Application filed May 23, 1911; Serial No. 628,981.

To all whom .z't may concern:

Be it known that we, ERNEST M. GLAS- oow, a subject of the Crown of Great Britain, and MONROE SUNSHINE, a citizen of the United States, and residents of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Garment-Pressing Machines, of which the followingis a specification.

Our invention relates to garment pressing machines and has for its object to provide novel means whereby the pressing iron may subject the work to great pressure with a minimum amount of movement of the foot lever, a power multiplying mechanism being introduced between the lever and the iron carrying plunger for accomplishing the result above stated.

A practical embodiment of the invention is represented in the accompanying drawin s, in which,

ignre 1 represents a machine embodying our improvement, the machine bein shown in vertical section with the parts in the position which they assume when the foot lever has been depressed to the limit of its move ment. Fig. 2 is a detail sectional view similar to Fig. 1, with the parts in the position which they assume when the foot lever is at the limit of its upward movement, and Figs. 3, 4 and 5 are diagrams showing the first and intermediate and the final position of the power multiplying connection between the foot lever and plunger.

A suitable frame 1 forms a support for.

the work table 2, the plunger bracket 3 and the foot lever 4. The presser iron 5 is carried by an extensible member 6 of the presser arm 7,'which presscr arm is hinged at 8 to a collar 9 carried by the plunger 10. This plunger 10 is fitted to reciprocate vertically in upper and lower bearings 11, 12, 01". the bracket 3. Diagonal tension rods 13 (one of which is'shown in the accompanying drawings) connect the outer end of the presser arm 7 with a collar 11 fixed to the plunger 10 intermediate the upper and lower bearings 11, 12 or the bracket 3. The foot lever 4 is hinged at 15 to the frame 1, at a point below the plunger 10. A hanger 16 is secured to the lower end of the plunger 10 and an uprising rock arm 17 is pivoted at 18 to the hanger 16. A11 inner rod 19 is piv otally attached at 20, to the rock arm 17, adjacent to its axis 18, and is pivotally attached at 21 to the foot lever 4, adjacent to its axis 15. An outer rod 22 is pivotally attached at 23, to the rock arm17 at a point beyond the point of attachment 20 of the inner rod 19, and 1s plvotally attached at 24; to the foot lever 4 at a point beyond the point of attachment 21 of the inner rod 19 thereto. The point of attachment 20 of the inner rod 19 to the rock arm 17 is at a point to the rear of a line drawn through the axis 18 of said arm 17 and the point of attachment 23 of the outer rod 22 thereto. A spring 25 serves to automatically return the plunger 10 and foot lever 4 to their normal raised position, which sprlng is attached to a lug 26 on the bearing 12 of the bracket 3, and to a lug 27 on the hanger 16. l

A spring cushion is attached to the frame in position to be struck by the foot lever at as it approaches the limit of its upward movement, for cushioning the blow. which CUShlOIl is herein shown as comprising a plunger 28 having a collar 29 fixed thereto between which collar and an abutment 30 is interposed a cushioning spring 31.

In operation, presupposing the parts to be 111 the position shown in Fig-s2 and 3, as the foot lever at is depressed by the operator, the plunger 10 will be drawn down at a constantly decreasing speed because of the double rod connection between the rock arm 17 and the foot lev'er 4. The points of, connection at the upper ends of the rods 19 and 22 with the rock lever 17, are so arranged that the depression of the lever 4 will cause the rod 22 to swing the point'ot' connection 20 of the rod 19 with the lever 17, toward a position above the axis of the said rock lever 17. As this point 20 approaches its position above the axis 18, the downward movement of the plunger 10 grows less and less, while the powerof the operator is increased owing to the shifting of the pull from the point 24 entirely to the point 21 on the lever 4 adjacent to the axis 15 of the lever. It will thus be seen that a novel power multiplying connection is provided between the lever 4 and the plunger 10, which connection will permit a comparatively rapid downward movement of the plunger and thereby the pressing iron during that part of the stroke where the iron is doing no work and a very slow and poweri'ul movement during that part of the stroke there the iron is doing its work. .A further advantageous feature is the hinging of the presser arm 7 to the plunger and the provision of the diagonal tension rods 13 so that the arm is relieved of any breaking strain thereon and the said rods serving to receive the said strain instead.

\Vhat We claim is: V

1. In a garment pressing machine, a vertically reciprocating plunger, a foot lever for depressing said plungen'means for automatically returningsaid' plunger and foot lever to their normal raised position and a power multiplying connection between the foot lever and plunger comprising an uprising rock arm pivoted to the plunger, and inner and outer connecting rods leading from points on the foot lever at different distances from its axis to points on the rock arm at diflerent distances from its axis.

2. In a garment pressing machine, a vertically reciprocating plunger, a foot lever for depressing said plunger, means for automatically returning said plunger and foot lever to their 11or1na1 1'ai sed position and a power multiplying connection foot lever and plunger comprlsmg an uprising rock arm pivoted to the plunger, inner and outer connectingr'ods leading' fi om points on the foot lever at different distances from its axis to points on the rock arm at difl'er'ent distances from its axis, the points of attachment of the connecting rods to the rock arm being such thafiasthfoot lever is depressed the point of attachmentof the inner rod to the rock arm is moved into position over the axis x ofssaid noel In testimony, that we claim the fioregoing ERNESTYM or s MON ROE SUNSHINF WVitnesses: I i
