Original No. 1,536,771, dated May 5, 1925, Serial No. 587,493, filed September 11, 1922. Application for reissue filed September 11, 1926. Serial No. 134,902.

This invention relates toimprovements in ironing machines and has for its princlpal obj cct to provide a' machine of this character which is especially adapted for household use. v

A further object of the invention is to provide an ironing machine which is relatively small andcompact and in which the parts are so constructed and pivoted as to permit of its being folded, when not in use, to occupy a minimum amount of space.

. A still further object of the invention is to provide a, power driven machine having a plurality of rolls or mangles which may be heated by gas, steam, or other suitable medium, and which will be simple in construction, comparatively inexpensive to manufacture, and more efiicient in operation than those which have posed.

In the accompanying drawings in which like numerals designate like parts in all the views;.

Figure 1 is a front view of a machine made in accordance with the present invention, a portion of the head or housing being broken away to more clearly illustrate the interior construction, and the parts being shown in their operative positions;

Fig. 2 is a plan view of the parts shown in Fig. 1; V

Fig. 3 is a view similar to Fig. 1 illustrating the parts in their folded positions;

' Fig. 4 is "a side elevational view of the parts shown in Fig. 1, as seen from the left of the said figure; and

Fig. 5 is a side elevational view of the parts shown in Fig. 1 as seen from the right of the said figure.

-Referring to the said drawings, it will be seen that the machine comprises a frame" composed of the horizontal members 10 and the

upright members

11 and 12, the lower ends of the latter being secured in spaced relation Po the members 10, while their upper euds'are connected together .asiby bolts 13 forming a substantially triangular framework. The said members 10 are, provided with suitable rollers 14 whereby the device may be readily moved over the floor, as will,

be readily apparent.

The connections 13 serve as a pivot for supporting the. substantially 'trian ar shaped auxiliary supporting frame or ousheretofore been pro-,

ing 15, to whichis secured a suitable electric motor, or other driving means 16, whlch pulley 18 carried by a shaft 19 suitably journaled in the saidrhousing and carrying a worm 20 which meshes with a wormgear 21 rigidly mounted upona shaft 22 extending at right angles to the shaft 19, see Figs. 1 and 3.

The said shaft 22 carries a pinion 23, which meshes with a gear 24, mounted upon a shaft 25, journ aled in the said casing or housing in parallel relation to the shaft 22. The shaft 22 is further supported by means of an inclined bracing member or link 26, see Fig. 1, while the shaft 25 is likewise further supported by means of the bracing member or link 27.

The said shafts 22 and 25 respectively carry the rolls or

mangles

28 and 29, the former of which is preferably hollow, as indicated, to accommodate. one end of a pipe 30 which serves asa burner pipe for the combustion of gas or liquid fuel within the said roll 28. The said pipe may be supported by means of a bracket 31 secured to the bracing link 26 and the flow of the gaseous or liquidxzfuel therethrough, or of the steam where the latter is employed for heating purposes, may be controlled by means of the valve 32. The casing 15 may be provided with a door 33 to permit access to its interior for inspection, repair, or lubrication of the parts therein,

Suitably supported beneath the mangles or

rolls

28 and 29, as by the bracket 35 and the inverted U-shaped member 36, is a table 37, which is adapted to support the work during the ironing operation.

In order to control the pressure between the rolls 28 and 29', the latter of which is preferably covered with cloth or-other fabric, the link member 27.is connected to a collar 38 which is mounted upon the shaft 25 and which permits rotatiolnof the said shaft therein. The said link member 27 also p'ovided witha pin 39 which is adapted to.

engaged by the socket 40, see Fig. 3, of the upwardly extending rod 41', the lower endof which is connected to a lever or arm 42 rigid witha rock shaft 43, which also carries a treadle or lever 44, see Figs. 4 an 5.

It thus results that when-thetreadIe .or

is connected by means of a belt 17 to a arm 42 tothe upwardly extending rod lever 44 is depressed the motion is transmitted through the rock shaft 43 and lever 41 which exerts a pressure upon the pini 39, thereby causing the link member 27 and-collar 38 to tend to press the shaft 25 andiroll 29 upwardly, thus increasing the pressure of the said roll 29 against the roll 28, as will be readily apparent.

In order to permit a slight relative move ment between

therolls

28 and 29, the shaft 25 may be pivotally mounted in" the casing- 15, as at 45. It will be understood, however,-

that the relative movement is not great enough to disengage the gears 24 and 23 or to cause them to bind.

The treadle'44 is provided with a latch 46 having a plurality of notches or indentations 47 which are adapted to engage a pin 48 when it is desired to maintain a constantpressure between the

rolls

28 and 29. A spring 49 is rovided which tends to normally maintain the said notches out of en- I moved.

was a gagement with the saidpin and this spring 1 release the latch 46 Whenever a slight pressure is applied thereto and then re- As above stated it is one of the primary objects of this invention to provide a mechanism which may be folded up in order to occup a minimum amount ofspace, and, as hove described, the casing or husing is pivotally connected to the framework by the bolts 13. In order to limit the movement of the auxiliary frame 15 in one direction and maintain the parts in the operative positions illustrated in Figs. 1, 2, 4

- and 5, there is provideda stop abutment ll' on the base frame 11 against which a-portion of the auxiliary frame 15 may bear, there being also'provided a latch 50 mounted upon the upright members 11 and adapted'to engage a portion of the casing 15, as will be clear from Fig. 1.

When it is desired to fold up the machine, the catch 51-with which the table 37 is provided, is released. from the bracket 35, thereby permittin the said table to pivot upon its U-shape support 36 and to dro downwardly. The latch 50 is then release freeing the casing 15 and the mangles or rolls 28 and 29, as well as the burner pipe 30, for movement in aclockwise direction about i the pivot bolts 13 to the positions indicated in Fig. 3. It will of course be understood that a suitable flexible connection is provided between the burner pipe 30 and the source of the fuel supply in order that the said pipe may swing, as ust described.

It will thus beseen that this invention provides a relatively small and compact ironing machine suitable for household use and which may be folded up when not in use to occupy, a relatively small space.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore'it is not wished to be 'limitedto the above disclosure except as'may be required by the claims.
