CORPQRATION OF NEW YORK.

To all whom it may concern: I

- Be it known that we, J OHN N. DERSCHUG and GUY C. WI KINSON, of Syracuse, in the county of Onondaga, in the State of New dampened condition and leave the machine in a smooth dry state. I

In ironing articlesby machines of this character, it is first necessary to straighten out the leading edge of the article by hand upon a suitable table andthen to feed said edge by hand between the heating roll and feeding roll in order that the machine may I perform its work automatically and efli-- ciently without any further effort upon the part of the operator other than to see that the remaining portions of the article are straight or flat without wrinklesias they enter between the rollers.

In the use of machines having rigid tables across which the articles to be ironed are fed, it isnecessary to bring the hands into dangerous proximity to the feeding faces of the rollers and sometimes results in seri 'ous burning of the fingers by the heating roll or in painful injuryto the fingers by being caught between the rolls, and one of the main objects of our present invention is to obviate these dangers by providing a supporting table for the articles to be ironed which is movable at will toward and from the rollers and is automatically retracted and normally held away from said rollers a suflicient distance to allow the leading edge of the article to be properly straightened out thereon and alined with said rollers prior to advancing the same to the feeding mechanism so that the advancing movement of the table automatically feeds the straightened edge to the rollers without necessitating the close approach of the fingers thereto.

This machlne may be used in private as well as in public laundries and comprises a main supporting frame having upright end standards 1+ supported by suitable casters -2- to enable the machine vto be easily moved from place to place along the floor,

the standards 1- being spaced a considerable distance apart to adapt the machine be brought out in skirts, aprons and other relatively for ironing relatively wide articles, such as tablecloths, spreads and the like as well as such as napkins,

Handkerchiefs, towels and similar articles.

A hollow cylindrical roll -3 of substantially the same length as the distance between the upright standards 1- is ro-.

tatably supported at its ends upon suitable bearings'4 to rotate about a horizontal axis, the bearings 4f being preferably of the roller type'bearing against the underside of the periphery of the drum 3 to permit the latter to rotate with a minimumamount offriction. v

A gas burner conslsting of, in th1s'1n stance, a radiallyperforated pipe 5 is the baffle plate s-6 to permit the passage of the heated products of combustion to the upper portion of the drum without liability of over heating the same.

The upper ends of the standards 1-- are provided at their outer faces with similar pairs of upright ways. 8, those of each pair being located at,equal distances from and at opposite sides of the axis of the drum -3 for receivlng and guiding avermovable cross-heads -'9 having central verticall ielongated slots -l0- for receiving the ad acent portions of the burner 5-- and allowing vertical movement of the cross-heads without interference with said burner.

A pair ofsimilar centrally pivoted at end of the cross-heads one and the same horizontal axis with their branches extending forwardly and rearwardly in substantially parallel planes for receiving and supporting the corresponding ends of a pair of fabric covered/feeding rollers -12-- and -12'- These feeding rollers -12 and -12'- tically -11'- to the upper are journaledat their ends in suitable bearing's 13in the rock arms -11- substantially equal distances from and atopposite sides of the vertical plane of the axes of the pivots '11-' and heating drum to cooperate. with the upper surface of the heating drum in feeding the articles-to be ironed through the machine and simultaneously smoothing and ironing the same. The rollers 12 and 12\- are rotated in the same direction indicated by the an row in Fig. 3 and for this purpose,-are provided at one end with gears l4 meshing with an intermediate drive gear 15,

which in turn is journaled upon the central portion of the rock-.arm'-11 so that the gears will always remain in mesh in any position of rocking movement of the arms -11-'-' or vertical movement of the crossheads -9. v

The driving gear -15- is preferablysecured to the inner ends of a stud shaft -16-, which in turn is journaled in the rock arm --11,- and isprovided with a pair rock-arms --1l.- are i 9- to rock about having apertures of sprocket wheels -17- and -18-- of unequal size connected, respectively; by chains -*17"- and --18- to driving sprocket Wheels 19- and ---20v also of different size within a suitable gear housing -21c on the adjacent upper portion of the standard -'1-', the larger sprocket wheel 17 being'connected by chain r-17'- to the smallersprocket wheel as '19 while the smaller sprocket Wheel as -l8 on the shaft 16- "is connected to the larger sprocket wheel Within said gear housing, the object of these sprocket wheels of different sizes being to provide difi'erent speeds by which the feeding rollers may be operated.

are preferably loosely mounted upon a supporting shaft -22= carrying-an intermediate clutch collar 23 splined thereon andnormally in a neutral position between the sprocket wheels 19 and ,-2O but 30, the latter being also mounted upon the main supporting frame to form a unitary part of the machine as the source of power for rotating the rollers.

