A bobbin holder comprises a spindle-like body 1 in which are housed two elongated legs 10 shaped at their lower ends to provide leg heels 10b. In Fig. 2, the heels 10b are shown biased outwardly from the body 1 by two off-set ramps 8. Surrounding the heels 10b is a heavy frustro-conical collar 9. When a bobbin 12, Fig. 4, is pushed on to the body 1 it raises the collar 9 which interacts with the heels 10b to raise them up the ramps 8 and cause them to retract into the body 1 until eventually the collar 9 is above the heels 10b. The heels 10b then drop under gravity and the ramps 8 bias them outwardly to support the bobbin 1 by engaging under a bobbin shoulder 12b. To remove the bobbin 12 it is pushed right up the body 1 to raise the collar 9 to a position at which it acts on upper leg projections 10a in a manner raising the legs 10 and causing them to swing inwardly until a toe 10d on each leg has been raised up its associated ramp 8 and on to a retaining ledge 8b associated with each ramp. The bobbin holder is then in the condition illustrated in Fig. 5 and the bobbin can be withdrawn from the body 1. As a bobbin is withdrawn the collar 9 drops under its own weight and collar abutments 9a, Fig. 3, (not shown), in passing, push the toes 10d off the retaining ledges 8b by engaging with humps 10c opposite the bobbin-retaining heels 10b. The bobbin holder is then, once again, as in Fig. 2.

Title: Improvements in and relating to moisture-proof packages
IPC: B65D75/38
Filed: 1922-07-27
Abstract: 196,849. Alexander, A. E., (Stokes & Smith Co.). July 27, 1922. Packeting by wrapping-up: packing food products, tobacco, &c.-Relates to packages in which a wrapper coated with adhesive and rendered moisture proof is applied to a box or carton of pasteboard &c. containing food products, tobacco, &c. A wrapper B, Fig. 2, comprises four portions a, b, c, d to fit the sides of the carton C, Fig. 7, and is coated on the inner side with a layer V, Fig. 5, of varnish and with a layer W of wax. The layer of varnish is relatively thin, and the layer of wax may be of substantial thickness. The wax may contain resin, celite, and cotton oil, in which case the layer of varnish may be omitted. The wrappers may be applied to the cartons by the machine shown in Fig. 15. The wrappers are stacked in a pile S on a movable base 19 and are separated by a pusher roll 21 to pass between feed rolls 22, 24 to an adhesiveapplying roll 26. The roll 26 is supplied with the adhesive W from a trough 28 with a waterjacket 29 heated by electrical means 30. Stripper plates 31 disengage the blank from the roll 26 and the forward edge is seized by a gripper 17 on an intermittently rotating turret 12. The wrapper is then in correct position relatively to a pocket 14 having a movable side 15 and a plunger bottom 41. A plunger 38 thrusts the lowermost carton C from a hopper 35 into the pocket, carrying the wrapper with it and making the folds shown in Fig. 7. The sides a, b are folded into contact with the corresponding sides of the carton and the flaps m are turned up by spring pressed members 42. According to one method, the adhesive W may be sufficiently soft for the folding operations to ensure that the wrapper and carton adhere, but electrical heating elements may be disposed in the turret near each pocket and current may be supplied over a part of the travel of the turret from a stationary contact strip 50. Heat is thus supplied by conduction and radiation to the sides and bottom of the pockets 14 and to the end members 42, causing the folds shown in Fig. 7 to adhere to the carton. A movable blade 55 folds down the strip p and a heated pressing plate 60 folds down the top side c, the wrapper and carton then being as shown in Fig. 9. Water jackets 65, 66 cool the adhesive to ensure proper setting and an ejecting mechanism 76 actuates the plate 41 to thrust the partially wrapped packet from the pockets between conveyer belts 80, one of which has spaced projections 85 for engaging the packets. Spring pressed plates 86, Fig. 17, fold down the end flaps k and stationary flap-folding plates 87, 88 turn up the flaps h, g. Heating elements 90 ensure the adhesion of the end flaps and cooling jackets 96 secure the flaps in place, after which the packets are ejected. It is stated that sufficient of the adhesive adheres to the carton to provide a moisture proof envelope even in the event of the wrapper being broken.

Title: Apparatus for coating with metal by dipping
IPC: C23C2/06
Filed: 1935-07-19
Abstract: 459,925. Coating with metals. WILLIAMS, F. C., 22805, Michigan Avenue, Dearborn, Michigan, U.S.A. July 19, 1935, No. 20630. [Class 82 (ii)] [See also Group XII] Apparatus for coating articles, e.g. plates, piping, beams, &c., with metals by dipping comprises two receptacles, one for the coating metal open at top and bottom and disposed inside the other which contains a metal of higher specific gravity. The outer receptacle is surrounded by a casing and is heated by hot gases which enter the casing through an inlet adjacent the upper end of the receptacle. An outlet for the gases is provided adjacent the inlet and direct communication between the inlet and outlet is prevented by the provision of a horizontal baffle and vertical baffles extending downward from the horizontal baffle over a substantial length of the outside of the receptacle on opposite sides thereof, the baffles closing the space between the receptacle and casing. The apparatus shown in Figs. 1 and 3 comprises a receptacle for molten lead consisting of a small lower part 6 and a larger upper part 8 in which the pot 7 containing the coating metal, e.g. zinc, is suspended. The pot 7 is suspended from rails 11 and can be moved by means of a motor 18 and chain 16 so that it is either above or out of line with the lower part 6 of the lead bath. In operation the pot 7 is moved out of line with the part 6 and the article is passed down through the molten lead, which is covered with a flux layer. The pot 7 is then moved back so that it is directly above the part 6, and the article is withdrawn through the metal in the pot 7. The lead bath is enclosed in a casing and two pairs of vertical baffles 23 and 24 are provided extending from the part 6 to the casing and terminating short of the bottom of the part 6. A baffle 37 is provided, in line with one of the baffles 23, between the part 8 and the casing and extending to the top of the casing, and the baffles 24 are extended upwardly along the sides of the part 8 as far as a horizontal partition 32, which extends around half of the periphery of the part 8 and divides an opening in a wall of the casing into an inlet 33 and an outlet 34. Hot gases are introduced through the inlet 33 and flow downwardly through the passages formed by the baffles on the side of the receptacle remote from the inlet and up through the passages on the near side to the outlet 34. The gases passing through the outlet 34 are withdrawn by a pump 47 in which some of the gases are released and the remainder returned to a passage 46 communicating with the inlet 33 where they are mixed with gases from a burner located in an aperture 44. In the form shown in Fig. 4, the articles are not passed through the lead in the bath 53, but are passed through the zinc in the bath 52 by rollers 54, and guides 57, the guides being formed of a plurality of horizontally spaced bars. The guides converge towards the rollers 54 and a flux box 59 is provided at the entry end. The lead bath 53 is heated in the manner described above.
