HENRY S. WAITE, OF COLUMBUS, OHIO.
TELEPHONE-BRACKET.
SPECIFICATION formingv part of Letters Patent N 0. 746,210, dated December 8, 1903.
Application filed February 20, 1903. Serial No- 144,292' (No model) I To all whom it may concern:
Be it known that I, HENRY SWAITE, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Telephone Brackets, of which the following is a specification.
While I have shown for the purposes of illustration a telephone-bracket embodying my invention, it is of course obvious that my invention may be utilized in all brackets where the feature of adjustability is desirable.
My invention consists of a shelf and a support connected together by means of a lazytongs, the ends of the lazy-tongs being ful-' crumed to said support and to said shelf, and means intermediate the fulcrums to limit the extension and collapse of the lazy-tongs and at the same time insure a horizontal position and thrust of the shelf. v i
The object of my invention is to construct a device of this character that will be simple and cheap of manufacture; and with these and further objects in view my invention consists of the parts and combination of parts as will be hereinafter more fully set out..
In the drawings, Figure l is a side elevation of a telephone-bracket embodying my invention. Fig. 2 is a similar view showing the bracket extended. Fig; 3 is a top plan view of Fig. 2. Fig. 4 is a top plan View of Fig. 1, parts being broken away.
1 represents a support provided with a hinged member 2, havinga series of screwopenings 3, whereby said support may be secured to a Wall, desk, or other structure.
4 represents for purposes of illustration a shelf adapted to hold a telephone, said shelf being provided with suitable curved lugs 5, integral therewith, and an elongated slot 6, in which is adjustably mounted a lug 7, having a depending nut-threaded shank 8, on
' which is mounted a set-screw 9, whereby said together by means of the lazy-tongs 11. The respective ends of the lazy-tongs are disposed toward one another, being fulcrumed independently,-as at 12, to the'lug 10 of the shelf 4 and to said support. 1, in addition to which said tongs has the usual fulcrum 13. The arms 14 of the lazy-tongs are provided on their ends with a segmental rack 15, the racks of the adjacent arms 14 intermeshing one with the other, as clearly shown in the several figures, thus sustaining the shelf in a horizontal plane and the lazy-tongs in a horizontally-extended position, thereby obviating any tendency of the tongs to sag.
16 is a'disk pivotally mounted onthe fulcrum 13 of the lazy-tongs, the face of which is adapted to bear a suitable inscriptionsuch, for instance, as an advertisement while the rear of the disk is provided with integral lugs 17,which project between the long levers of the lazy-tongs, as shown in Fig.2. As seen in Fig. 1, these lugsl7 limit the collapse of the lazy-tongs by reason of their ongagement with the lug 10 on the shelf 4 and the support 1, the periphery of the disk overlapping said support and lug, as shown more clearly in Fig. 4. A further object of the lugs 17 is that they eliminate unnecessary strain upon the segments 15 when the lazy-tongs is in its extended position, by reason of the fact that the long levers of the lazy-ton gs impinge on each side of them, as shown in Fig. 2. The lugs also prevent the bracket being extended too far. I
- Having thus described my invention, What I claim as new therein, and desire to secure by Letters Patent, is
1. A lazy-tongs having the lovers at both ends disposed toward one another and pivoted independently of each other, and intermeshing racks on the respective ends of said independently-pivoted levers.
2. The combination with the support and the bracket of a lazy-tongs having the levers at both ends disposed toward one another and pivoted independently of each other, and intermeshing racks on the respective ends of said independently-pivoted levers, one pair of the end levers of the lazy-tongs being pivoted to the bracket and the other pair being pivoted to the support.
3. The combination with a hinged support and a shelf, of lazy-tongs fulcrumed on said shelf and support, segmental racks interposed between the fulcrumed ends of the t0ngs,a disk secured to the main fulcrum of the tongs, and lugs projecting from said disk between the arms of the tongs.
4. The combination with a hinged support and a shelf, a lug cast integral with and at right angles to said shelf, of lazy-tongs fulcrumed at their ends to said support and t0 the lug of said shelf, segmental racks integral with the ends of said tongs and intermeshing between the end fulcra, a disk secured to the main fulcrum of the tongs, and lugs projecting from said disk, between the arms of the tongs.
The foregoing specification signed this 12th day of February, 1903.
H. S. WAITE.
