lVIACl-llNE FOR FINISHING BROOM-HANDLES.

SPECIFICATION forming part of Letters Patent No. 348,878, dated September 7, 1886.

Application filed Api-i122, 1886.

To all whom, it may concern:

Be it known that I, HARRY C. ALEEE, of Detroit, in the county of \Vayne and State of Michigan, have invented new and useful Improvemcntsin Machines for Finishing Eroom Handles; and I do hereby declare that the following is a full,'clear, and exact description thereof, reference being had to the accompanying d1awiiigs,\vhich form a part of this specification. l

This invention relates to a new and useful improvement in machines for finishing broomhandles; and the invention consists in the peculiar construction and arrangement of different devices, and in their colnbinatiou into an operative machine, whereby the sticks after they are shaped by the turning-lathe are provided with a rounding head and with a sawkerf (or a hole) near the butt-end ofthe stick for fastening the ends of the wire used in the further manufacture of the brooms. Y

To this end my machine contains the following elements: A feeding device, a clamping device for holding the stick while being operated upon, a saw on a swinging arbor for making a saw-kerfon the butt-end of the stick, (or, as an alternative, a boring-tool fol-boring a hole into the stick,) and a reciprocating cutter-head for rounding the head of the stick, the parts being constructed, combined andarranged to operate automatically, all as hereiuafter described.

In the drawings,which accompany this specification, Figure l is a plan of my machine. Fig. 2 is a plan ofthe main shaft, showing the cams secured thereon and which aetuate the different parts. Figs. 3, 4, 5, and 6 are crosssections on the lines a; 7/ y, z z, o o, respect` ively. Fig. 7 is an elevation of the swinging saw-arbor and its operating connections. Fig. 8 is a plan of a boring-tool arranged in place instead of the saw shown in Fig. l.

A is a bench or frame supporting all the different parts of my machine.

3 is a box or rack supported upon this bench. It forms a vertical well, C, of proper dimensions to hold in regular order a number of sticks, one on top of the other, as shown in the drawings. This well is open on top and bottom and maycommunicate on top with a hopper or other device for feeding the sticks into the well, or they may be fed by hand.

rIransversely below the bottom of the v9.11

Serial No` 199,776. (No model.)

are placed two or more horizont-al sliding bars, D, which are held in suitable guides, E,fse cured upon the bench in rear of the well and prevent the sticks from falling out. These sliding bars are provided at their forward ends with rests a, which drop below the plane of the bar, and are suitably rounding to receive and support a stick. The bars D are reciprocatingl y actuated in any convenientmanner, such as shown in Fig. 4, wherein such rcciproeation is obtained by the action of` the cam G, lever F, and springs H, aduplication of this device actuating the other bar in precisely the same manner. The cams G are secured upon a shaft, J, which extends the entire length of the frame, and has a. drive-pullcy secured to one end thereof.

I are other bars stationarily secured opposite the bars D. They are provided with rounding rests b, so arranged that when the sliding bars D are in the position shown in Fig. 4 the rests a b are in proper juxtaposition to clamp a stick firmly between them, the springs I-I being free to operate with their tension.

-K are levers, two or more of which are placed in such positions that when they are actuated by the cams L on the shaft J their free ends will knock the sticks off the rests a, as shown in Fig. 5.

M is a saw-arbor secu red in suitable bearings upon a frame, N, which swings on a vertical pivot-pin, c, upon a suitable bedplate.

The operation of swinging the saw-frame is for the purpose of approaching the saw O toward the buttsendot' a stick whenever a stick is presented for operation, as hereinafter de scribed.

The devices for swinging the sawfraine at the proper intervals may be arranged in any convenient man ner-snch as shown in the drawings-wherein arcani, I?, on the shaft J, actuated, in connection with a spring, Q, a bellcrank lever, R, which latter is pivotally connected with the lever S and oscillates on the pivot c. said motion beingparticipated in by the saw-frame by reason of its engagement with the oscillating lever S at d.

The saw-arbor has a suitable pnlley,to which motion is given by a belt from an overhead shaft, so that the swinging of the saw-frame will not affect the tightness of the belt.

The saw O is dished so as to out a kerf of such nature into the stick that if the end ofV the broom-wire is inserted it will hold fast; but as this saw-kerf is not universally used for such purpose I make suitable provision to use, if desired, instead of the saw a boring attachment, which makes a small hole through the butt-end of the stick for fastening the end of the broom-wire. This boring attachment may be arranged as shown in Fig. 8, wherein S is a mandrel carrying a suitable bit and revolving in a sliding frame, which, by means of suitable intermediate connection with the cam G, such as shown hereinafter' for the mandrel T, is projected toward the butt of the stick and withdrawn when the hole is bored.

The opposite end of the machine is provided with a revolving` mandrel, T, which carries a cuttcrhead, Il, with suitable knives ar` ranged to round off or pare the end of the stick which is presented to it. This mandrel is revolved by a belt from an overhead shaft, and it is journaled in a frame, Y, which slides on the bed-plate.

The sliding of the frame Y and its mandrel from and toward its work at the proper intervals of time is produced by a cam, V, on the shaft J. This cam, in connection with the spring XV, actuates the bell-crank Z, which, as Shown in Fig. 6, in turn actuales the frame Y.

It will be seen from the foregoing description that all the operative parts are controlled in their action by cams secured on the shaft J, and these cams are so arranged as to operate the machine in the following manner: The cams G control the feed by retracting the sl iding bars l) and permitting` the feeding down of the sticks in the well onto the rests a. The springs H, in projecting the sliding bars again, force the latter to carry out the lowest stick from underneath, and to carry it forward and clamp it between the rests a Z). Vhile the stick is thus held the cams P and V perform their action, the former swinging the saw-frame (or projecting the boring attachment) toward the butt of the stick, and the latter projecting the mandrel which carries the rounding-off cutter-head, these parts, after this operation, being retracted again by springs actingin connection with these cams. Now, the cams G operate again to retract the sliding plates, but before this movement is finished the cams L actuate the knockers K to throw the finished stick off the bearings a, thus permitting the sliding plates to withdraw empty and project with a new stick again. The endwise displacement of the sticks while being operated upon by the rounding-off cutter-head, is prevented by an end plate, X.

The operation of the machine is perfectly automatic, and permits of being run with a considerable speed, finishing a stick at every revolution of the shaft J.

Vhat I claim as my invention is- I. A machine for the purpose described and having the following characteristics: a feedrack from which the sticks are fed seriatum by gravity, sliding bars under the feed-rack provided with depressed rests, onto which the lowest stick is dropped, stationary bars arf ranged adjacent to and beneath the discharge end of said rack and constructed'to act in connection with the sliding bars to clamp each stick, a saw or boring-tool at one end of the machine and constructed to be thrown into and out of contact with each' stick, a sliding mandrel at the opposite end of the machine and provided-With a cutter-head for rounding the head of each stick, and an extractor dcvice for removing each stick after it is operated on, all arranged to operate substantially in the manner described.
