Application filed April 23, 1900. Serial No. 13.867.
To (LZZ whom, it may concern:
Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Adjusting Devices, of which the following is a specification.
This invention relates to adjusting devices, and has for one of its objects the provision of means for adjusting a stud or similar mem ber to a precise working position, in which it may be held or locked against displacement.
My invention includes as one of its elements a rotative member or actuator for imparting movement to and also for holding a rotatable member, while in the present organization the rotatable member is adapted to have a longitudinal shifting movement in addition to a rotary movement.
Another feature of my invention relates to the el'nployment, in connection with the rotative member, of means for checking the movement of and locking the various members in an adjusted position, the several organized and coacting elements-na1nely, the rotatable member, the rotative member, and the checking and locking means-forming a self-locking adjusting device especially adapted for use in connection with cam-roll studs and similar machine elements which require longitudinal adjustment to a precise working position.
The present invention also embodies a construction for cam-rolls and a relation of the latter to each other and to their actuating cam-surfaces especially designed to form a satisfactory working combination in which looseness resulting from wear or from other causes may be taken up by a simple adjusting movement.
The invention in its preferred construc tion is illustrated in the accompanying drawings, in which Figure 1 shows my invention applied to a cam-actuated carrier. Fig. 2 is a central section of the cam and of rolls actuated thereby. Fig. 3 is a sectional detail and illustrates on an enlarged scale the roll-carrying end. of the carrier. Fig. 4 is a section on line 4 4, Fig. 3. Fig. 5 is an end view of the roll-stud; and Figs. 6 to 8, inclusive, are details of several parts which serve to retain the rolls in place on the stud.
Similar characters designate like parts in the different figures of the drawings.
As before stated, the primary object of my invention is the provision of a device whereby a cam-roll stud or other analogous member may be adjusted to a precise working position, and one way in which this may be done is clearly illustrated in the drawings, in which a shaft 10 is represented having mounted thereon a cam 1 1, provided with a groove 12, the walls of which present a pair of coacting cam-faces 12 1.2 in engagement with rolls 13 and 14, respectively. These rolls 13 and 14 are slightly tapered to correspond to the faces 12 12, which are similarly formed. It will be seen, therefore, that when a stud 15, upon which said rolls may be journaled, is moved with the same toward the cam, as seen in Fig. 2, the roll-surfaces are brought into closer contact with their respective ac tuating cam-faces, and vice versa. This disposition of the working faces of the cam members and cam-rolls at an angle to the line of adjustment of the supporting-stud, as seen in Fig. 2, is particularly advantageous, since a slight axial movement of the stud, and with it the supported rolls, serves to take up any wear or looseness arising from other causes and to make the parts fit snugly in contact with each other. The shifting of the roll-stud longitudinally may be accomplished in the manner shown in Figs. 3 and 4:, in which the longitudinally-shiftable member or stud 15 is provided with screw-threads 15, in engagement with similar threads in the head of a carrier C, so that the rotation of said stud will produce a longitudinal shifting movement of the stud.
Preferably the stud is provided with a series of shoulders which may be disposed obliquely to the screw-threads above mentioned and are shown herein as in the nature of teeth engaged by coacting shoulders, illustrated as being threads of rotative screws 1.7 and 18, either of which may serve as an actuator for turning the stud, while the other serves as a check for the former. Both rotative members are actuating-screws, being disposed oppositely to adapt them for turning said studs readily in opposite directions. Both of the screws 17 and 18 are seated in this case in the head portion of the carrier C and may have their inner ends tapered, as at 17 and 18, to adapt them to enter conical recesses 20 and 21 in the head, this construc- 1 structed with a friction member for frictional tion providing an efficient means for frictionally preventing accidental rotation of the screws after they have been properly seated, and thus locking the parts.
In the illustrated construction the shoulders with which the actu ator-screws 17' and 18 cooperate are disposed between the screw threads 15 15, and hence the portion of the stud with which such actuators engage is located between bearing portions which serve to steady the stud in the carrier or member C. The relation between either one of the actuator-screws and the shoulders upon the stud with which it engages is similar to that existing between a worm and a worm-wheel, and, infact, the means for turning the stud consists of a worm-wheel in operative relation with a pair of worms.
The rolls 13 and 14- are, as above stated, journaled on the stud 15 and may be held in place thereon by a collar or washer, such as 22, secured to the stud 15 in a manner clearly illustrated in Figs. 5 to 8, inclusive.
-The stud 15 has at its forward end a flange 23, between which and the main body portion of the stud may be placed a pair of halfrings 24, the original shape or form of which is shown in section in Fig. 8. The collar 22 is then slipped over the half-rings, as shown in Fig. 4, whereby the latter are prevented from falling off, and the outer edges 24 are then headed over to keep the collar in place.
The present invention affords a simple method for effectively and securely holding a rollstud in a position to which it may have been moved in effecting an adjustment of a supported roll or rolls as well as a construction and a relation of coacting cam and camroll surfaces in which a simple movement accomplishes the adjustment and intimate contacting of the parts.
