SPECIFICATION forming part of Letters Patent No. 389,971, dated September 25, 1888.

Application filed July 25, 1887. Serial No.2l5fi63.

To all whom it may concern:

Be it known that I, JEAN LoUIs MAZOYER, a citizen of France, and at present residing in the city, county, and State of New York, have invented a new and Improved Ir0ning- Machine, of which the following is a full, clear, and exact description.

My invention relates to that class of ironing-machines in which ahcated polishing-cylinder moves upon the articles to be ironed and polished, said articles being held in position on a bed or table to receive the action of said cylinder.

The invention consists in the construction and arrangement of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement. Fig. 2 is a plan view of the same. Fig. 3 is a vertical cross-section of the same on the line 00 x of Fig. 1, looking in the direction of the arrow ac. Fig. 4 is afrontelevation of the polishingcylinder support, with the polishing-cylinder partly in section. Fig. 5 is a side elevation of the mechanism for rotating the polishing-cylinder when its support is not oscillating. Fig. 6 is a side elevation of thede vice for operating the mechanism shown in Fig. 5. Fig. 7 is a plan view of the supporting-arm for the ironing-table. Fig. Sis a side elevation of the shifting mechanism. Fig. 9 is a vertical erosssection of the ironing-table and its support on the line {111/ of Fig. 1. Fig. 10 is a detailed view of the catch for holding the shifting-lever in position, and Figs. 11 and 12 are detail views of the device for locking the roller to which the article to be ironed is secured.

On asuitably-construelied frame, A,is mounted the driving-shaft 13, carrying the fast and loosepulleysOandO,respectively conneeted,in the usual manner,by a. belt with machinery for rotating said driving-shaft I3. On the driving-shaft B is secured a pinion, D, which meshes into the gear-wheel E, secured to the (No model.)

crankshaft F, mounted in suitable bearings on the main frame A. In the middle of the shaft F is formed a crankarm, F, connected with the lever G, fulcrumed on the shaft G, secured to the main frame A,near its bottom.

In the upper forked end of the lever G is held a shaft, G on which is fulcrumed the middle part of the lever II, also provided at its rear end with a shaft, H, secured in the slotted forked end I of the vertical arm I, fulcrumed at I" on the main frame A. The shaft H is held in place by the set-screws J and J screwing in said arm I, so that the shaft H may be adjusted vertically in the slotted end of the arm I. The front end of the lever II supports the platform H on which the ironing-table K is heldadjustably by means of the screws K, which screw into said platform H and by the set-screws K and K for adjusting the position of said table K in relation to the platform H On the upper surface of the ironing-table K is held the polishing-cylinder L, provided with the trunnions L, mounted to rotate in the upper ends of the forked lever N,fulcrumed at its lower end on the shaft N, held on the main frame A. The lever N is pivotally connected by the links 0 with the crank-arms I, formed on the outer ends of the crank-shaft F, said crank-arms P standing diametrically opposite the crank-arm F, as illustrated in Fig. 3.

On one of the trunnions L of the polishingcylinder L is secured aratchet-wheel, L", with which engages a pawl, L, pivoted on the hearing of said trunnion L. This pawl L permits the polishing-cylinder L to rotate when moving toward the front end of the machine, but prevents a rotary motion when moving backward, so that the polishing-cylinder L glides over the article to be ironed. Into one of the hollow trunnions L of the polishingcylinder L passes a pipe, Q, which extends into the cylinder-L, and is perforated at its inner end, as illustrated in Fig. 4. To the outer end of the pipe Q leads a gas-pipe, Q, and the two air-pipes, Q so as to lead a mixture of gas and air into the interior of the cylinder L, in which said mixture is burned by igniting it in the usual manner, so that the polishing-cylinder L may be heated.

On the other trunnion L of the polishingcylinder L, which may be either hollow or solid, is secured a ratchet-wheel, R, which engages a pawl, It, pivoted on one end of the bellcrank leverR", mounted looselyon the reduced end of the trunnion L, as shown in Fig. 5. The other arm of the bell-crank lever "t connects by means of the link It with the bellcrank lever R, fulcrnmcd on the main frame A, and connected by the rod R with the eccentric It, mounted on a shaft, R having its bearings in the main frame A at the rear of the machine. 0n the shaft R is secured a gearwhce], It, which meshes into a pinion, 0, formed on the hub 0" of the loose pulley O, rotating loosely on the main shaft B.

()n the lever It is held a device for fastening the articles to be ironed on the table K, and this device consists, principally, of an arm, S, fulcrumcd by its rear end at S to said lever ll, and provided at its front end with a flat holder, S, fitting over the rear end of the table K, as illustrated in Figs. 1. and 2. On top of the arm S operates a cam, S, provided with a handle, S, and fulcrumed on abrackct secured to the lever H. A spring, S, is secured to the same bracket and presses against the under side of the arm S, so that when the handle S is pushed backward, whereby its cam S disengages the arm S, then the spring S causes an upward swinging motion of the arm S, so that its front end, S, is disengaged from the table 1C.

