A pplicaiion filed December 9, 1881.
(N model.)
To aZZ whom it may concern.- 7
Be it known that I, ISAAC VAN IIAGEN, a citizen of the United States, residing in the city of Chicago, in the county of Cook, in the State of Illinois, have invented certain new and useful Improvementsin Machines for Govering Stove-Boards, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my improved machine. Fig. 2 is an edge elevation of the finishing-tool. Fig. 3 is an enlarged longitudinal section of the chuck, which forms part of the machine. Fig. dis an enlarged front elevation of the shieldfacing and the retainer in which it is set. Fig. 5 is an enlarged rear elevation of the shield alone. Fig. 6 is an enlarged longitudinal section of the retainer with the shield set in it. Fig. 7 is a similar section of the chuck with the stove-board and cover set in it, and the shield resting in the retainer and set close against the board. Fig. 8 is an enlarged rear elevation of the shield, the plates of which it is made up being separated from each other. Fig. 9 is a plan view of part of a circular metal cover for a stove-board with a c-rimped boarder.
The same letters denote the same parts in all the figures.
My invention relates to appliances for placin g sheet-metal covers on stove-boards or platforms, so that the edge of the cover shall be turned under the board, and has more particular reference to circular platforms and covers, and to covers of crystallized tin or other hard metal. The wooden platforms'in general use vary in thickness from half to seveneighths of an inch, and the metal top has to be bent on the margin so as to cover the 0 edge of the board and extend under it for about three-eighths of aninch, which requires a turned edge of a total breadth ranging from three-quarters of an inch to an inch and an eighth. Such an edge of hard metal cannot be turned on an unprotected wood platform without breaking the wood.
The object of my invention is to provide for turning the requisite edge of hard metal as readily and with as little damage to the wood as an edge of zinc; and it consists in certain special features in the construction and arrangement of apparatus for this purpose, and combinations of devices which will be fully described hereinafter, and definitely pointed out in the claim.
In the drawings, A denotes the chuck, in which the board and cover are set during the process of turning the edge of the cover under the board. It is a dished disk of suitable area and depth to contain the board and cover. Its rim a flares outwardlyto correspond with the slope in the edge of the board B. The chuck is rigidly set on the forward end of a revolving shaft, 0, which is mounted 011. the frame D, and turned by a band passing over one or other of the wheels 0, C and 0", according as a greater or less degree of speed is required; The retainer E, which forms a frame or support for the shield, is set parallel with the chuck on the nearer end of a shaft, F, whose axis is in the same line with that of O. The shaft F is mounted in the frame G, so as to be capable of a longitudinal motion. The retainer is in form a wheelhaving the spokes or arms 0 and the broad felly c, on which the 7 5 shield is set. This'felly has in its outer face a circular groove, 6 The diameter of the retainer issomewhat less than the inside diameter of the chuck A, the difference being about twice the breadth of the metal edge which is to be turned under the stove-board. The shield or facing II rests against the front of the retainer and extends beyond its circumference not quite far enough to touch the inner margin of the rim a of the chuck when brought up to it by the forward motion of the retainer, the intervening space being reserved for the metal cover J. The shield is made in three or more separate plates, so as to be readily adjustable in its place on the retainer and readily de- 0 tachable therefrom.
In the particular construction shown in the drawings there are four plates, made in pairs, the two larger, H, being formed by cutting off from the outer circumference of 11 two oppo- 5 site and equal arcs of about one hundred and thirty degrees each, each are being out off not by a single chord, but by two secants, each diverging very slightly from the chord of the arc toward the circumference of the circle. Each sec'ant intersecting theinner circumference of H also, the two smaller pieces, H are sepa rated by the same operation, each containing about fifty degrees of the outer circumference. Any one of these pieces being set in the retainer, all the others readily arrange themselves in corresponding places, if only care be tak en to put in next an adjacent and then an opposite part, the difference of shapes making it ohvious at a glance which is which. The shield H is flat on the outer surface. A circular ridge, h, on its inner surface fits snugly into the groove 0 of the retainer. That part h of the inner surface which is beyond the outer circumference of the retainer tapers uniformly all around to a thin edge.
In operation, the margin j of the metal cover is first crimped or corrugated to the desired breadth and turned at an angle to the rest of the cover corresponding to the inclination of the edge of the board, as shown partly by full and partly by dotted lines in Fig. 7.
In an application for patent filed atthe same time with this I have shown means for performing this preliminary operation on acireular cover. The cover, its edge having been bent so as to contain the board, is placed in the receiver and the board B is set within it. The shield Hbeing set in its places on the retainer, the latter is slowly driven forward by the application of power to the farther end of its shaft F,pressing the board uniformly on its whole surface and thus fitting it into the cover J. The part 9' of the bent edge of the cover which projects beyond the edge of the board is then bent down by any convenient means (preferably by the finishing-tool hereinafter described) on the chamfered part h of the shield, as shown by full lines in Fig. 7, the shield protecting the edge as well as the back of the board from being cut or bruised by the metal cover. The shield also operates to press to a uniform level the peripheral strips of wood which mainly constitute the bottom of the board, and thus to level the entire boardan important result, inasmuch as it is almost impossible to put together the several pieces of which a stove-board is usually constructed so that there shall not be more or less difference of level between them. The retainer E is then withdrawn by means of its shaft F, the shield H being at the same time held so that it shall not be drawn away. The retainer being drawn back the shield is taken off, which is easily done by beginning with one of the smaller pieces, H, the part j of the crimped margin being left at a small angle with the bottom or outside of the boardB. The finishing-tool, (shown in Fig.2,) consisting of atoothed wheel, K, revolving on the end of a handle, L, the toothed edge corresponding in conformation to the corrugations on the margin of the metal cover, is then pressed steadily against the part j of the margin, while the chuck A is madeto revolve by connecting one or other of the wheels 0, G", and O with the driving machinery. The margin j is thus accurately fitted to the bottom of the board without any cutting or bruising of the board. When thus finished, the board may be pushed out of the chuck by means of the holes a in the back of the latter.
