FRANK M. OVERHOLT AND FRANK M. STEINER, OF MINNEAPOLIS, MINNESOTA.
Lanimnv-nxrmoron.
and FRANK M. S'rnmnn, citizens of the United State's, residents of Minneapolis,
county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Laundry- Extractors, of which the following is a s ecification.
In the operation of a -aundry, --1t 1s ens-- tomary to place the clothesin afcentrifugal extractor where they are ra idly revolved and=the water thrown off y centrifugal force until' the garments or otherarticles-g laundried arein suitablecondition "g fort emangle.
It sometimes happens that an-operator bein will allow the separator. to run for too long a time so that too much" water is taken out of the clothes and there is danger of burning them when they pass through the rolls of the mangle. Furthermore, this unneces sary operation ofthe separator uses up the power and increases the overhead expense.
. The object, therefore, of our invention 1s to provide an attachment for the separator by means of which the power will be cut oil, and the machine stopped when the clothes are sufiiciently dry for delivery ,to the mangle. 1 The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.
In the accompanying drawings forming part of this specification, Figure 1 is a detail sectional view illustrating the application of our invention to a laundry machine, Fig. 2 is a plan view of the belt shifting mechanism, Fi 3 is a detail sectional view, showing the evice for oplerating the control mechanism mechanica y when it is desired to stop the machine, Figs. 4, 5 and 6 are detail vlews, showing the diiferent positions of the locking mechanism, Fig. 7 is a detail view of a modified construction, Fig. 8 is a detail sectional .view of the locking mechanism of the modified construction shown in Fig. 7 Fig. 9 is a detail sectional view showing still another modified construction.
- In the drawing, 2 represents a laundry extractor, in which the wet clothes are placed for extracting the water therefrom. This extractor is of ordinary construction and Specification of Letters Patent. Application filed March a, 1915. serial No. 12,825.
.24 to the receptacle 23. A waste pipe 25 Patented Sept. 14, 1915.
is driven by a belt 3 from a pulley 4 mounted on a shaft 5 on which is secured a driving pulley 6 and a belt/7. A loose pulle 8 is mounted on the shaft and a belt shi ter bar 9 has the usual fingers 10 on aging the sides of the. belt to shift it from t e loose to the driving! pulley, or vice versa, as may be requiredf in the operation of the machine.
The beltshifter bar 9 has a suitable handle 11 and is mounted to slide in ides 12 and'13 and is provided with a spring 14 that'is' put under tension when the belt is shifted from the loose to the driving pulley for returning the belt to the loose pulley when the shifter bar is released. The bar has notches 15 and 16 in its upper and lower edges, arranged in staggered relation, as shown in Figs. 5 and 6 and mounted on the guide 13 is a slide 17 having slots 18 therein to receive bolts 19 which secure the slide on the guide 13 and allow it to be moved vertically thereon. An opening 20 is provided in the slide in which the bar 9 is movable longitudinally and the upper and lower edges of this opening are adapted to enter the' notches 15 and 16 in said bar and lock it against premature movement in either direction. The slide is so arranged with respect to these notches that when it is drawn down to the limit of its downward movement it will be in position to engage the notch 15 andlock the bar while movement in the opposite direction, will disengage it from the notch 15 andengage it with the notch 16, assuming, of course, that the belt shifter bar 9 is in proper position to engage with the slide. The lower end of the slide is connected by a rod 21 with a float 22 that is vertically movable in a receptacle 23 arranged near the base of the separator. This receptacle has an open top and has a pipe connection 24 above the float with the lower walls, of the separator so that the water thrown out by centrifugal force from the clothes will be conducted through the pipe leads from the receptacle above the float.
Within the receptacle 23 and above the float is a partition or wall 26 having'perforations therein through which the water delivered by the pipe 24 may flow down into the receptacle and 'under the float, and the eifect will be to raise the float andthe rod 21 connected therewith and move the slide, 17.
