PATENT OFFICE momma moms Original No. 1,868,806, dated July 26, 1932, Serial No. 167,314, February 10, 1927. Application for reissue April 7, 1934, Serial No. 719,617
and has for its objects the provision of a simplified-and improved design of small sized, com- Pact, open end machine'wherein the ironing...
pressure is produced by the same motor which operates the machine and which can readily be folded into a more compact position when not in use. Other objects of the invention are the production and improved construction of an open end ironing machine whereby an improved degree of rigidity is obtained, and whereby the ironing pressures are equalized at different points; the provision of new and improved means of supporting and manipulating the roll; the provision of an improved emergency release; the provision of improved mechanism whereby both the approach and the recession of the ironing parts are caused to occur in a uniform and orderly manner; the provision of a new and improved clutch; while further objects and advantages of the invention will become apparent as the description proceeds.
In the drawings accompanying and forming a part of this application Fig. 1 is a perspective view of an ironing machine embodying my invention; Fig. 2 is an elevation of the same machine, with the frame swung to vertical position and the bottom of the same being shown; Fig. 3is an end elevation of the apparatus mounted upon the frame with the cover-plate of the gear-housing removed; Fig. 4 is a detail view corresponding to the line 44 of Fig. 3 showing the emergency release; Fig. 5 is a. longitudinal sectional view of the roll and its operating mechanism corresponding to the line 5.5 of Fig. 3; Fig. 6 is a detail view of part of the roll mechanism shown in Fig. 5, the
roll itself being omitted; Figs. 7. and 8 are enlarged sectional views taken on the lines l1 and 8-8 of Figs. 5 and 6 looking in the direction of the arrows; Figs. 9 and 10 are sectional views of the clutch corresponding to the lines 9-9 and lllll respectively of Fig. 8; and Fig. 11 is a separated perspective view illustrating the different parts of the said clutch removed from each other.
My improved ironing machine comprises a rigid frame I onwhich are carried the shoe indicated generally at 2, the roll indicated generally at 3, the motor], and the mechanism for rotating the roll and for producing and relieving the ironing pressure, together with the levers with which such mechanism is controlled.
The shoe, as best shown in Fig. 8, includes the metallic plate 5 having the concave ironing face 6 and the end frames 1 which support the same.
44 Claims. (on. 38-59) These frames are provided with the front legs 8 and rear legs 9, the latter being .pivotally mounted at Ill upon lugs ll carried by the rear of the frame near its ends. The front legs have the feet l2 engaging the upper face of the frame and the depending hooks l3 adapted to extend through openings I 4 and to be engaged by catches ii to hold the iron in operative position. These catches 15 are slidably mounted in the guides it carried by the frame and are adapted to be moved longitudinally into or out of engagement with the hooks by means of the actuating lever ll, which extends transversely of the frame adjacent to its lower face and projects to where it can conveniently be moved by the operator. This lever is pivoted at I! to the frame and is articulated at opposite sides of its pivot to the catches l5l5, the arrangement being such that upon swinging the lever l1 against the tension of the spring It the catches l5 are simultaneously moved out of engagement with the hooks 13, thus enabling the shoe to rock to the position shown in Fig. 8 for cleaning, waxing, emergency, etc. A handle of heat insulating material is preferably provided to assist this movement or to restore the iron to working position.
