Filed: 1976-07-08
Abstract: 1535290 Labelling apparatus DYMO INDUSTRIES Inc 8 July 1976 [8 July 1975] 28493/76 Heading B8F [Also in Division B6]  Apparatus for printing and dispensing labels 1 from a step-by-step indexed label ribbon 2 comprises a printing attachment 5 carried at the end of a lever 15 whose other end is coupled to a hand lever 14 through a spring 20 which bears at one end against the lever 15 and at the other end against the hand lever 14. The lever 15 is held captive in an initial position by a pawl 25 which is disengaged from its locking position by the hand lever 14 when the hand lever has completed a determined part of its travel. The pawl 25 is pivotable about an axis 26 and is held in its locking position by a spring 27. In this position a butt 36 of the lever 15 bears against a projection 35 on the pawl and prevents the lever 15 from pivoting about its axis 13. When the hand lever 14 is pulled upwardly, the spring 20 is compressed initially as the lever 15 is prevented from moving by the pawl 25. On completion of a given distance of travel of the hand lever 14, a cam 33 thereon lifts the pawl 25 and disengages it from its locking position. The spring 20 now causes the lever 15 to pivot about its axis 13 and press the printing attachment 5 against the printing table 4 while at the same time swinging the inking device 10, 11 out of the way. The label 1 is detached from the label ribbon 2 as the latter passes around an edge 8, the ribbon 2 being advanced stepwise by means of a rocker arm 6 and a clamp piece 7. During downward movement of the lever 15, the arm 6 pivots about an axis 26 and moves to the position shown in Fig. 5. When the hand lever 14 is released, a drive pin 31 pushes the arm 6 back to the position shown in Fig. 1 and during this return movement the ribbon 2 is pulled along by the clamp piece 7.

Title: Improvements relating to electrical toasting appliances
IPC: A47J37/06
Filed: 1946-09-26
Abstract: 621,155. Toasting-apparatus. METCALFE, C., DIVALL, R. W., and MARRS, T. J. D. Sept. 26, 1946, No. 28739. [Class 28(i)] An electric toaster has heating elements in the body and in the lid; closing the lid switches on the heaters and winds a clockwork timing mechanism which releases the lid after a prearranged time. The lid 2, Fig. 1, is hinged to the body 1 and urged open by springs (not shown). Pivoted to the lid are struts 36, the lower ends of which are guided in a slot 38, Fig. 5, in the body side plate 12. These struts 36 engage a pin 34 on a rack 32 which is moved forward as the lid is closed. The inclined end of slot 38 causes the struts 36 to lift clear of the pin 34 at the end of the stroke and so to release the clockwork timing mechanism which has been wound by pinion 31. The time delay is determined by a manual control, Fig. 7 (not shown), which varies the distance through which the escapement arm has to travel for each swing of the balance wheel. A bimetallic strip, Fig. 8 (not shown), readjusts, through a linkage, the setting of the escapement arm, to modify the timing according to the temperature of the heaters. The lid is held closed by a hook 50 engaging a wire 39, Fig. 4, which is held across the front of the toaster by pivots 40, 41, and which is bent back to enter a slotted arm 44. As the timing mechanism runs down, a lug 47 on the rack 32 lifts this arm 44 thereby rocking wire 39 out of engagement with the lid catch 50. The electric heating elements are controlled by a mercury switch 51 mounted in a pivoted carrier 52 which is tilted into a horizontal position by the end of the catch arm 49 when the lid is closed, and which falls back when the lid is released. To lock the lid closed without energizing the heaters, a knob 56 rotates a forked lever 55a which moves the switch casing 52 out of the path of the arm 49, and also moves rod 54 so that its ends engage a further catch 57 on the arm 49. The body may have a removable baseplate, and may be mounted on hinged legs so that it can be raised and used as a griller, the lid heater then being switched off by an auxiliary switch. Means may be provided to energize the heaters only when a slice of bread is in position. A spring grid may be provided to raise the toasted slice when the lid opens.

Abstract: 507,034. Apparatus for finishing boxes. MULLER, J. C. Oct. 4, 1938, No. 28778. Convention date, March 18. [Class 18] Boxes with hinged lids are thrust intermittently along a table with their lids open, the lid of one box is swung up out of the plane of the table and, whilst in this position, pressure is exerted on the outside of the lid walls to bend them inwards slightly to facilitate the subsequent closing down of the lid. The table comprises rails 13, 14 with guides 16 ... 18 for the bodies of the boxes, and the lid of the box being operated on rests on a pivoted plate 19 which is tilted by a forked lever 21 straddling the main driving shaft 23 and carrying a roller resting on a cam plate on that shaft. The front flange of the lid is pressed in by a curved pad 9 on a pivoted lever 47 which carries a roller resting against a cam plate on the shaft 23. Two other pivoted levers 27, 34 are actuated by cam plates on this shaft and act in the following sequence. Both levers are lowered and lever 34 alone is then raised so that a wedge 33 carried thereby is withdrawn from between spring-pressed arms 11, 12 pivoted on a cross-shaft 26 on lever 27 to allow the lower ends of the arms to press together the walls of the body and lid which are hinged together. As the lever 34 rises, hooks 45 thereon engage the upper ends of pivoted levers 8 connected to the shaft 26, and the lower ends of these levers press inwardly against the side walls of the lid against the action of springs 42. The presser pads attached to lever 8, 47 have curved contacting surfaces.
