l in the pressing of seams during the process of clothing manufacture.

An object of the invention is to provide a pressing machine which will feed the goods to be pressed automatically beneath a pressll ing iron, will apply pressure to said iron, and one which will steam and dry the goods duringthe pressing operation.

A further objectis to providev a visual indicator which shows .the operator when the feed bars yare above the surface of the table, so that the machine when cut off from the power operating member may be adjusted by the operator to bring the feed bars below the base so that the goods may be drawn out of the machine without damaging or marring the same.

A still further object of the invention is to provide a machine in which the vertical throw of the feed bars may be adjusted to compensate for goods of various thicknesses.

A still further object of the invention is to provide a compact e'tiicient machine which will automatically feed goods to be pressed beneath an iron, and one in which the parts will be so arranged that the steam is ad-l mitted to the goods intermittently and the iron is heated by the steam, a part of which isarrangedto moisten the goods just before the saine is pressed.

Referring to the drawings in detail 5 indicates a table comprisinga topk 6 and supporting legs 7, the forward part of the table being extended as at 8 to provide a support for the overhanging goods lbeing pressed.

The table top 6 has attached at;` the rear' thereof a housing 9 to the front of which is secured the base 10 which projects forwardlyv and forms a pressing base upon'which the iron 11 is normally adapted to rest, the iron being `pivotally held as at 12 in the arm 13 which is formed integrally with, and constitutes a part of vthe iron support 14, the body of whichis hollow and has its lsides pivotally associated as at 15 with the housf ing 9, so that the support 14 can be rocked about its pivot point to raise and lower the iron from the base 10. This raising and lowering movement is carried out through the medium of a lever 16 `which is pivoted to a bracket 17 carried on the forward table leg 7 to which is attached a tie rod 18 which connects with another lever 19 eX- tending rearwardly to its pivot point in a bracket 20 on the rear leg 7. Adjacent its bracket connection, thevlever 19 is connected as by a tie rod 21 to a link. 22, the rear end of which is pivoted as at `2,3 ona bar24 connecting the sides of the housing 9, and the link carries the' lower end of,` a rod 25 the upper end ofwhich connects with the extended portion 26 of the iron support 14. A suitable pedal '27 is used to operate the lever 16 through the connecting chain '28. Any pressure upon the pedal therefore will cause the iron to be raised off the basel 10,I so that the goods can be drawn from beneath the iron.

The iron is composed of a hollow chamber portion-29 having amid-rib y3() extendingr longitudinally thereof and tnding adjacent the front wall of the iron to provide a passageway through which the steam passes. One side of the iron is provided with an outlet 31 opening out of the compartment while the top plate 33 of the iron whiohis pivoted to the arm 13 is provided with a steam inlet 34, the steam passing through a circulation which ke'ps the-iron hot.

5"' steam through a pipe 37 which connects valve 36 with a normally closed valve 38,

the latter being disposed on a vertical pipe,

39, the lower end of which is secured in the Abottom of the iron against a small baffle 40 having openings therein. `This allows th goods to be properly moistened by the steam before passing rearwardly, it beiiigunderstood that thel steamA is emitted at a point adjacent the front of th;x iron. The stem 41 *i of the valve 38 extends upwardly through a suitable Aopening in the fiont ofthe arm 13 and carries beneath and spaced from said arm a collar42`, there being interposed-betwe'en the collar and the arm, a'spring 43,

which normally maintains the valve '38 The collar 42 is'engaged by the forked end of a bell-crank 44 whichi's pivoted in the larm 13 as at 45 and'is operated through a rod 46 which extends'tlirough said arm 13 rearwardly'to engage the 'upper endY of a cain operated lever 47 which is pivoted at its mid-,portion as at 48 to the support 14, while its lower end is bifurcated to it *"around an eccentric cam"49.

The cam 49 is secured to the power shaft 50 which passes through .the housing 9 and carries thereb'eyon'd they clutch members 51 and 52, the latter of which is movable through the medium of a lever 53 hereinafter referred to, andthe member 51 of which carriesa gear 54. 1The gear 54 is` operated by the pinion 56, whichissecured tothe motor shaft 57, the motor 58 being mounted upon thetable. They shaft 50 on the opposite end, which extends beyond the housing 9 carries a fly wheel 59 andan ec--` centric cam 60, the latter being capable of A voperating a lever 61 pivotedas at 62 to the housing 9 and attached at its upper endto the `longitudinal link 63 whichvoperates a vertical indicator ,'64 pivoted on the front part of the arm 13 and in position to .regster with a fixed marker 65 at times, depending upon the position of the feed bars to b.: hereinafter referred to.v