Any desired heating agent can be employed, electricity being the agent herein provided for, a resistance heating element being located in a recess 2| formed in the rear face of the member 5, and backed up by insulating material 22, the latter being secured in place by clamps 23. I have shown the rear of this shoe as covered by 'a hollow sheet metal casing 24 which further shields the heating arrangement. I have also shown the shoeas provided with an upwardly projecting metal ball 25, supported in heat con- .shown in Fig. 3. Projecting from one face of this housing, with its axis spaced from and parallel to that of the concave face of the element 5, is a hub 28 in which is rigidly mounted, as by being shrunk therein, the horizontal cylindrical tube 29. Rigidly secured inside the housing is a bearing block 30 which carries the rigid tubular bearing sleeve 2| in which is rotatably journaled ducting relation with the member 5 by means of 1 housing 44 separate from and in the stub shaft 32. Rotatably journaled on the exterior of the tube 3| is the hub 33 of a sprocket wheel 34 connected by a driving chain 35 with the sprocket wheel 35 carried on a lay shaft 31 which also possesses a worm gear 38 meshing with a 1.3 a rigid bracket 41. Loosely surrounding the tube 29 is a cylindrical bearing ring 48 pivoted tothe bracket 41 on a horizontal axis 49 above and parallel to the shaft 29. Rigid with the fitting 45 is an arm 50 having at its free end a pivot 5| coaxial with the pivot 49, and carried thereby is a swinging arm 52 having at its free end a journal member 53 in which is joumaled the stub shaft 54 whose outer end is threaded at 55 for the reception of the roll. This roll comprises a 2:, cylindrical sheet metal casing 58 having at one end a head 51 formed with a threaded socket 58 for'the reception of the threads 55, and having at the. opposite end a circular ring 58 adapted to run upon the surface of the ring 48. The exterior of the roll is covered with padding material 8| of the usual or any suitable substance. The stub shaft 32 is operatively connected to the stub shaft 54 by means of the drive shaft 52 provided at opposite ends with the universal joints 53 and 3 54 respectively. The diameter of the tube 29 is so chosen intermediate the external diameter of the shaft 52 and the internal diameter of the ring 48 as to permit the bodily movement of the roll about the axes 49--5I asindicated in Fig. '1,
the shaft 52 moving from one position to another inside the tube corresponding with the movement of the roll outside said tube.
To accomplish this movement ofthe roll I have shown the following mechanism: Rigid with the ring 48 is a bracket 55 and rigid with the member 53 is a bracket 55 and to said brackets are secured the two ends of the rod 51. Projecting from the fitting 45 is an ear 58 in which is journaled a rock shaft 59 to the opposite ends of which are secured levers 18 and 1| respectively.
Carried by the fitting 45 is a projection 12 to which is pivoted a lever arm 13 similar to that at-15, and the free ends of the lever arms-19 and,
13 are connected by a rod 14 which is resiliently connected at opposite ends to the rod 51 by tension springs 15--15. In order to fix the distance between these rods and maintain a certain minimum'tension on the springs, suitable spacers are also preferably interposed between the two rods,
d such as the split metal tubes 15 which partially surround the springs 15. It will be seen that rocking the shaft 59 in one direction or the other will cause a movement of the rod 14 toward and from the shoe which movement will be com- 5 municated to the rod 51 by way of these springs.
To effect this rocking movement by the action of the power of the motor 4 I have shown the following mechanisms: the lay shaft 31' projects through the forward wall of the housing 7c 21 and is there provided with a clutch of the construction shown in Figs. 8, 9,10, and 11. Rigidly secured to the shaft so that it'may rotate therewith is a member 89 having'an internal cylindrical bearing face 8|, and rotatably mounted upon an extension 82 of said shaft concentric with the V with the surface 8|.
surface 8| is ametal disk 83 havinga cylindrical surface 84 concentric with and spaced from the surface 8|. Formed in the disk 83 transversely of its surface is a rectangular notch 85 in which.
is mounted the rounded inner end 85 of a rocker whose squared outer end 81 extends into the space between the surfaces 8| and 84. The remainder of the space between thesemembers is taken up by a couple of arcua-te friction members 8888 which are preferably mere semi-circular metal rings of such size as to fit freely into the space defined thereby. Onev of these friction members is provided with an ear 89 projecting laterally beyond the surface 8| where it is provided with a radial pin 9|I'which projectsbeyond the periphery of the clutch. In order to render the action of the clutch more uniform and certain I preferably interpose a small spring 9| between the members 88-88, and I also preferably interpose between these ends,-and surrounding the spring, a hollow spacing block 92. This spring, when used at all, should be very weak since its purpose is merely to create a very small amount of friction; and the block 92 is used primarily to facilitate the construction of the clutch by enabling the use of blocks of different widths to compensate for variations in the length of the members 88-88. So far as the operation of the clutch. is concerned the block is not necessary, nor is the spring of any advantage further than to make certain the operation of the device as will hereafter be shown.
To the outer face of the disk 83 I secure a metal plate 95 which preferably covers the entire face of the clutch excepting at the point 95 where it is notched for the free passage of the ear 89. Carried by the plate 95 is a pin 91 to which is articulated the connecting rod 98 whose opposite end is articulated to the free end of the lever 1|. With this arrangement the roll will be advanced and retracted every revolution of the plate 95, and it only remains to provide means to arrest this rotation and hold the device stationary at the desired positions.
