IRONING-MACHINE.

nooaetaf To all whom 'it maypconcem;

Be it known' that' L-AxnnR. GUSTAFSON, a citizen of the-'United"States,-,and residing at Chicago, thelcounty of Cook and State of IlllIlOlS, havefinvented ai new and useful Improvement in Ironing Machines, of which the following a complete specification. l i 5 a The main objects of this invention are to provide an improved ironing; machine for laundry purposes; to provide an improved ironing machine having improved mechanism for regulating the pressure of the ironironing machine embodied in this invention.

Fig. 2 is an end elevation of the other end of the machine. Fig. 3 is a front elevation of the machine, with parts removed. Fig. 4 is an enlarged, fragmentary end elevation of the ironing rollers and the means for adjusting the same. Fig. 5 is an enlarged, fragmentary front elevation of the ironing rollers and the means for adjusting the upper rollers with respect to the lower roller. Fig. 6 is a horizontal section of one of the channel guides and guide arms.

In the construction shown, a suitable frame is provided which comprises end members 1 which are rigidly secured together by means of tie orfbrace rods 2. Rigidly secured on the tops of the end members law the bearing

members

3 and 4 on which the operative mechanism is mounted. The bearing

members

3 and 4 are provided with

bearings

5 and 6 in which is journaled the heating roller 7, which is provided at its ends with trunnions 8 and 9 mounted in said bearings. The heating roller 7 is hollow and is provided with ventilating apertures 10 in one end. A burner 11, comprising a perforated pipe, rigidly secured in a bracket 12 carrled on the member 3, and extends through the trunnion 8 into the Specification of Letters Patent.

Patented Oct. 3, 1911.

" Application filed March 10, 1911. Serial No. 613,590.

roller 7 The inner end of the burner is supported in a bearing 13 at the end of the roller, and the outer end of'the burner is connected with a pipe 14 leading from a'gas supply, and provided with suitable cocks 15 and 16 which are adapted to control the amount of gas entering the burner.

Extending upwardly and rearwardly from the

bearings

5 and 6 are the channel shaped guides 17, and slidably mounted in said guides is the carriage 18 for the

compression rollers

19 and 20. Said carriage comprises end pieces 21, each of which is provided with a centrally disposed, downwardly directed guide arm 22 which is slidably mountedin the adjacent guide 17 and is provided with a slot 23 through which a stop bolt 24 projects. Said bolts are rigidly secured in the guides 17 and act to limit the movement of the carriage 18, and to prevent said carriage from being displaced from the bearing members 3 and 4:. EX- tending downwardly and laterally from each of the end pieces are arms 25 in which tie rods 26 are secured to connect the end pieces together and cause them to move in unison. The

compression rollers

19 and 20 are journaled respectively in the rear and front sides of the carriage 18 in bearings 27 in the end pieces 21, and are each covered with canvas or other suitable material v28. 7

Extending outwardly from the upper end of each guide 17 is an apertured lug 29', and extending upwardly on each end piece 21 is a bracket 30 having an outwardly directed apertured lug 31. At each end of the carriage is an adjusting shaft or bolt 32 which is rigidlysecured at its lower end in the lug 29, and at its upper end extends through and is loosely mounted in the lug 31. Carried on said shafts between the

lugs

29 and 31 are coiled springs 33 which normally act to hold the carriage 18 in an elevated position with the compression rollers out of contact with the heating roller. The upper end ofeach shaft 32 is screwthreaded, and having threaded engagement thereon is a hand wheel 34 which when turned into engagement with the lug 31 acts to force the carriage downwardly and increase the tension of the springs 33.

On the inner face of each end piece 21 is a ledge 35 having apertures therethrough through which project pins 36 which carry at their upper ends a plate 37 Mounted on said pins 36 between the ledges and the plates 37 are coiled springs 38 at each end of the machine, whose combined strength is greater than that of the springs 33.

Extending upwardly and forwardly from the rear sides of the bearing

members

3 and 4 to a point above the plates 37 are arms 39, which carry a rod 40 at their upper ends. Journaled on said rod 40 above the plates 37 are the cam levers 4l-which have cams 42 at their lower ends which bear on the plates 37. The upper ends of said levers are connected by an operating bar 43 by means of which the levers may be simultaneously operated. Each lever 41 is provided with a stop-block 44 on its outer side, which blocks are adapted to rest on the arms 39 when the levers are at their rearward limit of movement, to limit said movement in that direction. For the purpose of operating said rollers a drive shaft 45 is journaled in bearin'gs 46 carried on a bracket 47 at one end of the machine. A worm .48 is rigidly secured on said shaft and meshes with a worm gear .49which is carried on a stud shaft 50 journaled on the bearing member 4. Rigidly secured on the shaft 50 is a pinion 51 which meshes with a gear 52 on the trunnion 9 of 1 front of the machine is the work table 56 the roller 7. The

rollers

19 and 20 are provided at their ends with bearing trunnions 53 which are journaled in the bearings 27, and rigidly secured on the trunnions at the end of the rollers adjacent to the gear 52 are gears 54 which are adapted to mesh with the gear 52 when the carriage is lowered. As shown, the shaft 45 is provided with a pulley 55 adapted to be driven from any suitable source of power.

Supported on the

members

3 and 4 at the which partially overlaps and is on a level with the top of the roller 7. The work is supported on said table while'being fed to the rollers. Extending forwardly at each end of the machine, and slightly below the table 56 is a work supporting rod 57, which 1s preferably formed of wood. Upon one of sa1d rods the articles to be operated upon may be hung, and upon the other the finished work may be hung.

A tray 58, formed of sheet iron or other suitable material, is supported between the frames 1 on the upper rods 2, and at the rear of the machine the tray extends u wardly to a' point behind the rollers. T e upper edge of the tray is turned rearwardly to provide a hook 59 which engages over the rod 60 supported on the arms 39. This method of mounting the tray makes it re- .movable so that it may be kept clean.

The operation of the construction shown is as follows: The operator lights the burner and when the heating roller has become sufficiently heated power is applied to the pulley 55 to set the heating roller in motion. The operator then pulls the bar 43 forwardly thereby causlng the cam levers 41 to compress the springs 38 and force the carriage downwardly against the tension of the sprlngs 33 until the gears 54 are in mesh with the car 52. I p

The 010 hes tobe ironed are hung upon one of the rods 57 in convenient position for the operator to get and feed into the machine. The articles after passing between the rollers drop into the tray 58 where the operator may remove them from the front of the machine and hang them on the other rod 57.

Obviously the ironing operation may be instantly stopped by throwing the levers 41 rearwardly thereby releasing the tension of the springs 38 and permitting the springs 33 to force the carriage upwardly and throw the gears out. of mesh. By adjusting the hand wheels34 on the shafts 32 the pressure of the

compression rollers

19 and 20 may be regulated.

While I have shown and described but one embodiment of the invention, it Will be understood that many details of the construction shown may be varied or omitted without departing from the scope of the claims.
