BENGT M. W. IIANSON AND JOHN H. MONTSTREAM, OF HARTFORD, CONNECTICUT7 ASSIGNORS TO PRATT d: WHITNEY COMPANY, OF HA RTFORI), CONNECTICUT, A CORPORATION Ol NEW JERSEY.
ADJUSTABLE CAM.
Specification of Letters Patent.
Patented oct. 1 5, 1907.
To all whom it may concern:
Be it known that We, BENGT M. W. HANsoN and JOHN H. MoNTsTREAM, citizens of Sweden and of the United States, respectively, residing at Hartford` in the county of Hartford and State of Connecticut` have invented certain new and useful Improvements in Adjustable Cams, of which the following is a specification.
This invention relates to a new and useful improvement in cams, and has for its object the production of a cam the operative face of which may be readily and quickly adapted for various throws and the positions of said face may be changed without removing the cam from place.
-In the accompanying drawings: Figure l represents a plan or full view of the device. Fig. 2 an edge View; and Fig. 3, a detail perspective View.
Like numerals designate similar parts throughout the several views.
The numeral l designates the supporting piece, in the present instance shown as a disk provided with a central hole 2 and a perforated hub 2 to receive a shaft. This disk l is Yprovided with two sets of concentric threaded holes7 3 and 4, consisting, respectively, or several holes. One set of holes 3 is located near the 'periphery of the disk l, and the other set of holes 4 near the central hole 2. There may be any desired number oi holes in each set. Secured to this support-ing piece l is the cam-faced piece 5. This piece 5 has the main part 6 and tongue 7, connected by the neck 8, the neck and tongue being curved so as to inclose the hole 2. The tongue 7 is provided with a slot `or elongated opening 8/, and the main part 6 has a cam-face t) and curved edges l0. In the slot 8/ of the piece 5 is placed a binding screw l1, threaded so as to engage any of the holes 4 and a holding screw l2 is secured at the outer edge and at one corner of the piece 5 and is adapted to be inserted in any ol' the holes` 3. The tongue 7 may be provided with a scale 13, and the disk l with a number of lines or marks 14 located over the holes 4.
The parts are secured together as shown in Fig. l, the binding screw Il passing through the slot S and engaging one of the holes 4 and the holding screw l2 engaging one of thel holes 3. This forms a cam with an edge l0 and cam-face l2 ready for operation. Should it be desired to change the throw oi the cam the binding-screw 7 is loosened, removed to another hole 4 and tightened up. It change of position is desired the holding-screw l2 is loosened and placed in another hole 3, and the binding-screw 7 adjusted to tit. With these two adjustments this one device may be varied at will to provide cams of different throws or of different positions.
Changes may be made in the form and proportions of the parts, the invention not being limited to the precise devices shown and described.
Having thus described our invention, what .We claim is:-
1. The comhiimtion. with a disk having`- sets ot' concentric holes, of a piet-e havinga slotted tongut` and a camfact: :1 hinder passing.:l through the slot ot' th(` tongue. and adapted to cuter any holt` of ono serios: and a second hinder passing' through said piece. and adapted to enter any hole ot' the other serios.
2. 'lhel combination. with a disk having a serios 'of ooncontt'ically-disposed holes at one point thereof: and a socond series ot' concentricallydisposed holes at another point thereof: ol' a cum-primer having: a curved and slotted tongue: a screw entering the cam-proper and threaded into a hole of one series: und a second screw passing through tho slotted tongue. and threaded into the holt` of the other series.
ln testimony whereof we atlix our signatures in presence of two witnesses at llartt'ord. tonn.. Fel). 14. ltlot.
