BURNISHER.

SPECIFICATION forming part of Letters Patent N0. 436,866,dated September 23, 1890.

Application filed October '1, 1889. Serial No. 326,201. (a model.)

To all whom, it may concern:

Be it known that I, WARREN H. Bones, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Buruishers, of which the following, taken 'in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to an improved burnishing or surfacing machine of the same class referred to in my pending application, Serial No. 309,392, and has for its obj ect the production of a simple and efieetive machine at a minimum cost of operation, which will provide cards or other articles with a smooth or glossy surface; and to this end it consists, essentially, in a novel polishing-roller formed or provided with a polishing-surface and a projecting end, and having an interior cavity containing a liquid and alam p or heater for heating the said projecting end and generating, steam in the interior of the roller, whereby the same is entirely heated.

' My invention also consists in a novel jacket for protecting said roller and in a safety-gage for preventing excess of steam on the interior of the roller; and it furthermore consists in the detail construction and arrangement of parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of the specification, in which, like letters-indicating corresponding parts in all the views, Figure l is an elevation of my improved machine. Fig. 2 is an end elevation of the machine as illustrated in Fig. 1. Fig.

4 3 isa'longitudinal section of the novel polishing-roller, a portion of the end projection and its inclosing-jacket being broken out for the purpose of increasing the scale.- Fig. 4 is a sectional view illustrating the adjusting mechanism for regulating the distance between the rollers. Fig. 5 is a perspective of the detached adjuster of the adjusting mechanism, and Figs. 6 and 7 are enlarged sectional views illustrating modifications of the adjusting mechanism of the roller.

A represents the frame of the burnisher, which maybe of suitable form, size, and construction, and, as illustrated, is composed of a pair of legs A, connected together by atop tie-bar A bolted thereto by bolts a.

The polishing-roll B is journaled in the frame A and is provided with an interior cavity B',which preferably extends the whole length thereof. Asillustrated'in Figs. 1 and 3, the roller B is provided with the polishing surface band the end extension I), here illus trated as of substantially the same length.

As preferably formed, in order to increaseits cheapness, the roller B consists of a tube mounted in the legs A, having one extremity closed by-its actuating-gear O and theopposite extremity closed by the plug D. Y

The liquid is inserted into the roller B by means of suitable inlet-openings, the arrangement of which forms one of the novel features of my invention. part of the end of said roller is the central opening (1, into which opens the passage d,

Provided in the central extending to the outside of the roller and filled or closed by a screw or other suitable plug d Extending in opposite directions from the central opening at are the passages (1 which conduct the liquid from the opening (1 to the interior of the roller B. When the plug (1 is removed and the liquid is poured into the opening (1, the same descends down the lower passage (1 and forces the air from the opposite passage, which opens into the top of the cavity B. The filling then continues until thelevel of the liquid within the cavity or chamber B rises above the lower part of the upper opening (Z whereupon the outlet of the air is prevented, since the same would then necessarily be forced downward through the liquid and afterward upward through the opening (1, which now becomes filled with the liquid. It will be understood that the roller is now a little more than half full, and that the passage (1 may be closed by inserting the plug (1 Experience, however, has demonstrated that the best results are obtained by turning the roller over and allowing the outward flow of the liquid, which continues until the roller is but half or a little less than half full.

In order to prevent an excess of steam within the roller B, I provide a safety valve, which also forms a feature of my invention. Guided in the central passage d is a stem E,

having one extremity extended to the interior of the roller. Upon the opposite extremity I provide the valve e, which engages avalve-seat 8', provided at the outward extremity of the plug D. Mounted upon the inner extremity of the stem E is the nut (2 between which and the adjacent face of the plug D is interposed a suitable spring F, preferably composed of phosphor-bronze wire to prevent corroding thereof. A second or jam nut e abuts against the nut e and prevents its displacement. lVhen stem is generated within the cavity B by heating the extension I), as will be presently described, the pressure thereof forces outward the stem E and disengages the valve 6 from the seat e, whereupon the excess of steam escapes, keeping the roller at an even temperature and absolutely preventing bursting thereof. It will be understood, however, that the tension of the spring F is soregulatedthat the safety-valve will operateon-ly when a greater degree of steam-pressure is, attained than desired. By closing the opening at the liquid within the roller is heated over and over again, and there is but littlewaste thereof, excepting such as would naturally occur from friction.

Surronnding the end extension I) of the burnishing-roller B is the jacket G, having a spaceinterposed between said extension and the interior of the jacket. One extremity of the. jacket is closed by being tightly abutted againsta face or hub a upon the leg A by means of screws or bolts a engaging alug provided upon'said jacket and leg. The opposite extremity of the jacket is open to allow the exit of the heat, and is preferably of greater diameter than the inner extremity, in order toproduce abetter draft.

' lrovided in the jacket G, and preferably in the lower part thereof, is the opening G, formedwith the depending flange g, surroundin gv the extremity of a suitable lamp or heater 1. As illustrated in the drawings, this heater consists of the ordinary photographers petroleum lamp; but it will be understood that, if desired,other styles and kinds of heater could be used without materially changing the construction of the jacket G.

