WILLIAM W. DEAN, OF ELYRIA, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE GABFORD MANUFACTURING COMPANY, OF ELYRIA, OHIO, A CORPORATION OF OHIO.

TELEPHONY.

Application filed August 6, 1909.

To all whom it may concern Be it known that I, WILLIAM W. DEAN, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Telephony; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

I My invention relates more particularly to telephone casingsiand especially to telephone desk sets and the details thereof.

Some of the objects of my invention are to provide a desk set, all of the parts of which are rigidly connected to one another, thus avoiding the use of unnecessary pivot connections between the various frame parts; to provide a convenient arrangement for associating the switch hook and the contacts controlled thereby with the casing in such a way that they are accessible to the workmen; to provide connections between the various parts of the casing in such a way that they do not interfere with the cleaning of the exterior of the casing,'and

. at the same time those-which are operable may be accessible from the exterior of the casing. I have endeavored to produce such a desk set by connecting the various casing parts and to reduce the number of these parts to as few as possible, making a cheap, compact and easily constructed set.

In desk stands now in use, the transmitter and mouthpiece are pivoted to the standard. In eliminating this I construct my desk stand so that the front of the transmitter is inclined at an acute angle to the vertical; that is, a line drawn through the face of the front to intersect a line drawn through the axis of the standard, intersects the same, making the angle nearest the instrument less than a right angle. I have so inclined this front for the purpose of making the mouthpiece convenient to one who seated at a desk, uses the telephone. Of course the inclination of the front may be changed to suit different conditions and for different positions of use. For the general use to which desk sets are placed they are either set on a desk and talked to or held in the hand. In the former case, the stand setting on the desk presents the mouthpiece below, the mouth of the user; in the latter, the user Specification of Letters Patent.

holds the stand so as to receive some support therefor from the chair or his body in In the drawing, Figure 1 is a cross-section.

through the desk set showing the arrangement for supporting the telephone apparatus therein and the connection between the various parts of the casing. Figs. 2, 3, 4:, 5, and 6 are details of the casing showing the means for connecting the detachable parts to the casing proper.

l is the hollow base to which the vertical standard portion 2 is attached. In the drawing these parts are shown as drawnfrom the same piece of metal.

3 is an enlarged hollow casing adapted to house part of the telephone apparatus attached to the upper part of the tubular casing. The parts as shown in the drawing are united so as to form a single compartment for the apparatus, each part communicating with the others, either directly or through the hollow standard. By eliminating partitions I lighten the set and facilitate the running and making of the circuit connections. In the form shown inthe drawing the standard 2 is extended into a narrow finger piece 17, and the enlarged casing 3 attached thereto by the screws or rivets 18 which make a rigid connection between these parts. A hollow portion projects frointhe hollow casing and, in the form shown, telescopes with the standard, being rigidly connected therewith, The front of the enlarged. casing is inclined at an angle to the standard 2, and a front piece 4 carrying the mouthpiece 5 is adapted to be detachably connected theretoto close the front of this casing. An inverted cup 6 is fastened in the base of the set. A cover 7is adapted to be detachably connected to close the mouth of the cup 6. An annular angular ring 14 is shown bent over the edge of the cup. An annular rubber ring 8 is inclosed between the lower desk set.

edge of the base and the set and this angular ring, furnishing a resilient bufier for the p The bottom 7 ofthe cup is fastened thereto by a hook 35 which fits over the angular ring as shown in the drawing,

and a rotatable catch member 13 which engages the annular ring 14 as a counterpart or cotiperating catch member when the memof the catch 13 to engaging position with the counterpart catch member on one side and to complete disengaging position with the said catch member on the other side.

"A screwdriver or similar tool may be in- .3 L'ing, are arranged to hook over each other casing.

casing portion is connected thereto by a "joint and catch arrangement very similar to that just described. A catchhook 46 and serted through the recess 12 into the slot 11 to rotate the member 13 in order to lock or 25 release the bottom to or from the cup. The

terminals 15 are'mounted in the base of the casing and the conductors 16 extended through the standard portion to the contacts which are included in the enlarged hollow The front of the enlarged upper a counterpart catch member 45, the former attached to the front, the latter to the easwhen the front is placed upon the casing.

At 19 I show a catch housing attached by rivets 32 to the enlarged upper casing portion. A hook catch member 21 is inclosed within this casing to rotate between abutments 38 and 39 formed on the casing 19 and which limit the rotation of the hook. "hook catch 21 is bent upward at and extendedinto a hook 30. A slot 22 is cut in The the base of the hook catch and coeperates with the recess 20 in the casing 3. The hook engages with acounterpart catch member 31 I formed on the front piece. In the drawing this piece is shown in the form of a tongue out from the front itself and bent upward. Aftool maybe inserted through the recess 20 into the slot 21 and the hook rotated between the limits ofthe abutments which confine the movement-from full engagement position between the catch members and position of complete disengagement.

It will beseen that I thus provide means for conne'cting these detachable parts which are located entirely within the casing and which may be operated to quickly and easily unlock the catches by means inserted from 7 without the casing.

The transmitter bridge bearing a trans- ]mitter and attached to the casing front is.

I bracket.

shown at 23. I show a bracket 40 attached at 24 to the standard portion and extending upward into the enlarged part of the casing. The switch hook 43 is pivoted at 42 to said The contacts 25 and 41 and a hook controlling spring 44 are also carried by this bracket. The switch hook 43 controls the connection and disconnection of the springs 25 and 41. The contact springs and the switch hook arrangement and other apparatus carried by the bracket, can be easily reached by removing the front 4.

I thus provide a desk set which is simple, and compact. The telephone apparatus is inclosed in the two extremes of the set and the portions in each extreme may be readily reached by removing the detachable portions at the top and bottom of the casing. These detachable portions are not attached by any complicated locking mechanism, and yet this locking mechanism is of such nature that it cannot be operated without the use of some tool. It is simple of construction and easy to operate, so that the apparatus inclosed within the casing can be quickly and easily approached.

While I have shown and described this particular form of my invention which is my preferred form, it will be obvious to those skilled in the art that numerous and extensive departures from the'form and details of the apparatus thus shown, may be made without departing from the spirit of this invention, the same being herein shown solely for the purpose of clearly illustrating one specific embodiment thereof.
