FEED MECHANISM FOR WOOD-WORKING MACHINES.

SPECIFICATION forming part of Letters Patent No. 428,284, dated May 20, 1890.

i Application filed December 31, 1889. Serial No. 335,476. (No model.)

To all whom iz? may concern:

Be it known that I, CHARLES J. OLSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed Mechanisms for Woodhas for its object to provide a construction whereby the rate of feed may be conveniently changed or varied at the will of the operator, so as to enable the cutters to which the stuff is being fed to work with greater smoothness over cross-grained or knotted places that may be encountered in a molding-Strip or board being cut or planed.

In the accompanying drawings my invention is illustrated in connection with portions of a molding-machine, and from the following description of the drawings the nature of the invention will be fully understood.

In said drawings, Figure l is a side elevation of an adjustable feeding mechanism embodying my invention, the frame of the Inachine to which it is applied being shown in vertical section. Fig. 2 is a plan View thereof.

A representsa portion of the frame of a molding-machine, of which A is a Adrivingshaft and B is the feed-shaft, the end b of which works over the feed-table C.

D is a fiat-faced wheel secured to the Shaft B.

E is a shaft mounted in bearings e e on a suitable frame, which may be the frame of the planing or Inolding machine, said shaft E being provided at one end Wit-h the beveled gear-wheel e', which meshes with the beveled wheel a upon the shaft A. To the opposite end of the shaft E is connected a shaft F by a universal joint f, and the opposite end of said shaft F is mounted in a journalbox F, which slides laterally on a guide G, provided On the upright C, here shown as rising from the machine-frame. On the shaft F is tit-ted a wheel H, adapted vto slide lengthwise on the shaft F, but held from rotation thereon by suitable means-as, for example, a feather.

(Seen at f.) The Wheel I-I, as preferably constructed, has a cylindric or practically cylindrie portion 72, adapted to bear againstthe flat face of the frictionwheel D, and also a conical part h', while said friction-wheel D has a conical or beveled portion d at its margin conforming to the inclined surface of the cone h.

By means of a hand-lever I, arranged in convenient reach of the operator, as shown in which the invention is applied. In the present instance said lever is mounted on'one end of the shaft I', to the other end of which is secured an arm t', which connects by Aa link t" with the end of a sleeve h2, that proceeds from the small end of the cone h', the con'- nection of the link t" with the sleeve being by means of a strap i2, fitted to rotate in a groove near the end of the sleeveA In order to cause the cone-wheel I-I to press against the Wheel D in any position of said cone* wheel, the slidin g journal-box F Which runs on the lateral guide G, Yis supplied with a weight J, connected with the journal-box by means of a chain or cord j, trained overk a pulley g', located at the end of the guide G. By means of this weight the cone-wheel II imparts motion to the friction-Wheel D, against which it bears, and the speed of said friction-wheel and of the feed-shaft B Will of course be variable according to the position of the cone-wheel on the shaft F-that isl to say, when the cone bears at its smallest diameter against the beveled surface of said wheel D, it will drive Said wheel at the lowest speed, and when the cylindric portion h of the cone bears on the flat surface of the Wheel D nearest the center of the latter the feed-shaft B will be driven at its highest speed. Intermediate speeds of the feed-shaft will be obtained by giving the cone-wheel H IOO positions intermediate to those mentioned. Thus by the lever I any desired Speed may bie given to the feed-shaft according to the character of the stuff the operative is cutting or shaping and according to the variations in the grain of a particular' piece passing through the machine.l By throwingthe cone forward on the shaft F far enough to entirely clear v second cone the feed-shaft B may be reversed v in its direction of motion.

vIn diiierent .mach'ne'sV the details of oo nl. struction .of the feed mechanisnidescribed, andparticularly the arrangement of its parts withrefe'rence to the general elements of the machine to `Whichit'is appliedrwillbe varied l and the friction-d iskD, driving the saidfeedshaft, of -a laterallymovable revolving' shaft according to circumstances. In the present instance an arrangementis shownadapted to a common form of molding-cutter. It will be understood'tliat I am not restricted to the particular arrangement'of the parts or tojthe details of construction herein illustrated, in asmuch Vas I desirel to hold the invention' in its application kto any' form oi"y machine to whichit maybe applied and With ,such Variany invention I Vmy signature in pres ile'nce oftwo `witnesses.

combination, with a driving-shaft fromwhich the. cutters are to be driven at a uniform speed, of a feed-shaft connected With the 'a beveled surface at' its margin, and -for holding the cone-wheel in pressure against :the disk D, substantially as described.
