IMPROVEMENT IN MACHINES FOR FINISHING DRAIN-TILES.

Specification forming part of Letters Patent No. 126,929, dated May 21, 1872.

Specification describing anew and Improved Drain-Tile Jointer, invented by ANDREW L. BROWN, of London, in the county of Madison and State of Ohio.

Figure 1, Sheet 1, is a side view of my improved machine. Fig. 2, Sheet 2, is a detail sectional view of the same taken through the line a: 00, Fig. 1. Fig. 3, Sheet 2, is a detail longitudinal section of a couple of tiles illustratin g the joint.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved machine for beveling one end and recessing the other end of lengths of draintiles to form gt joint, and which shall be simple in construction, convenient in use, and effective in operation; and it consists in the construction and combination of various parts of the machine, as hereinafter more fully described.

A represents the frame-work of the machine. B is the driving-shaft, which is hung in bearings attached to the lower part of the frame A, and to one of its ends is attached a pulley to receive the belt by which motion is communicated to said shaft. To the shaft B, near each end, is attached apulley, D. E are bands, which pass around the large pulley l) and around the small pulleys F, which are placed upon the short shafts G, with which they are connected by a tongue and groove, a slot and 'pin, or other device which will allow the shafts G to be moved longitudinally through the pulleys F while being carried around by and with said pulleys .in their revolution. The shafts G revolve in bearings in the brackets H attached to the upper part ofthe frame A, and against which brackets the hubs or sides of the pulleys F rest to keep them in place. To the outer ends of the hubs of the pulleys D, or to the shaft B at the outer sides of said pulleys, are attached, or upon them are formed, flanges'or wheels I, upon the edge of which rests the forked lower ends of the levers J, the said flanges or wheels being made with an outwardly-projecting offset or cam, as shown in Fig. 1, to give an outwardmovement to the lower ends of the said levers J at the proper time. The levers J are pivoted at their middle part to the frame A, and their upper ends are forked to ride in a groove around the outer ends of the short shafts G, so that the said shafts may be moved out and in automatically by the movement of the levers J. K is an arm, which passes through the inner end of one of the shafts G, at right angles to said shaft, and is adjustably secured in place by a set-screw, wedge-key, or other convenient fastening. The upper end of the pin K is bent inward at right angles, as shown in Fig. 1; L

is a wire, one end of which is attached to the end of the arm or rod K, and its other end is is attached to the body of said pin in such a position as to give the desired bevel to the outer edge-of one end of a length of draintile, as indicated in Fig. 1. To the other shaft Gr, near its inner end, is attached a straight arm, M, to which is attached one end of a wire, N, the other end of which is attached to a short arm, 0, attached to the inner end of the shaft ,G. The wire N is arranged at such an inclination as will give the desired bevel to the inner edge of the other end of the tile-lengths or sections. The wiresL N, when adjusted, should be exactly parallel with each other, so that the adjacent ends of the lengths or sections may fit each other accurately and form a close joint. The tile, while being operated upon, is supported and held by-a holder or carrier, P, which receives the tile from the table Q attached to one side of the top of the frame A, and delivers it upon the table R attached to the other side of the frame A. The table Q should be a little higher and the table R a little lower than the carrier 1?, so that the tile can be conveniently rolled from the table Q into the carrier P, and from the said carrier P to the said table R. The carrier P is attached to a bed-plate, S, the ends of which, or

lugs formed upon said ends, are pivoted to a rod, T, the ends of which are attached to the upper ends of the side bars of a frame, U. To the side bars of the frame U are attached keepers V to receive the bars W, and which are adj ustably secured to said bars W by setscrews X, as shown in Fig. 1. The bars W are rigidly attached to the frame A, and serve as supports and ways for the frame U. This construction allows the carrier to be turned to the table Q to receive the tile, and to the table R to discharge it. The table Q is made with a flange, Y, at one end, to serve as a guide in adjusting the tiles. The carrier 1? should be detachable, so that it may be detached from the carrier S and replaced with one of a differentsize to correspond with the size of the tiles to be operated upon, the frame U being adjusted upon the bars W accordingly. To the middle part of the bed-plate S, near one side, is pivoted the upper end of the connectingrod Z, which is made in two parts, sliding upon each other, and secured by a set-screw, so that it may be conveniently adjusted in length, according to the adjustment of the frame U. To the lower end of the adjustable connectingrod Z is attached a pin, A, which passes through a guide slot or groove, B, in a grooved wheel, 0, attached to the shaft B, so that the carrier P may be moved automatically to the table Q to receive the tile, may be moved beneath the shafts G and held while its ends are being operated upon, moved to the table R to discharge the tile, and again moved back to the table Q, to receive another tile. 1) is a bar, one end of which is attached to the lower end of the connecting-rod Z or to the pin A, and its other end is attached to the frame A. The bar D is designed to assist the slotted or grooved wheel B 0 in controlling the movements of the carrier .P. One of the belts E may be crossed, and t he other straight, to revolve'the cutters in opposi tedirections, so that they may tend to hold the tile while being operated upon securely in place.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination of the pulleys D, bands E, pulleys 1?, shafts G, cam or guide wheels I, and pivoted levers J with the driving-shaft B and cutters K L M N O, substantially as herein shown and described, and for the purpose set forth.

2. The pivoted carrier P, in combination with the receiving and discharging tables Q R and cutters K L M N O, substantially as herein shown and described, and for the purpose set forth.

3. The combination of the adjustable frame U, stationary supporting-bars W, adjustable connecting-rod Z, pin A, grooved or slotted cam-wheel B G, and arm D, with the driving-shaft B and pivoted carrier P, substantially as herein shown and described, and for the purpose set forth.
