Title: Improvements in and relating to Rove Stop Mechanism for Spinning Machines.
Filed: 1901-04-13
Granted: 1902-04-10
Abstract: 7588. Fraser Automatic Rove Stop Co., and Fraser, J. April 13. Delivery, stopping; stop-motions. - Relates to mechanism in which, when the roving breaks, it is pushed aside by a weighted lever 1 from between the retaining-rollers 21, 22 and simultaneously held by the teeth 13 on the end of the detector lever 10. The weighted lever 1 carries a wedgeshaped piece 7, against the inclined face of which the end of the trigger 6 on the lever 10 engages. When the roving breaks, the lever 10 turns into the dotted-line position a, the trigger 6 sliding on the inclined face 7, and thereby allowing the lever 1 to fall. As the lever 1 falls, the inclined face 7 tends to force the trigger 6 further outwards and to cause the teeth 13 to engage more firmly with the roving. For piecing up, the lever 10 is turned into the dotted-line position b, when it forces back the lever 1 into the vertical position and engages with a notch 8 in the side of the lever 1, where it is held, by friction, thereby enabling the operative to use both hands for piecing up. The lever 10 is finally moved into the mid-position shown. The parts are mounted in pairs on adjustable brackets 14, which are provided with screws for adjusting the working positions of the levers 1 and are carried by a bracket adjustable on the frame of the machine. Above the rollers, the roving passes through curled or twisted guide-eyes 20 as shown.

Abstract: 21,701. Allen, R. Oct. 6. Feedwater, heating.-An apparatus for heating and cooling liquids and gases generally, and applicable also as a condenser and feedwater or air heater for a steam engine, is composed of a number of thin flat or corrugated plates b, Fig. 2 disposed one above the other and separated by frames a, which form distance-pieces. Suitable packing is placed between the edges of the plates and the frames, and the whole is closed by end covers d and secured together by means of bolts e. The spaces between the plates are connected together alternately, to form two distinct continuous passages through the apparatus, by means of ports g in the frames a. Preferably, these ports are arranged so that the liquids or gases can pass through the adjacent passages in a direction at right-angles to each other. Inlet and outlet connections to the separate passages are shown at h, i, j, k and filling-plates l, with bevelled ends, are placed between the plates to divide the currents passing through the spaces and force them into contact with the heating or cooling surfaces. In one modification, Fig. 4, the plates a are separated by solid bars or distance-pieces n and by perforated supports o which also serve to prevent distortion of the plates. The plates are enclosed in a castiron casing p, and the whole is secured together by bolts q. Webs are provided on the inside of the end covers of the casing to make the liquids or gases pass in a sinuous course. In a second modification, the tiers of plates and distance-pieces are cast in one piece and enclosed in a casing as before. When employed as a condenser and feedwater or air heater for a steam engine, the exhaust steam is passed through one set of alternate spaces, and the air or water, or both, circulated at right-angles to it through the other spaces. The invention is also applicable for warming buildings by passing steam and air through the two sets of spaces.
