APPARATUS FOR CONTROLLING THE GRINDlNG OF FLATS OF CARDlNG-ENGINES.
SPECIFICATION forming part of Letters Patent No. 519,771,dated May 15, 1894.
Application filed February 1, 1894. Serial No. 498,759- (No model.)
and are arranged in endless chains, the wire being ground from their working surfaces without removing them from their position on the carding engine. 7
The invention consists essentially of aslidingor moving block adjustable as to inclination or angle at its ends by means of adustable slideways which support the ends, whereby the block or slide may be adjusted to the angle of the bevel of the flat and grind the wlres to an exactly even length by slides which areindependent of the grinding mechanism and adjustable, all constructed substantlally as described below, and illustrated 1n the accompanying drawings, in which- Figure l is a side elevation of my device, a sufficlent portion of a carding engine being shown to illustrate the operation of the invention Fig. 2 is a sectional view,-the sec- 131011 belng taken vertically,looking from the inslde, a portion of the grinding roller bemg represented as broken out. Fig. 3 is a cross vertical section. Fig. 4: is an enlarged elevation looking from the inside, a portion of the sliding block being represented as broken out. Fig. 5 is a vertical section taken on line 00, Fig. 4.
Similar letters and figures of reference indicate corresponding parts. a represents the grinding roller supported 1n hearings in the adjustable or extensible bracket 12 secured to the bend d, all as now common.
e is a weighted lever, f being the weight, pivoted at g to the bracket band formed into the shape shown at e for the purpose of successively lifting up each fiat to be ground; not new in this invention.
h is a screw for adjusting the height of the lever.
k is the cylinder, and Z is an ordinary endless chain carrying the flats A over the guide or track m andover the part c of the weighted lever which holds them up to the grinding roller a, in accordance with a well known principle or plan in grinding flats.
Secured to the bracket b is the horizontal bracket or frame B.
Pivoted at 1 and 2 respectively are two slideways O O, inclined as shown, the angles of inclination being arranged by the vertical screws D D which turn in the frame 13 and set against the upper and under sides of blocks 0' O projecting into the arc-shaped openings B in the frame B and pivotallysecured at O G to the slideways. Thus the operation of the screws sets the angles of the slideways by allowing them to swing on their pivots 1 and 2. Each slideway is longitudinally grooved at c, and in each groove moves a sliding block E, said blocks being pivotal ly secured at E to the opposite ends of the substantially horizontal sliding bar or sliding grinding block F. The under side of this sliding bar F is provided with an integral lug or projection F, the face of which is substantially at right angles with the bottom of the sliding bar but the rear side of which is at an obtuse angle therewith.
Pivoted at I within a recess or vertical hole in the sliding bar F is a bell-crank lever H whose lower arm is provided with a foot H. A spiral spring J has its ends secured to the frame B at J, and to the sliding bar F by means of the bracket J The operation is as follows: The sliding bar F is held normally toward the left, as shown in full lines in Fig. 4. Afiat A advances, being carried by the chain Z. It strikes the projection F, and, while being forced up the incline e of thelever e, carries the sliding bar along into the position shown by broken lines in Fig. 4 and full lines in Fig. 2, and is ground by the wheel a. As the sliding grinding bar F moves toward the right, it mounts the inclined slideways C and the upper arm of the lever H strikes a horizontal arm or projection L (Fig.3.) extending from the upper edge of the frame B, and said arm is hence depressed to pass under it causing the foot H to be pushed down upon the surface of the fiat until the latter is forced below the projection F,instantly freeing the grinding bar F and allowing it to be pulled back from the position shown in broken lines in Fig. 4 into the position shown in full lines in said figure, ready to be engaged by the next flat.
As will readily be seen, the screws D enable the adjusting blocks G to be raised and lowered at will independently of each other and of the grinding bar and mechanism. Thus the direction of the movement of the sliding or grinding barF may be determined and adjusted to a high degree of exactness, so that the grinding line may be exactly parallel with the top surface of the flat without regard to the incline on the end of the flat, such incline being the part which is pressed upagainst the under side of the sliding bar F. In other words, the ends of the sliding grinding block are independently adjusted to the angle of the bevel of the flat.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. An apparatus for controlling the grinding of flats of carding engines, comprising a sliding grinding bar or block against which the flat bears as it is guided to the grinding roller, and independently adjustable sliding supports for the ends of said bar or block, whereby the direction of the movement thereof may be adjusted to produce and correspond with the line of direction of the grind,- ing of the flat, substantially as set forth.
2. An apparatus for controlling the grinding of flats of carding engines, comprising a sliding grinding bar or block against which the fiat bears as it is guided to the grinding roller, independently adjustable sliding supports for the ends of said bar or block, and rotative slideways for said supports pi'votally secured to a frame and adapted to be set at different radii, whereby the direction of the movement of the bar or block may be adjusted to produce and correspond with the line of direction of the grinding of the fiat, substantially as described.
3. The apparatus herein described for con trolling the grinding of flats of carding engines, comprising the frame B, the slideways O o pivoted thereto, the grinding bar or block F pivoted at its opposite ends to blocks E moving in said slideways, means for adjusting the angles of said slideways, and the flats adapted to be guided to and held against the under surface of the grinding bar, substantially as set forth.
