JOSEPH KOENIG, OF TVO RIVERS, AND NICHOLAS DEDRICK, OF MANI- TOVOC, WISCONSIN, ASSIGNORS TO THE ALUMINUM MANUFACTUR- ING COMPANY, OF TWO RIVERS, WISCONSIN.

COMB-TOOTH-BEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 648,759, dated May 1, 1900.4

Application filed October 30, 1899. Serial No. 735,201. (No model.)

To all whom it may con/cern:

Be it known that We, JOSEPH KOENIG, a resident of Two Rivers, and NICHOLAS DED- RICK, a resident of Manitowoc, in the county of Manitowoc and State of Wisconsin, citizens of the United States, have invented certain new and useful Improvements in Comb- 'looth-Beveling Machines; and we do hereby declare thatv the following is a full, clear, and exact description thereof.

Our invention has especial reference to the manufacture of aluminium combs; and its object is to provide simple economical self-feedl machines for bevel-finishing of comb-teeth corners, said invention consisting in certain peculiarities of construction andcombination of parts hereinafter particularly set forth, with reference to the accompanying drawings, and subsequently claimed.

Figure l of the drawings represents a Vertical longitudinal section of a machine in accordance with our invention, this view being indicated by line l l in the succeeding figure; Fig. 2, a plan view, partly in horizontal section; Fig. 3, a rear elevation of the machine; Figs. 4, 5, 6,- and 7, detail parts of said machine; Fig. 8, a detail sectional View similar to part of the first figure, except as to position of the comb-carrier therein; Fig. 9, a detail sectional View indicated by line 9 9 inthe preceding ligure; Fig. 10, a perspective view illustrating part of an escapement-movement embodied in said machine, the slip-dog in this view being moved back against an opposing spring; and Fig. ll, a plan View of a finished comb.

Referring by letter to the drawings, A indicates the base of our machine, a portion of the same being higher than the remainder. On the higher level of the base is a guideblock B for a carriage C, that reciprocates in a direction longitudinally of said base, this carriage being provided with lateral studs b, engaged by boss ends of a yoke D, in union with a pitman E, by which it is connected to an eccentric F on a shaft G, that turns in standards H, rising from the lower level of the aforesaid base, said shaft being provided with a pulley I for a driving-belt.

In pivotal connection with ears c of carriage C -is a plate J, provided with-a central slot in a direction longitudinally of the machine, and this plate rests on a spiral spring CZ, seated in said carriage. plate-slot is a lug c, depending from a superimposed cross-plateK, the upper portion of this plate being a guide f for a carrier L, at right angles to the one aforesaid, and a spiral Spring g is supported between said lug and superimposedplate. A set-screw his arranged in a bracket i on a lug extension j of carriage C to bear against a similar extension 7c of slotted plate J, and by adjustment of the screw the normal tilt of this spring-opposed pivotal plate and parts in connection therewith is regulated.

By means of screws m atemplet M is detachably connected to the under sides of lugs n,

tical inner grooves in the lugs is a spacingrack N, said lugs being shown provided with two sets of thevertical grooves in order that the position of the spacing-rack may be varied. Back of the spacing-rack the carrier L is provided with a recess, in which a plate P is made fast flush with the top of said carrier, and extending up from this plate are stoplugs lo, that come in interstices between the teeth of a comb Q, supported on the aforesaid carrier. The comb is held snug against the stop-lugs p by slotted plates q, secured in adjusted position on Athe top of carrier L by setscrews r, engaging their slots, and in pivotal connection with ears s, rising from said carrier, is a comb-clamp comprising angle-dogs t, connected by a rod u with an intermediate hand-lever o, that also constitutes part of the clamp,'said angle-dogs being opposed at their ends farthest from the comb by spiral springs w, seated on the aforesaid carrier.

By the means above specified a comb is accurately positioned on the carrier L, the spacing-rack serving to correctly aline the combteeth, and a feed-,rack R in detachable connection with said carrier coperates Withfast and slip dogs y, supported parallel to each other by a spring-controlled leverS, fulcrumed between its ends to the superimposed plate K, above specified, the lower end of this lever being in opposition to a lug z, ris- En gaglng the that extend from carrier L, and engaging ver- IOO ing from the machine-base. The slip-dog is in slot-and-pin connection with the fast dog on lever S, and a leaf-spring y' is suspended from the upper portion of said lever to oppose one end of said slip-dog.

The mechanism set forth in the preceding paragraph constitutes an escapement for the comb-carrier L, and a flexible runner L', attached at its ends to said carrier, and a weight T is supported by a pulley T', suspended from an arm A' of the machine-base, the latter being provid ed with brackets U, that su pport stop-screws U' in opposition to said carrier, whereby the limit of movement on the part of this carrier in either direction may be accurately determined.

A right-angle bracketV and a standard W on the machine-base serve as bearings for a spindle X, provided with adriving-pulley X', and a head Y, provided with transverse peripheral blades, is made fast on one end of the spindle to constitute a cutter, the blades of which extend through a slot in a shield V', that constitutes part of said bracket, a cover Y' for the cutter-head being detachably connected to the shield. An arm V" constitutes another part of bracket V, and a longitudinally-slotted plate Z is adjustably secured to the arm by set-screws Z in the path of -the templet M, above specified, u

As shown in Figs. l and 2, a comb is positioned on carrier L, and the latter has had longitudinal movement a distance equal to one tooth of the feed-rack R, whereby an interstice between comb-teeth is brought in line with the cutter of the machine. By continued revolution of the eccentricF the carriage C and parts in connection therewith are moved in the direction necessary to feed the comb to said cutter. By contact with shield V' the clamped comb is depressed and carried tangentially to the cutter just within the periphery of same for the length of out, the depth of this cut being equal to the exposure of said cutter through the shield-slot, whereby, owing to proper shaping of the cutter-blades, as best shown in Fig. 9, the otherwise rightangle corners of a pair of comb-teeth are accurately beveled. The length of cut in every instance is determined by the templet M, and when the latter comes in abutment against the stop-plate Z the superimposed guide-plate K and comb-carrier thereon will remain stationary, while plate .l and carriage C continue to travel incidental to a completion of throw on the part of eccentricF aforesaid, the spring g being compressed when this operation takes place.

When the comb-carrying mechanism moves toward the cutter, the spring-controlled lever S has automatic movement to bring the fast dog :o into engagement with the feed-rack R and the slip-dog y clear of said rack. At the same time there is contraction of the previously-expanded spring y to move the slipdog a distance equal to one tooth of the feedrack. Now upon reverse movement of the comb carrying mechanism the lever S is caused to tilt on its fulcruin (against spring resistance) by contact with lug z on the machine-base, whereby the fast dog is moved out of engagemen t'wit-h the feed-rack and the slip-dog /J brought into engagement with the same, thus permitting partial descent of weight T to move the comb-carrier a distance equal to one tooth of said feed-rack, the spacparture from our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. Acomb-tooth-bevelingmachine comprising a cutter consisting of a head having transverse peripheral blades, a comb-carrier, feedregulating mechanism in conjunction with the carrier, means for causing operation of the cutter on and between teeth of a comb upon said carrier, the comb being tangential to said cutter just within the periphery thereof the whole length of each cut, and templet and stop mechanism for regulating the length of cuts.
