In a mattress-filling machine, the combination with a forming-chute, a delivery hopper adapted to receive the filling-material and to deliver the same into said chute, and feeding and packing mechanism operating to receive the material from said hopper and to feed and pack the same into and through said chute. (15.) In a mattress-filling machine, the combination with a forming-chute, a reciprocating plunger operating therein to successively compress increments of the filling-material into said chute whereby said material is progressed through said chute in condensed and compressed condition to be received in a cover to form a mattress. (16.) In a mattress-filling machine, the combination with a forming-chute, a reciprocating plunger operating therein, means for adjusting the width of said chute, and means for correspondingly varying the width of said plunger to regulate the width of the mattress to be produced. (17.) In a mattress-filling machine, the combination with a forming-chute, a reciprocating plunger operating therein, said chute being curved at a point adjacent to its delivery end to afford resistance to the action of the plunger, whereby the density of the filling-material may be regulated. (18.) In a mattress-filling machine, the combination with a forming-chute, a reciprocating plunger operating therein, a hopper delivering into said chute, said plunger operating past the delivery edge of said hopper, the delivery end of said chute adapted to receive a mattress-cover thereover, whereby the filling-material is compressed or condensed into and progressed through said chute, and is delivered in condensed and compressed condition into the cover. (19.) In a mattress-filling machine, a vertically arranged forming-chute, a plunger operating therein, the lower or delivery end of said chute being curved or bent outwardly. (20.) In a mattress-filling machine, the combination with a forming-chute, the sides of which are capable of adjustment towards and from each other to vary the width of the mattress to be produced, a plunger operating therein and comprising plates or slats, said plates or slats being connected together by lazy-tong levers, the outermost ones being connected to the adjustable sides of the forming-chute, whereby when said sides are adjusted the width of said plunger is also and correspondingly adjusted. (21.) In a mattress-filling machine, a framework, a pair of vertically arranged forming-chutes, a plunger operating in each of said chutes, a single drive-shaft, and gearing operated thereby for actuating both of said plungers. (22.) In a mattress-filling machine, a forming-chute, a plunger operating therein, a drive-shaft, a pitman eccentrically connected to said shaft and to said plunger, whereby when said plunger is operated the filling-material is compressed into and progressed through said chute in condition to be received in a cover.

No. 15299.-22nd August, 1902.-WILLIAM HARVEY, of Albert Street, Auckland, New Zealand, Manufacturer. An improved straining-pan for milk and other fluids.

Claim.-A straining-pan having the bottom thereof shortened so as to leave an opening between its shortened end and the under edge of the outer wall of pan, and said opening covered with a fine-wire mesh or gauze or other netting, having an inner wall preferably curved flush at its top with top of outer wall, but shorter than it, and a projection above shortened end of bottom of pan, and fine-wire mesh or gauze or other netting stretched from lower end of inner wall to said projection, and both meshes respectively, or one mesh if one only is used, soldered or otherwise suitably secured to the bottom of the inner wall, the top of the projection, and the under edge of the outer wall, for the purpose set forth, substantially as described and illustrated.

No. 15302.-26th August, 1902.-DEMETRINS SEYMOUR, of Bridge Street, Spit, Napier, New Zealand, Coppersmith. Improvements in siphons.

Claims.-(1.) In a siphon used for drawing off liquids from vessels, a cup mounted on a branch pipe at the top of the siphon, substantially as and for the purposes set forth. (2.) In a siphon used for drawing off liquids from vessels, a cup mounted on a branch pipe at the top of the siphon and a cock in the said branch pipe, substantially as and for the purposes set forth. (3.) In combination with a siphon for drawing off liquids, a branch pipe at the top of the siphon, a cock in the branch pipe, a cup mounted upon the branch pipe, a cock on the longer leg of the siphon, and an extension of the pipe below this said cock, substantially as and for the purposes set forth. (4.) The combination and arrangement of parts comprising my improvements in siphons, substantially as and for the purposes set forth and as illustrated.

No. 15309.-27th August, 1902.-DAVID TOWNSEND SHAPLES, of 120, Dean Street, Westchester, Pennsylvania, United States of America, Superintendent of Dairy-apparatus Works. Improvements in process and apparatus for mechanical milking.

Claims.-(1.) The process of milking mechanically according to which collapsible cups enclosing the teats are caused to pulsate with automatically varied frequency or intensity corresponding with the varying freedom of the milk-discharge from the cow, substantially as described in connection with the drawings. (2.) The described process of milking mechanically which consists in automatically varying the teat-cup pulsations by increasing suction thereon to a maximum with more or less rapidity, determined by the varying freedom of the milk-discharge, and thereafter decreasing the suction to a minimum, substantially as set forth. (3.) The described process of milking mechanically which consists in automatically varying the teat-cup pulsations, both as to the frequency or rapidity of the teat-cup movements cutting off communication between the teats and the udder and as to the intensity of the succeeding teat-compressions, in accordance with the varying freedom of the milk-discharge, substantially as set forth. (4.) An automatic teat-cup pulsating mechanism for a milking-apparatus characterized by an air-chamber arranged in communication with the teat-cups and with the conduit-tube and a relief-valve in said chamber arranged to open automatically at a determined maximum pressure and to close automatically at a determined minimum pressure, thereby producing corresponding teat-cup pulsations, substantially as set forth. (5.) In an automatic teat-cup pulsating mechanism for a milking-apparatus as described, the valve mechanism located at the junction of the teat-cups with the conduit-tube, and arranged to be directly actuated pneumatically at automatically varied intervals, substantially as set forth. (6.) In an automatic teat-cup pulsating mechanism for a milking-apparatus as described, the air-chamber arranged in communication with the teat-cups and provided with connected air-inlet and milk-outlet valves, having limited independent spring-controlled movements automatically actuated pneumatically to produce corresponding pulsations of the teat-cups, substantially as set forth. (7.) In an automatic teat-cup pulsating mechanism for a milking-apparatus as described, the conduit-tube for both air and milk, having its passage-capacity limited to substantially the maximum milk-flow so that the flow of air will be in inverse proportion to the flow of milk and the intervals between pulsations thereby automatically regulated by the volume of the milk-flow, substantially as set forth. (8.) In an automatic teat-cup pulsating mechanism for a milking-apparatus as described, the connected relief and check valves, having limited independent movements and co-operating to automatically regulate the length of intervals between pulsations, substantially as set forth. (9.) In an automatic teat-cup pulsating mechanism for a milking-apparatus as described, the teat-cup characterized by relatively stiff wall portions arranged to concentrate the pressure thereon, and thereby produce a hinge-like collapsing movement thereof, affecting mainly a desired portion of the cup, substantially as set forth. (10.) In a milking-apparatus substantially as described, the arrangement of the milk-receptacle in connection with the overhead air-service pipes at an elevation above the cow, and with the milk-tube depending therefrom and carrying the teat-cup mechanism, substantially as set forth.
