Abstract: 5434. Boult, A. J., [Goldman & Co., E.]. March 10. Feeding sheets.-Relates to a machine for dating, gumming, and affixing labels to bottles &c., and includes mechanism for dating the labels and for picking the bottom label from a pile which is held by adjustable fingers so that labels of any size can be used. The upper part of the machine consists of a rectangular frame 100, Fig. 5, the sides of which are provided with longitudinal ledges 101, on which are adjustably supported supplemental frames 102, 103. Journaled in the frame 103 is a rod 104, from which depend ears forming bearings for a rotary shaft 106 screw-threaded as shown in Fig. 4 and provided with a knurled collar 107. Two similar bars 108, each having two projections, the upper of which is hung on the rod 104 and the lower terminating in a screw nut working on the shaft 106, are provided at their lower ends with inwardly-projecting fingers 111, and these with a finger 113 on an arm 112 rigidly fixed to the frame and a screw adjustable arm 114 form a magazine for a pile of labels 120. Unon the top of the labels rests a plate 122, which is pressed down by a yoke 123 pivotally supported on a bent lever 124 pivotally supported in the slot of a bracket 125, which is recessed to slide vertically on a post 127 of T-shape attached to the frame 103. The frame 102 is provided with mechanism similar to that carried by the frame 103, excepting that the arm 112 is replaced by bars operated similarly to the bars 108. A cross-head 72 connected to a dash-pot 75 is caused to reciprocate vertically by a pitman connexion 73 fixed to a wrist-pin 74 on the disk 68. From opposite sides of a head rigidly attached to the standard 33 rise two similarly bent bars 143, Fig. 4, rigidly fastened at their upper ends to the frame 100. These bars are shaped so as to have a flat inner bearing-face 144, Fig. 26, with a 'slightly offset face 145 outwardly deflected at its lower end 148. In the face 144 are cut recesses 146, 147, in the upper of which is a stud 149. Fastened to the inner face of the lower bent section is a spring finger 150, the free end of which is in a guide groove 151. Fastened to opposite sides of the cross-head 72 are vertical arms 152, Fig. 4, which terminate in yokes 153 forming bearings for the mechanism which, co-operating with the bars 143, picks the labels from the magazines and wipes them around the bottles. Journaled in the yokes are rock-shafts 155 the motion of which is limited. Adjustably confined in collars on these shafts are picker fingers 159, for the labels 139, 120 espectively. The shafts project beyond the bearings and have pinned to them crank arms 161 retained in normal position by springs and carrying antifriction rollers 163 to bear against the surfaces 145. The picker fingers 159, which have been supplied with paste by being dipped into the paste fount 80. move upwards and contact with the bottom label of each pile. The pickers then move down carrying the lowest label of each pile with them. The dating- device is shown in Fig. 23. The plunger rod 62 is reciprocated horizontally by suitable mechanism connected to the drive shaft of the machine. The rod 62 is fixed in a slotted head 196 working in a vertically adjustable frame 189. Within a longitudinal slot 190 cut in the frame works the short arm of a bellcrank lever 197 fulcrumed in the head 196 and carrying a type dating-head 199. The upper side of the frame supports a spring-controlled shaft 192 carrying arms 194 in the outer ends of which is journaled an inking-roller 195. The frame is also provided with an adjustable stop 198 which contacts with the short arm of the bell-crank lever when the h e a d is reciprocated, thereby pressing the type against the bottom label 139.