Theheated current produced by the lamp I encircles the end b, produces steam within the: roller, and then passes out through the open extremity g. It will be understood that, as the roller is but partly filled, and as heat is applied to but one end, a perfect circulation is produced, which evenly heats the roller throughout its entire length. An even heating is further produced by revolving the roller, causing the entire periphery thereof to be subjected to the flame of the lamp.

It will be evident that besides minor advantages my. improved burnisher-roller presents the important advantages of increased rapidity of heating, economy of manufacture, and freedom of the operator from the escaping heated current after its exitsfrom the burni'sher. Heretofore the heater or lamp for burnishers has been directly beneath the polishin g-surfacc of the same, and the operator, who is directly over the burnisher, is thus compelled to inhale the heated current therefrom, which is a feature .of great disadvantage. However, by placing the heater at one side of the polishing-surface and providing the roller with an end extension this inhalation of the gases and heat is absolutely obviated.

An additional feature of advantage is the freedom of the burnisher from sweating, since as brought forth in my hereinbefore-referred' to application when there is a heated current of steam or water on the interior of the burnishing-roller there is no liability of sweating on the exterior thereof. Moreover, by arranging the heater at the side of the burnisher the space between the legs of the f rame may be utilized for stacking cards, which is a further feature of advantage.

I also utilize to the greatest extent the amount of heat generated by the heater, since the top thereof closely fits the opening G of the jacket G and absolutely prevents the entrance of cold air within said jacket. Moreover, the circulation of the heated current around the roller when within the jacket heats the same very rapidly, and the heat is. applied to the identical point where it is desired and there is no loss from radiation. Radiation is further prevented by providing the jacket with an inclosing-case J, of asbestus or other suitable packing, which, if desired, is incased by a covering of tin or other suitable material.

As previously set forth, it will be 'understood that there is a perfect circulation within the burnishing-roller; but in order to aid this circulation I frequently deem it advisable to utilize the screw or propeller K, which is of suitable form and construction and secured within the roller so as to feed forward to the polishing-surface the heated liquid and steam from the end extension b. Any suitable means may be utilized to secure the propeller within the roller B but as the same is revolved but slowly the desired object is produced by so forming the said propeller that the same tightly fits the interior of the.

cavity 13'.

The return of the steam and water from the interior of the polished surface is allowed by forming the propeller with a central passage or tube K, having its forward extremity open to receive the said steam and water at one extremity of the roller and open at the opposite extremity to discharge the same into; the end extension 1). It will, however, be noticed that my improved burnishing roller will give very efiective results without the use of this propeller K.

Mounted above the roller B and adjacent thereto, is the feed-roller L, having its periphery provided with a suitable knurled or frictional face for readily engaging the card or other article to be burnished. Connecting these two rollers L and B is a suitable pair of 19, connected together by the tie-bar p.

gears 0, one of which is revolved byahandle M and serves to convey motion to the other.-

, In order to adjust the feed and burnishin g rollers toward and away from each other to adapt the same for different thicknesses of articles, I mount the extremities of the feedroller in suitable boxes N, sliding in ways a face'thereof.

.Interposed between the boxes N and the frame A are springs S, which are preferably mounted upon the rods n and constantly force upward the said boxes to separate the rollers B and L. As is well known, the tension of these springs frequently varies, and the screws R, which are independently adj ustable, thus allow the adj uster'to be adj usted to any differences in the tension of the springs, whereupon a jam-nut r retains the same in its adjusted position.

Provided at the end of the adjuster and at theopposite side of the center thereof to the pivotal screw R is theadjusting-screw T, by which the position of the adjuster can be varied at will. It will thus be seen that by operating the screw T the rollers L and B can be adapted to any desired thickness of card or other article.

At Fig. 6 I have shown a modified form of the adjusting device, in which the adjuster consists of a disk U, eccentrically pivoted at u to the tie-bar A Pivoted to the separate eccentrics U is the connecting-barU, having at one extremitya threaded socket to, engaging a spindle 11. having a knurled extremity 11. Depending from the tie-bar A are lugs a 0., provided with slots 0. in which said spindle a is guided. Secured to the spindle 11. is a washer or shoulder to, interposed between the separate lugs a a, and preventing the said spindle from longitudinal movement.

At Fig. 7 I have shown a further modified form of the adjusting device, in which a rod 7 is journaled in the tie-bar A and is revolved by a suitable knurled extremity w. Secured to this red is a bevel-gear w,engag in g a like bevel-gear 10 prevented from longitudinal movement by abutment with a shoulder (1 of the tie-bar A and provided with a depending screw-threaded spindle engaging a threaded socket in the box N.

It willbe understoodthat, if desired, asstated in my previous application, Serial No. 309,392,

As best illustrated in Figs. 4 and 5,-

the roller L might be provided with a yielding face, which would adapt the same for polishing or surfacing articles of varying thickness, as laundry, leather, X50.

The operation of my invention will be readily perceived from the foregoing, and it will be understood that the same is very cheaply constructed, efficient in operation, and presents many desirable features of advantage. It will also be understood that considerable change may be made in the detail construction and arrangement of the parts without departing from the spirit of my invention. Hence I do not limit myself to its precise form and construction.
