Abstract: 2161. Fischer, C. R., and Stoll, J. E. Jan. 27. Branding by heat.-A machine for branding bottle - sealing caps is constructed with means for separating dust from the caps and feeding them, in pairs, to a conveyer in such a manner that the cork faces to be branded a r e directed towards the dies. The dies are carried by spring-controlled arms operated by cams to cause a pair of caps to be branded at once, the caps being carried to the dies by the intermittently rotated conveyer which is provided with pockets moved successively into position to receive the caps and to carry them between the dies. The caps 44, which are of the kind formed of metal with a cork lining, are placed in a hopper 67, Fig. 2, and pass from this through an opening 66 into a chamber 64 in which rotating blades 72 agitate the caps, causing dust and like particles adhering thereto to be separated from the caps and to pass through reticulations 68 in the chamber 64 into a drawer 69. The blades 72 direct some of the caps into a rotating chamber 57 driven by a cord 59 and pulley 58 from a countershaft 22, Fig. 1. The chamber 57 is formed of two substantially conical-shaped members separated by an apertured disk 77 secured to the two members by screws 78. The caps pass into both parts of chamber 57 and are thrown out by centrifugal force into the outermost parts of the chamber adjacent to the edges of the partition 77, which is formed with studs 79 which prevent all but the caps that are properly arranged with their cork faces outwards from passing between them. These caps pass into a divided open portion 76 of a fixed annular member 74 which surrounds the chamber 57, the right - hand portion of this member 74 being closed but provided with a pivoted member 81 which can be raised to permit of access to the chamber 57. The caps pass in pairs from the passage 76 to a vertical shoot 41 divided by a partition 42, and from the shoot 41 the caps pass into an intermittently rotated disk conveyer 35 rotating on an horizontal axis in a housing 10 formed with apertures for receiving and discharging the caps, and with side apertures to receive the branding-dies 11 which are carried by levers 13, 14 pivoted to a stud 15 and acted on by cams 25, 26 on a shaft 18 driven by bevelgearing from the shaft 22. The conveyer 35 is rotated intermittently by the engagement of a spiral cam-surface 37 carried by the shaft 18 with a notch 36 formed in the disk, and during the periods of rest of the disk it is held by a locking-surface 39 secured to the shaft 18 below a flange 29 which supports the levers 13, 14. While the disk 35 is locked the arms 13, 14 are moved inwards under spring action, and the dies are forced on to the cork parts of the caps, and so effect the branding. The dies are dovetailed in their holders, and are heated by burners 46. The caps are held in place in the shoot 41 and released at the proper times by means of bent arms 52 fitted with adjustable screws 53 which grip the centres of the lowermost caps. The arms 52 are carried by pivoted arms 49 acted on by a spring 54 and depending into the path of the levers 13, 14 so as to cause the screws 53 to grip the caps during the movements of the conveyer 35, and release them when the conveyer is at rest so that the lowermost caps pass into the pockets of the conveyer then under the shoot 41.
