MANGLE.

Specification of Letters Patent.

Patented Apr. 22, 1913,

To all whom it may concern:

Be it known that we, VACLAV KRAL, FRANK M. VACHA, and VRATIsLAv CAP, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Mangles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a class of devices known as mangles or devices for easily and rapidly smoothing out and pressing that class of laundried articles known as flat work, and has for its object the production of a device of this class which, in simplicity, durability, ease of operation, and convertibility shall be particularly adapted for domestic use. It is a well known fact that many house-wives would employ a machine of this character but for the room which it necessarily occupies when not in use.

Among the objects of this invention is the provision of a machine of this type, which, when not performing the fundamental purpose of its existence, can be converted into a very strong and satisfactory table, all the machine parts being housed within the area of the table top, thus permitting its use for some purpose at all times.

Other advantages of this invention relate to the details of construction and arrangement of parts whereby the above named objects are obtained.

In thedrawings accompanying and forming part of this specification, we have illustrated one embodiment of our invention, the same being that embodiment in which we prefer to use the same, although it will be understood that this showing is illustrative merely, and that we do not propose to limit ourselves to the exact features of construction and arrangement shown therein.

In these drawings; Figure 1 is a front elevation of the complete machine; Fig. 2 a side elevation of the same showing it as adjusted for use as a mangle, the dotted lines indicating the position thereof when ar ranged for use as a table; Fig. 3 is a detail view of a portion of the upper end of the right hand standard shown in Fig. 1, the

gearing being omitted; Fig. 1 a plan view of the machine parts being broken away; and Figs. 5 and 6 are detail views illustrating the method of securing the fly wheel to its shaft.

Describing the parts by reference characters, 1 and 1 indicate respectively the right and left hand upright standards which support the operating parts of our improved mangle, said standards being preferably forked at their lower ends to provide the branches 2-2 as shown in Fig. 2. The upper end of these standards are formed with vertical slots 3, and the sides of said standards are formed with brackets 44 and 5-5, the tops of the latter brackets being substantially flush with the top of the standards, and the brackets 4ct being of greater lateral extent than the brackets 55 and disposed a considerable distance therebelow. The standards 1 and 1 are securely fastened together at their lower ends by means of stay rods 6-6 preferably secured to the ends of the branches and at their upper ends by a narrow cross piece 7, preferably of wood, and bridging the upper ends of the slots 8. Intermediately between their ends these standards are also preferably connected together by means of a yoke 8 which may convenientlybe formed of cast iron, the function of which will be later described.

The lower end of the slot 3 is preferably reduced as at 10 to form a bearing for the shaft 11 of the lower roller 12 of the mangle, said shaft 11 carrying at its farther end a gear wheel 13. Slidably mounted in each of the slots 3 above the reduced portion thereof is a bearing block 14 in which is journaled the shaft 15 which carries the upper roll 16 of the mangle and is provided at its farther end with a gear wheel 17 similar to and meshing with the gear wheel 13. The rollers 12 and 16 may be made of hard wood or other suitable material, and their ends are spaced a short distance inward from the standards 1 and 1 as shown in Fig. 1. The upper surfaces of the blocks 14 are formed at the point inside the standards 1 and 1 with shallow grooves as illustrated in Fig. 1, and in these grooves are fitted stirrups 2020 having depending shanks 2l21. As illustrated in Fig. 2 the shank portion of each stirrup comprises a palr of straight one of said rods being formed with a terminal eye 21, and the other being formed wlth a rightangularly turned end 21 adapted to enter said eye and be retained therein by a cotter pin. Secured to said stirrup shanks, as by being looped about the portion 21 thereof, is a semi-elliptic leaf parallel rods 21 and 21 from, the upper surface thereof being slightly below the upper surface of the roller 12 as shown in Figs. 1 .and 3. The width of the bracket 4 is slightly greater than that of the board 25 whereby a narrow shoulder is left at each side of the machine, and said shoul- 'der is formed with a notch 26. The brackets 5-5 also extend laterally a greater distance than the cross piece 7 and are likewise formed with notches as shown in Fig. 3. These shoulders are for the reception of the feeding and receiving platforms 27-27. each of "which consists of a smooth surfaced board .or plate of the same thickness and length as the cross piece 7 and having at their inner edges the down-turned hooks 28 adapted to engage the notches 26, and the notches in the brackets 5. Pivotally secured to lugs or brackets 29 carried near the outer edges of these platforms are braces 30, the inner ends of which are pivoted to the frame standards 1 and 1 at 31. IVhen the machine is arranged for operation, the plat forms 27 27 are supported by the brackets 4 as illustrated in full lines in Figs. 2 and 3. When it is no longer desired to employ the machine as a mangle, the platforms are disconnected from the brackets 4 and attached to the brackets 5 as illustrated in dotted lines in Figs. 2 and 3. The length of the braces 30 and theirpoint of attachment is such that they will support the platforms v27 truly horizontal both in operative and inoperative positions.