This will take place soon after the machine is started. To start the machine, the operator will grasp the handle 11 and draw on the belt shifter bar until the belt is shifted from the loose to the driving pulley and this .movement from the position of the bar shown in Fig. 4 will put the spring 14 undercompression and bring the notch 15 to a point where the slide 17 will enter the notch, being drawn down by the weight of the rod 21 and the float 22. The shifter bar will thereby be locked and the operator may: release the handle. The machine being started,-1will throw water out of the clothes, which, accumulating in the bottom of the.
extractor, will flow down through the pipe 24'int'o the rece tacle23 and gradually raise tliofloat22 to isengage the slide from the :tnot ch 15.; It will engage the notch 16 in the underside of the shifterbar and lock the bar again'st endwise movement and pre vent theshifting of the beltfrom the driving pulley to the loose pulley.
f'chine continues, the volume of water separated fromthe clothes and delivered through the pipe 24 will decrease and when the discharge through the waste cock 27 is greater ifthan; the supply delivered through the pipe 24,, the float will sink by gravity and release the. shifter. bar, and as soon as the shifter bar. is released, the spring 14 will throw it to its normal position and move the belt from the driving to the loose pulley. By: making the operation of the machine depend upon the volume of water thrown out -from the clothes rather than timing its operation for any specified number of min utes, we are able to stop the machine when any desired stage of dryness of the clothes has been attained, forwhenever the column of water delivered to the float receptacle falls below a predetermined volume, the. float will descend and release the beltshifter bar to shift the belt to the loose pulley and stop the machine, In this way the operator is able to extract any desired amount of water from the clothes and not only keep the clothes. sufliciently moist, but also sufliciently dry for the mangle, and also efl'ects a considerable saving in the power for operating the machine, as well as the wear and tear on the mechanism itself.
It is desirable in.a device of this kind to provide means for a manual release of the shifterbar. We therefore provide a substantially V-shaped recess 29 in the slide.17,
adapted to receive a lug 30 carried by a lever be released, allowing the spring 58 to throw 13 31, said lug engaging the edges of the recess and operating the slide to release the shifter bar when it is desired to stop the machine for any purpose.
In Fig. 7 we have shown a modified construction," which consists in providing a bracket 32 having an arm 33 on which a lever 34 is pivoted. One arm of this lever has an opening 35 to receive the shifter bar, the upper and lower edges of the opening engaging the notches in the bar as previously described with reference to the construction in Fig. 1. The opposite arm of the lever 34 has a link 36 pivotally connecting it with a beam 37 pivoted at 38. Onearm of this beam has a weight 39 thereon and the other arm is provided with a pan 40 in position to receive the water from a waste pipe 41 communicating with the separator, the bottom of the pan having a valve 42 for regulating the escape therefrom. .When this pan is filled with water from the pipe 41, the beam 37 will be tilted to raise the lever 34 and disengage it from a notch 43 in the lower edge of the shifter bar 44 and allow the upper edge of the opening 35 to engage the notchr45 in the upper edge of the bar, thereby locking it in position to hold the belt on the driving pulley. As the flow of water into the pan 40 diminishes, the weight and pull the lever 34 downwardly to disengage it from the notch 45 and allow the shifter bar to change the belt.
In Fig. 9 a similar controlling mechanism is provided for regulating the switch of a motor through which: the extractor is operated. In this modification the slide 46 is movable vertically, as described with reference to Fig. 1, normally held in its raised position by a spring 47 and carries a bucket 48 at its lower end having a waste cock 49 and arranged in position to receive the water thrown out from the clothes from a pipe 50. The motor switch has a lever 51 pivoted at 52 and engaging the contacts 53 at one end on the other side of its pivot. The lever is pivotally connected with a bar 54 that is movable ina slot 55 in the slide 46 and has oppositely arranged notches 56 and 57 to receive respectively the upper and lower edges of the slot 55. A spring 58 is provided in the switch and normally tends to throw the switch lever out of engagement with the contact 53. As the bucket 48 fills with water, the slide 46 will move downward out of engagement with the notch 56 and into engagement with the notch 57, which, as shown inthe figure, is made a little longer than the slot 56. When the flow 12 of water into the bucket decreases to such a point that the tension of the spring 47 overcomes the weight of the bucket, it will be raised with theslide and the bar 54 will 39 will tilt the beam in the other direction nearer the lever 51 out of engagement with the contacts 53, thereby breaking the circuit and stiwpin the motor.
