Aug. Z8, 1934. A. G. BRADFORD DIAL TELEPHONE ATTACHIENT Filed )larok 15 Patented Aug. 28, 1934 UNITED @TATES PATENT @FFICE i? @laissa This invention relates to dial telephone attachments, and 1more particularly an attachment which embodies a flash light for illuminating the dial and a magnifying glass. d The primary object of the invention is to Vprovide a device of this type which is of simple and economical construction, and which can be readily clamped onto the telephone base in surrounding relation thereto.
A further object of the invention is to provide a magnifying glass support which enables ready vertical adjustment of the glass and which also permits of the glass being easily removed for use in reading of the directory in locating telephone 15 numbers or otherwise, and like replacement.
1n the drawing:
Fig. il is a perspective view of the invention, as in use;
Fig. 2 is a front elevation of the device, with .20a the magnifying glass removed;
Fig. 3 is a side elevation of Fig. 2;
Fig. 4 is a detail fragmentary top plan view of the attaching means for the glass; and
Fig. 5 is a section on line 5--5 of Fig. 1.
In proceeding in accordance with the present invention, a base clamp 1 is employed which is of substantially C-shape and is formed of spring metal of approximately U-shape in cross-section, solas to engage over and about the base B of the 30 dial. A standard or arm' 2 is secured at its lower end to preferably the center of the clamp and at its upper end has one end lof a substantially C-shaped clip 3 secured thereto. 'I'he clip is designed to support a flash-light L of common manufacture in a position over the dial D of the telephone. For the purpose oi focusing the light relative to the dial, the arm 2 extends outwardly from and at an angle to the clamp 1 and has its upper part 4 arranged to extend at right angles to the clip 3 so that the dash-light will be held by the clip against said part 4 and thus be ilrmly held in position.
A magnifying glass 5 has a handle 6 that is formed with a rounded head 7, the opposite sides of which are attened as indicated at 8. A socket 9 oi' approximately cup-shape is attached in any suitable manner, such as for instance by spot welding, to the clip 3 at the opposite end of the latter. 'I'he socket is formed oi' spring material and has upper and lower curved jaws 10 to conform to the rounded head 7 and has opposed side jaws 11 which are flattened to engage the flat sides 8 of the head 7. The head is capable of easy insertion in and removal from the socket 9 and by 55 virtue of the rounded head and rounded jaws.
the handle 6 can be vertically adjusted to i'ocus the glass relative to the dial, while lateral movement thereof is prevented by the at sides 8 of the handle and the flat jaws 11.
From the foregoing it will be seen that the W attachment is compact and occupies a minimum of space and at the same time does not detract from the appearance of the telephone, nor interiere with free operation thereof. The device moreover is of simple and economical construce5 tion, and is devoid of parts susceptible of easy derangement under normal conditions of use.
To remove and apply the glass, a mere thrust to apply, and a like mere separating movement v to remove is all that is required to effect spreading of the jaws of the clip.` In addition, the head oi the glass handle can be applied to the clip in either horizontal position of the glass faces.
What is claimed is:
i. n magnifying glass attachment for dial telephones, including a support, means to mount the support adjacent to the dial, a member having a pair of spaced opposed spring jaws having vertically disposed fiat faces and having a second pair of opposed rounded jaws in the space between the first named jaws, and a support for a magnifying glass having flat side faces for engagement with the at faces of the rst named jaws and having rounded parts for engagement with the rounded jaws.
2. A magnifying glass attachment for dial telephones, including a support, means to mount the support adjacent to the dial, a support for a magnifying glass having a head. and a spring clip having a socket to receive the head, the head and socket being formed to allow vertical movement of the glass support relative to and about the clip and to prevent lateral movement of the glass support.
