LAUNDRY-MARKING I/IAOHINEQ Specification of Letters Patent. Patented Slept, id, lid-fig.

Application filed November 21, 1908. Serial No 463,844. I

To all whom it may concern:

Be it known that I, JOHN C. GEBHAR'I, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Laundry-Marking Machines, of which the following is a specification.

This invention relates to new and useful improvements in laundry marking machines and has reference more particularly to a machine of that type which includes a movable supporting means having type wheels associated therewith, which type wheels are apablc of individualadjustment. l The supporting means is movable with respect to a suitable platen or nail in order to bring the type Wheels into an-operative position.

In the present invention the type wheels are mounted in a casing and the'latter is carried by movable supportingmeans.

The invention aims primarily to provide supporting means of novel construction and employed in combination with novel actuating elements for operating the supporting means actively and for resetting the supporting means after each active operation thereof. 4

The invention includes as a further novel feature, the specific manner of mounting the type wheel casing with relation to the supporting means whereby said casing has an initial movement independent of said supporting means to bring the determinate line the anvil, and whereby after of type over a fursuch initial movement of the casing,

ther movement thereof with the supporting means is had in order to effect the marking operation.

The invention possesses further novelty in the provision of automatic means for locking the type wheels against movement after they have been set and in the operative position of the casing. This locking, means is sup-v plemental to a means for locking each individual type wheel against movement after an adjustment thereof.

The invention comprehends the above novel structural features toward the ends of simplicity in construction, reliability and accuracy i'- operation and inexpensiveness in the reduction of the number of parts ordinarily employed in marking machines of the general type stated. v

The invention will be best understoodin view of the following description which is to be read in connection with the i iccoznpanying drawings wherein is shown a preferred and advantageous form of construction in accordance with the present invention, while the novel features of theimprovement are defined in language of proper determinative character in the claims appended at the end of this specification.

In the said drawings :-Figur e l is a perspective view of a marking machine constructed'in accordance with the present in vention and showing the complete assemblage of parts, the elements being in their normal positions. Fig. 2 is a central longitudinal section illustrating the structural details of the movable type casing, the movable supporting means and the actuating parts, the elements being in the position shown in Fig. 1. Fig. 8 is a side elevation with parts broken away and parts in section, the machine being shown as in operation. Fig. i is a transverse sectional view showing the arrangement of the elements assembled upon the main supporting shaft. Fig. 5 is an elevation in detached relation of one of the type wheels and its adjusting means. Fig. 6 is a detail perspective view of one of the arms of the supporting means, the other arm be ing similar in construction. Fig. 7 is a detail perspective view of a bell crank lever forming an element of the operating train which will be described in detail, and Fig. 8 is a similar view of an abutment member which is mounted 'on the main supporting shaft and which is associated with the resetting means previously mentioned.

Similar characters of reference refer to corresponding parts throughout the several views.

For convenience the operating parts are carried on .a base 1. which is mounted on a supporting pedestal 2, the latter being preferably hollow and having at its base a. projecting flange 3 for attachment to the floor. The base 1 is preferably detachably assembled upon the, pedestal 2 as by bolt and nut connections 8 shown in Fig. 2: At the frontend of said base an anvil 41 is provided, in which is set a raised section 5, preferably of rubber, which serves the'purposes of a platen and shall hereafter be referred. to by that name. The base 1 is formed at its rear end with a pair of spaced upwardly projecting bearing members 6 in which jonrnaled a. transverse shaft 7. which forms the main supporting shaft 6. A shaft extends transversely of the pivlotall lever 20 as s abutment member 26 illustrated more par-' ticularly in Fig. 8. The member 26 depends The type wheel casing is indicated by the numeral 8 and is preferably supported pivotally with relation to arms 9 oneof which is illustrated more particularly in Fig.

casing 8 and in addition to serving as the pivot for operating lever quadrants to be later described, serves as the connection between the casing 8 and the arms 9. Accord ingly the ends of the shafts 10 are extended and journaled in bearings 11 formed in the upper ends of the arms 9. The latter are of angular formation and include horizontal portions 12 and vertical pertions 13 which extend upwardly from the "portions 12 at a substantial right angle thereto. The arms 9 have at their rear ends ofi-set collars 14: which surround the shaft 7, and are held fast thereon by an .suitable means. The type w eel shaft is indicated by the numeral 15 and is disposed transversely of the casing 8, beyond which its ends are ex: tended for a purpose to be'hereinafter set forth.

