To all whom it may concern:

Be it known that I, GAYLORD W. MARTIN, a citizen of the United States, residing at Fort Scott, in the county of Bourbon and State of Kansas, have invented certain new and useful Improvements in Large Ware J ollie Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in jollie-machines, or machines for turning earthenware vessels; and its novelty and advan tages will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which Figure 1 is an elevation of my improved machine. Fig. 2 is a vertical section taken in the plane indicated by the line w w of Fig. 3. Fig. 3 is a horizontal section taken in the plane above the mold or jollie and showing the arm carrying the primary turning implement. Figs. 4; and 5 are vertical sections taken in the planes indicated by the lines 00 as and y y, respectively, of Fig. 2. Fig. 6 is a horizontal section taken in the plane above the mold or jollie and showing the arm carrying the secondary or finishing, implement. Fig. 7 is a vertical section illustrating the same. Fig. 8 is adetail perspective view of the primary turning or shaping implement. Fig. 9 is a detail of a modification. Fig. 10 is a diametrical section of a sectional mold or j ollie which I prefer to employ in my machine, and Fig. 11 is a transverse section taken in the plane indicated by the line at a: of Fig. 10.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to which-- Aindicates the frame of the machine, which may be of any suitable construction and need not therefore be described in detail, and B indicates avertical shaft which is journaled in suitable bearings in the frame and is provided with a loose pulley O, shown'as stepped, which is designed to receive a belt from a suitable motor. This shaft B is also provided with a clutch D, designed to fix the pulley G on the shaft, and mechanism a b c d for moving said clutch into and out of engagement with the pulley; but as said clutch and the mechanism for adjusting it form no part of my invention they need not be particularly described. Upon its upper end said shaft B is provided with the tray E, which has for its purpose to support the mold or j ollie F',which turns with the shaft.

G G indicate vertically-disposed and movable rods which are arranged in suitable.

guides 'e on the frame A. These rods are provided with horizontal arms H H, which are preferably mounted upon and fixed to them between collars f. Said rods G G are connected at their upper ends to cables I, which take over pulleys g on the frame A and carry weights J, the purpose of which is to counterbalance the weight of the rods and thereby ease the upward movement thereof as well as render their upward and downward movements steady. 1

The rods G G are designed to be moved up and down by hand, and the rod G is also designed to be moved up by the shaft B through the medium of the mechanism better shown on Sheet 2 of the drawings. This mechanism comprises a rack h, having collarsh loosely arranged above and below collars h on the rod G, a worm-gear 'i, fixed on the shaft B, the bell-crank lever j, having the pedal portion 1 and the upwardly-extending portion m, the shaft 0", journaled in the upwardly-extending portion m of the lever and pivotally mounted at its opposite end in frame A, the pinion s on shaft r, which always engages the rack h, the worm-wheel t on said shaft for engaging the worm-gear t', and the spring a, connected to the lever j and the frame A and adapted to-normally hold the worm-wheelt out of engagement with the worm-gear i. In virtue of this construction it will be seen that with the shaft B rotating when the pedal portion of the lever j is depressed the wheel will be carried into engagement with the gear 1', and the pinion 3 being in engagement with the rack 72. the shaft 0" will be rotated and the rod G will be raised for a purpose presently pointed out.

K indicates the primary turning or shaping implement of my machine. This implement K has its shank connected to the arm H, preferably by aset-sorew, as shown, and it is curved, as indicated by a in Fig. 8. The implement K is also approximately wedge shape with its sharp edge arranged so that it will first be engaged by the clay, and consequently it will be seen that when the clay is rotated with the mold or jollie which contains it the clay passing over the wedge-shaped portion of the implement will be raised up the side of the profile or former.

L indicates the secondary or finishing implement of the machine. This implement L is connected to the arm II on rod G, and it has the angular branch "U at its lower end, and also has said branch U and its vertical portion beveled, as illustrated, for a purpose described.

Both of the arms II II are provided with adjustable screws L designed to bear upon the lower guide-plate c and thereby limit the downward movement of the arms and implement, so as to regulate the thickness of the bottom of the piece of ware being made, and said arms are also provided with depending handles M M. (Better shown in Fig. 1.)

N indicates curved bars which are arranged one above the other and are connected with the frame A, as better shown in Figs. 1 and 3, and P indicates an upright bar which is adjustably connected with the bars Nfpreferably in the manner shown, so as to permit of it being laterally adjusted for a purpose presently described. The bar P is provided with a longitudinal rib Q, and this rib is designed to be engaged by a spring-catch R on the handle M of arm II for a purpose presently to be described. The said bar P is also provided with a keeper S for the engagement of a spring-pressed latch T on the handle M of arm II.