The cross-heads 9 carrying the rockarms -i-11-- and feeding rollers 12 and -12' are movable vertically along the guideways v 8,by means of a pedal lever adapted to be forced into engagement with V 31- extending rearwardly from the front' of the machine near the base thereof and having its rear end fulcrumed at '32- upon said frame and its front end provided with a pedal -33- by which the lever 31- may be depressed by the operator against the action of a retracting sprin -34, the intermediate portion of said lever being connected by a link -35 to a crank-arm 36, which is secured to a longitudinally extending shaft '-37-- having its ends journaled in suitable bearings in the upright standards -1- and provided with additional crank-arms 38-.

These crank-arms -38- are provided with longitudinally extending lugs-39- therethrough for receiving the adjacent ends of a pair of links -40- having their upper ends pivotally connected at '-41- to the lower ends of the crossheads -9'. The lower ends of the links '40 extend through and some distance beyond the lugs +39: and are preferably threaded for receiving nuts 42' and -43, the nuts -42 constituting shoul-- ders or abutments. for the lower ends of a parrot coil springs 4.4.- which encircle I '2 means 1,49o,see

the adjacent portions of the links and have their upper ends abutting against the underside of the lugs -39- toiform yielding connections between the links and crank-arms -38',/ and thereby to. allow the follers '12an d -12'- to be brought; into pressing coaction with the heating drum -*3 with a yielding pressure and also enables v the rollers to ad ust themselves to varying 1 thicknesses of/the articles which may be fed through the machine, while the tilting action of the arms 11 about their pivots -11' enables the rollers, -12- and 12--; to automatically adjust themselves 1 to different thicknesses of the same articles or of different articles.

Suitable means is provided for locking the pedal lever 31' and parts operated thereby in their pressing position, said e l 6+ pivoted at'47 to the lever '31-q and rovided with a pendant hook 48- niova 1e into and out of engagement with a rod (-49- on the main supporting frame 2 so that when the pedal lever is depressed,

the latch 48 will automatically interlock with a catch'49 to hold' the lever in its extreme thereby to hold -12'+ in their drum 3. j

The latch 46- is provided with a forward extension 50-'having a lug 51---1 projecting through an opening in the edal as 33- to :be engaged by the foot 0 the operator when desired to trip the catch 46, and thereby to release said lever and parts operated thereby, thus enabling the spring -34- to retract the lever and to raise the rollers -12- and '12 .out of pressingcoaction with drum '3', ready for the reception of the articles to be the rollers -12-- and pressing coacti'on with the 1roned. A v

The upper ends of the standards 1 are provided with forwardly projecting horizontal guides -52ffor supporting a forwardly and rearwardly movable table 53 upon which the articles to be ironed may be supported preparatory to feeding the same into'the machine or between the feeding rollers and heating rollera l The horizontal reciprocatory movement .of theltable 53 nized with the vertical reciprocatory move: ment of the cross=heads .9 and press rollers 12 and 12'-- carried thereby so that the table afterthe work has been properly straightened and smoothed thereon may feed the work to-the rollers ,simulta- 6 iieously with the depressionof the pressure rollers a d for this purpose, a pair of 11 right links or levers -54 are pivotally connected at their upper ends to the table- 53- and have their lower ends 'pivotally connected to the frame standards +1' at ring edge ofthe work consisting of, in this-lnstance; a latch.-

