A water-tube, H.P. boiler a delivers steam to a turbine c which exhausts into a condenser d. The L.P. generator b which forms a feed-water reservoir also delivers steam to the turbine c and also steam to the heating-coil h of an evaporator e which provides distilled, make-up feed. The vapour from the evaporator e and condensate from the coil h pass into the condenser d the condensate from which is pumped through a feed water heater x to the boiler b. Water from the boiler b is forced by a pump u through a feedwater heater w heated by steam led from the tur. bine into the boiler a. A reserve feed tank n is connected to the condenser d. The heater x may be heated by the exhaust from the pump u or other auxiliaries or by fiuid from a steam-jet ejector if such is used to withdraw air from the condenser.

Title: Improvements in and relating to machines for manufacturing cigarillos and the like
IPC: A24C1/10
Filed: 1924-09-29
Abstract: 234,692. Bargeboer, A. Sept. 29, 1924. Cigar-making machines. - In machines of the apron-rolling type for making cigarillos or the like in which the leaf wrapper 66 is conveyed to the rolling table 2 from a pneumatic receiver by a pneumatic transporter 14. the rear end of the wrapper 66 is gummed and prevented from curling during transportation by the engagement therewith of a revolving gumming brush 45. The transporter 14 is carried by two vertical arms, pivoted to the mchine frame, and actuated to move the transporter horizontally and vertically, through linkwork engaging cams on the machine shaft. That part of the transporter engaging the wrapper 66 comprises a hollow casing 14<1> having perforations 4 on its underface. The forward end 61 of casing 14<1> is rotatable about a spindle 62 the edge of the upper wall of this portion bearing against a part-cylindrical wall 63 to maintain the casing air-tight. In action, the wrapper 66 is laid upon and pneumatically held to the receiver (not shown) and the transporter 14 brought over it, the rear end of the wrapper being trimmed by a roller on a link carrying the transporter which presses the wrapper against a fixed knife on the receiver. At the same time a projection on the receiver engages the arm 59 of a three-armed lever 58, 59, 60, thus actuating ratchet-and-pawl mechanism 57, 56 whereby a spindle 44 carrying three gumming brushes such as 45 is rotated to bring one of the brushes into contact with the wrapper. The vacuum is then transferred to the casing 14<1> and the wrapper conveyed by the transporter 14 to the perforated rolling apron (not shown) lying over the, table 2. A cam-actuated plunger next descends into a pocket 64 containing filler tobacco, a hinged bottom 65 of the pocket being thereby opened and the tobacco transferred to the pocket 3 of the able 2. The hinged member 61 is also turned down thus pressing the forward end of the wrapper- 66 against the edge of the pocket 3. At the same. time an arm carried by the plunger presses down the lever-arm 60 thus rotating the spindle 44 and disengaging the brush 45 from the wrapper. The vacuum is then transferred to the space 2<1> beneath the table 2 the wrapper being thereby held to the rolling apron. The transporter 14 is finally moved back to the receiver and the rolling of the cigarillo effected by rollers mounted on one of the arms carrying the transporter. The brushes 45 are gummed during their rotation by contact with a roller 54 intermittently rotating in a gum reservoir 55 carried by the transporter 14. The spindle 44 may be oscillated instead of rotated and the brushes 45 may be made to contact with a gumming roller mounted on a stationary portion of the machine.
