Abstract: 190,526. Crosland, G. A., Jenner, A. L., and Jenner, C. E., (trading as Jenner, A. & C.). Sept. 19, 1921. Index type-wheel machines for marking laundry articles; hammer - impression arrangements; matrix-supports. - A movable work-support for inserting the articles in the machine is adapted to operate an impression-hammer, an adjustable operating-spring for the hammer being strained and tripped by means of the work-support; the work-support may operate also a work-shield and inking-pad mechanism. Discs c, revoluble on a shaft d and provided at the bottom with types, are set by means of finger-pieces e, the setting being shown at a slot i by means of other types. A work-support k rocking on trunnions 2 is formed with a curved table 4 for the work, and supports an impression-member q passing through a slot 6 in the table. The table may be furnished with rubber studs 5. An impression-hammer 16 for striking the member q is secured to a shaft 11 provided with an arm 10 connected to an adjustable spring 15 and provided with a pin 12 for engaging a notch in a link 8 which is connected to the work-support. On rocking the work-support, by means of knobs 7, the spring is stretched and when the member q is in register with the set line of types, an eccentric abutment 14 trips the link and thereby permits the spring to operate the hammer. Aligning for impression. - Aligning-notches g in the type-discs c co-operate with dogs f. Pad inking-arrangements.- On rocking the work-support k, an inking-pad w, Fig. 5, is moved into and out of contact with the types and is then pushed underneath a cover 26, the latter movement carrying the pad out of the path of the impression-member q. The pad w and an ink-well 37 are detachably mounted on a channelled base 25 formed with curved slots 20 and straight slots 28 engaging rods 19, 27 on the work-support and a bracket a respectively. A stop-lever 24 pivoted on the base normally engages the rod 27. On rocking the work-support, the rod 19 rides over a V-spring 21 on the base, and the base is lifted and dropped to move the pad into and out of contact with the types. The rod 19 then engages and releases the stop-lever 24. and the base is pushed into the channelled cover 26. At the end of the movement, lugs 33 on the base engage the ends of slots 34 in the cover, and lugs 31 on the base engage lugs 32 on the cover. The cover is closed tightly by the engagement of the rod 27 with inclined slots 29 in the cover. The ink-well 37 is mounted between lugs 35 on the base 25 and is retained by a spring catch 36, the top 41 of the ink-well having a lip 39 for retaining the pad w, and a depression 40 for catching superfluous ink. The top is provided with a sliding lid 42. Matrix-shields. - To prevent the types fron. soiling the work, a shield f, having a slot p for the passage of the impression-member q, is interposed between the work and the types when the work-support k is rocked. The shield is pivoted on the shaft d and is provided with a pin o engaging a cam-slot n in a plate m on the worksupport. To assist in holding the work out of contact with the types, the shield may carry, on a spindle s, fingers t pressed outwards by springs u.