For operating the rollers we employ the mechanism now to be described. Formed on the sides of the standard 1 between the brackets 4 and 5 are other brackets 35 and 36, the bracket 35 being formed at its outer end .withan outwardly projecting boss 37 carrying a stud 38. Journaled on this stud is a fly wheel 39 having secured immediately inside the hub thereof a pinion 40. Carried by thebracket 36 is a stud 41 on which is sleeved a gear wheel 42 meshing with the pinion 4:0 and carrying on its inner face a smaller pinion 43, which in turn meshes with a gear wheel 4:4: secured to the-end of the shaft 11, above mentioned. In order to permit the removal of the fly wheel'when the device is being used as a table, we prefer to secure it to the stud 38 bythe expedient shown in Figs. 5 and 6. According to this expedient the end of the stud 38 is formed with a groove 50,. and to the hub 39 of the wheel is pivoted a latch 51 having a'curved part'52 adapted to enter-said groove. This latch is maintained in engagement with the groove by means of a spring 53 and can easily be detached therefrom upon occasion, thus permitting the ready removal of the fly-wheel. lVhen not in use, the fly wheel can be conveniently hung upon a hook 55 secured to one of the standards of the machine as shown in dotted lines in Figs. 1 and 2.

By referring to Fig. 2 it will be seen that the width of the cross'piecesv 25 is such as to bringtheir outer edges beyond the ed es of the gear train. It is, therefore, possible .to make the .platforms 27 of the same length as the cross piece 7, thus producing a table top of perfectly regular shape and one that overhangs all of theworking parts of" the machine. It will also be seen that the machine can be dismantledwithgreat facility 7 wheels for driving said rollers located -out side of said standards, a cross piece connecting the upper ends of said standards and bridging the slots therein, said cross piece being of sufficient length to cover the gears at each side of-said standards, .cross'pieces connecting said standards at each side of said rollers, the upper surfaces of said last cross. pieces being not higher than thepoint of contact of said rollers, and the outer edges of-said last cross pieces projecting outwardly from said standards beyond said gears, platform members: havingtheir length substantially equal to the length of said first cross piece, means for securing the inner edges ofisaidplatform members at the sides of either said first mentioned or said last -mentioned cross pieces, and braces secured to said standards and to said platform members and. adaptedto'maintain the latter substantially horizontal in both of the said positions of adjustment.

.2. In a device ofthecharacter described, in combination, a pair of up-right standards, a pair of horizontal rollers journaled in said standards, gearing outside of said standards and adapted forthe operation of said rollers,

a cross plece connecting the upper .ends of sald standards, the length of such cross plece bemg sulficlent'to entirelycoversald .gears, shoulders carried by [said standards at each sideof said cross piece,. rother cross pieces connecting said standards at each side of said rollers, the upper surfaces thereof being not higher than the meeting point of said rollers, and the length of such last-mentioned cross pieces being such as to permit them to fit inside of said gears, shoulders at the outer sides of said last mentioned cross pieces, platform members adapted to rest upon either of said shoulders with their top surfaces in substantial alinement with the upper surface of the adjacent cross piece, the length of said platform being substantially equal to that of said first mentioned cross piece, and braces connected to said standards and to said plat- 5 form members, said braces being adapted to maintain said platforms substantially horizontal when in contact with either of said shoulders.

In testimony whereof, we hereunto affix 20 our signatures in the presence of two wit- Mrs. H. L. MACH, HENRY L. MACH.