The casing 8 and the arms 9 are moved by atrain of elements includi essentia ly a bell crank lever 16 which is loosely mounted upon the shaft 7, and an angular link 17 connecting the upper end of the lever 16 with the casing 8 at the lower rear portion, as at 18. The link 17 is connected to the longer outwardly projectin arm of the lever 16, and an elongated ll 19 is connected to the shorter inwardly projecting arm of said lever, the link 19 extending through the edestal 2 and being ivoted to anoperatin lever 20 mounted at t e base of the ed estafi and provided with a treadle'l 21. e. lever 20 projects through a slot 22formed in said pedestal and is preferably upheld so that the lever 16 and thecasing 8 are sustained in a normal position by means of a s ring 23 of retractile spiral form, one end 0 the s ring 23 being connected to the hown and the other end of said spring being connected within the pedestal 2. The spring 23 affords a means for resetting thelever 16 and the casing 8 with relation to the arms 9 and means are further provided for resetting said arms 9, this last mentioned means comprising preferably a member 24 which is secured to the base 1 at the rear end thereof and which is formed with spaced lugs 25 cotiperating with an from the shaft 7 and is formed with collars 27 which surround said shaft andare 'held fast thereon.

' The member 26 is constructed with openings 28 through which are passed pins 29, the latter extending also through openin s in the lugs 25 and having at theirouter en s pins 29 have a certain degree of play, the openings 28 and the openin s in the lugs 25 being of greater diameter t an said pins to allow of the necessary play. The pins 29 have their inner ends, threaded to receive nuts 31 which confine expansive coil springs 32, the latter surrounding the pins 29 and bearing against the nuts arid.against the lu s 2 he arms 9 are formed with projecting bearings 33 ,which support the shaft of aninking roller 34, the latter'contacting with the peripheries of the type wheels within'the, casing 8; hence it will be seen that when the casing 8 is moved on its pivot 10, the roller w1ll automatically supply ink to the surfaces of tlyie type wheels, the latter traversing said r ler aswill be readily understood.

I The type wheels are indicated by the numeral 35 and are formed with the necessary and desirethcharacters, alphabeticaland numerical, the said type wheels being mounted for rotation on the shaft 15 preuiously referred to, as best re resented in Fig. 2. A pinion 36 is made ast to the hub of each ,type wheel, bein :cast'integral therewith or secured in any ot er suitable or desiredmanner. The type wheels are each set whereby thedesired character is positioned with respect to the platen 5, the setting means comprising quadrants 37 which are in mesh with a correspondinfi pinion 36 and which. are mounted pivota y on the shaft 10 previously referred to. The quadrants 37 are formed with .lever arms 38 which project through slots 39 provided in a cover plate 40 for the /casing 8, the projecting portions of the arms 38 serving as handles. The plate 40 is graduated and marked with suitable char acters adjacent each slot, whereb the operator ma be able to convenient y set" the type whee s to the desired position, it being understood that by bringing a lever 38 to 5 position adjacent the character desired, the corresponding wheel 35 will be set through the means described to a position whereby such character will be presented to the piece to be marked.

