SPROCKET.
Specification of Letters Patent.
Patented Nov. 19, 1907.
Application filed July 1, 1907' Serial N0. 381.742-
. provements in S rockets, of which the -folowing is a speci cation.
Heretofore in moving picture machines and the like, sprockets and the sleeves therefor have been utilized which were stamped or otherwise formed of a single piece of metal and secured on a shaft by means of pins,
Y which had to be removed in order to remove the sprockets. Sprockets of this class are used 1n pairs, one'on each end of the sleeve, which spaces them the correct distance ap art, and in the event of one of the sprockets becoming worn or broken, it has been necessary to Ipurchase a'complete new set of sprockets an the sleeve therefor in order to renew the worn or broken sprocket.
The objectv of our invention is to provide a construction which enables the removal of one sprocket or both sprockets from the sleeveholding the same without the necessity of removing the sleeve and replacing it by another. v
.A further object is to provide aconstruction whichv will admit of the longitudinal adjustinent of the sprockets along the shaft.
A further object is to provide a simple construction so that the parts which need to be -removed from time to time on account of wear, 4may be chea ly manufactured.
We accomplish tlh the device describedherein and illustrated in the accompanying drawing, in which Figure 1.- is a plan view of my sprocket construction as applied to a moving picture machine. Fig. 2.# is a central longitudinal section of the same. Fig. 3.- is across-section taken on line 3-3 of Fig. 2.
Referring to the drawings, 5 designates `a typical shaft of the general .form used in moving picture machines for the sprockets therein, and on which shaft is mounted a sleeve 64 rigidly secured thereto by means of set screws 7 bearing in a giioove 15 inthev shaft. This means of atta ng the sleeve to the shaft provides for the longitudinal' ad- ]ustment of the sleeve so as to correctly place the sprockets in relation to the other mechese objects by means ofV bear, being held in place by screw flanges 10 in screw threaded engagement with shaft 5 as shown in Fig. 2. Flanges l() are provided` u on their outer faces with nuts 11 by means of) which they may b 'e turned up tightly against sprockets 9 so as to hold the sprockets in rigid engagement 'with flanges 8. Flanges 8 are provided with screw threaded pins 12,` which project into recesses 13 in sprockets 9, and thereby prevent any rotation of the sprockets on flanges 8. The shaft bores of sprockets 9 are further provided with lugs 16 which fit into groove 15 in the shaft and further prevent any rotation of the sleeve and sprocket thereon; f Sprockets 9 are'preferably stamped out of sheet metal and provided with teeth 14 formed integrally therewith, the sprockets being shown greatly enlarged in the drawings. These sprockets are made in this form so that they may be stamped out of the sheet and therefore can be very cheaplymanufactured.
It will be observed-that the sprockets in my'construction may be readily and quicklyV removed from the machine without the necessity of removing any other parts therefrom,v and further, that they may be'4 very easily replaced by new sprockets. It will further be noticed that my arrangement enables of a sprocket construction which 1s very cheap andv therefore, permits .the replacing of worn out sprocketsat a minimum expense.
Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a sprocket construction, a sleeve; a flange on either end of said sleeve; sprockets ,adapted to bear against said flanges; and
means to detachabIy secure said sprockets on said flanges.
2. In a sprocket construction, a shaft; flanges rigidly s aced upon and secured to said shaft; sproc iets adapted tobear against said flanges, said sprockets bemg. provided with recesses therein; lugs on saidflanges adapted to engage said recesses in said sprockets;V and nuts in screw threaded engagement with said shaft, said nuts adapted to hold said sprockets in rigid engagement with said flanges.
3. In a sprocket-construction, a shaft; a sleeve rigidly mounted on said shaft; a flange on either endvof said sleeve,` said flanges being provided with projecting pins on their A. the outer faces of said flanges, said sprockets being provided Wit-h recesses adapted to be engaged by the pins in said flanges; and nuts in screw threaded engagement with said shaft adapted'to bear against the outer faces of said sprockets and hold said sprockets in j engagement With said flanges.
et. In a sprocket construction, a shaft prof vided With a longitudinal groove therein; a sleeve mounted on said shaft and provided With set screws adapted to bear in the groove in said shaft, said sleeve being further provided With a flange on either end; projecting pins on the outer faces of said flanges; sprockets adapted to bear against the outer faces of said flanges, said sprockets being provided with recesses adaptedto be engaged b v said pins, said sprockets being further provided With lugs adapted to ent-er the longitudinal groove in said shaft; and nuts in screw threaded engagement with said shaft adapted to .bear-against the outer faces of said sprockets and hold said sprockets in engagement With said flanges.
In Witness that We cla-ini the foregoing We have hereunto subscribed our naines this 1 24th day of June,1907.
