Title: Improvements in or relating to machines for mounting safety razor blades on a strip or the like
IPC: B65B25/00
Filed: 1934-07-10
Abstract: 418,813. Wrapping-machines. BASSAT, H., Ohligs, Solingen, Germany. July 10, 1934, No. 20201. [Class 94 (i).] Safety razor blades 2, Fig. 1, are mounted on a strip 1 having recesses 4 and tongues 5 adapted to pass through the end holes 6, being turned down flat to secure the blades. Perforations 7 facilitate separation into individual packets. The strip 1, and a backing strip 3 which may bear advertisements, are drawn beneath a vertically movable die 10, Fig. 3, which cooperates with a fixed die 9 and is actuated by an eccentric 15 to form the recesses 4 and the tongues 5, a cutter 24 forming the perforations 7 at the same time. The strip is fed by a gripper 29 pivoted at 28 to a slide 25. The slide is reciprocated by a connecting rod 33, pivoted at 32 to the gripper, and to a pin 34 adjustably mounted on a wheel 35. The action is such that the gripper is first rotated in a clockwise direction to clamp the strip against the slide, which is then moved to the right, Fig. 3, further rotation of the wheel 35 disengages the gripper and returns the slide. The strip passes to a drum 43, Fig. 15, upon which it is pressed by spring strips 45<a> to cause teeth 44 to push the tongues 5 upwards and to enter the incisions corresponding thereto. A blade 2 is now positioned by fingers so that the tongues 5 pass into the end holes 6 and the strip passes beneath a folding plate 85 having oblique edges 86 which turn down the tongues and cause them to overlie the surface of the blade and secure it to the strip. The blades are fed by the apparatus shown in Figs. 11 and 14. They are held on prongs 55 on a plate 54 sliding in a support 56, and, after arrival above a feeding plate 57 are pressed downwards by a weight 60 so that the lowermost enters into a recess 63 of just sufficient size to receive one blade in a position below the ends of the prongs 55. The feeding plate moves into juxta-position with fingers 45, Fig. 11, covered with rubber 71, so that the fingers are disposed above and below the blade respectively, the lower blade having entered a recess 70 in the feeding plate. The fingers are actuated to close upon the blade, and, after the withdrawal of the feeding plate 57, move downwards with it to the position shown in Fig. 15. The strip may be severed at intervals along the line of the perforation.

[Also in Group XIII]  Relates to rotary regenerative heat-exchangers comprising one or more rotors incorporating a heat transfer material which as the rotor rotates, first absorbs heat from a gas to be cooled and then gives up this heat to a gas to be heated. According to the invention, the or each rotor is caused to rotate by providing it with suitably shaped vanes or blades on which the heatexchanging fluids impinge. The heat transfer material may comprise a solid or liquid or fluent material. In Fig. 1, solid heat transfer material is itself shaped to form the blades 2 of the rotor 1. These blades may be metallic or otherwise depending upon the prevailing operating conditions. A stationary. housing surrounding the rotor is provided with fixed blades 3. Fig. 2 shows solid heat transfer material 1a (e.g. wire gauze) arranged in compartments formed between radially extending walls shaped at their edges 2a, 2b to form the rotor driving blades. Figs. 5 and 6 show an arrangement utilizing a liquid or fluent heat transfer material. Two units are provided (only one being shown) each comprising a rotor 52 rotating in a housing 51, a single heat exchanging gas being passed through each unit and the liquid or fluent heat transfer material being circulated through each unit in turn, absorbing heat from one gas passing through one unit and giving up this heat to a gas passing through the other unit. Blades 55a are provided on the rotor and are shaped to rotate the rotor when impinged on by the gas flowing therethrough. Smaller blades 55b may be provided between the vanes 55a to distribute the gas evenly around the rotor. Fixed blades 53, 57 are provided at the gas entrance and outlet of the rotor housing 51. The fluid heat transfer material enters the rotor through a pipe 64, thence flows radially outwardly through tubes 61 and is distributed by nozzles 63 in the form of fine droplets into the gas stream. After passing across the gas stream and absorbing or giving up heat to the gas as the case may be, the heat transfer fluid leaves the rotor through outlet 66 and thence through outlet 67 of the housing for circulation to the other of the two units from which it returns to the first unit. The heat transfer material may be subjected to cooling, heating or cleaning means in passing between the two units and the quantity and velocity of material passing through each unit may be regulated.

Filed: 1925-08-25
Abstract: 258,410. Warbrook, F. G. Aug. 25, 1925. Condensers of the type wherein the capacity is varied by variation of the distance separating the plates, are mounted between a pair of supports in such a manner as to be capable of rocking movement about both points of support and have means for varying, the relative positions of the supports for modifying the condenser law. In the form shown in Fig. 1, the condenser a which is assumed to include a spring forcing the end plates a<1> and other plates apart, is mounted between supports b, b<1> engaging conical recesses in the end plates. The support b<1> is a screw for varying the maximum capacity whereas the support b is a pivoted lever c movable about its pivot by means of a screw e against the action of a spring d to vary the capacity by increasing the distance between the end plates. Starting from the minimum (dotted) position, equal movements of the screw e cause decreasing arcs of movement of the lever c and therefore decreasing movements between the condenser plates. The screw e may alternatively bear on an extension of, or part connected with, the lever, and the lever may be a spring. In another form, two levers such as c may form the supports b, b<1> and movement be given by a screw engaging the side, or alternatively, the parts on which the links are pivoted may be moved. In another form, the support b may be eccentrically mounted on a rotary member, or arranged to be screwed along an operating screw to cause the tilting. In Fig. 5 is shown a support constituted by a ball i movable by a screw-operated member k to roll about other balls j, or alternatively the support b<1> might be moved.
