SWITCH origial Filed June 14. 192e Patented. Jan. 28, `1930 UNITED STATI-:s
PATENT OFFICE CARL F. ANDERSON, OF BROOKFIELD, AND RUDOLPH W. JANDA, F BERWYN, ILL-L N OIS, ASSIGNORS TO CONLON CORPORATION, OF CICERO, ILLINOIS, A CORPORATION OF ILLINOIS SWITCH Original application iiled .Tune 14, 1926, Serial No. 115,820. Divided and this application iiled November 4, 1926. Serial No. 146,106.
Our present invention has to do with electrical switch mechanism and more particularly to switch locking mechanismdesigned especially for use in conjunction with our novel ironing machine disclosed in our co-pending patent application, Serial N o.
115,820, filed June 14, 1926.
It is necessary in the operation of an ironing machine, including a revolvable roll and a pressing shoe movable to and from the roll,
that the switch controlling the motor for actuating the roll be locked in its on position when the shoe is in contact with the roll so as to prevent the shoe from burning the padding on the roll. That is to say, when the roll is engaged by the shoe the roll should rotate continuously until the shoe is moved out of cooperation therewith.
We propose to provide a novel switch device including locking mechanism adapted to be operated automatically by the ironing machine mechanism to lock the motor switch in its on position when the shoe is in contact with the roll.
It should be noted that the present application covers subject matter divided out of our previously mentioned co-pending patent application.
Other objects and advantages of our invention will more fully appear from the following detail description taken in connection with the accompanying drawing, which illustrates one embodiment thereof and, in which:
Figure 1 is a plan view of a switch device embodying the features of our invention;
Figure 2 is a sectional view taken Qn substantially the line 2 2 of Figure 1, looking upwardly;
Figure 3 is a sectional view taken on the line 3 3 of Figure 2, looking in the direction indicated by the arrows;
Figure 4 is a view partly in section similar to the View shown in Figure 1 with the top of the cover removed from the device; and
Figure 5 is a perspective view of the lockl ing element employed in 'the switch.
Referring now to the drawing in detail, in which like reference numerals designate 50 similar parts throughout the several views, 10
denotes generally a casing for housing the switch mechanism. This casing is preferably made of sheet metal and comprises a top 11 and a pair of sides 12 and 13.
Positioned within the casing 10 and beloW the cover 11 is the switch mechanism comprising a pair of switch units 14 and 15. The unit 14 comprises a base 16 which may be made of porcelain, and a laterally extending finger or operating member 17. Similarly, the unit .15 comprises a porcelain base 18 and an operating finger 19. The two porcelain bases 16 and 18 serve to enclose the switch mechanism, which may be of any conventional construction.`
The base 16 of unit 14 has connected thereto a pair of laterally extending flanges 2O and 21 (Figure 4) which are securely fastened to the top 'or cover 11 of casing 10 by means of bolts 22. Also, base 18 of the switch unit 15 is equipped with a pair of laterally extending iianges 23 and 24. These fianges are fastened to the top 11 of casing 10 by means of bolts 25. Thus it will be seen that both of the switch units 14 and 15 are rigidly fastened to the casing 10'.
Referring to Figure 4, it will be observed that the two switch fingers 17 and 19 have a substantially square cross section. These two fingers 17 and 19 project upwardly through rectangular apertures or openings 26 and 27 formed in the top 11 of the casing 10. Each of these apertures is approximately two and one-half to three times as long as it is wide, so as to permit the finger associated therewith to be reciprocated. Moreover, these apertures 26 and 27 serve to enable a person to ascertain whether the switches are in their on or 0E positions.
It will be observed from Figure l4 that the finger 17 extends upwardly through a substantially square aperture in a reciprocable indicating slip 29. This slip or member 29 has printed thereon the term Of and On. Similarly, the finger 19 extends upwardly though a square aperture inan indicating slip or member 30 having printed thereon the terms Off and On Each of these slips is adapted to be reciprocated with its associated nger and serves to indicate the conconstruction. The'electrical plug 31 serves to enable the/electrical circuit to be connected to the two switch units 14 and 15. This plug is adapted to be engaged by a suitable electric socket. Also, the casing 10 is provided with a closure member or bottom 32 suitably fastened to the sides 12 and 13. Y
Positioned between the top 11 of casing 10 and the indicating plate 30 associated with switch unit 15, is a lockingelement 35 which is illustrated .in perspective in Figure 5. The element referably comprises a top 36 and a pair o integral sides 37 and 38. In other words, ,the locking element 35 is channel shaped. The top 36 of this element is provided with a tapered-like' slot or aperture 40 through which the finger 19 of switch unit 15 rojects. One end of this aperture 40 is de ned by a relatively'square .or shoulder portion 41 adapted to abut the side of the switch finger 19. It will be evident from Figures 3 and 4 that the sides 37 and 38 of this locking element extend downwardly over the sides ofthe associated switch base 18. In fact, the channel-like locking element 35 is adapted to be reciprocated on top of the switch base 18.
