6 Claims.

My invention relates to improvements in *a laundry marking machine and has to do, more particularly, withimproved m'eans'for setting the type wheels of such machine, and for retaining them in set positions with-selected type preindicating wheels, that 'isto say, wheels which not only constitute the setting devices but also indicate readily to-the operator the setting-of the type wheels.

Another object-of my invention is to provide a simple and convenient aligning mechanism for retaining the setting andtype wheels in adjusted positions, and'toinsure the alignmentof the selected type at the printing line.

Further objects, and objects relating to details of construction and economies of operation, will definitely appear from the detailed description to follow, In one instance, I have accomplished the objects of my invention .by the devices-and -means set forth inthe following specification.

My invention isclearly defined andpointed out in'the appended claims. A'structure-constituting a preferred-embodiment of-my invention'is illustrated in the accompanying drawings, forming-a part of this specification, in'which Fig. 1 is a vertical, sectional view through .a

laundry marking machine embodying myinvention, parts being shown in side elevation and other parts being partially broken away.

Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig.1; and showingthe "aligning mechanism.

Fig. 3 is a detail, sectional view taken on the line 3-4 (if Fig. 2.

Fig. 4 is a'sectional viewtaken on the'line "4-4 of Fig. 1, and s'howingthe engagement of the aligning bar with the intermediate gears.

In the drawings, the same 'referencenumerals refer to'the same parts throughout-the several views andthe sectional views are taken looking in the direction of the arrows at the ends 'o'f'the section lines.

In general, my invention relates to a laundry marking machine of the type havinga platen, upon which articles to be marked maybe supported, movable to and from printing position and in which, when the platenis' in printing position,

Lit may :be moved toward selected typeto carry the article=thereon againstthetype and take an :impression therefrom. The printing type are mountecl on theperipheries of a plurality of type -wheels,=arrangedparallel to. each other and roitat'ably mounted upon a horizontalshaft. To adjust the type wheels and, thereby, bring. seilected type'tozprinting'position, I provide a'plurality: of setting wheelslikewise rotatably mountiedsparallel to each other on a horizontal shaft, there: being one'setting wheel for each type wheel. These setting wheels are so connected to the type wheels that angularmovement'of a setting-wheel will vcause an equal angular movement of the corresponding type wheel. A simple and convenvil'lllifOIIll, whichthese connections may take, consists of .gears, having the same number of teeth, connected .to the setting wheels and the type wheels-andmeshing with a plurality of in- --.termediate jgears rotatably mounted upon an- :Iither. horizontal shaft parallelto each other and iinsali'gnmentwith the type wheel gears and the setting wheel gears, respectively. The setting wheels :project from the upper portion of the housingof :the machine, in such position that they maybe conveniently manipulated by the .0196131301 :to bring selected type to theprinting position. Thesesetting wheels, preferably, bear onith'eir peripheries indicia corresponding to the .chara'ctersron the printing type, and in the same .angular'relation-to-each other as'are the printing itype. .A sighting bar may be provided extending across the peripheries of the setting wheels,xand having a sighting aperture'therein tthroughiwhich indiciaon the peripheries of said :settingawheelsare visible to the operator. This abar and theindicia will be so located that, when certain'characters are visible through the sighting'aperture,athezprinting.type bearing the corresponding characters will be aligned at printing'sposition. I

iIn-order to lock thersetting wheels and type wheels in adjusted positions, and to make sure th'attthe type-wheels are aligned with the selected printing .:type atnthe printing line, I have provlded'an aligning bar .engageable with'the teeth of theiintermediate gears that transmit motion zfrom thesetting wheels to thetype wheels.- This aligningbar may besupported in arms projecting tirom alframefastened to an aligner shaft. This alignerfzshaft will have an operating handle fixed thereto "outside .of the housing, by which the aligner shaftirnay be conveniently rocked by the 'operatorrtothrow the aligner bar from'engaging to disengagingposition and vice versa. A. spring toggle mechanism is provided which yieldingly holds the aligning bar in either of these two positions.

