CARD-GFHNDER.
SPECIFICATION forming part of Letters Patent No. 379,285, dated March 13, 1888.
(No model.)
To all whom, it may concern:
Be it known that I, BOZIL S. ROY, a resident of the city and county of lVorcester, in the State of Massachusetts, have invented certain new and useful Improvements in Machines for Grinding Top-Flats of Card-s and Similar Purposes, of which the following is a specifica tion.
My improvements are intended to enable the machine to grind much faster by using two or more grinding wheels onv the Same driver and carrier to operate on different parts of the same surface to be ground atthe same time; to make the wheels traverse simultan eously; to provide a buffer to receive and ease the concussion of the wheels at each end of their traverse, so that they can be run at high speed without a shock; to balance the driving shell or arbor by making the cnt side enough thicker than its opposite to balance after the slot has been cut in the thick side; .to save the friction and wear of the T carrier or arm in the slot by inserting a pulley to run in the slot; to give a better inclination to the thread of the traverse screw by making it larger and hollow to relieve the weight; to afford a ready convenient means for adjusting each dat to the Vwheels and readily removing it temporarily to adjust the others, and readily returning it to place without varying its adjustment; to provide a convenient means of brushing or cleaning the teeth of the dat to be ground the whole length at once; to compensate for the wear of the brush by the use of adjustable stops for holding the flat against; to provide means of adjustment to grind the face of the dat as desired by pivoting the holders and setting by means of curved slots and screws, and also to take up the wear of the slides of the holders by the use of gibs with screws and cheek-nuts.
The details of said improvements and their operation are fully set forth in the description of the accompanying drawings ofthe main parts of a machine embodying my invention, the parts claimed as new being especially designated in the claims.
In said drawings, Figure l is aperspective view with the main parts in place. Fig. 2 is a view of a holder removed from the frame as seen from the inside or left of Fig. 3. Fig. 3 is a side view of the same as seen from the right of Fig. 2. Fig. 4 is a view of the Same from the right of Fig. 3, the opposite to Fig. 2. Fig. 5 is a view of the end or bottom of Fig. 3. Fig. 6 is an end view of the slide to which the holder is attached. Fig. 7 is aside view of the same'or plan. Fig. Sis a view of the same in a portion ofthe frame adjoining. Fig. 9 is a side view of a chain traverse motion as seen from theleft of Fig. ll, with a portion of the shell removed to show the inside mechanism. Fig. 10 is a central longitudinal section of the shell showing the chain-carrying mechanism taken at Vright angles to Fig. 9. Fig. ll is a cross-section of the same as of Fig. 9, near the hub G, as seen from the right, (one portion only of the hub being shown.) Fig. 12 is a side view of a portion o f a screw traverse motion with a part of one end in central section.
The same parts are indicated by the same letters wherever they occur.
P P are the ends of the main frame, supporting in suitable bearings the shaft O and wheel driver F, the former receiving motion from the pulleys O3, and giving the necessary niotion to the wheels G G by belts from pulleys O2 to F3 and O5 to F2, or other suitable means.
E E is a secondary or upper frame having slots E i', in which the swivel-bearing slides D D are fitted, which carry the holders A A, motion being given to the slides D D by connection from their pins DZD2 to the eccentrics N 2 Nl (said connections not shown) on the shaft N, hanging in the lower part of the frame E E, and receiving motion through the gear N 0 from shaft O.
At M is a cleaningbrush supported in suitable bearings and made long enough to clean the whole length of the card-ilat 7 and driven by belt on pulleys M O4, and infront of it, on the girth P', are two adjustable stops, Q Q, held by screws in slots to be adjusted to or from the brush M. v'lheseformboth rests and stops against which the dats 7 are held for cleaning, so that the whole length is cleaned at once, and as the brush wears the stops are reset toward it, keeping it in good working order.
The holders A A are held on their pivots D3 on the slides D by the screws D4, which pass th rough the curved slots A6 and allow the hold-,l
ers to be adj usted to hold the dat so that its face shall be ground as desired, whether parallel to its ends or at an angle.
The holder A carries a slide, A', adjustable by the screw A2, having a check-nut, A3, the slide A having a slide, B', and a stop, B2, against which it is held by the thumb-screws B4 when the machine is grinding, the slide B carrying the socket C, in which the end ofthe fiat is held by the screw C', the slides D D being fitted in the frame E with agib, E2, having adj ustingscrews E3, with their checkhuts, whereby any looseness by wear can be adj usted.
Figs. 9 and 10 illustrate a method of driving two wheels by the well-known chain trav erse motion, by giving a motion to one by the T-piece G2, attached to the hub G ofthe wheel, and connecting this wheel to another by the rod G', between the two hubs G G and in the slot of the driver, so that both wheels have the same motion, the chain motion being made the length of motion for one wheel. Thus any number of wheels can be used, and when a screw is used to give the traverse motion it may be made short, as the motion of' one wheel, or stops K used, as shown in Fig. 12,
and the wheels connected by a rod, or in the latter form of screw, they may have separate carriers traveling in different parts of the same screw K, which is made large to give an easier incline to the screw, and hollow, as at K, to avoid increase of weight. The piece G2, attached to the hub G of the wheel and niov ing in the slot in the driver F, hasa pulley or roll, G, moving in the slot to prevent wear. The driving-shell F is made enough thicker on the side to be slotted, (see Fig. 11,) so that when the slot has been cut and all parts are in place a perfect balance shall be preserved.
The heads F or ends of the driver are provided with a projecting recessed flange, F4, for receiving an elastic ring, F5, or buffer, against which thehubs Gstrike at the end of the traverse motion. These are most needed when a screw is used to give that motion, and serve to greatly lessen the shock in running quickly.
In operating the grinder the teeth of the l fiat are rst cleaned by its being held up to the stops Q Q, so adjusted that the brush M cleans them effectively the whole length at once. The dat is then placed with its ends in the sockets O. The holders A having been set by their screws D4 in the desired position and the slides B set to the stops B2, the ends are 5o secured by the screws C' firmly, and motion having been given to the wheels G G, the iiat is moved to the desired position to grind by the screws A2 at each end, and secured by their check-nuts. If only one is to be ground, all is ready; but to grind more the first is drawn back from the wheels by turning the thumbscrews B4, drawingthe slide B back from its stop B2, so that the noise of its grinding shall not interfere with the setting of the 6o second fiat in its place, as the proper bite7 or grind ofthe wheels on each atis best judged by the ear or sound. The second being set, it
'is in turn withdrawn to set the next, and so on till all the holders are set, or as many as are to be ground at once, when all are quickly replaoedby the thumb-screws back to their stops, all grinding at once. Thus any number may be quickly and accurately set and ground, the drawings showing au arrangement for four, 7o though more or less might be used.
Having thus fully described my invention, what I claim therein as new, and desire to patent, is
The eccentric-shell driver, made thicker on its slotted side to preserve its true balance, substantially as set forth.
BOZIL S. ROY.
