This lever has the upper arm of the T- rear end extending at an obtuse angle to receive the lower end of the link 11 to which it is pivoted by shaped and divided ose details of the con- 1S. and the 1 showing the pressing to by the pin 20.

of the shaft frame broken away to suitable manner,

a pivot pin lower arm of the T-shaped rear end of the lever 16 is extended at an obtuse angle and likewise divided to receive the upper end oftlielink 19 which is pivoted there- A socket 21 is secured on the lower end 5 by the pin 22,

or in any other and has a pair of bearing lugs 23 extending forwardly therefrom and embracing the lower end of the link 19 to which these 7 the pivot shaft 24.

The rear at a point rawings, the reference base of the machine formed integral with lards 2 which are conby the set screw 26. said to 3 and a transverse have their forward ends upright standard 5 is ends engaged on ects upwardly through lugs are pivotally connected by end of the lever 16 is connected between the pivots 18 and to a collar 25 which is held, on the shaft 5 connection comprising the links 27, which are arranged respectively at the opposite sides of the shaft 5 and engaged on the pivot pin 28 of the lever 16, and have their rear 95 pivot studs 29 which project laterally from the collar 25.

The collar 14 and socket member 21 are of the side frames formed at each side with laterally projecting lugs 30 and 31 respectively which terminate close to the opposed parallel flanges 32 2 to prevent lateral displacement of the shaft 5.

A heavy spring 60 has its lower end connected to the lever. 16 a short distance in front of the pivot pin 28 and has its upper end connected to a hook 61 on the under side of the top 3 so as to hold the lever 16 in the elevated position as shown in Fig. 4.

From the foregoing it will be observed that the shaft 5 which carries the presser head, i hung from the frameof the machine by the links 11 and 19 and the T-end of the lever 16 in substantially the same manner as shown in the structure of the patent to Schrom No. 1,004,697. In the structure of said patent, however, the lower end of the upright shaft which carries the presser head is stayed by a pair of links which are ivoted to the frame of the machine and to the socket at the lower end of said shaft, and the latter has practically only an up and down movement.

In my construction, however, the socket 21 at the lower end of the shaft 5-, is connected to the lower part of the side frames 2 by toggle links 33 and 34, which are pivoted together at their inner ends on the pivot 35, and the outer ends of the links 33 are pivoted on the shaft 24 of the socket 21, while the outer end of the toggle link 34 is pivoted on the shaft 36, which has the opposite ends engaged in corresponding bearings 37 of the two side frames 2 as indicated particularly in Fig. 3.

A pair of links respectively at opposite sides of the lever 16 and toggle link 34, are pivoted at their up er ends tothe lever 16 by the pin 39 and have their lower ends pivotally engaged on the shaft 35 so that when the lever 16 is in the elevated position shown in Fig. 4,

the toggle joint formed by the toggle links- 33 and 34 is broken u wardly, and when the lever 16 is depresse as shown in Fig. 1, the toggle links 33 and 34 are swung into substantially an aligning position.

Thus the distance between the stationary shaft 36 and the shaft 24 is shortened when the lever 16 is elevated, andthe lower end of-the upright shaft 5 is accordingly moved forwardly to tilt and raises the shaft 5 rearwardly at a slight angle to the vertical as shown in Fig. 4, with the result that the carriage for the presser head is tilted slightly. This not only serves to increase the elevation of the pressing member above the pressing buck to facilitate insertion and removal of the clothes and increase the capac ity but also tends to slide the pressing element rearwardly by gravity to the retracted position and facilitates operation of the That is, the shaft 5 is 38 which are arranged oscillated forwardly and rearwardly onits horizontal axis near its lower end and raised when swung rearwardly by the raising of the treadle 17 when released, and is swung forwardly and lowered when the pressed on the pressing'buck, and also serves to exert a powerful leverage on the lower end of the shaft 5, as the links 11 and 19 and the end of the lever 16 are straightened out, and imposes an exceedingly high pressure of the pressing element against the article'on the pressing buck, and accomplishes this high pressure without great effort on the part of the operator.

