SAMUEL J. BALLARD, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF THREE- FOURTHS TO CALVIN W. BROWN, OF LOS ANGELES, CALIFORNIA.

GUARD FOR SPEECH RECEIVERS OR TRANSMITTERS.

SPECIFICATION forming part of Letters Patent No. 719,987, dated February 10, 1903.

Application filed July 2, 1901. Serial No. 66.921. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL J UDSON BAL- LARD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles. and State of California, have invented a new and useful Guard for Speech Receivers or Transmitters, of which the follow ing is a specification.

This invention comprises a holder for holding a plurality of protecting-sheets in proximity to the mouthpiece or earpiece of the sound transmitter or receiver. It includes the appliance and parts herein described and claimed. Preferably the sheets are perforated and pivoted on a pin and retained thereon by a suitable retainer, and means are provided for pressing the leaves toward the retainer, said leaves being adapted to be moved one at a time in front of the mouthpiece or earpiece.

This invention is designed to provide a clean removable covering for telephonemouth and ear pieces which can be changed at will by pulling ofi one slip or sheet and turning into place over the aperture of the instruwent a clean slip or sheet which has not theretofore been breathed upon or touched by a user of the instrument.

It is a well-known contention with physicians that contagion can be spread through the promiscuous use of the telephone by diseased people, besides which it is not pleasant to use a public telephone which may have just before been used and breathed,

smoked, or even coughed into or which may have been held against the perspiring ear by some person of doubtful cleanliness. For reasons conducive to good health alone many would not consent to hold hands with an unknown person for the length of time of an Another object is to provide a useful device by means of which advertisements may be made acceptable to be placed and kept in constant view where they would not otherwise 5 5 be admitted.

Another object is to provide a convenient tablet on the mouthpiece on which may be written memoranda, such as telephone-numbers or names of parties desiring to be called up by some particular person. This memoranda can be removed by tearing off the marked sheet without disturbing the one in place over the aperture of the instrument,and the marked sheetmay be carried away for reference, thus further disseminating the advertisement.

Another object is to provide a sanitary guard for telephones, earpieces, and mouthpieces which may be easily replenished by any ordinary printer.

Another object is to combine in such sanitary guard a businesscard of the telephone owner giving his telephone-number, so that the user of the telephone will have in view the number of the telephone to which the device is applied. Such information being on a convenient card or slip which can be easily detached and carried away for reference also adds to the value as an advertising medium.

A-further object of supplying a memorandum-space to be used by the user of the telephone is to prevent the mutilation or marking of walls by the making of memoranda on the walls.

The accompanying drawings illustrate my invention.

Figure I a perspective view of the invention with the protecting leaves, slips, or sheets and in use as an attachment to a tele- 9o phone-transmitter. Fig. II shows the device in use on a telephone-receiver. Fig. III is a perspective view of the device ready for attachment to a transmitter or receiver. Fig. IV is a view of a sheet-metal blank adapted 5 to be used in the manufacture of the holder. Fig. V is a side view showing the holder ready to receive the protecting sheets or slips. The sheet-retainer is shown detached. A cross-section of the pin is also shown. Fig. I00 V1 is a front view of one of the protecting slips or sheets. Figs. VII and VIII are front views, respectively, on a reduced scale, of a frame formed in one piece and a blank for forming such frame. Fig. IX is atransverse sectional view, on an enlargedscale, of the pin portion of Fig. VII.

1 indicates a plurality of protecting slips or sheets of paper or any other suitable material. Paper of any desired thickness may be used, as I have found by experiment that two sheets of thick blottingpaper will not preventthe ready transmission and reception of sound through the telephone. 2 indicates in a general way a holder for said sheets adapted and arranged to hold said sheets or slips in position for being respectively and successively moved into position in front of the instrument to which it is adjusted.

In practice the outside slip or sheet a or the one next thereto can be turned into position across the mouth of the instrument, as indicated in Figs. I andII.

3 indicates the transmitting or receiving appliance, to which the holder will be attached by a clamp 4. The holder comprises a standard 5, connected with the clamp 4, and a leaf-supporter, as a guide 6, fastened to the standard to guide the edges of the leaves or slips.

7 indicates a post or pin extending alongside the guide at a distance therefrom to pass through perforations 8 in the protecting slips or sheets. The pin 7 is fastened to the support 5 and is furnished with two opposite notches 9.

10 indicates a sheet or slip retainer to re tain the slips or sheets in place on the pin 7. This retainer is preferably made of a thin strip of metal perforated with a hole 11 to pass over the pin 7 freely and furnished with a slot 12 to embrace the neck formed between the notches 9 in the pin. Resilient means are provided for pressing the leaves 1 toward the retainer 10.

13 indicates a spring for this purpose. The

free end of the spring is preferably expanded,

as shown, and acts as a back or support to bear the pressure upon the leaves when they are being written upon.

The clamp 4, standard 5, and guide 6 are preferably all formed of a single piece of bent sheet metal. 14 in a general way indicates a blank from which said parts Will be pressed into shape.

15indicatesa clamp bolt and nut for clamping the frame on the earpiece or mouthpiece.

In practical use the appliance will be fastened to the telephone or other mouthpiece or earpiece, and a bunch of slips perforated with a hole 8 will be placed on the guides 6 and over the pin 7 and will be secured by a suitable retainer, such as that shown at 10, the spring 13 being compressed to admit of the insertion of the sheets between the standard 5 and the retainer 10. The pressure of the spring 13 constantly holds the sheets forward in position against the retainer, and the user whenever he desires may turn a sheet to bring it past the ends of the guide 6, which for this purpose terminate rearward of the notchformed seat 9 in the pin. When the sheet is turned into position across the opening of the receiver ortransmitter, the appliance is ready for use. It is to be understood that the slips a may be wholly or partially given over to advertising or advertisements may be emitted, at the pleasure of the user, without departing from the broad spirit of my invention. When the user desires to provide a new surface, he will tear off the old slip and turn a new slip into place.

The retainer 10 is preferably expanded and extends in two directions from the hole which receives the pin 7, and one arm of it serves to hold the sheet or slip against the mouthpiece or earpiece, as the case may be, and the other arm holds the sheets or slips against the pressure of the spring 13.

16 indicates a cross-bar formed of the sheet from which the members 4 4 5 and 6 6 are bent.

17 18 indicate holes in the standard 5 for fastening the pin 7 and spring 13, respectively, to said standard.

Figs. I to IV show the pin riveted in the hole 17 and the spring 13 inserted in hole 18 and soldered fast.

In bending the frame comprising the crossbar 16, clamp members 4, standard 5, and guide members 6 the clamp members 4 will first be bent forward at the dotted lines or and then at the dotted lines y. The members 6 will be bent forward at the dotted lines z, thus leaving the bar 16 and the standard 5 at one edge of the bar in one common plane, the guide-arms 6 projecting forward lengthwise from the bar at the edge thereof from which the standard projects and the clamp-arms 4 projecting edgewise from the bar opposite the guide-arms.

In the form shown in Figs. VII and VIII the tongue 51, which is provided with notches 91 to form the retainer-seat, will be bent at the cuts 10 and will then be bent downward into tubular form to form the pin 71. (Shown in Fig. VII.) The tube thus formed may be fastened at w by solder. In this form the standard corresponding to the standard 5 in Fig. IV is formed in two members 53, respectively, on the opposite sides of the member 71, which forms the pin.

The designating-number of the telephone to which the device is applied may be stamped on or otherwise applied to the face of the retainer, thus to inform the user of the telephone as to the number thereof.
