IMPROVEMENT IN B UJRNISHING-MACHINES.
I Specification forming part of Letters Patent No. 199,592, dated January 22, 1878 application filed lo all whom it may concern Be it known that I, JEREMIAH STEVER, of
Birmingham, in the county of New Haven and State of Connecticut, have invented certain of the invention, such as will enable others skilled in the art to which it pertains to make j and use it, reference being had to the accompanying drawings, which form part of this specification. My lnvention relates to an improvement in burnlshmg-machines.
burnishing-machine of such a construction that a number of articles may be burnished on a single machine at the same time, and the work accomplished in an accurate and ready manner;' and to that end my invention consists of, first, in a burnishing-machine, a movable plate or table adapted to have any desired patterns secured thereto, in combination with a yield-' ing follower, and a series of burnishing-tools,
said follower and burnishers being secured to a superposed plate adapted and arranged to have a movement at right angles to the pattern-plate, whereby all of said burnishers are yielding plate furnished with one or more yielding followers, and a series of burnishers attached toyielding stocks or holders, whereby the weight of the burnishers is upheld by the springs, and consequent wear saved the follower and patterns.
My invention further consists in the several details of construction and combinations of parts, as will morefully appear from the fol lowing description and claims.
In the accompanying drawings, Figure 1 is a view, in perspective, of my improved burnish- December 8, 1 877.
ing-m'achine. Fig. 2 is a front elevation, and Fig. 3 an end view, of the same' Fig. 4. is a detached view of one of the burnisher-holders,
and Fig. 5 is a modification. i A represents the bed-plate of the machine, the same being supported by the legs a, which latter maybe rigidly secured to the floor or bench. B is a plate adapted to have a free horizontal movement in the guideways b, the
latter being secured to the bed-plate A.
Areciprocatingmovementisimparted toplate B as follows: To the bed-plate A are attached the bearings a 00 within which rest the ends of the screw-threaded shaft 0, the outer end The object of this invention is to provide a of which carries a band-wheel, c. To the under side of the plate B is secured a nut, a, which is screw-threaded to receive the threads of the shaft 0.-
By turning the shaft 0 in one direction the plate B is moved in one direction, and, by reversing the revolution of said shaft the plate is moved in the opposite direction. This movement may be impart-ed in an automatic manner, if desired, by attaching suitable clutches, pulleys, and belt shifters to the drivingshaft D or fast and loose pulleys may be secured to said shaft, and the movement of the plate controlled by an ordinary belt-shipperarranged to be controlled by the workman. To the opposite ends of bed-plate A are secured the standards E, which serve to sup-v port the transverse guideways E. Within grooves 0, formed in the inner edges of guideways E, are placed the ends of a transverselyreciprocating plate, F.
Plate F is moved as follows: Two or more arms, f, are secured at their lower ends to ter-shaft f is revolved, a reciprocating moveone of the burnishers.
' sired to burnish but a small surface of an article, the plate carrying the burnishers is moved in such position that the followers will rest upon the central portion of the patterns. The ends of the connecting-rods are then secured to the wrist-pins, which latter are attached to the disks at a sufficient distance from their centers to insure the desired stroke of the plate, so that every portion of the article required to be burnished shall be traversed by the burnishers.
H is a yielding plate or burnisher-carrier. It is hinged or pivoted at its rear side to the plate F at h, and is upheld from the plate F .by means of spiral, volute, or other springs, h which are placed between said plates at their forward edges. The power exerted by the springs h in forcing the plate H away from the plateFis counteracted by the springs 71?, which latter are coiled about short shafts h attached to the imder side of plate F. The forward ends of springs h are attached to the front edge of the yielding plate H. This arrangement of parts operates to impart an upward and downward yielding pressure to the plate H, for apurpose hereinafter set forth. I represents burnisher-holders, and the same are formed with open side grooves 41, for the reception of the burnishers, which latter are removably secured by setscrews 6. Burnisher-holders I are provided with arms J, located at, right angles to the stocks. Arms J are each pivoted between two plates, j, secured to the upper surface of the yielding plate H. A downward yielding pressure is imparted to the burnishers and followers by means of the springs K, which are placed within sockets L, secured to the arms J.
