i `Letters Patent No. 105,860, dated July 26, 1870.
IMPRovnMENT 1N cHUcKs.
l'he Schedule referred n these Letters Patent and making part of the same.
tain Improvements in Griping-Ghucks, ot' -which the following is a specification. y Y l The nature of my invention consists in the-combination and arrangement of a hollow slide and toothed,
wedge with thebody of the chuck, in such a manner as to providefor the `piece to be chncked being placed between double angular cheeks of the slide, which bite itvon one side, and a toothed edge of the wedge, which bitesit on the other side.
The wedge is connected with the stationary part vof the chuck by means'of tongues and grooves, and also with the slide, by means of' angular grooves and tongues, which slide iii-,the same, in such a manner that, when it is driven forward, ittightly gripes the piece to be chuckcd, as hereinafter described.
In' order to keep'the chucked piece in its central po` sition with the chuck, the guiding ribs'of the wedge are 4placed at an angle., with the 'griping-edge of the same, of one-half the degrees assumed'by the angle of `the grooves in the slide. i
The wedge 'is so arranged with the chuck that its forward or tightening motion shall bein the linefot'- 'i motion of ,the chuck, so that the actionof 'the lat-ter shall tend to increase the gripe of the device.
Toenable others skilledin the art to which my invention appertains to apply the same to practice, I will now give a detailed description thereof.
In the accompanying drawing, which makes apart Figure 1 is `a face View of the improved chuck. y Figure 2 is a likeview of the interior, the cap-plate Bv being removed.
Figure 3 is a cross-section at the line x :c of iig. 2i Figure 4 is a like view at the line y 'y of fig. 2,. -iligure 5 is an isometrical view of the hollow griping slide O. I Y i Like letters in all the figures indicate the same l parts.'V
A represents the body of the chuck, which has a cap-plate, B, confined by means of screws a.
Between the standing plate b and the said cap-plateY B and the parallel ribsd d is situated a hollow slide,
l ,0, which is seenin detailin iig. 5.`V
The said slide has cross-slots ff through its longitudinal opening g, to admit of Ya piece to be chueked passing through, as vit is placed centrally in the chuck, in the center openings h 71., and also for the formation of the double inclines j j, for griping the ba-r to be checked. o y Y l The slide also has cross-openings 7c k, at right angles to the openings f f, to admit of the passage of th'e griping-wedge D, having inclinedlugs ll on its sides, which move inthe inclined grooves m m of the slide C, and also'inclined ribs 'n n, which move in and `are guided bythe cross-grooves o o, in' the sides of cross-slots pp of thejribs d d.
'lhcrc `are slots q q on the opposite edges ofthe' chuck A for the free passage of the wedge D.
When the rod to be chucked is placed in position, and the wedge D is forced in thedirection of the arrow, the slide C is drawn forward, bringing the double inclines jj, at each side of the slide, against one side of the rod, and the toothed edge s of the wedge against the other side, so as to tirrnly gripe the rod.v
When the latter h as to be removed from the chuck, itis loosed by backing the wedge D.
The angle formed by the toothed edge s of the wedge D a'nd the ribs n 1t is just one-half as great as that of the "grooves m m of the slide, so as to preserve the-central position ot thel rod in the grping" operation.
For other 'purposes than chuckiug, the wedge and slide may be used to gripe a. rod or other piccewithout the use of the standing parts A B. In this case I give an extension t9 the forward end of the wedge, -toform a handle for operating the same.
What I`claim as'my invention, and desire to secure have hereunto ,set my hand andaflixed my seal this 13th day of June, 1870.