Meansare provided for locking the levers 38 and consequently the type wheels controlled thereby against accidental movement and such means preferably comprises pawls 41 which rest upon or are secured to springs 42, the latter hein secured to the levers 38 and acting to l10l( the pawls 41 in engage- J ment with teeth 43 formed on the inner or 'under face. of 'the plate 40, the teeth 43 being arranged adjacent each slot 39-and corresponding in number to the type on the corresponding type wheel 35 and to the markings on the plate 40. It is also referable to provide means for positively ocking the wheels 35 against movement in the operative position of the casing 8, and accordingly the link 17 is formed with a prothe pawls 41 such engagement tween the finger 'ing and prior to tion of the portions 12 and 13.

iecting finger 44 which extends transve 'sely of the type wheels 35 and engages between the peripheral type bearing projections thereof in the operativeposition of the casing 8, as-shown more particularly in Fig. 3, the finger 44 locking the' wheels against movement and also serving as an alining means.

In order that ready access may be hadto the type wheels for the purposes of cleaning the same, the front wall of the casing 8 is provided with a movable section 45 which is hinged to the upper stationary section as at 46 and is held in closed position by a suitable latch means 4-7.

In order that the difference in purpose bell and the locking pawls d1 may be made clear, it should be stated that simply hold the levers 38 against accidental displacement, but do not engage with the teeth 43 with sufficient force to hold said levers against i'nanual movement. They do, however, prevent too free a degreeof manual movement and by clicking as they engage between the teeth give an audible indication of the movement of the type wheels the distance of a single tooth. The finger 44, however, alines the type and positively holds the wheels 35 against movement, at the same time preventing manual movement of the levers 38. Said finger engages with the type wheels at the completion of the initial relative movement of the casits subsequent downward movement toward the platen. remaining in during the subsequent downward movement of the casing and all the while maintaining the type in proper alinement. Thus if the levers 38 were accidentally struck as by the arm of the operator during the marking operation, such striking would ordinarily effect movement of the wheels 35 from the positions into which they had been set. but owing to the provision of 14, the lovers 38 will have no movement if accidentally and violently struck, and consequently the wheels 35 will not be moved. In this manner the reliable operation of the machine is assured.

In use the operator sets the wheels 35 to make the desired impression upon the material, and then depresses the lever-.20. Such action moves the bell crank lever 16 inwardly and effects an initial movement of the casing 8 with respect to the arms 9, such initial movement being continued until the projecting endsof the shaft 15 engage the arms 9, as shown in Fig. 3, as at a point it the juncthe projecting ends of the shaft 15 serve as positive connectors whereby the movement of the casing 8 being continued by means of the lever 20, the arms 9 will be moved with respect to the shaft 7 as a. pivotal axis'by virtue of the engagement of Thereafter the ends of the shaft 15 with said arms, as above set forth. When the arms 9 are thus moved, the shaft .7 is turned therewith and the member 26 being fast on the shaft 27 is moved outwardly, thus storing power in the springs 32, as will be readily apparent. This movement of the arms 9 brings the face of the type wheels upon the material to be marked, the latter being of course positioned on the platen 5. When the lever 20 is released the spring 23 resets the casing 8 to its normal position with respect to the arms 9, through the medium of connections 19, 16 and 17. At the same time the springs, 32 bearing against the nuts 31. reset the arms 9 to the normal position shown in Fig. 2- and the machine is ready for another operation. The wheels 35 are set when the casing 8 is in its normal inoperative position, as shown in Fig. 2, and in such position of said casing the type wheels do not contact with the inking roller 34. Such contact is only had dur ing the movement of the casing and by the single row of type which is used for marking,

'such row touching the roller 34 as the casing 8 in its initial movement passes over said roller. The initial movement of the casing 8 also serves to center the previously inked row of type above the work, and the downward movement of said casing in continuation of its initial movementefi'ectually carries out the marking operation.

The improvement has been referred to as a laundry marking machine for. the reason that machines of this type are employed for the most part in laundry work, but it is of course apparent that the invention covers all the usages to which the machine may be put. Ialso desire it to be understood that while the form of the invention herein shown is advantageously employed, it serves merely as an example of illustration of the basic princi les of structure and operation involve and that other forms of the inveninvention, I
