' a. citizen. of the United States, residing at end view {)Il' the paper feed roll.

, desk l-xn Francisco, in the county of San Fran euro and State of Cali'fminia, have invent ed a new and useful Sanitary Guard for Telephones, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the This invention relates to a sanitary device for telephone mouth pieces. Its ohject is to provide means whereby the mouthpiece ot' the telephone will he kept from accumulating disease germs from the sputum of telephone users.

Another oh yeet of the invention is to provide means whereby the protective covering of the mouthpiece will be ,automatically sh'i'l a when the telephone user picks up the telephone.

Other objects wil appear as the descrip tion proceeds.

resents the sending apparatus of the telephone on which is secured this attachment.

The numeral 5 represents a plate which is secured to the telephone sending apparatus by screwing the mouthpiece intothe usual position through said plate. The plate 5 is provided with forwardly projectlug flanges 6 at each side thereof, which flanges support the paper roll and thcapparatus for shifting the paper used to'prevent soiling the mouthpiece. Projecting forwardly from the top and bottom of the plate 5 are two skeleton frames 7 and 8, each of which serves toguide and hold the paper in the .proper position in front of the mouthpiece. The upper guide 7 is pro vided with upwardly projecting ears 9 roll 10. At the upper end of each of the set of flanges (3 there is an opening in which a rod 11 is inserted, said rod carrying a spring 15 which bears upon a presser plate 13, said presser plate bearing in turn upon the paper roll to regulate the tension of the paper as it is pulled across the mouthpiece. This presser plate has two backwardly extending ears through each of which passes the rod carrying the spring; 15.

Atthe lower portion of the flanges 6 there is a paper teed roll 16. This paper feed roll is loosely journaled upon a shaft 17 said shalt having a ratchet wheel 18 atoms end and a small pinion 1.9 at the other end. The paper feeding roll has a pawl 20 which bears upon the ratchet pinion, a spring 21 holding said pawl in engagement with said ratchet pinion, thus preventingthe paper feeding roll from moving in one direction. Above the paper feeding roll there is a shaft 22 having a pinion 23 thereon, said pinion 23 being in mesh with the small pinion on the shaft of the paper feed roll. The large pinion is provided with a pin 23* which projects through a. slotin an operatcars 30 through each of which the said shaft the used strip of paper.

The standard of the telephone has at-tube 33 surrounding the same said tube'being made in two parts for the purpose of readily placing the same upon the telephone standard, and it is. provided with a slot 34 to prevent the same from twisting around the standard, said slot movingalong the receiver arm when the standard is picked up. .axtending from the top of the sleeve is a link 35 which link connects with the rearwardly extending arm of the operatin shaft and enables the paper feed roll to be moved'such an amount as may be necessary each time the telephone is lifted up.

Where it is desired to use a wall telephone instead of a portable telephone the operating shaft is turned downwardly so that it is in convenient reach of the telephone user as shown at 36, thus enabling the paper to be fed across the mouthpiece should the telephone be one of the so called "Wall.telephones or should it be desired to operate without the automatic feature.

The operation of the device is as follows The paper supply roll is placed upon the upwardly projecting ears at the top of the device, the presscr plate bearing thereon. The paper is then pulled across the mouthpiece, over the guides and is inserted between the-roller and the presser plate hearing thereon. The device isthus ready for use and each time the telephone is picked up the sleeve thereon will lift the operating -arm and cause a certain amount of paper to be pulled across the mouthpiece, thus presenting a fresh piece of paper for the telephone user.

Having thus described my invention what I claim as new and desireto secure by Letters Patent of the United States, is as follows 1. A sanitary deviize for telephones comprising a frame adapted to be secured to the sending apparatus of a telephone, a paper roll, means to supportsaid paper roll on said frame, guides to hold said paper in front of the, mouthpiece of a telephone, a paper feed roll jonrnafled in said frame, and means to cause said feed roll to pull a predetermined quantity of paper across said plephonemouthpiece when the" telephone is lifted up, substantially as described.
