Title: Improvements in and relating to threaded spindle gears
IPC: F16H25/20
Filed: 1934-04-10
Abstract: 426,294. Screw-and-nut gearing. JERECZEK, V., 8, Wolframstrasse, Tempelhof, Berlin. April 10, 1934, No. 10781. [Class 80 (iii)] Drive is transmitted without play in a machine tool such as a milling machine from a spindle 4 to a table 10 by means of a second spindle 5 and helical gears 6, 7. A spur wheel 13 and the wheel 6 are fixed on the spindle 4, and the wheel 7 and spur wheel 14 are loose on spindle 5, but may be clutched thereto by a sliding dog 15. The nuts 2, 3 of the spindles are fixed in the frame. When power is applied in the direction of the arrow to the spindle 4, the wheel 7 being clutched to the spindle 5, the thrust of the teeth of the gears 6, 7 causes the threads of the nuts to be engaged as shown. The wheel 7 is then turned by the wheel 6 and the table 10 is moved to the right, the spindle 5 being held to the table by collars 8, 9. Play is eliminated by the axial action of the helical teeth. When the cutter 12 engages the work 11 it draws the table to the right and the righthand sides of the thread of the spindle 5 take the pressure. To prevent the piece 11 jamming under the tool 12 on reversal of the motion of the table, the latter is effected by reversing the motion of the spindle 5 by means of a handle 17 or by mechanical means. The wheel 7 is now not required and the spur wheel 14 is clutched to the spindle instead. Axial play between the spindle 5 and the table 10 may be eliminated by means of a bolt 19 having a collar 9 and slidable in a bore in the spindle and connected by a pin 18 to an adjustable collar 16, in which case axial thrust on the wheel 7 is taken by the collar 9. Instead of the arrangement shown the nuts 2, 3 may be secured to the moving part and the spindles to the stationary part; or both spindles and nuts may be carried by moving parts.

Apparatus for filling cans of fruit with syrup wherein a partial vacuum is created in the can for removing any trapped air comprises a rotating support 2 with elevator mechanism 9 to lift cans 4 to engage filler heads 7 which are supported in the bottom of a reservoir bowl 8 and partly immersed in the syrup. The filler heads each consist of a hollow body 12 arranged over an opening in the bottom of the reservoir 8 and fixed therein by a discharge valve seating 21 which passes through the opening. A lateral projection 14 from the hollow body is arranged to be below the level of syrup in the reservoir and is closed by an inlet valve 46 with ribs 48 which is operated via arm 56 by a cam 61 running on a track 62 and is so connected with the discharge valve 23 by the rocking arm 49 that when the inlet valve is open, the discharge valve is closed and vice versa. The discharge valve is operated by the rod 24 which has a striker plate 34 at its upper end which engages the normally open air valve 32 to close it and the normally closed vacuum valve 33 to open it when the discharge valve is opened. When in this latter state a plug 43 on the rod 24 closes a transfer port 41 so that syrup laden air drawn off by the vacuum is made to pass in a swirling motion into a jacket 37 through transversely inclined ports 38 so that the syrup in the air is deposited on the walls of the jacket. Further removal of syrup is obtained when the air passes through ports 39 again in a swirling motion before entering vacuum valve 33. The cam operating the inlet and discharge valves has a no can, no feed mechanism which comprises a hinged flap in the cam track which is raised either by mechanical or electrical means when no can is present to allow the can to traverse a different track whereby the discharge valve is not opened. Specification 712,842 is referred to.