In the practical operation of my improved machine a sufficient quantity of clayis placed in the mold or jollie and the sameis placed on the tray E. The clutch D is now moved into engagement with the pulley C, so as to cause the shaft 13, and consequently the mold or j ollie, to rotate. The rod G is then lowered, so as to move the implement K down into the jollie until the screw L engages the lower guide-plate 6, when the catch R of handle M is placed in engagement with the guide Q on upright P, said upright having previously been adjusted and adj ustably fixed to determine the thickness of the article it is desired to make. IVhen this is done, it will be seen that in virtue of the peculiar shape of the implement K the clay will be caused to rise, as shown in Fig. 4:. The pedal-lever j is now depressed when, as before described, the implement K will be gradually raised to the upper end of the mold or jollie, shaping the clay as it moves upwardly and spreading the same evenly against the inside of the mold or jollie. \Vhcn the implement K reaches the upper end of the article being formed, the catch R is disengaged from the guide Q and the arm II is swung laterally out of the way. The arm II is now swung laterally, so as to carry the implement L to a position above the article being turned, and the rod G is moved downwardly, so as to carry said implement L into the article being turned. The latch T of handle M is then placed in engagement with the keeper S on upright P. In virtue of the implement L being secured, as described, it will be seen that the operator is free to use both hands in finishing the top of the turned article, cutting off surplus clay, rounding the rim, and sponging, which is an important ad-' vantage. \Vhen the article being turned is completed, the implement L is raised and swung out of the way and the mold or jollie and its contents removed from tray E by any suitable means, after which the turned vessel is removed from the former, when the operation described is repeated.

The implement L is secured to arm II in such a manner that in making bulged ware the said implement, after being brought down into the mold or jollie, can be moved outwardly on arm II.

It will be observed from the foregoing that the implement K is raised in the mold or j ollie at a speed corresponding to that of the shaft 13, the movement of said implement depending on the movement of the shaft 13, so that when said shaft B is rotated at a low speed the implement will be slowly moved upward, and when said shaft B stops from any cause the upward movement of implement K will cease. Consequently it will be seen that if the shaft B is casually stopped, as by the belt slipping off pulley C, no harm can result to the article being turned.

In Fig. 9 I have illustrated a modified construction in which the rod G is made stationary and the arm II is connected to a sleeve A, slidable on said rod, the said sleeve being connected by a cable I with a weight J, as shown.

In Figs. 10 and 11 is shown the sectional mold or jollie F, which I prefer to employ in my machine. This mold or jollie may be formed in three or more sections, although I prefer to have it comprise the two diametrical sections a and the bottom section b as shown.

The diametrical sections. a are provided at their lower ends with inwardly-directcd flanges which are designed when said sections are connected together to form a ledge c for the purpose of supporting the bottom section which is rabbeted, as indicated by (1 Said sections a are also provided at their meeting edges with dowels c and sockets f for the same, the purpose of which is to hold the sections a in proper relation to each other.

The sections (H, with the bottom section Z1 between them, are securely held together by a hoop-clamp g or other suitable means, and the profile or former thus formed is adapted to be used in the same manner as the profile or former F.

After an earthenware vessel is formed in the mold or jollie F the latter is lifted by its handles h from tray E and placed upon a suitable support. The jollie is then let remain a sufficient length of time to enable the sections, which are preferably of plaster, to draw the water out of the clay forming the vessel. The hoop -clamp is then removed, after which the sections a maybe drawn laterally away from the vessel, leaving the same upon the base-section b This may be safely done whilethe clay is soft, and is advantageous because it permits of handles being put on the vessels after they are molded and also permits of. any imperfect vessels being readily perfected. The vessel is left upon the basesection until it is sufficiently hard to be lifted safely, when the base-section may be removed from beneath.

Having thus described my invention, what I claim is 1. In a machine for turning earthenware vessels, the combination of a main frame, a rotary jollie, an upright adjustable horizontally with respect to the former and provided with a vertical guide and also provided with a keeper, means for adjustably fixing said upright, an arm movable vertically and laterally in the main frame and provided with means for engaging the guide of the upright, a turning implement carried by said arm, a second arm movable vertically and laterally in the main frame and provided with a latch for engaging the keeper on the upright, and a turning implement carried by said arm, substantially as specified.

2. In a machine for turning earthenware vessels, the combination of a main frame, a rotary jollie, an upright, adjustable horizontally with respect to the jollie and provided with a vertical guide, means for adj ustably fixing said upright, an arm movable vertically and laterally in the main frame and provided with means for engaging the guide of the upright, and a turning implement carried by said arm, substantially as specified.

3. In a machine for turning earthenware vessels, the combination of a main frame, a rotary mold or jollie, an upright adjustable with respect to the mold and provided with a keeper, means for adj ustably fixing said upright, an arm movable vertically and laterally in the main frame and provided with a latch for engaging the keeper on the upright and a turning implement carried by said arm, substantially as specified.
