, means carried by each terminal comprising on one side thereof a cushion pad and on the other side a spring and an article receiving cap mounted on the spring, and a single means for maintaining the pad and spring in axial alinement.

In a shock-absorbing support, the combination of a pair of members pivotcdtogether between their terminals, each terminal being provided with a block on its upper side, a solid cushion on the other side of the terminal beneath said block, means passing through the cushion and the terminal into the block for securing the three members in fixed relation, a coil spring centered over said block. and an article-receiving cap supported by said spring.

in testimony whereof I have signed this specification in the presence of a subscribing witness:

GEORGE W. BEADLE.
