SPECIFICATION forming part of LettersP'atent No. 558,177, dated April 14, 1896.

Application filed December 30,1895. Serial No. 573,772. (No model.)

To all whom t may concern:

Be it known that I, JOHN HUGHES, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in CorkShaving Machines', of which the following is a full, clear, and exact description.

My invention relates to that class of machines employed in cutting or shaving rough pieces of cork bark into stopples of uniform size and shape for bottles, jugs, dac.; and it consists of the parts and combination of parts hereinafter fully described and especially claimed.

The object of my invention is to provide an inexpensive, simple, and durable machine of the class designated above which forms the stopples with great rapidity and absolute uniformity.

My machine is automatic in action and will produce stopples of various sizes by simply moving the knife.

That my invention may be seen and fully understood by those skilled in the art, reference will be had to the following specification and annexed'drawings, forming a part thereof, in which* Figure 1 is a front elevation of my machine; Fig. 2, a plan view of the same 5 Fig. 3, an end elevation and partial section on lines Fig.

1; and Fig. 4, a transverse vertical section on lines y y, Fig. 1. i

Similar figures of reference designate like parts in the drawings and specification.

The bed 1 is supported by the legs 2, and the main driving-shaft 3 of the machine is journaled to suitable bearings carried by said legs. The pulley 4, fast to one end of the shaft 3, is driven by a belt (not shown) and in turn revolves said shaft. The pulleys 5 and 6 are fast on the shaft 3 between the legs 2. The brackets 7, 8, and 9 are bolted to the top of the bed 1 and afford bearings for the shafts 10 and 11.. The bracket 8 extends entirely across the top of the bed 1. Fast to the shaft 10, between the brackets 7 and 8, is the pulley 12, connected with the pulley 5 by the belt 13. The friction-wheel 14 is fast on the shaft 10 outside of the bracket 8. The shaft 10 also carries the pinion 15, keyed or otherwise attached thereto, between the pulley 12 and the bracket 8. The stud 16 is bolted to the bracket S and extends to the left to receive the loose gear I17, meshing with the pinion 15. The cam 18 is rigidly attached to the right side of the gear 17 and has the same center as said gear.

Tight to the free terminal of the shaft 11 is the toothed wheel 19, embraced by the split arm 20, working loosely on said shaft. The pawl 21 hooks over the wheel 19 to engage the teeth thereof and is pivoted to the arm 20. The post 22 projects from the left face of the gear 17 and is connected to the free terminal of the arm 20 by the rod 23. The ratchet mechanism above described causes the shaft 11 to describe one-eighth of a revolution every time the gear 17 rotates, or the distance between two adjacent teeth on the wheel 19, there being eight such teeth. j

The annular racks 24 24a are spaced and keyed or otherwise rigidly secured to the shaft 11 between the brackets 8 and 9. The racks 24 24:L have perforations near their peripheries to receive the eight spindles 25. The spindles 25 are capable of both a rotary and lateral movement in relation to the racks 24 24a. Each spindle 25 is provided on the end outside of the rack 24 with the small frictionwheel 26, tight on said spindle, and on the end outside of the rack 24a with the chuck 27. The chucks 27 have sharp spurs on their faces with which to hold the cork. Opposite each chuck 27 is the center 28, attached to the adjacent face of the disk 24h, which is also fast on the shaft 11, inside of the bracket 9.

The spindles 25 have the rigid collars 29, located about midway between the racks 24 and 24a, and the spiral springs 30 bear against adjacent sides of the rack 24 and said collars, thereby normally forcing said spindles forward as far as the Wheels 26 will permit. The small wheels 26 are located back of and adapted to be brought into contact with the large wheel 14, one after the other, through the medium of the ratchet mechanism before described, and rapidly revolved during the continuation of such contact.

The shaft 31 has its bearings in the bracket 8 and the box 32 at the rear of the machine. The arm 33 is rigidly connected to the terminal of the shaft 31 outside of the bracket 8,

while the arms 34 34 are fixed on said shaft` IOO between its bearings. The arms 34 are spaced and their forward ends connected by the rod 35, the outer ends of which engage the notches 36 in the peripheries of the racks 24 24. The arm 33 has the roll 37 on its forward end and is held in a somewhat elevated position by the spring 38, with said roll bearing against the under side of the cam 18. The spring 33 is pinned to the outside face of the bracket 8. As the cam 18 revolves the arm 33 is alternately depressed and elevated, and by rocking the shaft 31 causes the rod 35 to be freed from one pair of notches 36 and engage the next pair. The parts just described constitute the latch mechanism.

The feed-rest 39 is attached to the rear of the bed 1 and serves as a guide over which the rough pieces of cork pass before being seized between the rear chuck 27 and the center 28. The rearwardly-convex finger 40 is bolted to the rear of the bed l to the right of the collars 29 and has a beveled face contiguous with a part of said collars at all times, said face being beveled from below upward to the left. The office of the linger 40 is to drive the spindles 25 to the left against the resiliency of the springs 30, when the collars 29 encounter said finger, for the purpose of causing the chuck 27 next below the rear chuck to drop a finished stopple and said rear chuck to receive a rough piece of cork.

The bearings 41 4l depend from opposite sides of the bed 1 to carry the shaft 42, on which the pulley 43 and the circular knife 44 is secured. The belt 45 connects the pulley 43 With the pulley 6. The knife 44 may be adjusted forward or backward on the shaft 42 to increase or decrease the size of stopple which it is desired to produce. The shaft 42 and the knife 44 are journaled so as to bring the latter at an angle with the front of the bed 1 instead of parallel therewith, in order to give the necessary taper to the stopples. The knife 44 operates through an opening in the corresponding side of the bed 1 and has the shield 44n over it.

After the feed-rest 39 has been filled with rough pieces of cork, one behind the other, and the shaft 3 with its coacting parts set in motion, the complete operation of my machine is as follows: As the gear 17 revolves, the ratchet mechanism turns the shaft 11 with attached members, the latch mechanism operated by the cam 18 alternately releasing and engaging the racks 24 24, all as hereinbefore described, and the finger 40 causes the rear spindle-chuck 27 to open and close upon one piece of rough cork after another as they are pushed forward in the rest 39. The rough cork held between each rear chuck 27 and center 28is carried over to the rapidly-revolving knife 44, at which point it is itself rotated at a high rate of speed by the frictionwheels 14 and 2G. While the pawl 21 engages another tooth on the wheel 19 the piece of cork in contact with the knife 44 is shaved into a finished article. The nished stopple is held by the engaging-chuck 27 until the finger 40 is reached, when said stopple is released, and after one-eighth of a revolution of the shaft 11 a rough piece occupies the place of the former. Vhile the rear chuck 27 is seizing a piece of rough material the front chuck is assisting at the completion of a finished piece, the then upper chucks have unfinished pieces in their grasp, two of the lower chucks have finished pieces in their grasp, and the chuck next below the rear one has just dropped its piece. As the front spindle 25 passes below the center, its wheel 26 clears the wheel 14 and said spindle ceases to revolve and the wheel of the next spindle comes in contact with said wheel 14. Thus but a single spindle revolves at any one time.

More or less than eight spindles 25 may be employed in my machine by changing the ratchet-and-latch mechanism to correspond.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-
