.Be it known `that l, PI-IILo S. Bruins, of Hamden, `in the county of New Haven and State of` Connecticut,haveinvented a new and useful Machine for Manufacturing Car-` riage-lVheelfSpokes and other Similar Articles; andlhereloy.,declare` that the followngis a` fulland exact description of the construction and operation ofthe same, reference being had `to the annexed` drawings,` making part of thisspecification, in which y. y Figurel is afront elevation; Fig. 2 is' a transverse elevation`ofthe right end.` ofi the machine; Fig. 3 a transverse elevation of the left end of the same; Fig. 4 is ahorizontal section, showing the form and position of the cutter-cylinders and driving` belts; Fig. 5 is a` vertical view ofthe `sliding carriage;A Figs. 6 and 7 represent two com-pound cams, as seen from the right; and
Figs. 8 and i9 are perspective views ofthe two ca1n-rails.\\` n f The several partsof the machineA are designated bythe same letters in all the dilferent drawings. i i l Thenature of this invention consistsin such a combination` and arrangementof va-` rious `mechanical devices, in one machine', that a1 piece` of rough timber ofconvenient size, beingqadjusted therein, and""subjected to theaction thereof, is quickly reduced to the `complete form of a carriage-wheel spoke (or such similar article as may bei required) and that without any lateral or longitudinal motion of either ,thecuttersyorvof the rough material. i
Three cylinders A B C, are mounted upon three horizontal shafts@ b c, which have their bearings upon the two upper sidebeams (D D) of a` square frame, which consists of four posts connected by nine horizontal beams. The surfaces of the three cylinders are furnished with cutters e c, which are so arranged that no two cutters will take to the rough material at thesame time. The surfaces of the cylinders arenot straight, or, otherwise, the cutters are adjusted at unequal distances from the axles of their respective cylinders, and are made to vary in a manner to favor the production of the peculiar form required. A narrow hoop or flange Z extends around the long withpulleys toreceive the bands iscrews pass, the distance between the two` iguide-rails `mayQbe regulated as `occasion )may require.) Upon these guiderails is mounted: a sliding carriage, (see Fig. 5) consisting of `a :vertical head-frame, (H j 70 Z) vtwo horizontal `slides II, two able cross-bars J MJ, and ,undulating rods IK K, the rear ends ofwhich are connectedto two` small studs g g, which are attached to theslides-tThe 'cross-bars J J, and front"` i aIeeach composed-.oftwoiparts which are connected ,bymeans of set-screws .bars H H,-
iwhich pass through` the slots m, that the breadth :ofi the sliding frame may be adjust- 1 ged as* circumstancessrequire. To the headiframe are attached fourhangers i j Z4 Z,j and )a horizontal cam-shaft Lhas its bearings in` these hangers, and extends beyond)V the headframeon lthe-right, `far enough toreceive and support `one of the .comptmnd.cams iM M. v The othercainis mounted upon the cam-shaft between the hangers j and 7c; and? upon the left fend 'of this s`haft,. is mounted thegear-wheel N. `Anotherequal gear-.wheel O,is mounted uponcanother shaft, directly under and parallel .to` thel cam-shaft,and`
which has its bearings in the hangers z' and 7c. To the right end of this shaft, is attached a spur chuclr (or swallows tail P, which is furnished with projecting spurs for holding` one end of the rough material Q,
the other end of which is supported by the centerpoint of a sliding center-bar R. This center-bar is occasionally moved to the right or left, by means of a bent `lever, n and hand lever Sf The lower end of the bent lever (which `is partly represented by dotted i lines) enters a notch in the top of the center- "bar, and the upperend thereof passes between the two branches 0 o of the hand lever. The left end of the hand-lever is furnished with a knob or handle, and has suf-` ficient weight to cause the lever a to press the center-bar against the rough material.
The gear-wheels N `and `O are connected lby a small center wheel or pinion p, upon the axle of which is a pulley s, over which passes a band which also passes over two conducting pulleys g g, and a driving pulley which is mounted upon the left end of a horizontal shaft T. Upon this shaft, near the left bearing thereof, is mounted a bandwheel U, from the left side of which projects a pin h, which occasionally clutches to a pin which projects from the shaft; otherwise the wheel turns freely upon the shaft. In the hub of this Wheel, on the right thereof, is a groove which receives the end of the arm 1, which is attached to, and projects from a sliding block, which slides upon a horizontal rod, parallel to the shaft T. To this block is attached another rod which extends to the right, and is connected to the bottom of a vertical hand-lever Z, by means of which the Wheel U is conveniently clutched or relieved.
To the outside of the guiderails are attached four posts u u, which are adjustable by means of slots and set-screws near the bottoms thereof. To the heads of each pair of adjustable posts, is attached a camrail, V and W, (see Figs. 8 and 9). The cams`M M-rest upon these cam-rails; and the head-frame, with its gear-wheels and rough material, is thereby sustained; the vertical positio-n of the lat-ter being governed by the positions of the cams upon the rails. Near the rear posts of the frame is a driving shaft on which is mounted the driving wheels X Y Z; and on the left end thereof is a pulley to receive a band by which the machine is put in motion. One of the horizontal slides I is grooved in the under side thereof, whereby it is guided upon the rail. In front of the cylinder A is a curved shield or fender, to protect the operator from the detached chips.
Operation: A piece of timber of convenient size being adjusted upon the spurs and center point, and the machine being put in motion, the sliding frame is moved rearward by the hand of the operator till the position of the rough material is over the cylinder A, where it remains till the timber has revolved at least once, during which time, the shoulders u u of the cams, rest upon the sections v of the cam-rails. The sliding frame is then moved back till the timber is subjected to the action of the cutters of the cylinder B, during which the shoulders fw of the cams, rest upon the sections m of the cam-rails, whereby a tilting motion of the timber is produced, and the timber is reduced to the peculiar fornirequired in spokes, near the square tenon. The timber is neXt subjected to the action of the cylinder C, While the cam-shoulders u and y rest upon the sections a of the camrails, by which the square tenon on the left end of the timber is formed. By employing cylinders, cams and cam-rails of slightly different forms'from those herein described, aXe-helves and other similar articles may be made.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
1. The three cutter cylinders A, B, C, (with cutters arranged as within described,) in combination with the sliding frame, compound cams and cam-rails, constructed and arranged substantially in the manner, and for the purpose herein described.
2. I claim the combination of the compound cams, and carn-rails, with the sliding frame and devices (within described) for holding and revolving the timber material, whereby such vertical motion is produced in the latter, while being subjected to the action of revolving or vibrating cutters, as to reduce the timber to the required form.
