Patent GB-190913946-A (GB)
Title: Improvements in Automatic Firearms.
Inventor: KRNKA KARL
IPC: F41A3/26
Filed: 1909-06-14
Granted: 1910-03-31
Abstract: 13,946. Krnka, K. June 14. Breech actions, sliding breechblock.-In a known form of automatic gun the breechbolt is capable of a short rearward movement before it is arrested by the locking-member, this movement being communicated to a momentum block which, when the breechbolt is arrested, continues its rearward movement a n d thereby releases the locking- member. The present invention consists in applying the principle of this known mechanism to a gun having a rotary lock. The mechanism comprises a non-rotary bolthead a, a rotary locking-sleeve b, and a non-rotary controlling-member c. When the gun is ready for firing, there is a short space z between the bolt-head a and the locking- sleeve b, but the controlling- member c is pressing against the bolt-head. Thus, on the discharge, the bolt-head and the controlling-member are driven backwards the distance z; the bolt-head is then arrested by the locking-sleeve c, but the controlling-member continues its movement. During this rearward movement, the controlling-member c, in the construction shown diagrammatically in Fig. 1, rotates the locking- sleeve b by means of the screw connexion 2, and the bolt-head and locking-sleeve are then driven back to open the breech. In the construction shown diagrammatically in Fig. 2, the locking-lugs 1 are sufficiently inclined for the back pressure to turn the locking-sleeve; but this is prevented, when the controlling-member is in its forward position, by the engagement of lugs 2 on the member c with longitudinal slots 4 in the locking-sleeve. These slots are enlarged at the back 5 to allow the sleeve to turn when the controlling-member has moved rearwards. Figs. 3 and 5 show the invention applied to a rifle. The bolt-head, locking-sleeve, and controlling-member are all loosely connected together, so that during the operation of the gun they do not become entirely separated, but form, in effect, a compound breech-block. The controlling-member is made in two parts rigidly connected side by side as shown in Fig. 5, the outside part forming a handle as well as an abutment for the recoil spring e. The extractor g, Fig. 3, is mounted on the bolt-head and partakes of its initial movement.

Title: Improvements relating to Apparatus for Coating Metal Tubes.
Inventor: GREENFIELD EDWIN TRUMAN
IPC: C23C2/22
Filed: 1910-03-24
Granted: 1911-03-24
Abstract: 1924. Greenfield, E. F. March 25, 1909, [Convention date]. Coating-machines.-Apparatus for wiping and polishing the interior surface of metal tubes after treatment with a liquid coating-material comprises rolls 20 for automatically feeding the tubes forwards over a rod 34 carrying one or more flexible wipers 35. The rod, which is of greater length than the tube 5 to be wiped, is held at each end by corrugated clamps 30 which are pressed by springs 31 into engagement with the corrugated ends of the rod. As the tube advances towards the rod, the pointed end 36 of the rod enters the tube, and the end of the tube engages with the rollers 37, pressing the clamps back and releasing the end of the rod. When the tube has been advanced by the rollers 20 and is clear of the rollers 37, the clamps again engage with and hold the rod. The forward end of the tube then engages with the rollers 37 at the other end of the rod, the clamps at that end being pressed open, releasing the rod, and enabling the tube to pass completely off the wiper. The apparatus is applicable for use with the coating - apparatus described in Specification 7429/10. The Specification as open to public inspection under Section 91 (3) (a) describes also apparatus for heating the tubes before their treatment with the liquid coating- material, and refers also to the treatment of tubes other than metal.

Granted: 1911-05-11
Abstract: 3705. Sun Electrical Co., Rawlings, J. J., and Sweetser, G. Feb. 14. Thermal interrupters. - Relates to electric switches of the type in which a buckled spring plate is acted upon by an electrically-heated expanding-device, which pushes the plate over with a quick action and rapidly breaks an electric circuit, and consists in mounting the electric contacts b, b<1> upon the expanding element, and in constructing this element itself in the form of a bowed brass plate a heated by an open-wound coil h in shunt with the main circuit. The adjustable contacts b, b' are mounted in metal brackets b<2>, b<3> secured to the centre of the plate a, the bracket b<2> being in electric contact with the plate and the other bracket insulated. The bowed contact-plate d is fixed in position between two yielding fingers d<1>, which allow for the increased distance between the ends of the plate when in the straight position. A condenser e is arranged inside the hollow base, and its separate halves are electrically connected between the contact band the plate d, and between the contact b<1> and the plate d respectively, so as to take the spark when the current is broken at each contact. The bare heating-coil h is wound over insulating-material h<1> secured channel-wise to the edges of the brass strip. As shown, the device is arranged to make and break, alternately, two circuits, for example, sets of lamps used in advertising. In operation, one circuit is completed when the bowed-plate d rests against the contact b. The heating-coil is then operative, causing the strip a to expand and snap the plate d into contact with the terminal b<1>. This cuts out the coil h and completes the second circuit. When the strip a cools, the first circuit is again completed. The movement is continuous, and the periodicity may be changed by adjusting the distance apart of the contacts b, b<1>.
