HERMANN HILL, OF DETROIT, MICHIGAN, ASSIGNOR TO SYRACUSE WASHING MACHINE CORPORATION, F SYRAOUSE, NEW YORK, .A CORPORATION OF DELAWARE VASHOE MOUNTING FOR IRONING MACHINES Application filed August'29, 1928. Serial No. 302,767.
This invention relates to a power-driven ironing machine andas illustrated in t-he drawings, the ironer is adapt-ed for the use of electricity.
. In an electrically operated ironing machine, the ironer or as Iprefer to term it, the shoe, which cooperates with the roll, is mounted on a rockerarm which is adapted to be moved by an operating shaft driven by some part of the mechanism of the machine, which mechanism is in turn operated by an electric motor.
' It is the principal object of my invention to provide new and improved meansfor mounting the shoe on the rocker arm whereby other ancillary objects are attained, which will be brought out in the descriptive matter to follow.
Since the -mechanism for operating the roll and the shaft which manipulates the shoe maybe variedl over wide limits, I have therefore only shown the mechanism relating to the shoe mounting per se. In the drawings, v
Figure 1 is a sectional View through the ironing shoe and mounting means for carrying and operating theshoe. This section is taken on the line 1-1 of Figure 2.
Figure 2 is a `view looking at the v shoe and mounting means from the right of Figure 1, the shoe and operating shaft being cutoff at one end.
Figure 3 is a plan view of the attachment plate and bracket which are attached directly to the shoe.
Figure 4 is a part sectional and elevational view on the line 4-4of Figure 3.
Referring now to the details wherein like numbers refer to corresponding parts lin the drawings, 1 illustrates the roll of the ironing machine. 2 is an operating shaft driven by some part of the ironing` machinemechanism that is operated by an electric motor. Securely attached to the shaft 2 as by a key 3 and set screw 4, is a rocker arm composed of two pieces 5 and 6, the ypiece 6 being pivoted on the piece 5 by means of a pivot pin 7 which is supported by the arms 8 and 9 which extend upward- .ly from the'piece 5. As will be seen from `tension will be permanent andisubstantially `independent of the mechanism which operates the shaft 2.
the clamps 24 and 25 to be drawn down se- Figures 1 and 2, the piece 6 is channelshaped having the web of the channel terminating in a lug 10 which carries adjusting screw '11 for the purpose of adjusting the position of the piece 6 about the pivot pin The upper end of the flanges of the piece 6, `is provided with holes and through these holes, passes a pivot pin 12. The pivot pin 12 carries a bracket 13, the end of which is positioned ,between the two flanges of the piece 6.
The piece 5 of the rocker arm is prol vided with a pocket or 'recess 14, within which is positioned a vcantilever spring which as illustrated, is made up of four leaves, 15, 16, 17, and 18, the longest leaf, 18 resting against the end of the bracket 13.- The leaves of this cantilever spring are securely held in the pocket or recess 14 in any satisfactory manner as by a set screw 19. f
By adjusting the screw 1-1,the desired amount oftension can be stored in the cantileverspring, and it will be clear that this The bracket 13 is attached to a multiple Hat-leaf spring 20 by meansof a heavy cap screw 21. The spring 20 is positioned in a pocket 22 of a plate 23, being held in the pocket' 22 by means of clamps 24 and 425` which are held to plate 23 by screws 26 and 27. The plate 23 is preferably made of a casting and in order to save doing machine work on the pocket 22, I prefer to use ais ' spacers 28 and 29 between the clamps 24 and 25 and lthe plate 23, which spacers take up variations in the casting and also allow 90 curely without actually clamping against the ends of the spring 20 which is left to move freely in the pocket, there bein side clearances 30 and31, as shown in igure y 3. This method of mounting the bracket 13, allowsthe plate 23 and the entire shoe 32 fastened to the plate, to have a certain endwise, up-and-down, as well as a slightly rotary motion, in order that theshoe 32 may adJust itself to the contour of the roll 10 l 2) to receive the flatsurface of the plate 23.
The shoe 32 carries the heating elements 37 and 38 which are of a special design, but since they Jform no part ot the present invention, will not be further described herein.
However, to direct the heat toward that part of the shoe in contact with the roll 1, a strip ot asbestos 39 is used between the metallic member 33 and the heating units 37 and 38.
. A cover 48 is 'fastened by bolts 49 to the shoe 32, a strip of asbestos being used to prevent the heat from radiating from the backside of the shoe. It is to be understood that the metallic member 33 is fastened in any satisfactory manner to the shoe 32, as by bolts 51 (only one being shown). f
An important feature of my invention is the method of rtransmitting the lapplying :torce to the shoe 32. This is accomplished in the following manner:
The backside of the plate 23 is provided with a slight recess 40, and in this recess. is positioned a st-rip 41, preferably of cold rolled steel which has formed in `it a shallow cup 42 to fit over the rounded head of the cap screw 21. In the metallic member 33 there I is formed( a cup 43corresp`onding in contour to the cup 42, one cup being. nested into the other withcpreyferably a piece of asbestos 44 interposed to prevent as much as possible`the heat' from coming out ofL the rear part of the` shoe.
This construction and association of the parts 21, 41, 42, and 43, together with the spring 20, provides a swiveling or equalizing connection between the shoe 32 and the rocker arm that allows the shoe to take up a perfect alignment on the roll A1. However, to get the first adjustment between the shoe 32 and the roll 1 generally correct. a set screw 45 is carried by the piece 6 and is adapted to engage a projection 46 on the bracket 13.l but after this adjustment has once been made, the iiexible union of the shoe and the bracket 1.3 as justy dey scribed, will take care of all oit the other variations, includyin'g thickness and irregularity of the workpassed between the roll 1 and the shoe 32.
By providing the adjustment between the pieces 5 and 6 bv means of the screw 11 as previously described, a very desirable and important obj ect is attained. for by this arrangement, at the time when the shoe reaches the roll due to the'turning of the operating shaft 2. the cantilever spring is under full tension which is onlyslightly increased when the` operating mechanism Vof the machine. which may be an eccentric device, has reached the .i limit of its movement for applying the shoe to the roll. When the shoe is in full contact with the roll, the set screw 11 will be free from contact with the piece 5, as indicated by the space 47, and pressure is transmitted from the rocker arm'to the bracket 13 and thei head of the cap screw 21 to the swivel joint as described.
Since this rocker armiis fully'exposed ont the machine, this adjustment may be quickly and easily made and the clearance observed as above indicated, proves that the iron is in full pressure contact with the roll.
While I have shown the cantilever spring as being made up of four leaves of dierent lengths, it is obvious that the number and length of these springs may be varied to suit the condition. It is also obvious that the spring 2O may be made up of a more or less number of these springs than the four shown in the drawings, and likewise, other details may be varied without departing from the spirit of my invention as limited by the scope of the appended claims. I
Having thus described my invention, what I claim is:
