BURNISHINGC-MACHINE.
SPECIFICATION formingpart of Letters Patent No. 235,921, dated December LZS, 1880. Application filed April 17, 1880. (N0 model.)
To all whom it may concern Beitknown that 1, WM. 0.WAY, ofBuckland, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Burnishin'g Machinery, of which the following is a specification, reference being had to the accompanying drawings, where- Figure 1 is atop view. Fig.2 is a side view. Fig. 3 is a front view. Fig. at is a detail view of a burnishing-bed. Fig. 5 is a view, in vertical transverse section, on plane m .r, Fig. 1.
The letter a denotes the table bearing the main part of the mechanism supported on suitable legs or standards. At the rear thereof,
hung in suitable bearings, is the main shaft 1), to which power and rotation may be applied by a belt running on pulley c. This shaft bears loose thereon the crank-disk d, which may be made to rotatewith the shaft, by means of the friction-clutch 6, fast rotarily, but loose longitudinally, on the shaft, having a conical cup or opening in its side co-operating with a part cone, f, borne upon the disk and moved to en-' radially in this groove, so as to give a greater or less length of stroke to the burnisher, hereinafter described. A pitman, j, is pivoted to the pin on the crank-pin block, and is pivoted at the other end to the piston k, whereby a longitudinal reciprocating motion may be imparted to the piston.
The piston is polygonal in section, preferably square, so that it may not rotate except as the sleeve 1, within which it reciprocates, also rotates: This sleeve 1 is borne in a bearing or journal-box, m, so that it can partially rotate. 1t is desirable, in using this machine for burnishing the bowls of spoons, that this sleeve 1 should have a partial rotation as it moves up and down, (for it does move up and down,) and such rotary motion is attained by having the arm a, which is fast to a collar encircling one end of this sleeve, enter the pivot-block 0, rotarily hung in the post p, the foot of which has the slot or mortise 1', through which a setscrew, 8, runs into the table, whereby the post 19 may be adj ustably set at different distances from the sleeve to control the character of the rotary movement of the sleeve.
The front end of the piston bears, pivoted laterally thereto, a burnisher-armi, t, in the front of which is hung, so that it can rotate, a highly polished round burnisher, u, kept against the work by a spring, '22.
From the table rises a stock-bearing standard, w, havingin its inner face adovetail horizontal groove, 3 in which is a bed-plate, 2, which can be adj ustably set at different points in the groove. There is a matrix in this bedplate to receive a soft-rubber (substantially india-rubber, pure gum) bed, a, which is so shaped on the face as to substantially correspond to the shape of the piece of stock to be superimposed upon it. In the case of a spoon to be burnished on the outside of the bowl the face of the rubber bed is shaped to substantially correspond to the inside of the bowl. (See Fig. 4.)
The bed-plate bears the catch or stop b, under which the tip end of the piece of work can be caught. The piece of work is then fastened in place by means of the catch or book 0 and the cam d.
The front end of the piston also bears, pivotcd laterally therein, another burnisher-arm, e, which bears another loosely-rotating round burnisher, f, and the table bears another standard, g, with bed-plate, rubber bed, 850., all similar to the corresponding parts just described, and when spoons are being burnished there is an advantage in burnishing the outsides of the bowls on one standard and the insides of the bowls upon the other standard at the same time, and the spring presses from one burnisher-arm to the other.
will now explain how the up-and-down motion is given to the journal-boxm, and consequently to the burnishers, such movement being necessary to cause the burnishers to traversethe breadth of the work.
The letter h denotes a vertical rotating shaft driven from main shaft b through the medium of pulley i, belt j, pulley la, shaft 1, worm m, and spur-gear n. This shaft bears the left-hand thread 0 and the right-hand thread 19.
The letter 1" denotes a sliding pawl bearing at one end a nut-section, s, fitted to mesh into the thread 0. The letter t denotes another and similar sliding pawl bearing at one end a nut-section, a, fitted to mesh into the thread 10. Both these pawls are borne in and slide inthe socket-box 07'; which is fast, through the medium of an intervening arm,'v to thejournal-boXm. Only one of these pawls is thrown into mesh with its thread on the vertical shaft at the same time. When pawl r is thrown into mesh the journal-box m is thereby moved downward, and when pawl t is thrown into mesh the journal-box m is thereby moved upward. A lever, w, pivoted to the socket-box c, has pins taking into the sides of these two pawls, by the manipulation of which lever either pawl can be thrown into mesh, or both held unmeshed. This lever is provided with the stop-fingers y y, which, at appropriate times, wil. alternately strike the stop 21, and thus throw the pawl, which is then meshed, out of mesh, thereby stopping the vertical feed of the burnisbers and giving the operator notice to supply a fresh piece of work. The journal-box mis borne on a pillar or post, a, sliding in sockets,'so as to allow the pillar vertical movement.
I claim as my invention 1. A soft-rubber burnishing-bed fitted to the shape of the work. substantially as herein shown and described.
2. The combination of a reciprocating burnisher with a soft-rubber burnishing-bed, substantially as herein shown and described.
3. The combination of the work-bearing standard w, the bed-plate z, adjustable on the standard, and the rubber bed a", all substantially as herein shown and described.
4. The combination of the work-bearing standard to. the bed-plate 2, adjustable in the standard, the burnishing-bed a, the catch 1), and the hook and cam c d, all substantially as herein shown and described.
