This-invention relates to new and useful improvements in a trouser seam pressing machine. j y ,p The invention has for an object the provision of a device of the class mentioned which is of simple durable construction, dependable in use and efficient in action, and which can be manufactured and soldat av reasonj able cost.

16 The invention proposes a counter-balance lever with a heated presser driver roller lengaging with a presser idler roller upon operation of a means for closing the said lever,

:i3 which is'pivotally Imountedupon a vertical i portion of a base. A seaml spreader and cloth dampener is also mounted to the front of the said driver roller. The invention further proposes ameans for alternately turn- .fy ing the driver roller in opposite directions 26 for pressing the seam in several stages and moving the roller forward more than backward so that the seam jis `move/d forward.

For further comprehensionv of the invention, andof the objects andadvantages there VAai; of, reference willfbehadto the followingde-` scription and accompanying drawings, and.

to the appended claims in which `the various novel features ofthe invention are'more particularly set forth. e e 3b' In the accompanying drawings forming a material part of this Ydisclosure:+v

The trouser seam pressing machine consistsof a bracket having a base portion 10 connected with a vertical portion 11 fo'rmed with a lateral projecting portion 12,'a press- 50 er idler roller 13 mounted on and near the showing freev end yof said projecting portion'l2, a counterbalanced lever 14 pivotally mounted onsaid vertical portion'll, a heated presser driver roller 15 mounted on said lever 14 in line with'the idler roller 13, means for rotat. 55 ing the driver rollerl, means for moving said lever to bring said rollers into 'pressing engagement 14 so that the rollers engage each other, and a seam spreaderl and cloth damp- TS2 ener 17 mounted on saidy leverY 14 to the front 60 of said driver roller. j V

The bracket 10 is formed with a flat bottom 18 forl resting upon a table or bench, and being attached thereon. The projecting por-V t'ion'12 formed with a recess 19 in which 65 the idler roller 13 engages so that it slightly protrudes from the top. A transverse .pin 2,0'is mounted across theV recess and the roller is supported upon this pin by ball bear-V Le ings21.- The lever 14 is pivoted intermedi 70 ately at 22 and its rear end supports arod 23 provided with a slidable weight 24 con-v stituting lpartial counterbalancing lof ythe lever.; ,The counterbalancing is concluded withv a motor- 25 mounted upon the lever 14 to theu rear ofthe pivot 22. A l i The lever. 14 `is formed with a downward turned-frontl end26 carrying pillarf blocks 27 supportingthe saiddriverv lroller 15. This '21.1

roller.- is y yof hollow construction as shown in Fig. 3, and a coaxial gas Vpipe 28 extends into the hollow. Thisfgas pipe is provided with burnerr openings- 29 ignitable thru a passage 30 formed in the roller. j The'4 roller et; 15 isv alsoheated by an exterior burner 31 connected with'a {ieXible gas pipe 32. The means forE rotatingthe driver roller V15' consistsV of anezl'ctendedshaft 33 from the roller and connectedwith a pulley 34 engaged by a belt 35H`also engagingth'e pulley of the mo- 90 tor 25.l .i Y

`The 'means .for closing the lever 14 con-v sistsof a radialarm 36 having one end connected coaxially on the lever 14 and a connecting link 37 eXtended downwards and con.- nected'with any conventional foot; pedal not shownon the drawing. .1 The seam spreader 16 has a pointed horizontal portion 38 adapted toengagein the seam and spread the two edges open. A screw 39 supports the seam roller 15 in opposite directions vfor pressingv the seam in several stages and moving the roller forward more than Ybackwards so that the seam is moved forwards. This means consists of a shaft 43 supporting the driver roller 15 and vformed at one end with a knurl-ed portion 44. A large drum 45 loosely'engages the knurled portion 44 and carries coupling jaws 46 slidably arranged, so vthat in depressed conditions rotations from the drum 45 are communicated to the shaft 43. A spring 47 is secured upon the drum V45 and engages the'jaw 46 so as to normally urge it into a slightly extended position constituting the disengaged condition of the jaw.

A band 48 encircles the drum 45 and is adapted for depressing the jaws 46 into their operative conditions. This is accomplished by a spring 49 acting between the ends 50 of the band kfor normally contracting it. A rod151v isslidably mounted upon the lever 14 and passes thru one ofthe ends'50 and engages against the other of the ends so that upon forward motion, vit may spread the ends'for yslightly opening the'band.l The 5 end 50 thru which the rod 51 slidably passes is Xed asiat 52 upon the lever 14. V*A'spring 53.y acts between therod 51 and the'lev-er 14 for normally Vurging the rodY rrearwards against, a small Wheel 54 fixedV upon ashaft 55 carrying a pulley 34 engaged by the said belt 35.` Y The small wheel 54 is provided with approjecting camportion'56 extending about one quarter of its periphery.A A pin 57 eccentrically projects from the small wheel 54 and 'i supports one end of a connecting rod 58 whose other end is supported'upon a pin 59 eccentricallyl mounted uponthe large.

drum 45.' i i a .Rotations fromV the pulley 341 are transmitted 'pto/the smallj wheel 54.v Motion of wheel 54 causes the 'connecting` rodA 58 to reciprocate and rock thedrum 45 forwards and rearwards. VVThis rocking motion 1s transmitted to the presser roller 15. Each `time* the drum 45 to idle during part of its oscillations. Obviously, for each rotation of the wheel 54the drum 45 goes forward and backwards but in the backward movement only part `'of the motion is transmittedto the presser roller l5 which causes the seam being pressed to advance.

In operation of the device, a trouser leg, as schematically indicated by dot and dash lines 62, is` engaged upon the lateral projection 12 so that the seam 63 engages upon the idler roller 13. Then the pedal is depressed for moving said lever to bring said rollers into pressing engagement, so that the driver roller 15 engages the seam. The spreader 16 vopens the seam and the material being pressed is dampened by drops from ythe Acontainer 40.1..- When the seam is completely pressed, the pedal is released so that thevlever 14`opens-.Yl `-N'ext the trouser leg is turned thru an angle of 180 degrees. so. that the other seam 64 may be similarly pressed.V

` While I have shown and described'the pre-` ferred embodiment of my invention, itis to be understood that l do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modiiications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure byUnied States Letters Patent is 1. A trouser seam presser machine, comprising a bracket having a base portion connected with a vertical kportion formedwith a lateral projecting portion, va presser idler "il roller mounted on andV nearA the freeendof said projecting portion, a counterb'alanced lever pivotally mounted on said vertical-por-V tion, a heated presser. driver rollermounted on said lever in vertical alignment with said idler roller, ymeans for'lrotating the driver;
