STAMPING MACHINE Filed Dec. 29, 1954 r en INVENTOR 504 [/F5/ 72 BY k ATTORNEY Patented June 25, 1935 STAMPING MACHINE Sol Lifsitz, Detroit, Mich, assignor of one-half 'to Israel M. Hertz, Detroit, Mich.

Application December 29, 1934, Serial No. 759,633 11 Claims. 01. 101- 37) The present invention pertains to the marking of pieces of laundry, particularly such pieces as are rented by a laundry supply service and pieces owned by hotels and other institutions. At the present time, the marking or stamping of the pieces is done by hand, probably because a mechanical devicepresents several difficulties. First, a piece of laundry must be re-stamped one or more times before it is discarded, and not all the pieces in a wash require stamping. Again, a timed mechanical marker would require a complicated adjusting mechanism, inasmuch as the pieces handled in different batches, or even in the same batch, at times are not of uniform 5 length. w

The principal object of the present invention is to provide a stamping device which is mechanically driven but manually controlled, in order to provide for the irregularities previously mentioned. A second but very important object is to make possible the stamping of the laundry without the expenditure of an appreciable amount of extra time, by causing this operation to be performed during the handling of the work in some other laundering process.

It is well known that the ink adheres to the cloth more firmly if the stamped area is given a heat treatment immediately after the ink is applied. In this connection, still another object of the invention is to furnish this heat treatment.

In order to accomplish these objects, the invention embodies a stamping roller journalled in a suitable bracket carried bythe frame work of a conventional laundry machinein which the work 35 is ordinarily subjected to heat, such as a mangle. The roller is mounted close to the conveyor which feeds the machine and is so positioned that parts of its periphery are adapted for tractive engagement with the work carried by the conveyor. Intervening parts of the roller are notched or recessed, and when any one of these parts is disposed immediately over the box, the roller does not turn. The roller assembly carries push pieces within convenient reach of the operator while the latter is feeding a piece of work to the machine. If the piece is to be stamped, the operator pushes the push piece to'bring a tractive part of the roller into engagement with the work, whereupon the roller turns and brings the stamp proper into engagement with the work. When the next recessed part of the roller comes to a-position immediately over the work, the tractive engagement is broken and the roller stops turning. Thus, the work is stamped only when the operator actuates one of the push pieces.

The invention is fully disclosed by way of ex-' ample in the following description and in the ac-' companying drawing in which.

Figure l is a side elevation of the device;

Reference to these views will now be made by.

use of like characters which are employed to.

designate corresponding parts throughout.

In Figure l, the numeral indicates a part of the frame of a conventional laundering machine, preferably one that heats the work passing therethrough, such as a mangle. The support'for'the stamping device includes two clamp pieces 2 en gaging the member 4 and held together'by bolts 3. A spring arm l is held by the. bolts, and one or more shims 5 may be inserted between the arm l and the nearer member 2 if necessary or desired. A bearing member 6 has a shank 1 formed with tapped holes 8. These holes are adapted to lie beneath slots 51 in the free end of the member 4; whereby the bearing member 6 may be secured adjustably to the member 4 by means of thumb screws l9 passed through the slots 9 and screwed into the holes 8.

In the arms of the member 16 is journaled a shaft H to which is secured a roller [2. Beneath the roller is a flat conveyor l3 which feeds. the machine, and this conveyor rides over a table It at the roller. It will be seen, however, in Figure 3 that the roller itself does not engage the work l5 passing through the machine. In the periphery of the roller are inserted one or more stamping members it arranged parallel to the axis of the roller and spaced from each other. The face ll of each stamping member is at such a distance from the axis of the roller that it can come into tractive engagement with the piece 40 i5, and each face is further formed to impress the work with characters represented by the letters A, B, C, D,,E, F, G in Figure 2; It is evident that when oneof the spaces is between members I6 is disposed immediately over the work, the roller 45 does not turn. The means for bringing a stamping member into engagement with the work,

when and as desired, will now be described.

This means consists merely 'of one or more push pieces, corresponding to the number of members I 6 carried by the roller l2, associated with the roller assembly and within convenient reach of the operator while'the latter is feeding a piece of work to the machine, so that the roller assembly may be turned to bring one of its tractive Figure 2 is a fragmentary plane view thereof,

7 parts into engagement with the work. While the push pieces may be carried directly by the roller itself, a preferred construction is illustrated herein. A disk 20 is carried by the shaft II at each end of the roller and is the same ,cir-

cumference as the faces I! of the stamping member" IS, in order also to have tractive engagement with the work as may be seen in Figures 1 and 2.

However, the periphery of each disk is notched at 2| opposite the ends of the spaces I8 between the members IS. The notches 2i are narrower than a the spaces l8 and the latter'are overlapped by the unmutilated parts 22 of the disk 2!! at the trailing side of each space l8, with reference to the direction of rotation indicated by the arrows in I Figures 1 and 3, for a purpose which will presently appear. An inking roller- 23 is journaled in the a bracket 6', and is engaged by the faces H as the roller turns on its axis.

Finger push pieces 24 are fixed to or formed integral with the disks 20 and project outward from the outer faces thereof. These members lie wholly within the projected cylindrical surface embodying the stamping faces I! or the periphery of the disks 20'. The reason for so positioning the push pieces is to maintain them entirelyiclear of themo'ving work piece l5 and out of driving engagement therewith or with any other moving part of the machine. They correspond in number to the stamping member l6 carried by the roller l2;

When a space 18 and its aligned notches 2| lie immediately'over the conveyor, just before reaching the position shown in Figure 3, the stamping device is idle and can. be brought into tractive engagement with the'work only by pushing one ofthemembers 24. These members are so positioned that the lowermost one can conveniently be pushed by the thumb of the operator as he lays a piece of work on the conveyor 13 to be fed to the machine. 3 A slight push brings the leading edge of an unmutilated segment of a disk 20 into engagement with the work, whereupon rotation of the roller is initiated. Because of the previously described relations of the overlapping parts 22 to the spaces I8, the stamp is applied to the work at a pre-determined distance from the entering edge of the work. This distance depends on the spacing between notches 2| which may be established as desired. As the work passes through the laundry machine, it receives a heat treatment which sets the ink of the stamp.

The operator need use only one hand to start the roller, and only one disk 20 is essential, but.

the provision" of two disks adapts the device for right handed and left handed operators or permits the operator to change hands from time to time.

The'shaft H is in the form of a bolt having a nut23 at one end so that a roller of a different size or with different stamps may be inserted when desired. Similarly, the inking pad is held bya bolt 26 and nut 21 for interchangeability. The resiliency-of the member 4 permits a stamping machine, a shaft, aroller cylindrical surface projected from the facial cir-' 'cumference of said stamping member.
