My Vpresent invention relates; toan operation chart and indicator'for carrying out a process having ydilferent steps of progression duringthe operation.

The invention while'intended 'for general use is especially well adapted for use in connection ywith laundry washers or so-called Washing wheels, wherein *articles being washed are subjected during the washing operation to different processes. During kal washing operationtheheight of thelwaterk 1n a 'washer must be changed for certain of the different-processes as well as the tempeiature of the Lwater andthe period of time the washer is operated is yalso changed for certain of the processes.- Alarm clocks are now used by operators to indicate the completion of each step or process in a washing operation. p v

When washing different kinds of articles it is necessary to vary'the number of steps or processes for. the respective washing operation which, together ywiththe large1num` ber of such steps or processes, it is very `easy for an operator to become confused as to the particular washing operation being carried out and the stage at which it is in. It is now r necessary for an operator to remember the nature of the articles being washed aswell as whether they are personal clothes such as Y hotel guestV work, hotel flatk work,

. classification used'by the trade.

family wash,"overalls, or kof any other Y, This invention as illustratedv s designed forl use in connection with a laundryl washer and includes angoperating chart on which appears the different stepsfto be performed during a washing operation, the height of waterin the washer, its temperature and the number of minutes the washer is to bev operated during each step of the washing operation. Said invention further provides an'indicator that n may be manually set toindi'cate4 the current step in a washing operation and any step or. steps to ybe eliminated. A u

By the use of my invention an operator by looking at the chart may tell ata glance the different steps to followl in carrying out a iven washing operation and the indicator will'denote the current step in the operation `is closed and ythe visual alarmv given 1931. fseriai No. 547,678.

so that operators may be changed during a washing operation without confusion as to the kind'of articles being washed or as to how farithe operationY has proceeded.

. To theabove end, generally stated, the in vention consists of the novel devices and comf binationsof devices hereinafter described and defined in the claims.

In f the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referringito the drawings: l

Fig. 1 is alfront elevation of the invention f mounted on` a wall;

Fig. 2 is a vertical section taken on the line 2-2 of Figfly *W Fig. 3 is a horizontal section taken on the line 3-3 of Fig. l, on an enlarged scale; and

Fig. il is a fragmentary kdetail view showing he lower end portionofwone ofthe indicator ars.' n l The numeral 5-indicates a panel having on .its'backfapair of brackets 6` detachably secured by screws 7 to a wall 8: An alarm* clock v9 of well known commercial form is mounted on the backof the panel 5 and for the purpose of 'this case, it willonly be neces-V I saryto consider'the alarm portion thereof. This alarm includes a dial l0 and a signal' l1y both` of whichare Aon the yface of the panel 5. Said dial 10 is graduated tcrepresent a pethe graduations is a movable pointer l2 hav-k ing a thumb-piece 13 by `which said pointer ing a vertical column of holders l5, each of which is formed by a series of retaining lugs punched and pressed from the plate 14 for.

card 16 and a plurality of secondary cards 17. As shown, the main card 16 is held by the uppermost holder While the secondary cards 17 are held by the other of said holders. It will be noted that the arrangement of the retaining lugs cf each holder 15 is such that the

cards

16 and 17 may be inserted therein or removed therefrom by an endwise sliding movement at the right thereof.

The mounting plate 14 is detachably secured to the panel 5 by separable fasteners 18 at the four corners of said plate. Each of the fasteners 18 includes a fixed lock stud on the panel 5 and a contracted slot in the The members of the fasteners 18 are so arranged that the mounting plate 14 is applied to the panel 5 by a lateral movement toward the same to pass the lock studs through the slot-s and a down- 'f ward movement of said holder to cause the lock studs to enter the contracted portions of the slots and hold the members of the fasteners 18 interlocked.

The main card 16 has printed thereon the following indicia, reading from the leftto under the headings of Height of water,

iVater temp. an d Min, respectively. The numerals in the first column indicate the height of the water in the washer for the several steps in the Washing operation, the second column of numerals gives the temperature for the water for each of said steps, and the third column of numerals gives the number of minutes the washer is to be operated for each step.

Interchangeably useable operation charts similar to the one illustrated but each having a different washing operation either as to the several steps in the operation, the height of the water in the Washer, the temperature of the Water or the number of ininutes the washer is to be operated for each step. The separable fasteners 18 make it possible to very quickly remove an operation chart from the panel 5 and substitute a different one therefor. In some instances, in place of removing the entire operation chart and substituting a different one therefor, interchangeably useable secondarycards17will be provided for the different steps in the .vashing operation and in which the height of the water. the temperature of the Water and the minutes the washer is to be operated are varied. i

Interch an geably useable indicators are provided for use in connect-ion with the opera-` tion chart and each thereof includes a Hat bar 19, having an its rear edge an outstanding tiange 20, and a slide 21 on said bar. The indicator in use is detachably secured by separable fasteners 22 to the panel 5 in an upright position at the right of the operation chart and closely associated therewith. Said separable fasteners 22 are of the same type as the fasteners 18 and include fixed lock studs on the panel 5 and contracted slots in the two end portions of the bar 19. The slide 21 is applied to the bar 19, as shown in Fig. 3, and frictionally held where set by spring tension. A spring catch Q3 on the panel 5 is arranged to snap into a` hole 24 in the bar 19 above its uppermost fastener 22 and hold said bar against endwise movement from the studs of the separable fasteners Q2. A stop pin 25 on the lower end portion of the bar 19 is arranged to limit the downward movement of the slide Q1 thereon.

Formed on the left hand edge of the bar 19 is a multiplicity of teeth-like pointers 26 longitudinally spaced thereon, one for each step in the washing operation and overlying the adjacent end portions of the secondary cards 17. The backs of the pointers 26 at their junction with the bar 19 are scored at 27 and in case one or more of the steps in a washing operation is to be eliminated the respective tooth or teeth are broken from the bar 19.

Applied to the upper end portion of each bar 19 is a symbol 28 indicating the class of Work for which the particular indicator is to be used, for instance, nets, hotel, guest. and the like. The indicators not in use are hung from the pin Q9 on the panel 5 at the right of the indicator in use.

In starting a washing operation the proper operation chart is hung on the panel and its cooperating indicator is also mounted on said panel. The slide 21 moved to the top of the bar 1.9 for the first operation and the alarm set for the number of minutes the Washer is to be operated. As the steps in the washing operation are completed the operator moves the slide 21 downward on the bar 19 for each successive step and if one of the pointers Q6 is broken away the slide 21 is moved past this step in the washing operation.

Obviously, an operator looking at the chart and indicator may tell at a glance the class of work being done and the current step in the operation.

What I claim is:

1. A chart for a given operation having different steps of progression and including a heading indicatingr the requirement for the operation, indicia indicating the different steps of progression in the operation, and a symbol for each step in the operation and indicating the ratio for the requirement. in combination with a slidable indicator arf for certain of the steps in the operation, and