Referring to the numbered parts of the drawings, the machine has a base 8, from which the frame side members 9 extend upwardly. Secured to said frame side members, or integral therewith, are the housing side members, 40 and H. Each of these has an inwardly extending flange l2 provided with a seat l3, upon which the edges of the housing 14 are seated. As shown in Fig. 1, this housing is cut away at l adjacent the printing position, and the upper portion of the housing is also cut away to permit the setting wheels to project therefrom. The side members, l0 and II, of the housing have their lower edge portions curved inwardly as at l6, adjacent the printing point. The side members, In and l I, are connected by the spacing bars I1 and the parts, I0, H and I4, constitute a housing carried by the frame and enclosing the type wheels, the setting Wheels and the intermediate gearing.

A platen carrier is pivotally mounted on the base 8 and supports a platen 6|, upon which the articles to be marked may be held by the operator while grasping the handles l36, by means of which the platen carrier may be rocked to and from printing position. When the platen carrier is in printing position, the platen 6| will be automatically moved toward the printing type to carry the article held thereon against said type, under control of plungers H11 in the ends of the handles [3%, which are held depressed by the operator while grasping the handles. The platen carrier has a cover 62, with a portion 63 thereof bent upwardly to form a guard. Ears 33 on the platen carrier have sockets formed therein which receive the upwardly projecting posts 96. Included in the connections for supplying pneumatic pressure to operate the platen 6|, is a valve I04 having a control plunger I06, which is depressed, to open valve I04, when the platen carrier is in printing position. The details of construction of this platen carrier, the means for operating the platen, the pneumatic connections thereto and the means for controlling them, are not described or illustrated herein, since they are shown in my pending application, Serial No. 470,052, for Laundry marking machine, filed December 24, 1942, on which U. S. Letters Patent, No, 2,384,035, were granted on September 4, 1945. Certain differences should be pointed out, however, among which is the fact that, in said application, the posts 66 support a combined ink reservoir and ink roller, whereas that is not the case in the machine illustrated herein. The valve I04 is differently located in the machine of the present application, and the plunger N16 is operated by different parts. So far as possible, the reference numerals applied here to parts that :are shown also in said application. Serial No. 470,052, are the same as used for said parts in that application.

A horizontal shaft [8 is mounted in the housing side members If] and II, and extends transversely of the housing. A plurality of type wheels I9 are journaled on said shaft I8, parallel to each other, and each of these wheels has on its periphery a plurality of spaced printing type 20. These type wheels may be lightened by forming the slots 2| therein, a few of which are shown in Fig. l. A gear 22 is fastened to the side of each type wheel I9, coaxial therewith. A horizontal shaft 23 is mounted in the housing side members l0 and H, and extends transversely of the housing. A plurality of gears 24 are journaled on shaft 23, there being one of these gears 2 for each of the type wheels, and each of said gears is in line with and meshes with the gear 22 of the corresponding type wheel. These gears are properly spaced by the sleeves or hubs 25.

A horizontal setting wheel shaft 26 is mounted in the upper portion of the housing, being supported by the housing side member In and II, and a plurality of setting wheels 21 are journalecl on said shaft, parallel to each other, with peripheral portions of said wheels projecting from the upper portion of the housing through an opening formed therein for that purpose. There is one of these setting wheels for each of the type wheels, and each setting wheel bears on its periphery indicia, 23, in the form of characters corresponding to the characters on the printing type Zii, and arranged on the setting wheel in same angular relation to each other as are the corresponding printing type on the type wheel. A gear 29 is fast to each setting wheel El and coaxial therewith, and each of said gears meshes with the corresponding one of the intermediate gears 24. Gears 22 and 29 have the same number of teeth, so that a given angular movement of a setting wheel will produce the same angular movement of the corresponding type wheel. In this way, the type wheels may be adjusted to bring selected type to the printing position by rotational adjustment of the setting wheels, in either direction.

Arms 39, secured to the side members 10 and H of the housing, support a sighting bar 3|, which extends across the peripheries of the setting wheels El, in front thereof, and has a sight aperture 32 therein, through which the indicia on the setting wheels may be viewed by the operator from the front of the machine. This sighting bar is so located, and the indicia are so placed on the setting wheels, that, when certain characters are visible through the sight aperture 32, the setting wheels l9 will be adjusted so that the printing type having the same characters will be aligned at the printing position.

