1,543,522 E. R. Ross l y DETACHABLE EAR FOR TRANSMISSION BANDS Fued'sept. 4.' 1924 UNiTED STATES PATENT ELMER R. ROSS, 0F RIDGEPORT, CONNEC PANY, OF BRIDGEPO DETACH Application filed September To all whom it may concern:

Be it known that I,v citizen of the United Bridgeport, county of Connecticut, Detachable Ear ELI/imi R. Ross, a States, residing at Fairfield, `State of have invented a new and useful for Transmission Bands, of

which the following is a specification.

Mv invention relates to transmission and brake bands for automobiles and especially to a removable ear for the transmission bands of the Ford type of transmission.

It is well known that the Ford type of transmission comprises three rotating drums,

one for the low speed, and one for the brake jacent each other including a cover the whole upper half one for the reverse located closely adand enclosed in a casing comprising substantially of the casing, .and

which cover 'has a small opening in its top over these drums closed by a hand plate.

Each drum is substantially encircled by a flexible steel band lined with asbestos or other suitable material, at their ends These ears are and are provided with ears secured thereto. forked to receive the operating rods which are connected to the familiar operating pedals forl clamping the bands about the drums as is well known. It is obvious thaty after the mechanism has been used for some time the fibre linings for the bands wear out and must be renewed. yOwing to the peculiar construction of the transmission and the transmission cover, in order to replace any sary to remove of the linings it is necesand replace the entire transmission cover, an operation which requires considerable time andfurthermore after removing the cover it is replace it.

difiicult to properly In order to overcome these objections, bands have been constructed with removable ears so that after detaching oneiof the ears from the band it may be withdrawn,

and then returned to relined its position in the transmission through the handv hole in the cover without removing It is an object of my present to provide an improved band having a the cover.

With the foregoing and other objects in viewjI have devised the construction-,illustrated in the accompanying drawing forming a part of this'speciication, similar Areference characters Vbeing employed throughout the various figures to indicate corresponding elements,

Fig. 1 is a side elevation of oneend of the band and a section end, showing my improved -means for detachably securing the ear tothe band.

In the drawings I have not illustrated the three drums or the enclosing casing as their construction and arrangement is well known. I have, therefore, illustrated merely theend of a band and a removable ear and securing means constructed according to my invention. The flexible and resilient metal band is indicated at 10 lined with the usual asbestos or other suitable lining 11, whichv embraces they proper drum. Secured to the. free ends of the band are'the ears 12 andi13, either'one or both of which may be removably secured tothe band, vand these ears are provided kwith the yusual fork. 14C in which the operating rod rests.v Secured to the band and extending radiallyr thereof are one or more `studs.15. In the drawing I have shown twoalthoughone may be used or more as desired, and the curved portion 16 of the earis provided with suitable open-r ings 17 tov receive these studs. This portion of the ear is rcurvedV substantially the same asthe curvature of the band and is provided with strengthening ribs 18- to strengthen the connection vbetween this portion and the fork.

' The curved portion 16 with an elongated opening tween the studs 15 and the forked portion of the ear. Secured to the band and pivoted so that it may be turned to dierent posiis also providedr 19 preferably be-k through the other i these slits being Y the body of the tions is an oblong shaped button 20. This button is of such a size as to pass through the elongated opening when turned to a position longitudinally of the ear, but is of a length greater than the Width of the opening so that When turned to a position transversely of the. opening, as shown in Figs. 2 and 4c, it cannot pass through the opening but its opposite ends Will overlie the body portion of the ear on opposite sides of the opening. I prefer to mount this button substantially as shown, which mounting comprises a pivot stud 21v riveted to the band as shown at 22, there being a shoulder 23 to engage the upper surface of the band. The body portion of the stud extends through the opening 19 and has a reduced portion 24 at the top thereof extending through the button and forming a pivot therefor. The upper end of this portion is enlarged as shown at 25 to retain the button on the stud. Improved means is provided for retaining this button in the transverse or holding position so that it Will not Work loose in operation, but still may be easily and quickly released or applied inremoving or attaching the ear. The band l0 is slit on opposite sides of the pivot 2l as shown at 26, of suliicient length to 'allow lthe intermediate portion 27 of the band on Which the pivot stud is mounted to have a certain amount of movement relative to band and in a direction This portion is forced inainount so that it tends to pull the bottom toward the body portion of the ear. On oppositeA sides of the elongated opening the ear is provided with ribs 28 tapered in oppositev directionsand With a recess 29 in substantially the centers thereof and opposite the center of the elongated opening. The height of these ribs and recesses are such that, whenv after the button has' been inserted through the elongated opening itis turned to the transverse position, its opposite ends will ride up the inclined surfaces 30 against thespring action of the resilient portion 27 until they` reach the recesses 29, and then the resilient portion l27' Will seat them tightly in these recesses as indicated. This resilient portion as Will be obvious coacts with these recesses to prevent the button accidentally turning to the releasing position in operation. It may, however, be turned against the action of the spring bya suitable tool, as a pair of pliers, to release the button, and then the year may be'lifted of the bandV by an out- Ward movement radially thereof.

is securing means is a very simple one but will positively lock the ear to the band. The ear may be applied and removed by mere radial movement with relation to the band, and there is no sliding movement about the band required. This makes it radially thereof. wardly a certain easy to remove and apply in thelimited space available in the transmission casing.
