UNITED STATES PATENT OFFICE.

CHARLES B. PARKER AND ONESIPHARUS B. PARKER, OF SOUTH HADLEY, ASSIGNORS OF ONE-THIRD TO BENJ. P. GLOVER, OF HOLYOKE, MASS.

CARDf-GRINDER.

SPECIFICATION forming part of Letters Patent No. 277,604, dated May 15, 1883. Application tiled December 1, 1882. (No model.) n

To all whom it may concern y Be it known that we, OHAs. B. PARKER and ONESIPHARUS B. PARKER, citizens oi' the United States, residing at South Hadley, Hampshire county, Massachusetts, have invented a new and useful Improvement in Reversing Mechanism for Gard-Grinders, 0i" which the followingisa specification, reference being had t0 theaccompanying drawings, which are ro hereby made part ofthe same.

Similar letters of reference in the drawings indicate corresponding parts.

Theohjectofourinveniionistoruntheemerywheel much more rapidly than it can now be run, and to reverse its motion or travel at any given point on either a cotton or woolen card, grinding the doffer and cylinder at the same time. The manner in which this vis accomplished by our invention we will now proceed zo to describe.

Figure l is a front elevation of the grinder. Ais an emery-wheel. B is the shaft which carries the emery-wheel, and B is the pulley which drives shaft B. b is a spline in shaft B. b is a feather in the emerywheel, which slides in spline b. b3 is the collar on shaft B. C is a double-thread screw, which moves the emerywheel backward and forward. c is a collar ou4 shaft C. D is a guide-rod, which reverses the 3o travel of the emery-wheel. d d are the stops on rod D. d is a set-screw which holds the said stops. d2 is a spiral spring on rod D, which is compressed against the stops d d by arm h2, and throws the clutch hy its recoil. E E are the standards forming the bearing for the three shafis B G D. e is hearing for the shaft E. e is the fulcrum-piu by which the grinder is attached to the stand on the frame of the card. c2 is said stand. F F are the 4o pulleys for driving the screw C. F2 is the clutch. fis a clutch-catch in pulleys F F, shown in detailed views, Figs. 5 and 6. f4 is the groove in clutch F2. ff2 are the catches on the opposite sides of clutch F2. (Shown in Figs. 3 and 4..) f3 is spline in the clutch F2. 45 H is the nut on shaft C, which traverses the emery-wheel. h hare the arms on the n uts, which engage the emery-wheel on opposite sides. h h are the pins which form the thread in the nut H. There are eight of these-four 5o on each side. h2 is the arm on nut H, which reverses the motion of the emery-wheel by striking the stops d d.' I is an arm on the shaft D, which engagesthe clutch F2 and reverses it whenever the rod D is changed. t' 55 is a set-screw, which fastens arm I to the rod D. L is the doit'er-cylinder on the card. l is the shaft of cylinder L. l Z2 are pulleys on shaft l, which drive screw C by belting onto pulleys F F. Z3 is pulley on the opposite or 6o lett end of shaft l, by which the cylinder L is driven. Ois the main card-cylinderot` thecard. ois thepulley on shaft of cylinder O, from which the doi'er-cylinder L and emery-wheel shaft B are driven. t' is a crossed belt from pulley 65 l to pulley F'. t2 is an open belt from pulley l2 to pulley F. I

Fig. 2 is an end elevation of our invention. Figs. 3 and 4 are detailed views of the clutch. Figs. 5 and 6 are detailed views ofthe clutch- 7o pulleys. Fig. 7 is a front elevation of a card with grinder attached. Fig. S is an end ele vation of the same. Figs. 9, 10, 1l, and l2 are details.

Having thu-s described our invention, we
