Filed: 1946-02-14
Abstract: 636,456. Towelling dispensing devices. STEVENS, A. H. (Steiner Sales Co.). Feb. 14, 1946, No. 4611. [Class 18] A cover 25 for a towelling dispensing device is adapted to enclose the two upright plates 5, 6, supporting the dispensing mechanism and between which the supply roll 51 and take-up roll are disposed, the cover, when closed, positioning a member 33 to smooth the soiled towelling as it is withdrawn into the device on to the takeup roll. The towelling is fed from the supply roll 51 out through a slot 29 in the front of the cover 25 and back through a n opening 50 in the base 15 of the device so that a loop of towelling is formed below the device. The pivoted member 33, separating the supply roll from the soiled towelling, has arms 32 which are engaged by the base 23 of the cover, when it is closed, to press the top edge 40 of the member 33 on to the towelling as it is rewound by the take-up roll. Alternatively, the member 33 may have a rod extending through an opening on each plate 5, 6 to be engaged by brackets on the sides of the cover. Two members 41, 42 co-operate with the edge 40 and serve to smooth out the towelling as it is withdrawn. To attach the end of the towelling to the takeup roll it is necessary to open the cover so that the hand can be inserted through an opening 50 in the base 15 into the device to deflect the member 33. At the same time the cover hanging below the device serves as a loop measuring means when a fresh amount of towelling is introduced to the device, the towelling passing through the cover as it is closed and hanging in a loop below the device. The two upright plates 5, 6 are attached to a back plate 2 which has its edges 3 flanged inwardly to engage with the edges of the side of the cover and provide a tight fit. The base 15 is attached to the plates 5, 6 and is provided with an extension plate 30 to support the supply roll 51. A projection 85 serves to retain the towelling out of contact with the face of the cover.

Title: Improvements in blank or like feeding mechanisms
IPC: B21D43/24
Filed: 1920-02-17
Abstract: 139,187. Cameron Can Machinery Co., (Assignees of Cameron, W.). Nov. 19, 1917, [Convention date]. Pile tables and supports for sheet feeds; sheetseparators; pusher feeds for single sheets.-A sheet-feeding device which is especially applicable for feeding metal blanks to can-forming machines, and is adapted to eliminate the risk of a double feed, is constructed with means for reciprocating the pile of sheets to and from a suction separator alternately connected to a vacuum pump and to a relief port. The centres of the sheets are adapted to be engaged by the separators. The separated sheets are fed by pivoted dogs 56 carried by extensions 54 of feed bars 11 which also carry fingers 12, and are supported by a bar 14 laterally adjustable on a crosshead 13 reciprocated by cam and link mechanism 15, 16, 17, 18. The sides 19 of the magazine are also laterally adjustable for taking sheets of different lengths, and the front of the magazine is formed with a slotted bar 21 to which these sides are connected by bolts and nuts, and which carries a knurled sheet detaining device 23. The pile of sheets 25 is reciprocated up and down by means of plates 26 carried bv rods 27 which are connected in a manner which permits of lateral and vertical adjustment to a cross-head 28 reciprocated by a pitman 31 connected to a crankpin 61 which is adjustable in a slot 62 in a sprocket wheel 33 to enable the extent of the reciprocating movement given to the plates 26 to be adjusted. This movement is adjusted so as to be evenly situated as regards the plane of feed, and when the plates are in their lowest position, the weight of the pile is taken by a suction head 38 attached to a tubular member 29 by means of a screwed nipple 41. The tube 29 is secured by set screws to a bracket 36, and can be adjusted in the desired vertical position. As the cross head 28 reciprocates, it connects the sucker to a vacuum pump 48 in its lowest position, and to a relief port 44 when the pile has ascended to the position shown in Fig. 3, leaving the bottom sheet attached to the sucker. The fronts of the dogs 56 are normally raised by springs 57 to an extent which can be controlled by set screws which contact with the bottoms of the slots in which the dogs are pivoted. The dogs can yield as they reciprocate towards the rear of the pile, and they contact with the bottom of the pile as they do so. The sag which is given to the bottom sheet can be varied by adjusting the stroke of the pitman 31 as described above, or this can also be varied by employing plates 26 of various widths.

Title: Improvements relating to Aeronautical Instruments applicable also for other purposes.
Inventor: DARWIN HORACE
Filed: 1918-03-20
Abstract: 123,996. Darwin, Sir H. March 20, 1918. Anermometers and air-current indicators.-Consists in utilizing the differences in the static pressures of the fluid in the open ends of pipes placed in the surrounding fluid on each side of a ship or aircraft in indicating or measuring the leeway or the curvature of the path. The invention also consists in utilizing as an indication of the curvature of the path of a ship or aircraft, the centrifugal force of a mass of fluid (air or water) enclosed in a pipe or pipes connected to two static heads placed in the surrounding fluid as far apart transversely as possible. Fig. 1 shows diagrammatically an apparatus for ships adapted to give indications of leeway, curvature of path, or leeway and curvature of path combined. Pitot tubes P and static heads S are fitted on both sides of the ship and are connected by pipes W to differential manometers MP and MS. The diaphragms D of the manometers are respectively coupled by rods c to those of two co-axial manometers MP2 and MS2, constructed as shown on the left of Fig. 3. The tendency of the diaphragm of the manometers MP to depart from the central position due to differences of water pressure, is neutralized by compressed air admitted on the opposite side of the diaphragm of the manometer MP2 through air pipes a<1>, connected to a reservoir R, grooves d and e on the coupling rod c and bush in which it slides respectively, and air ducts f in the rod. The resulting pressures in the two compartments of the manometer MP2 are transmitted by air pipes a<2>, a<3> to a manometer M1 the hand of which indicates leeway only. Each compartment is formed with a small vent hole g to allow the air to leak out slowly. The manometer MS2 is similarly controlled by the manometer MS and connected by pipes to a manometer M2 which indicates leeway and curvature of path combined. The four air pipes may be connected to the four compartments of a manometer M3 in such a manner that the hand thereof indicates only curvature of path. Fig. 3 shows apparatus which indicates the curvature of the path. The double differential manometer shown on the right is placed below the water line and at the centre of the ship and is connected by four pipes W to two pitot tubes and static heads. The manometer and the pipes are full of water. One of the diaphragms D is controlled by the two pitot tubes and the other by the static heads so that the force required to keep the rod c in its central position is the difference of the difference of the two pairs of forces. By this means the error due to increase of pressure due to leeway or other causes is eliminated. Means for giving an audible signal when the ship or aircraft has departed from a straight course may be combined with the indicating apparatus.