The tension of the springs K may be regulated by means of the adjusting-screws l, inserted in the upper ends of sockets L.
The operation of myimproved burnishingmachine is as follows: Any desired patterns, M, (the counterpart of the articles to be burnished,) are secured to the table B at either end thereof, and the followers are then adjusted in such position that they will press upon said patterns. The articles to be burnished are then secured in any desired manner to the plate B, each of said articles being located immediately beneath and inline with Motion is then imparted to the driving-shaft, which, in turn, imparts a reciprocating movement to the plate H, through the medium of the connecting-rods.
The burnishers are thus reciprocated the entire length of the articles being operated upon and the articles are moved at right angles to the movement of the burnishers by means of the screw-shaft, which actuates the plate to which the articles are secured. The pressure of the followers upon the patterns is regulated, independently of the combined weight of the burnishers, by means of the springs, which serve to support the yielding plate to which the followers and burnishers are secured. This arrangement of parts admits of any desired pressure of the followers upon their respective patterns. The pressure of the burnishers may be readily regulated by adjusting the screws, which serve to vary the tension of the springs, located in the several sockets attached to the burnisher-arms. As the plate to which the articles are attached has a movement at a right angle to the movement of the burnishers, and as the latter are reciprocated the entire length of the articles operated upon, it follows that every portion of the surface of the said articles is subjected to the action of the burnishers.
The particular shape or size of the article to be operated upon is immaterial as regards'the operation of the machine. In every case the followers travel over the entire surface of the patterns, and transmit most accurately and perfectly the contour of said. patterns to the burnishers, so that the latter will exert a predetermined pressure on the surface of the articles irrespective of their shape and size.
It is obvious that many advantages will fol'-' low the use of a machine embodying my invention, as a number 'of articles may be burnished simultaneously on a single machine, and each article is subjected to the same pressure and action of the burnishers, thus insuring a uniformity of finished work not possible to be obtained by the ordinary method of hand burnishing.
' It is evident that many slight changes maybe made in the details of construction and an rangement of parts without departing from the spirit of my invention, and hence I do not limit myself to the exact construction shown and described; but
What I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with a movable plate adapted to have one or more patterns and a number of articles to be burnished secured thereto, of a superposed movable plate provided with one or more followersand a number of burnishers, substantially as set forth.
2. The combination, with a movable plate'or table adapted to have one or more patterns and one or more articles to be burnished secured thereto, of a superposed yielding plate provided with one or more followers and one or more burnishers, said yielding plate arranged and adapted to be moved transversely to the movement of the pattern-plate, substantially as set forth.
3. The combination, with a reciprocating plate and a plate hinged thereto, said plates being connected'to each other in a yielding manner, of one or more followers and one or more burnishers, substantially as set forth.
4. The combination, with a reciprocating plate and a yielding plate hinged thereto, of one or more followers and a series of burnishers, said followers and burnishers being removably secured to independent and yielding holders, substantially as set forth.
5. The combination, with the yielding plate, of a series of burnisher-holders, the same provided with sockets and springs, adapted to have their tension adjusted by screws attached to said sockets, substantially as set forth.
6. The combination, with a series of burnishers and one or more followers, said burnishers and followers attached to a yielding plate, of a pattern-plate provided with a screw-threaded nut and a screw-threaded shaft, adapted to engage in said nut and impart a reciprocating movement to said plate, substantially as set forth.
7 .y The combination, with the longitudin allyreciprocatingpattern-plate B, the transverselyreciprocating plate F, and hinged plate H, of the springs h h and the series of burnishers, substantially as set forth.
8. The burnishenholders J, constructed with an open groove, 43, at one end, and provided with a socket, L, at the opposite end, substantially as set forth.
9. The combination, withv the yielding plate H, of one or more burnisher-holders, pivoted to said plate, and springs K, located in sockets L, formed on one end of said holders, substantially'as set forth.
10. The combination, with the plate F and hinged plate H, the latter provided with one or more followers and a series of burnishers, of the shaft f disks or wheels G, and connecting-rods G, substantially as set forth.-
In testimony that I claim the foregoing I have hereunto set my hand this 30th day of November, 1877.
JEREMIAH STEVER.
