BRAKE-BAND moon. f

Application filed January 2a, 1926. Serial m. 83,102. a

This invention relates to means for facilitating the renewal of the transmission bands in the Ford type of motor vehicle, the general object of the invention being to pros videmeans for drawing a band around its This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafterf-ully described, il-

v lustrated in the accompanying drawings and specifically pointed out in the appended claims. 1

In describing my invention in detail, reference will be had to the accompanying,

drawings wherein like characters denote like or corresponding parts throughout the s eve v eralviews, and in which Fig. 1 is a sectional view through a trans,

2'0 mission means showing a spring member "being used to place a band on its drum.

Fig. 2 is a similar view showing another step in the operation.

Fig. 3'is a View of the spring member. Fig. 4; is a partial view of the band. 7 "Fig. 5 is a view of thedetachable ear therefor. j l

As is well known, the Ford type of motor includes in its transmission the drums 1 and the bands 2, each band having a detachable ear 8 which has key-hole shaped slots 4: therein for engaging the headed studs 5 on the band and a round hole 6 for receiving a rivet 7 .on the band; This end of each band is also provided with a hole 8.

lVhen a band is to be removed, this ear is removed and then the other car seized and the band pulled from around the drum. In replacing theband or a new one, the end serted between the transmission casing and the drum, after the upper part ofthe case has been removed, and a tool must be used to fish for the band if the band .fails'to'be thereof which carries the detachable ear'is inguided by the flanges of the drum as it is 10 which is adapted to eng f headed studs5 oftheband. The other end of the, strip B is bent upon itself, as shown at11.

When a band is to be removed and then the ear-is'removed from the band by a suitable tool. The band is then seized by its other ear and pulled fromaround the drum. The tab 9 of the member B is then connected with the new band or the old one if this is to be replaced, by placing the slot 10 over one of the headed studs 5 of the band. The end 11 of the spring strip B is then placed on the drum andthe I removed, the nut and washers are taken ofi the shaft and the shaft strip pushed upon to cause it to pass around the drum as shown in Figure l. The strip is then pulled around the drum, and as the band is attached thereto, the band will also and a part of the casing, when further move- ,mentwill be prevented. This will bring the. other end of the band at'the top of the drum.-

The tab 9 is moved to one side so as to ex-s pose theiopening 8 and then a tool is placed in said. opening. -The tab is then removed from the bandand the studs 5.

Fromthe foregoing, it Waite seenlthat I have provided simple means wherebythe' transmission bands can be easily removed from and replaced onthe drums through the inspection opening and Without removingthe upper portion of the transmission case. As will be seen from the drawings, by makthe ear 3 placed over be pulled around'the drum, as shown in ure 2. The band is pulled around the drum. untilits permanent ear engages the drum ing the band or strip B of spring metal, its.

tension will cause it to coil upon itself and thus it will follow the contour ofthedrum as it is pushed over the same so that there i is no danger of the .band being checked in its movement from any part. of the trans mission casing. V I

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent. I desire it to be understoodthat I may make changes in the construction and in the combination and arrangement of the several I v 7 parts, provided that such'changes fall within the scope of the appended claims.

Vvhat I claim is I 1. A tool for facilitating the removal of a transmission band from a transmission drum comprising a strip or band formed ot L insane, I

spring metal and means at one end of the band for detachably engaging a part of a transmission band to connect the said transmission band to the tool, the tension ot the spring strip causing it to follow the contour of the drum as the strip is pushed over the drum. i r

'2. A tool for facilitating the removal or a brake band from a transmission drum comprising a spring strip and a tabhinged to one end thereof so that it can move about an axis which is at right angles to'the length of the strip and said tab having a slot therein,the tensionof-the spring strip causing it A class described, a predetermined length of to follow the contour of the drum as the strip is pushed over the drum. 7 i

3. Ina transmission band installer of the i normally coiled flexible material adapted'for forcible engagement around a drum of the transmission, one end of said length of mate rial being adapted for detachable connection to one endof the transmission band being installed, the other end of the length of material providing a meanswvhereby the same may be moved around the drum for position- "ingthe transmission band on the drum, the

length of the material being removed from the band when the latter is in its proper position.

4. In a transmission band installer of the class j described, an elongated strip of nor- 7 mally coiled spring metal adapted reefercible engagement around the drum of the transmission, a hook at one end of said strip adapted for detachable engagement with one end of the transmission band, the other end, of the strip providing a handle portion whereby the strip may be moved around the drum for positioning the transmission band thereon, said hook beingdisengaged from the transmission bandwhen the latter is in proper position.

5. In a transmission band installer of the class described, anelongated strip of nor mally' coiled spring metal adapted for for cible engagement around the drum of the strip may be moved around the drum for po' sitioning the transmission" band thereon,

mission band When the. latter'is in proper position around the drum,

6. A tool for inserting a band around a 'transmisssion drum on an automobile, com

prising a resilient member of less curvature thanthe curvature of the drum, and pro+ vided at one end with means'adapted for vdetachable connection with one end of the 'band. l v r '7. A tool for inserting a band around a transmission drum of an automobile, comthanthe curvature of the drum, and provided at one end with a slot for detachably connecting with one end of the band.

8. A tool for inserting a band around a' '55 said hook being disengaged from the transprising a resilient member of less curvature V transmission drum of an automobile, compris ing a resilient member of less curvature than V the curvature of the drum and of substantially the Width of the band, and provided at one end with manual gripping means and at the other end With a slot for detachably connecting with one end of the band.

In testimony whereof I aiii'x my signature.

LEONARD E. WATSON.