For this purpose I provide a yoke having two upstanding branched arms I|I|I|ll| terminating in fingers I52 one at each side of the clutch.
This yoke is mounted for pivotal movement upon a horizontal transverse rod I03v and is provided with a dependingoperating lever I84 extending below the frame where it is connected to the link I95 which in turn is connected to the lever I95 pivoted to the frame at I81 and terminating in the depending pad Hi8- for engagement by the operator's knee. This yoke is normally held by the coil spring I99 in a position so that one of its fingers will engage the pin'98.
The operation of the clutch is as follows: the shaft 31 and clutch member rotate continuously; if the yoke member be displaced or removed, the initial friction of the surface 8| against the members 8888 tends to displace the latter very slightly relative to the-disk 83, and this movement inclines the rocker which thereupon wedges the members 88-88 more widely apart and into strong driving engagement to interpose one of its fingers in the path of the pin 98, the rotation of the friction member is instantlyarrested, which permits'the rocker 88 to straighten up, which reduces the friction between the members 80 and 88 to the very'small amount caused by the spring 9| or its equivalent. time the yoke is displaced this same cycle of events takes place, but with this difference, that If now the yoke be moved Each overrun the mechanism, the key is inclined to theopposite direction and the receding movement is restrained. The purpose of the spring III is merely to insure the existence of sufflcient initial friction to start the inclination of the rocker; and the block 92 or its equivalent is desirable merely because it is necessary that the driving engagement of the friction members and outer drum be produced positively and without any undue inclination of the rocker. When properly made and adjusted, a clutch capable of transmitting a substantial load can be arrested and held stationary by a very gentle pressure on the pin 90.
. fingers, arranged at any desired position about the clutch, each finger accordingly corresponding to a diiferent position of rest. In the present "embodiment I have illustrated a yoke having two fingers so located that in one position the mechanism will be-arrested with the roller advanced towards the shoe as illustrated in Fig. 8, at which time it is preferable that the pin 91 stand just beyond the dead center (as reckoned from the free end of the arm 'II), the opposite position of rest being approximately 180 therefrom at which time the roll is retracted from the shoe by its fullest extent.
It is also desirable that the roll should be rotated only while in contact with the shoe, and
should stand still at other times, thereby facilitating the application thereto of the articles to be ironed. To this end I have provided the mechanism shown in Figs. 3 and wherein one face of the hub 33 is provided with clutch teeth III cooperating with similar teeth formed on the face of a clutch spool III 'slidably splined to the exterior of a tube II2 pinned to the shaft 32 at II3. Cooperating with this spool is a shifting.
lever H4 pivoted to a suitable cross bar H5, and normally held in engaging position by a suitable spring IIB. Slidably mounted in the housing 21 is a rod I", one of whose ends is operatively secured to the lever III by the arm H8. The opposite end of the rod Ill projects close to the clutch member 30 and the plate 95 is provided at one point with an overhanging camiaced flange I20, adapted at the proper phase ofrotation to press against the rod III to disengage the clutch III against the tension of the spring Hi. It is also desirable in some cases, as when such a machine is to be used for pressing clothing, that the roll shall not be turned even when brought into contact with the shoe and to effect this I provide a suitable cam shaft I2I actuated by a handle I22 and having a cam portion I23 adapted when turned in one position to allow engagement of the clutch I II, and when turned in the opposite direction to prevent such engagement. 3
When electrical heat is employed the conductor wires are brought into the shoe 2 by way of the flexible conduit I25. The operation of the heater and motor are controlled byindependent switches I26-I2'| respectively carried by the frame in a convenient location, a pilot light I28 being preferably employed to indicate when the shoe is being heated.
For the purpose of mounting the frame I so that it may be swung to vertical position and occupy less/floor space I have provided a single pivot located substantially at the center of gravity of said frame and the mechanism carried thereby. Accordingly the device is substantially balanced at all times, is free from upsetting, and exhibits no lack of stability even though the pivot be not clamped. As such pivot I have shown a screw I30 threaded into the lug I3I extending upwardly from the rear of the frame and furnished with a handle I32 by which it may be tightened.
