JACOB R. SOOTT, OF NEV YORK, N. Y.
SKlVlNG-MACHINE.
SPECIFICATION forming part of Letters ratentNo. 453,944, dated June 9, 1891.
Application filed February 26, 1891,- Serial No. 382,965. (No model.)
.To all whom t may concern:
Be it known that I, JACOB R. SCOTT, a citizen of the United States, residing at New York, in the county and State ot' New York, have invented new and useful Improvements in Skiving-Machines, of which the following is a specification.
This invention relates to certain improvements in skiving-machines as pointed out in the following specification and claims and illustrated in the accompanying drawings, in whichy Figure l is a front elevation, partly in section. Fig. 2 is a side elevation. Fig. 3 is a plan or top view. Fig. 4 is a transverse vertical section in the plane 0c 0c, Fig. l. Fig. 5 is a horizontal section in the plane y y, Fig. l. Fig.,6 is a plan view of the clamp detached. Fig. 7 is a plan view of one of the tables detached.
In the drawings, thc letter A designates a frame or standard, which forms the bearings for a shaft B, on which are mounted the cutters C O. These cutters co-operate with tables D D', which are movable toward and from the cutters and also in a direction at right angles to the axles of said cutters. In the example shown in the drawings said tables are made in the form of segments of a circle and each is provided with a shank a a', having an eye b b', respectively, said eyes being bored out to fit screw-studs d d. These screw-studs are secured in or extend from slides ce', which are adjusted on rods f f by means of set-screws g g. Said rods slide up and down in eyes h h', formed on arms which extend from the standard A. The slides ee bear against face-plates t i', the shanks ot which tit into a socket j in the standard A and are adjusted therein by means of set-screws k 7e. (Best seen in Fig. 5.) The lower ends of the rods ff connect wires ZZ with treadles (not shown inthe drawings) and they are exposed to the action of springs m m', the upper ends of which bear against collars'n n', which can be adj usted upon the rods f f by set-screws, so that when the treadles are depressed the tables D D are moved away from the cutters C O and when the treadles are released the tables are forced toward the cutters.
In Fig. l of the drawings the table D is shown in its lowest position away from the cutter, and the table D is shown in its working position close to the cutter. The lower ends ot' the rods ff are provided with screwthreads to receive nuts o o', by means of which the ,upward movement of the tables can be adjusted. Then the rods ff are permitted to follow the action of the springs m m', the nuts o o enter into cups p p', provided on the arms having the eyes 7L 7L', for the purpose of preventing chips, impurities, and other matter from lodging upon the nuts.
On the top of the standard A are secured guard-plates E E', which ext-end over the cutters C C, and on the sides of the standard A are secured slides F F', (best seen in Fig. 4,) which carry rollers q q', and which can be adjusted by means of set-screws r yr', tapped into the guard-plates E E. The rollers q q stand opposite the tracks s s', formed on the inner edges of the t-ablesD D', and the slides F F are adjusted so that the tables can approach the cutters to the exact distance desired.
Each of the tables is provided with a clamp G G', a detached plan View of one of which is Shown in Fig. G. These clamps swing on pivots t t', Figs. l and 2, and each is provided with a handle u u and with a clamping-pad o 'ot' rubber or other suitable material. From the tables extend arms w w', Figs. 2 and 7, which form the bearings for a rock-shaft carrying au eccentric a2 anda crank b2, and when this crank is turned to the position shown in Fig. 2 the clamp is raised so as to release the work; but if the crank is reversed the clamp can be depressed so as to retain the work firmly upon the table. From the handle uit of each clamp extends a rope c2 under a pulley d and over a pulley e2, and from each ropeis suspended a weight f2, Figs. l and 2. After the work has been properly adjusted on each table the eccentrics 0,2 are turned, so as to allow the clamps to move downward, and the weight]c2 draw the clamps up tight. against the work, and at the same time the tables are caused to swing by the action of said weights in the direction of arrow l, Fig. 2, so as to draw the work. forward while exposed to the action of the cutters. A stop h2 limits this motion of the tables. The pulleys e2 are mounted in a bracket y?, which is secured to the standard A, and the pulleys (Z2 are mounted in arms d3, extending from the eyes l) b. The surfaces of the tables D D are provided each with a cavity (Z0 do', respectively, the shape of which depends upon the article to be skived.
The machine illustrated in the drawings is intended particularly for skiving counterstiifeners, and the cavities do d0 are inverted, so that after one half of a counter-stiiener has been skived on the table D, said stiffener can be reversed and its remaining half can be finished on the table D.
From this description it will be seen that by means of my machine a single person is enabled to skive simultaneously two counterstiieners or other articles, since the tables, afterthe work has been adj usted and clamped upon them, are drawn forward Linder the cutters automatically by the action of the weights f2, and all that the attendant has to do is to lower the tables and to adjust the work on the same.
That I claim as new, and desire to secure by Letters Patent, is-
1. The combination of a standard, a shaft mounted thereupon and provided with a cut ter, a work-supporting table movable toward and from the cutter and also at right angles to the aXis of the same, a work-clamp carried by the table, and automatically-operating devices, substantially as described, which move the table in one direction and simultaneously therewith aetuate the work-clamp to clamp the work on the table.
2. The combination of a standard, a shaft mounted thereupon and provided with a cutter, a work-supportingtable movable toward and from the cutter and also at right angles to the axis of the same, awork-elamp carried by the table, a cable connected with the work-clamp, cable-guides, and means acting upon the cable to pull it lengthwise, and thereby move the table in one direction and simultaneously therewith cause the workclamp to clamp the work on the table, substantially as described.
3. The combination, with the cutter C and the table D, of the guard-plate E, the slide F, the roller q, mounted in said slide, the setscrew r, mounted in the guard-plate, and the track s, formed on the table, substantially as described.
4. The combination, with the standard A and with the shaft B, of a cutter mounted on said shaft, the oscillating table D, mounted on the stud d', the clamp G, connected to the table by a pivot t, the pulleys d2 e2, and the weight f2, suspended from a rope c2, which is connected to the handle u of the clamp and extends beneath the roller d2 and over the roller c2, substantially as described.
5. The combination, with the work-supporting table, of a clamp connected to the table by a pivot, a weight for swinging the clamp toward the table te clamp the work, and a cam er eccentric carried by the worktable for moving said clamp away from the table, substantially as described.
(3. The combination, with the cutter and with the vertically-moving table, of a spring, a collar for adjusting the upward thrust of the spring, an adjusting-nut for limiting the upward movement of the table, and an overhanging cup which receives and protects the nut against impurities, substantially as dcscribed.-
In testimony whereof VI have hereunto set my hand in the presence of two subscribing witnesses.
JACOB R. SCOTT.
