DOUBLE-MOTGN CAM DEVICE.
Application nled August 30, 1921. Serial No. 495,935.
To all fr/wm t may concern Be it known that l, Anonrii il. lllnnnonnn, a citizen of the United Statearesiding at Norwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Double- Motion Cam Devices, oit which the 'following is a specification, reference being had therein to the accompanying drawings.
lThis invention relates to a. double motion cam device, and has for its object the construction ot a simple and etlicient device which will enable an operator to adjust the jaws slowly or quickly by the rotation ot a cam plate through the medium ot a handle, gripped by the opera-tor. j
Another object oft' the invention is the construction oit a double motion cam vise ot simple and eiiicient construction, adapted for controlling presses, milling machines, and bench assembling but can be used successfully in horizontal and vertical tapping machines, as well as turret lathes.
With these and other objects in view, my invention comprises certain novel combinations, constructions and' arrangements ot' .parts as will be hereinafter described, illustrated in the accompanying' drawings, and more particularly pointed out in the appended claims.
In thedrawings: Figure l is a vertical sectional view through the device, while Figure 2 is a top plan view ot the same, showing a part o't' the cap plate bronzen away. Figure 3 is a sectional view taken on line 3-3, Fig. l, with the drum and pin removed. Figure 4 is a plan view ot the cam plate. Referring to the drawings by numerals, 1 designates the bed plate having a central opening 2, and the bed plate is provided with bifurcations 3 at opposite sides, for receiving any suitable means tor fastening the bed plate to a carriage or support.
Resting upon the bed plate l is a cap plate 4. This cap plate is provided with an inner annular flange 5 and an outer annular iiange G. rllhe annular flange 5 extends down into the opening 2, and the annular flange G rests against the outer edge ot the bed plate 1, Figs. 1 and 2. The cap plate is fastened securely to the bed plate, against rotary movement.
The cap plate is provided with aligned elongated slots 7, and with raised ledges S between which is Yformed a groove 9. Posiledges 8.
Each aw 1l comprises an elongated body having an upwardly-extending i apertured lug 18, and depending trom the bottom ot the body: is an integral primary extension 14, terminating in a reduced extension 15. The primary depending extensions 14 ot the jaws 11 are positioned in the elongated slots 7 ot the cap plate 4, under the groove 9.
A. cam plate 16 rests upon the top ot' the bed plate l, under the cap plate 4. This cam plate 1G is provided with a large, central aperture 1'?, which allows the cam plate 1G to be rotatably mounted around the flange pwr hub o ot the cap plate 4, Figs. 1 and 3. .extending through a suitable slot, formed between the dotted lines 1S, Fig. 2, upon the side ot the cap plate 4 is a handle 19, which handle is securely rastened, at 20, Fig. 1, to the cam plate 16. Upon moving the handle 19, the cam plate 1.6 will be rotated around the flange 5 for moving the jaws 11 upon the cap plate. A
The cam plate is provided with a pairl ot similarly constructed grooves; each groove is provided with a primary long portion 21 and an auxiliary short portion 22. ln the grooves are rollers 23 2 and 8), and the auxiliary extensions extend into the rollers 23, so that upon rotating the cam plate 16, through the medium ot the rollers 23 and extensions 15, ot the aws 11, said jaws will be adjusted. ln adjusting the jaws 11, when the cani plate 1G is being rotated tor causing thev primary longl portions 21 to pass-under the slots 7 (Fig. 2). a very slow action or movement of the jaws 11 will be caused, but when the short auxiliary portions 22 are traveling directly under the slots 7, the adjustment oit the jaws outwardly upon the cap plate will be more rapid; the action et the primary portions 2l, acting upon the jaws will be to draw them toward each other very slowly; hence, it will be seen that I have provided a cam plate with two slots, each having portions at an angle to each other, the portion 2l being tor slow adjustment and the portion 22 being for tast or rapid adjustment ot a jaw.
A bracket arm 29 may be fastened to the cap plate by means ot a bolt 30; this bracket arm'29 is used for some Work that is required for close Work Where a tool is sup` posed to pass through the bushing 29u.
ln such Work as does not require the drum Qflf, pin 25, and lool; nuts QG, the samernay be ron'iovedV to permit the work to drop llnough the vise in the box, thus increasing the production of the operator. j
lt is to be understood that the bed plate l and the cap plate l tit closely together to protect the cani plate i6 'from being damaged in operation, and the close-fitting of said parts j )revent chips or dust troni entering therelnetiveen, insuring, by keeping the parts clean, of very eihcient operation.
ln the jaws 1S are horizontal slots 13 made .tor insertion ot different jaws to suit diiierent ivorlc.
The reason olf the slou mot-ion ol`V the jaws, caused by depending projections olf said jaws extending into the portions Q1 oilI the cani plate, is to lock the Work, giving a strong grip to the Worlr, and preventing it `from getting loose in operation.
While l have described the preferred embodiment ot my invention, and have illustrated the same in the accompanying dran'- ings, certain minor changes or alterations may appear to one skilled-in the art to which this invention relates, during the extensive manufacture of the same and l, therefore, reserve the right to make such alterations or changes as shall fairly fall Within the scope of the appended claims.
llfhat l claim is:
l. ln a device oi the class described, the ':oinbination oli' a bed plate, a cap plate provided ivi th an inner and outer annular 'flange resting upon the bed pl ate, the inner flange enga-ging the inner portion of the bed plate and the outer flange engaging the outer Vlace ofthe hed plate, said cap plate provided with a pair oilz ledOes and a groove formed between said ledges, jaws slidably mounted in said groove, and cam means positioned between the bed plate and the cap plate and operably connected to the jaws for adjusting the jaws in the groove when said cam means is operated.
2. In a device of the class described, the combination with a bed plate, of a cap plate resting upon and secured to said bed plate, said cap plate provided With inner and outer flanges engaging the inner and outer portions ot the bed plate, said cap plate provided With a groove in its top and With an opening in its side, a rotatable, cani plate under said cap plate and resting upon the bed plate, a handle fastened to the cam plate and extending through the opening in the side ot the cap plate, slidable jaws positioned upon said cap plate, and means secured to the jans and extending through the cap plate and into the cam plate :for adjusting the aufs when the cani plate is moved by an operator grasping and operating the handle.
3. ln a device o'l the class described, the Combination with a bed plate, oit a cap pla-ie on said bed plate, said cap .plate provided with elongated slots, jaws positioned on said cap plate above said slots, a cam plate under said cap plate, said cam plate provided Wit-h a. pair ot slots, each slot comprising a pri mary long portion and an auxiliary short portion positioned at angles to each other,
said slots of the cam plate registering with the slots in the cap plate, rollers in the slots ot the cam plate, and said jaws provided with integral depending primary portions and With reduced auxiliary portions, the primary portions positioned in the slots or the cap plate and the auxiliary port-ions positioned in the rollers, 'substantially as shown and described.