To provide for locking the type wheels and setting wheels in adjusted positions, and for releasing them to permit their adjustment, as well as to align the type wheels with selected printing type in line at the printing point, I have provided an aligning mechanism which comprises a horizontal aligner shaft 34, supported by the housing side members H) and H. One end of this shaft projects through the side member H and has an operating handle 35 secured thereto, by means of which the shaft can be rocked. An aligner frame is provided which includes hub portions 36, mounted on the shaft 34 and secured thereto by set screws 31, and rearwardly projecting arms 38 connected by a crossbar 39. In each of the arms 38, there is formed a threaded socket 463, into which a threaded stud 4| is screwed. These studs can be locked in adjusted positions in the sockets 40 by the lock nuts 42. A block 45 is mounted on each stud 4| between the head 43 thereof, and a collar 44 pinned thereto, and an aligning bar 46 is supported by and extends through these blocks 45. Said aligning bar is of such'length as to extend across the entire set of gears 24, and the blocks 45 are so located with respect to the gears as to fit between certain of them, when-the aligning bar is in engagement with teeth of said gears. Thus, it will be seen that, when the aligning bar is in engaging position, it engages between teeth of all of the in- 5, 5 *iermediate :gears ;24 and :prevents :movement :of type wheels l9 and setting wheels 21. Thesha'ft $4 I can be rocked by the handle 35 to throw-the aligning 1 bar to: the disengaging position, in which the :gears 24, setting wheels 21 and type wheels -t9=are released and freesto rotate.

To provide for yieldingly holding the aligning bar sin .either the engaging I or the disengaging position, I provide an over-center spring toggle mechanism which comprises a pair of bell cranks 41, journaled on hub extensions of the side members l and H, concentric with shaft-3.4. The rearwardly extending arm 48 of each bell crank has a notch 49, whichreceives a stud 50 projecting laterally from arm 36 of the aligner frame, so that said bell cranks are rocked as the frame is rocked to move the aligner 'bar from one position to the other. .The downwardly extending arms '5! of said be11 cranks are forked, and each of the forkarms 52 :has a notch 53, in the lower end thereof. receiving the studs 54 projecting from a pin block 255 slidably mounted on a rod or post 58. "Members .56 are journaled on hub extensions of side members l9 and H concentric with shaft 23, and haveshouldered portions .51 from which the posts iflproject. Springs 9 are mounted on said posts :and compressed between the shouldered portions .51 and the said pin blocks 55. It will be clear that this constitutes a spring toggle mechanismwvhich, in the position shown in Fig. 1,:ho1ds the aligning bar yieldingly in =engagement with the gears, but, when :the shaft 34 ds rocked todisengage the aligning'bar, the toggle mechanism passes over deadcenter so that the springs 59 then act to hold .the aligning bar yieldingly :in the release position.

The operation of this laundry marking machine should be quite apparent from "the description of the parts given above. The articles to be marked are to be held by the operator over the platen 6|, while he grasps the handles 36 and thereby moves the platen carrier to the printing position, in line with selected type which have been brought thereto. The pneumatic mechanism, under control of the plungers I06 and I01, thereupon causes the platen to be projeceted upwardly, carrying the article against the faces of the selected type to take an imprint therefrom. The type, arranged on the peripheries of the type wheels l9, may be brought to printing position by manipulation of the setting wheels 21, which also serve as indicating wheels. Thus, the operator, by manipulating setting wheels 21 Lmtil certain characters show through the sight aperture 32, will adjust the type wheels so that the type bearing the same characters will be brought to the printing line. When this adjustment takes place, the shaft 34 will have been rocked by the handle 35 to disengage the aligning bar 46 from gears 24, and, after the setting has been completed, the handle can be operated to rock the shaft 34 in the other direction until said aligning bar engages with gears 24, which will align the selected type at the printing position, and will also lock both setting wheels and type wheels against movement.

I am aware that the machine described and illustrated herein may be Varied considerably without departing from the spirit of my invention, and, therefore, I claim my invention broadly, as indicated by the appended claims.