The cloth T is usually placed on top of the table K and held by one end under the free end of the arm S, and by its other end is wound around a roller, T, provided with pins, so as to hold said cloth stretched over the table K. In front of said roller T is held a second roller, T, for fastening the end of the article to be ironed. The roller T is provided with a series of pins, and toils outer end is fitted the handle T". The handle T is provided with the pins T, adapted to engage apertures formed in one of the brackets, K", in which the said roller T" is jonrnaled. To permit the pins of the handle to be engaged or disengaged from the apertures in the bracket, the shank of the handle fits in asocket in the end of the roller, and is provided with a pin, 1, projecting into a slot, t, so that handle will be locked to the roller, but will be free to slide back and forth in the socket of the roller, as clearly shown in Fig. 12. 3y this construction, by pulling the handle T outward until the pins T are disengaged from the apertures of the bracket, the roller T can be turned by the handle so as to stretch the article to be ironed tightly over the table K, after which the handle T is pushed back, when the pins T will enter other apertures in the bracket K, and thus lock the roller T" in the position to which it has been turned.

The shifting-bar U, operating the belt connected with the fast and loose pulleys G and O, is connected with a bell-crank lever,U, fulcrumed on a bracket, U secured to the main frameA. Thcbell crankleverUisconneeted by the link U with an extension, U, projecting from the treadle-arm U, secured at U on the main frame A. The treadle-arm U projects from the front end of the machine and carries a treadle-board, U, for the operators foot. A spring, U is connected with one end of the treadle-levcr U, and at its other end with the main frame A, and has the tendency to pull the treadle-lever U upward, so that the shiftingbar U holds the driving-belt on theloose pulley (.l,so that the machine does not run.

The trcadle-lever U" may be locked in position when in its lowest place by the spring catch V, having the shoulder V engaging one edge of the treadle-board U as illustrated in Fig. 8. A spring, V presses against said catch V, so as to hold the same engaged with the treadle-board U, and said catch is fulcrumcd on a bracket, V", extending from the main frame A.

The operation is as follows: The article to be ironed is placed on the ironing-table K, and fastened by the free end of the arm S and by the pin-roller T, as above described. The operator then presses his foot on the trcadle-board U whereby the fork of the shifting-bar U is moved endwise, so that the d riving-belt passes on the fast (1 ri vi ng-pulley 0, whereby the crank shaft F is set in motion. The rotary motion of the main shaft B is transmitted by the pin ion D and the gear-wheel .l l to the crank-shaft F, which, by its crank-arm l and the lever G, imparts an oscillating motion to the tablelever 1f, thereby oscillating the table K. At the same time the crank-arms I? of the crankshaft F impart an oscillating motion by the links 0 to the lever N, so that the polishingcylinder L swings over the ironing-table K, but in an opposite direction to the latter, on account of the cranlcarms P standing diametrically opposite to the crank-arm F. The polishing'cylinder L, on moving toward the front of the machine, is rotated by coming in contact with the article to be ironed, and moving toward the rear with the table K; but when the latter oscillates toward the front and the polishing cylinder commences its return movement the latter is prevented from rotating by the pawl L engaging the ratchet-wheel L", so that the said polishingcylinder L glides over the article to be ironed. It will thus be seen that the article is ironed by a rotary movement of the polishing-cylinder Ti, and by a gliding movement of the same at the respective forward and backward movement of the said polishing cylinder. The table K can be adjusted by the screws K and the set-screws 1C and K, so that the polish ing-cylinder L will pass evenly over the article to be ironed and held 011 the table K. The lever 1T, supporting the table K, can also be adjusted up and down at its rear end by the set-screws J and J, held in thepivoted arm I, so as to raise or lower the table K. The arti cles to be ironed and hanging over the table K at either side are supported by the trough or chute H, held below said table, and moving with the same on account of being fastened to the lever H. When the operator presses the treadle board U downward, as before described, then the spring-catch V engages the edge of said treadle-board U, thus locking the latter in position, and thereby holding the fork of the shiftingbar U over the fast pulley C. When the operator desires to stop the machine, he presses the spring-catch V toward the rear with his foot, disengaging the same from the treadle-board U so that the spring U pulls the treadle-lever U upward, whereby the shifting-bar U is moved inward and the driving-belt is passed on the loose pulley O. The oscillating movements of the table K and the lever N, supporting the 'polishingcylinder L, have ceased; but the polishing-cylinder is kept rotating in its bearings by the rotation of the loose pulley O, which, by its pinion 0 formed on its hub G, imparts a rotary motion to the gear-wheel R thereby rotating the shaft It". The latter sets the eccentric R" in motion, whereby a rocking motion is given to the bellcrank lever B, and this rocking motion is transmitted by the link 1 U to the bell-crank lever R which, by its pawl It, turns the ratchet-wheel R, secured to one of the trunnions L of the polishingcylinder L, so that the latter is rotated.

Having thus described myinventiomwhat I claim as new, and desire to secure by Letters Patent, is-

1. In an ironing-machine, the combination, with a shaft, of a' polishing-cylinder, a lever on which said polishing-cylinder is mounted, and which lever is connected with a crank-arm on said shaft, an adjustable ironing-tableheld below said polishing-cylinder, and an adjustable lever supporting said ironing-table at one end and connected with the crank-arm on said shaft, substantially as shown and described.

2. In an ironing-machine, the combination, with a crank-shaft and a lever pivoted at its lower end and connected at about the center of its length to the crank of the said shaft, of the lever H, provided with shaft H, theironing-board K, secured to one end of the said lever, the arm I, pivoted at its lower end, and having its upper end slotted to receive the shaft H, and the screws JJ, for adjusting the shaft 11 in the slot of the arm I, substantially as herein shown and described.
