PAOLI GOKE AND' GILBERT KEMPER, OF CINCINNATI, OHIO., 'ASSIGNORS TO THE CINCINNATI COFFIN COMPANY, 0F CINCINNATI, OHIO, A CORPORATION OF OHIO.
DEVICE FOR BURNISHING METALLIC ARTICLES.
Application led April 3,
To all whom t may concern.'
Be it known that we, PAUL J. Golia and GILBERT L. KEMPER, citizens of the Unitedl States of America, and residents of Cincinnati, in the county of Hamilton. and State of Ohio, have invented a new and useful Improvement in a Device'for Burnishing Metallic Articles, of which the following is a speciiication.
An object of our invention is to provide asimple and efficient device for burnishing metallic articles.
Another object of our invention is to provide a device which is positive in operation, and in which injury to the articles during the burnishing thereof is precluded.
Another object of our invention is to provide a device into which and from which the arti-cles that are to be burnished may be readily inserted and removed.
These and other objects are obtained by means described herein and disclosed. in the accompanying drawing, in which:
Fig. 1 is a plan vview of a device embodying our invention.
F ig. 2 is a fragmental perspective View of a drum and the interior thereof, forming a detail of our invention.
Fig. 3 is an enlarged sectional view on line 3-'3 of Fig. 1. y
Fig. 4'is an enlarged plan view of a rack forming a detail of our invention.
Our invention comprises a tank 5, on the end walls 6 and 7 of which is revolubly mounted a shaft 8.- The shaft extends through the wallv and carries a pulley 9 where ythe shaft maybe revolubly actuated. A drum 10 is mounted on the shaft and is adapted to revolve therewith. Interiorly to the drum, there is mounted on the shaft, a rack holder 11. `The rack holder is revolubly mounted on the shaft, any suitable means being' employed for this such as by loosely mounting the/sleeve 12,011 the shaft, and the sleeve having mounted on it the rack holder structure. The tank 5 is adapted to contain a cleansing fluid 13, and the drum 10 is so constructed that this fluid 'may-A enter into the drum, although the shot, 14 contained within the drum cannot escape-therefrom. The drum comprises the ends 15 and 16 between which extend a series of panels 17 one of which panels 1s removably mounte on the ends 15 and 16 and serves as a door whereby access may be 1922.

had to the interior of the drum. The rack holder comprises ends 18 and 19 upon the inner walls of which are mounted the rack supports 20. Theends 18 and 19 of the rack holder are secured to the sleeve 12. rIhe ends ofthe drum, and the ends of the rack holder carry lugs 21 and 22 respectively,
joined at their ends by cross bars 26 and 27,
the cross bars having eyes 28 and 29 through which the bolts 23 may extend. When the racks are mounted upon the supports, any suitable means such as the nuts 30, maybe employed to secure the racks to the support. If desired, wing nuts may beused. A number of pegs 31 are mounted on the plates 24 and 25, and are adapted to extend through the apertures 32 formed in articles 33, which articles are to be polished or'. burnished. A bar or rod 34 extends through the aligned eyes 35 formed in the pegs, and precludes separation oflthe arti-- cles from the peg. The pegs are naturally varied in form so as to accommodate various types and kinds of articles.,
In the operation of our device a Huid 13 elements such as shot 14 are placed inside the drum. The drum may be revolved so as to bring the removable panel 17 to its uppermost position, in order to facilitateV the insertion of the shot l4`in the drum. It is also possible, when the opening'of the drum is uppermost, to insert the racks in the drum, and to mount the racks upon-the rack holder. The racks are mounted one at a time, and as soon as any one rack has been secured upon the rack holder, the holder may be revolubly actuated so as to is run into the tank 5, and suitable cleansing bring the next pair of rack supports to their uppermost position to facilitate mounting of the next rack upon the holder. After the racks are mounted on the rack4 holder, the removable panel is secured upon the drum. Rotatory motion is then imparted to the shaft 8 by means of the pulley 9.
e@ on the shaftA adapted to contain cleansinle;l
The drum, being fixed securely upon the Shaft, revolves with the shaft, and when the lug 21 on the drum engages the lug on the rack holder, the rack holder revolves with the drum and the Shaft. The shot being heavy, is rolled from panel to panel of the drum, thereby coming into repeated contact with the articles carried by the racks. The articles on the racks' are also moved through the mass of shot, as is readily apparent by reference to Fig. 3. This action of the shot on the articles, and of the racks through the shot, together with the cooperation of the cleansing fluid, burnish and polish the articles carried by the racks, Without lnarring or scratching such articles. `What We claim is:
l. ln a device of the class described the combination of a tank adapted to contain a cleansing fluid, a porous drum revolubly mounted in the tank adapted to extend into the fluid and to contain cleansing elements, and a holder revolubly contained Within the drum adapted to support articles, and means to revolve the drum and holder.
2. In a device of the class described the combination of a tank adapted to contain a cleansing fluid, a revoluble shaft mounted on the tank, a hollow drum mounted fiXedly aneageaa elements and into and from which the lluid may How, a rack holder contained within the drum revolubly mounted on the shaft, racks mounted on the holder adapted to carry articles thru the cleansing elements and fluid, and cooperatin lugs extending from the drum and the ho der, the lugs being adapted to engage one another whereby motion may be transmitted from the drum to the holder, and to permit limited independent movement of the drum and holder.
3. ln a' device of the class described the combination of a tank adapted to containy a cleansing fluid, a hollow drum revolubly mounted in the tank and having a removable anel whereby access to the inter-iol of the rum may be had, a rack holder revolubly contained Within and adapted to rcvolve with the drum, and racks removably mounted on the rack holder adapted to be mounted on the holder and to be removed from the drum thru the o ning provided in the drum by removal o' the referred to panel.
In testimony whereof, We have hereunto subscribed our names this 31st day of March, 1922;V