One end of the side 38 of the lock element 35 is equipped with an extension 44 having an aperture 4 3 through which extends a pivot pin or bolt 42. The shank of the bolt 42 also projects through an elongated aperture 45 in one end 46 of a lever 47 (Figure 2). In other words, the extension 44 is pivotally attached to one end of the lever 47.
Now lever 47 extends downwardly through an aperture 48 in the bottom closure member 32. The lower end 49 of this lever 47 is bent laterally in a direction away from the side 13, as shown in Figure 3. The extremity of this leg 49 of lever 47 is formed into a relatively liat portion 50 disposed at an angle to the leg 49. Also, lever 47 is pivoted between its ends by means of a bolt 51 to a lug 52 (Figure .3) formed integral with the side 13. In fact, the lug 52 is punched from the side 13.
The operation of our device is briefly as follows:
The iiat portion 50 of the lever 47 is adapted to'be engaged by a part of the mechanism, the operation of which is to be controlled by the switch unit 15. In Figure 1, we have illustrated the portion 50 as being engaged by one end of a rod 60, which may be part of an ironing machine such as that disclosed in our co-pending patent applica,-
tion. This rod 60, as disclosed in the copending application, serves to control the operation ofthe ironing roll and to prevent the stopping of the revolution of the roll when the ironing shoe is in engagement therewith. In other words, the element 60 is adapted to operate .the locking element 35 to prevent the operation of the switch member 19 when the shoe is in engagement with the ironing roll.
Assuming that the 'switch member 19 is in its on position, and that the motor is operatively connected to the ironing roll of the ironing machine, upon the'movement of the shoe into engagement with the ironing roll the pin 60 will be actuated to move the locking element 35. That is to say, the upper end of the lever 47 will move the member or element 35 over the on indication of the indicating card 42 associated with switch unit 15. In fact, the top 36 of element 35 will be moved in a direction towards the pivot bolt 42 until the shoulder 41 engages the side of the switch iinger 19, thus locking this member against operation and preventing the motor from being turned oifbyl the switch.
Afterthe'shoe has been moved out of -cooperation with the ironingroll ofthe ironing machine, the pin 60 will be caused to be moved out ofthe path of the lever 47 Thereafter the switch finger 19 may be operated to not only place the switch in its off condition, but to also return the locking element 35 to itsinitial position.
The switch unit 14 is illustrated as being totally independent of the lock ,element 35. This switch unit serves, in our ironing machine construction, to control the operation of the electrical heating element in the ironinO shoe. i
tow we desire it understood that although we have illustrated and described in detail the preferred formof our invention, the invention is not to be thus limited but only in so far as dened by the scope and spirit of the appended claims. y I We claim v 1. In combination, an electrical switch in cluding a base and al manually operable switch finger, a reciprocable lock element through which lsaid finger extends, said lock element having a channel-like shape and tting over the top and about the sides of said switch, and a means for actuating said element to lock the linger against operation.
2. In combination, an electrical switch including a member for operating the same, a lock element having a channel-like shape tting about and slidably mounted upon the switch, said element having an aperture` cluding a manually operable switch finger, a reciprocable lock element-through which the said finger extends having a channel-like shape, an extension formed integral with one of the sides of the said channel shaped lock element, and a lever for actuating said element to lock the iinger against operation,
connected to the said extension.
4. n combination, an electrical switch includi g a member for operating the same, a mova le lock element through which the said mem er extends, a lever having one end provide with an elongated slot, and fastening mea s extending v'through the said slot in the lever for connecting the lever to the said lock element, said lever serving to control the position of the said element.
5.l ln combination, a top plate, an electrical switch associated with said plate and including a base and a manually operable switch finger extending through an'aperture in the plate, a reciprocable lock-element comprising a channel disposed between the switch and the plate for locking the linger in a given position, said channel shaped lock element being fittedv over said switch base for sliding movement thereon and havin a slot through which the finger extends, an means for operating the lock element.