downward position and entire length of the is preferably synchro- 55 near the base of said frame the in termediate portions ofasaid links or levers 54- being connected by relatively short links -56- to a pair. of crank arms 57 on the rock-shaft -37- just at the inner sides of the standards '1 whereby when the rock-shaft -37 .is operated by the lever to force the pressinghrollers 12J and -12- into pressing coaction with the heating 'drum 3-, the table 53 with the work thereon will be advanced toward said drum to bring the leadinto engagement with the feeding roller 12, which by reason ofoits overhanging position relatively to the rear edge of the table -53- comes in direct' frictional contact with the upper surface of the work ,When the rollers are depressed to assure the feeding of the leading edge ofthe articles between the rollers. 5 That is, the front roller 12- is disposed A in a vertical plane some distance in front of the front face of the heating drum -3 while the table -53 is disposed in a horizontal plane partly belowthat of'the upper face of the heating drum and'directly belowthe lower face of the feeding roller -12 so that its upper surface carrying the work would be engaged by the periphery of the roller 12 when both of the feeding rollers are depressed to assure the frictional engagement and feeding of the work between the rolls for ironing purposes.

A guide-plate 58 is secured in the frame of the ma'chinebetween the upright standards 1 to extend the entire length of the heating drum and also forwardly and downwardly from the rear face thereof in spaced relation thereto to receive the leadingedges' of the ironed articles and to direct them forwardly within easy reaching distance of the operator at the frent of the machine. 4 Y

A stripper-plate 59 is also mounted withintlfe, machine and between the upright standards -1 to extend practically the heating drum 3 at the lower front side thereof. and is provided with a series of stripper fingers preferably of spring metal spring presse against the periphery of the drum for stripping any mental'ironing'roll 60- coaxial therewith but "external to the frame of the machine to cooperate with a vertically movable prem" head --61 at ,the upper side thereof for ironing relatively narrow articles, such as the-bands or marginal edges of OtllBIWISB,

'flat work, said press-head -'-61-- being 110 its ' made of metal having a smooth cylindri-r mounted on the outer end of a rock-arm 62- which is fulcrumed at 63- to the upper portion of the adjacent side or end of the machine toswing vertically lengthwise thereof or about an axis at right angles to that of the roller -12'- and heating drum 60-. 7

The pivot 63 preferably consists'of a -rock-shaft having a crank arm 64- connected by a link -65- to a supplemental pedal lever 66 Which is pivoted or ful- 'crumed-r at 67- to the base of the adjacent end of themaohine to rock verticallyagainst the action of the retracting spring 68-- 'which yieldingly holds the presshead-Gland its operating means in an elevated position, as shown in Fig. 1'.

The ironing drum 60 is preferably cal periphery, while the press-head '.61 is also made ofmetal and is provided with a heating chamber for receiving a gas burner which, in this instance; consists of the inner end of the rock-arm 62, the latter being. tubular and connected by a flexible hose or pipe 69- to source of gas supply not shown, the lower face of said press-head, 61 being concaved in cross-section to conform to the periphery of the roller K If desired, the supplemental drum ---60- may be covered with fabric to assist in frictionall feeding the articles against the concaved eated face of the press-head -61- when the latter is in res'sing position.

The operation brie y stated 1s ,as follows:

Assuming that the various parts of the machine are in their normal position with the table "-53 withdrawn from the rollers 12- and 3- and that the rollers 12- and 12'- are elevated away from the heating drum. Then, the operator first straightens the leading end of the article to be ironed upon the upper face of the table distance 53 with'said leadingedge alined with the rear edge of the table but a suflicirnt away from the rollers to prevent contactof the fingers therewith whereu" on the pedal lever 21- may be depresse to move the table 53 With the work thereon rearwardly toward the pressing rollers and to simultaneously bring the pressing rolls into pressing coaction with the'heating drum 3--, thereby causing the lower face of the roller -12- to engage the upper surface of the article on thetable 53- and to feed the same between the rollers .for ironing purposes, the lever 31 being then looked in its down position by the catch 746- to hold the table 53 and pressing rollers in operative position While the work is fed through the machine, the com pleted work being returned along the upper face of the u1de--'58- to the operator beneath the tab e 53-. L

a suitable and pressure rollers to return to their normal positions' t i In ironing relatively narrow articles, they are simply placed upon the upper face of the roller and-pressed'thereagainst by the depression of the press-head/,6 1 through they medium of the pedal lever 66-, said press-head and its supporting arm 62 being adjustable-lengthwise in a supporting-head and is held in its adjusted-position by a, set screw -71-, the object ofthis adjustment'being to enable' the operator to-use the outer end of the pressing surface of the press-head at any part along the length'of' the roller 60- particularl when pressing, the band or marginal e ges of certain articles.
