UNITED STATES EDWARD F. KELLEY, OF 'BRIDGEPORT, \CONNECTICUT, ASSIGNOR TO THE RAYBE STOS PATENT OFFICE.v
COMPANY, OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF CONNECTICUT.
DETACHABLE EAR FOR TRANSMISSION BANDS.
Application filed. August 28, 1924. Serial No. 734,657."
' To all whom it may concern:
' respectively, located closely adjacent each other and enclosed in a casing including a cover comprising substantially the entire upper half of the casing, and which cover has a small opening in the top thereof over these drums which is closed by a hand plate. Each drum is substantially encircled by a flexible steel band lined with asbestos or other suitable material, and is provided at its ends with forked ears engaged by the operating rod connected to the familiar operating pedal for clamping the band about its drum. It is obvious that after the mechanism has been in use for some time the asbestos or other lining for the bands wear out and must be renewed. Owing to the peculiar construction of the transmission and transmission cover, in order to replace any of the linings it is necessary to remove and replace the entire transmission cover, an operation which requires considerable skill and time.
In order to overcome these objections I have constructed a band for this type of transmission having a detachable ear which may be removed through the hand opening and allow removal of the hand without the necessity of removing the cover of the transmission casing. I have also devised an improved means for securing the ear to the band'which may be easily released to allow removal of the ear, but which will securely lock the ear to the band and prevent accidental release thereof in operation. This securing means is also so arranged that the ear may be removed from and applied to the band by a simple movement radially of the hand without the necessity of any sliding movement upon the band, as the space available in the casing is very limited.
WVith the foregoing and other objects in view I have devised the construction illustrated in the accompanying drawing forming a part of this specification, similar reference characters being used throughout the various figures to .indicate corresponding elements. In this drawing ,Fig. 1 is a side view of the upper portion of a band, showing my improved securing means for a detachable ear, one ear being shown in. elevation and the other in longitudinal section.
Fig. 2 is a plan View of the ear and the attaching means therefor.
Fig. 3 is a transverse section substantially on line 33 of Fig. 1 showing the catch in secgliring position and on an enlarged scale, an I Fig. {1 is a similar view showing the catch released.
The band comprises the usual strip of flexible steel 10 to which the asbestos orother suitable lining .11 to engage the rotating drum is secured' The forked ears are indicated at 12'and 13, the recess ll being arranged to receive the operating rod. The operating mechanism is not shown as its construction is well known and 1 forms no part of my invention. The ear has a curved body portion 15 to substantially correspond with the curvature of the band.
I The means'for detachably securing the ear to the band includes a pair of spaced outwardly extending lugs 16. These lugs may be formed in various ways but are preferably formed by cutting the band with a substantially U-shaped cut as indicated by dotted lines 17 Fig. 2, and bendingoutwardly the metal enclosed by this cut at the uncut side, so that the lugs are integral withthe band. The curved body of the ear is provided with a pair of spaced elongated openings 18 to receive these lugs, and a catch 19 is pivoted to the ear at 20 between these openings. The catch isfprovided at its opposite ends with extensions 21 extending laterally in op posite directions, and which are adapted to project into transverse openings 22 in the lugs 16 to secure the ear to the band. In order to prevent accidental release of this catch, the ends 21 are bent outwardly slightly as shown in Figs. 3 and 4, and the catch itself is made of resilient material with its free ends spaced outwardly a short distance from the body of the ear. After the ear has been placed on the band with the lugs 16 extending through the openings 18 the free ings 22. The free; ends then tend to move outwardly under the spring action of the catch and the outward'lybent portions will engage the side of the openings and prevent accidental release of the catch-'inoperation. It Willbe apparent however, that the catch may beswun'g to thereleased position as shown in dottedline's'Fig; "2, and that then the earmay be removed from the hand by merely lifting it "radially away froin the band.
It'will be ap arent that this constructi'on is vei 'y' siinple and it may be manufactured at relatively.low'cost,ln t that the ear is rigidly atta'chedto the'band b'y a structure which will lock it thereto so't'hat 'there is practically no dangero'f its working' l'oose in operation. It may, 'liow'ever, be very easily and .quicklyreinoved and applied in the small space available in the transmission casing. After the ear has been removed the band may be removed from the casing through the hand opening in its top.
Having thus set forth the nature of my invention what I claim is: p
"1. Ina transmission 'or brake band, a strip of flexible material; provided a with a l ug tending voinwardly therefrom having a transverse openingtherei'n, an ear having an o eningto receive said legend a securing means movably" mounted "on the ear and provided with a portion to extend into said transverse opening to securethe ear 'to'the band. I
2. A transmission for hrakeband compris: inga curv'ed strip "of metal havin'gan outwardly extending lug'struck therefrom provided with a transverse o ening, an ear having an 'opening to receive said lug, and a catch-fipi'voted'to the earhavi ng a portion to extend into'said transverse opening to secure the ear to the band.
3. A transmissionor brake band comprising a curved strip of metal provided with-a lu'g extendin outwardly therefrom having a'transver'se openingyand a catch :movably' mounted on the ear and having aportion to extend into the' transverse opening to, secure the ear to the band, sai'd'catchbeing resilient and having a laterally extending -ipertion engaging a side oft-he opening to prevent accidental release of the catch.
4:. A transmission or brake band comprisinga curved strip of metal provided with a to secure the ear to the band, said catch be- I ing resilient with its free end tending to move outwardly'and said lateral portion being provided with an outwa'rdly'extending portion to engage the'lug under the spring action of the catch.
5. A transmission or brake band comprising a curved stri 'of metal having apai-ro'f spaced outwardly extending lugs having transverse openin s, an ear having fop'enings to "receive said lugs, anda catch pivoted to the ear between said openings and provided with lateral extensions at the opposite ends thereof to extend into the openings in the lugs.
6. A transmission or brake band comprising a 'curved'stri'p of metal having a pair of spaced outwardly extending li'ig's having transverse openings, an ear havingop'enings to receive said lugs, and a catchypivoted to the ear between said openings and; provided with lateral extensions at the opposite ends thereof to extend into the openings in the lugs, said lateral extension's'bei n'g bent outwardly at their free ends and the catch being resilient and tending to move its free ends outwar 1y.
7. A transmission or brake band comprising a curved stripoi? metal having a pair of spaced lugs cut therefrom and bent outwardly'abcut one edge,said lugs bei'ngip'rovi d'ed with transverse openings, an ear provided with spaced openings to receivesaid lugs, a resilient catch pivoted at substantially its center to the ear between said openings, the opposite ends of the catch extending laterally and outwardly, said ends being adapted to enter the openings in'the lugs to secure the ear to the band, and said outwardly extending ends coacting with the lugs under the spring action of the catch to prevent accidental release of said catch.