The shafts 24 and 36 are preferably extended sufficiently to accommodate a pair of springs 59 which connect the corresponding ends of these shafts and serve to facilitate the elevation and rearward movement of the pressing mechanism and breaking of the toggle joint connection of the links 33 and 34 and bend this articulated joint upwardlyas seen in 4 by drawing 24 toward 36, and thus 21 and -5 forwardly. The opposite action takes place when the tread'le 17 is depressed.

The carriage which has been hereinbefore referred to, is indicated at 40 and consists of an elongated head with an opening extending therethrough from end to end to loosely receive the bar 41 which is engaged between the upper and lower'anti-friction rollers 42, which are journaled in the head and permit easy sliding movement of the bar 41 through the head. This head is formed with a pair of vertically spaced collar portions 43 and 44 which embrace the upper end of the shaft 5 and have a collar or sleeve 45 interposed therebetwcen and secured on the shaft 1" by the pin 46 or in any other convenient manner.

In cases where this machine is provided with an ordinary iron which it is desired to move along the upper surface of the pressing buck, the collars 43 and 44 are free to turn on the shaft 5. In the present structure, however,-a pressing element 47 is employed, which merely clamps down against the top of the buck 48 and as sidewise lateral movement or oscillation is not desired, the

points by means of thescrews 51 to the ends of the cross head A handle 52 is attached to the front of the pressing element 47 for convenient manipulation of the latter.

Extending lengthwise within the heating element 4.7 is a gas burner 53, which has an inlet pipe 54 connected thereto at the center, and this inlet pipe is connected through the manually operable valve 55 by the hose 56 to a gas supply pipe 57, the hose belng sufliciently loose and suitably caught up as indicated at 58 so that the pressing element may be readily raised and lowered and moved backwardly and forwardly on the pressing machine.

A similar gas burner 62 is mounted under the top plate of the pressing table 48 and has the inlet pipe 63 at the center connected through the manually operable valve 64 and tubing 65 to the main supply pipe 57. A valve 66 which is automatically operable by a thermostat, is connected to the supply pipe 57 so as to simultaneously control the admission of gas to both of the heating elements 53 and 62, the device of this auto matic valve not being shown, as such valves are already on the market, and any suitable thermostatically operated valve may be employed. A thermostatic element (37 is mounted by means of brackets 68 under the top plate of the pressing table 48 and connected by means of the tubing 69 with the automatic valve 66 in the usual manner for controlling the operation thereof. .A. handle 70 on this valve serves to set the latter at any desired temperature which is automatically maintained by the valve through the medium of the thermostatic element 67.

With this construction, when the handle 70 is set at the temperature desired for pressing, the flow of gas through the tubes 56 and 65 to the burners 53 and 62 is automatically regulated so as to maintain the required temperature. A manually operable valve 71 is provided in the supply pipe 57 for entirely shutting off the supply of gas.

For limiting the movement of the lever 16, the cross brace 4 of the main frame is provided with a suitable inset bumper 72, and the base of the machine with a similar inset bumper 73, which project sufficiently and are composed of suitable material to cushion the impact of the lever at the extremities of its movement. The cross brace 4 is also formed with a transverse rib 75 with which a latch 76 on the treadle cooperates for holding the treadle in the dc pressed position. This latch76 is pivoted at 77 and has a laterally offset extension 87 which projects below the treadle and is connected to a spring 78 which serves to throw the latch 76 into engagement with the rib 75. An operating lever 79 is pivoted at 80 near the lower extremity of the extension 87 and has an upwardly extending arm 81 connected by the spring 82 with the upper end of the extension 87, and this operating member 79 extends forwardly and has a stem 83 projecting up through the treadle 17 and provided with a button or small plate 84 at the upper end, which may be depressed to release the latch 76 from the rib 75.

, An extension 85 is hinged at each side of the top of the pressing machine and held in the elevated position by a brace 86 extend ing down to the base of the machine.