The power shaft 50 within .the housing (Figures 4 and 5) carries a plurality of eccentric cam members, 66, 67 and 68, the cams 66 and 68 carrying the stiap members 69 and 70 respectively, the extended portion 71 of the strap 69 holding in its outer end a headed pin 72 having an Cccentric portion 73 thereon which carries the end of a feed bar raising lever 74 the eccentric portion being provided with a slotted head 75. The pin 72 is frictionally held in the portion 71 of the strap 69, and when adjustment of the lever 74 is desired the slotted headL 75 is turned thereby turning the eccentric poi.'- tion 73 to shorten thefoverall length of the strap 69 and lever 74.

To the lever 74 are pivoted as at 76 the bell-cranks 77 which are pivoted on cross bars 78 in the base 10, the horizontally disposed feet'79 of the bell-cranks engaging and supporting the plates 80 to the upper side of which are secured the spaced feed bars 81, havii'ig their upper longitudinal edges serrated whereby the goods may be drawn rearwardly through the machine upon a rearward movement of the feed bars. In the position shown in Figure 1 the feed bars 81 are flush with the upper surface of the base 10. The fe d'bars are reciprocated through the medium of the strapeX- tension 82 which is part of the eccentric strap 7() operated by the eccentric cam 68, the extension 82 being pivotally connected as. at 83 to the rear feed bar plate 80.

It is evident therefore that areciprocating motion imparted to the lever 74 will,y

through the bell cranks 77'` raise the feed' bars above the surface of the base. A reciprocating movement of the strap extension 82, imparts a reciprocatory movement to the feed bars 81 which slide on top of the horizontal foot portions 79.

shows when the feed bars are above or below the base 10. f v

As shown in Figure 8 when the indicator 64 is atits forward position the feed bars are below the surface of the table or base The lever 74 is` advanced and thenthe feed bars are retracted, the advance causing the feed bars to 130 10 and the goods can be safely drawn out of the machine; when the indicator is in register with the marker the feed bars are above the base and in order to bring them belowl the base,'I make use of a manual adjustment which comprises .a lever 84: pivoted to the forward leg 7 of the machine above the lever 19 and connected thereto by a link 85 the free end of the level' being yieldably held in horizontal position by a spring 86 suspended from a brace bar or rod 87 connecting the sides of the housing 9. To the power shaft 50 there is fixed a ratchet wheel 87 over which travels the pawl 88, the same being pivoted to a rock lever 89 which is mounted loosely on shaft 50 and is rocked by a depending rod 90 pivoted to its extended free end 91. The rod 90 at its lower end is pivoted to the lever 84. i It isevident that a pressure on the foot lever 27 will move the levers 19 and 84 downwardly to cause a throw of the ratchet pawl 88 which carries the ratchet' wheel 87 with it and thus turns the shaft 50 to position the feed bars below the surface of base 10.

In order -to provide for the goods being thoroughly pressed, I apply pressure to the extended portion 26 ofthe iron support )14 whereby the iron is pressed firmly on the table or base 10, through the medium of a coiled spring 92 held between two cu'ps'the upper of which 93 is pivotally connected` engaged by one end of a rocker 99 which is travel through the machine.

vpreviously referred to. that it will force the end of the rocker down pivoted on rod 87 and has its opposite end extending beneath and engaging the cam 67 The cam 1s so cut when the feed bars are above the surface of the table and travelling rearwardly, so that the iron will press the goods firmly during Downward pressure on the pedal 27 will, as before described raise the iron 0H the base 10, but

the spring 92 will normally press the iron firmly against the base 10.

In order to control the power applied to Y the machine by the throw of the clutch member 52 which is performed by the lever 53 I connect the latter, through the medium of a tie rod 100 with a longitudinally disposed lever arm 101 beneath the table pivoted at one end to a bracket 102 held on the rear leg of the table, the free end being connected with an auxiliary lever 103 by a rod 104. The lever 103 is pivoted to a bracket 105 held on the front leg of the table and is operatively connected to a pedal 106 by a chain 107. To start the machine the pedal 106 is therefore pressed downwardly against the action of spring 108 which extends betweenthe bottom of the table and the lever It will be evident that I have provided an efficient and durable pressing machine, which will handle the material at high speed and which will also guard against damage to the goods when the same is to be drawn from the machine. Also I have provided a machine in which the goods are moistened 'intermit-- tently and fed by a step by step motion through the machine to` be thoroughly pressed.
