摘要： 767,351. Drawing-pens. ANDERSON, W. W. Oct. 10, 1955 [Oct. 11, 1954], No. 29197/54 Class 97(3) A drawing pen comprises a tubular handle 3 with a pair of resilient nibs 5 at one end, a blade 6 extending from between the nibs into the handle and a plunger 7 which forms part of, or connected to, the blade and is spring urged outwardly from the other end of the handle whereby the blade may be reciprocated between the nibs to clean them. In the form shown the nibs are formed on a sleeve 4, the inner end of which forms an abutment for one end of the spring 8. The other end of the spring bears on a collar 9 on the plunger 7, the movement of collar and plunger being limited by a bush 10 screw-threaded into the handle and provided with a knurled head 11. The setting of the knurled head, which may carry a scale, controls the working spacing of the nibs 5. Alternatively the spacing may be controlled by a screw between the nibs accom modated in a slot in the blade 6. The blade passes through a seal 14 of rubber &c. which pre vents ink from entering the handle.

摘要： 624,679. Electric motors. ANDERSON, W. W. March 17, 1947, No. 7282. [Class 35] A toy commutator motor has two or more rotors on the same shaft 4, each rotor having a plurality of salient poles 10 which are staggered with respect to those on the other rotor, and each carrying a coaxially-mounted annular exciting winding 9 intermittently energized by an interrupter mounted on the shaft, engaging a stationary brush or brushes, the stator poles comprising a series of equally spaced longitudinal iron bars 2 arranged parallel with the rotor axis. Each core comprises a laminated boss 7 carrying the coil 9 and placed between groups of laminae 10 shaped to form three salient poles, the whole core being secured by retainers 11. The interrupters comprise cup-shaped metal members with their peripheral surfaces cut away to leave three conducting segments 15, and in the machine shown, these segments are interdigitated and mounted on a laminated insulated bush 16. A pair of bush contact strips 24 are energized from the main terminal 20 and mounted on a pivoted member 25 to enable either direction of rotation to be obtained, the current returning through the machine frame. It is stated that three or more rotors may be assembled onto one shaft.

摘要： 748,229. Spray-producers &c. ANDERSON, W. W. June 25, 1954 [May 26, 1953], No. 14603/53. Divided out of 747,619. Class 69 (3). Water fed to a pipe 20 flows through a venturi throat 29 to a spraying nozzle, not shown, and a portion of the flow passes through a passage 22 into a closed air vessel 21. The air displaced in the vessel passes through a valvecontrolled passage 24 to a container 23 of liquid insecticide &c., and the insecticide is delivered via a, passage 28 controlled by a valve 30 to the main water stream. A float-operated valve 26 prevents the entry of water into the container 23. By closing the valve 30 and a valve 32 in the pipe 20 paint or whitewash &c. may be delivered from an outlet 33 of the liquid container under air pressure. Specification 747,619 is referred to.

Class 106 (2) An instrument for comparing or measuring the tension of powertransmission belts comprises a pair of telescopic and spring-loaded parts a, b, one or each of them having at one end a longitudinally adjustable abutment p, and means h, e, for indicating relative movement of the said parts. The parts a, b may be of tubular form, the outer part a carrying a scale e on which is pivoted a spring-loaded pointer h ; the inner part b having a tongue f in engagement with the pointer h. Lock nuts q are provided for use when setting the abutments p at the required distance apart.

摘要： 773,612. Drawing-pens. ANDERSON, W. W. Sept. 13, 1955 [Sept. 14, 1954], No. 26558/54. Class 146(3). [Also in Group XX] In a drawing-pen comprising a pair of relatively adjustable nibs a interconnected by an adjusting- screw b, a thin longitudinallyslidable blade c is situated between the nibs for the purpose of removing congealed ink from between the points of the nibs, the blade being supported between a pair of resilient guide blades g. As applied to a reservoir pen, the reservoir f is a transparent plastic tube sealed at one end by a rubber &c. plug i and screw-threaded cap j, and at the other end has screw-thread engagement with the head portion f 1 , abutting a rubber &c. bush k having a hole therethrough which can be closed by a tapered part e 1 on the stem e of the blade c. Ink flows around the stem e and enters a semicircular space between the blades g when the blade c is pushed outwardly; when the blade c is retracted, a slot therein enters this space and is filled with ink which is fed towards the outer ends of the blades g when the blade c is again moved outwardly. The guide blades g may consist of a folded metal strip having flattened, splayed outer ends. The blade c has laterallyprojecting finger pieces. The blade tip can be pushed level with the tips of the nibs a to enable thick lines to be drawn. For drawing wide lines, nibs having transversely-extending tips a 1 can be used : for writing figures, the nibs are so shaped that together they form a tapered tube cut off obliquely at the writing end. The nibs are detachably-secured to the head f 1 , their shanks a 2 being of half-sleeve form and provided with projections a3 which fit into gaps f 2 in the head f 1 .

摘要： 735,919. Driving chains. ANDERSON, W. W. July 13, 1954 [April 20, 1953], No. 10716/53. Class 24. A chain consists of alternate links each formed by a pair of similar plates 3 arranged parallel with each other and interconnected at their ends by pins 4 riveted thereto and shaped to provide slightly rounded edges 4b which face each other, and interconnecting links each consisting of one or more plates 5 having at each end an inturned hook forming a notch 5a to receive the edge 4b of the associated pin 4. The shape and size of the links are such that they interlock one with the other, and can be separated only by removing them one at a time from either end of the chain.

摘要： 665,228. Brush-gear for dynamo-electric machines. ANDERSON, W. W. June 22, 1950 [July 6, 1949], No. 17832/49. Class 35] In a small motor, the brushes are moved by commutator friction into the optimum position for each direction of rotation. The motor comprises a field magnet b, c, excited by coil d, and an armature a whose spindle carries a cooling fan e and a disc-type commutator g. The holders m which carry the carbon brushes are carried on springy strips to which the connection is made and which have loops n and ends o which rest against an insulating carrier-plate i. The plate is slotted at k to accommodate the spring and the sliding movement of the brush is conveniently limited by having it sliding in a wider slot of shorter length.

摘要： 700,919. Belt fastenings. ANDERSON, W. W. Nov. 8, 1951 [Jan. 8, 1951 ; May 24, 1951] Nos. 493/51 and 12147/51. Class 80 (1) A fastener for driving belts comprises looped metal links a which are attached to the belt ends by inturned fangs (not shown) and/or spikes i and are interconnected by a left- and right-hand threaded shank f passing through slots in the V-shaped loops of the links and engaging crosspieces g, liners h being provided between the cross-pieces and the loops. The spikes i may be fluted and may be staggered, and the links a are preferably curved for passing round the pulleys. Set screws g 1 lack the shank f. The first Provisional Specification describes also belt fasteners wherein liners are omitted, the links may be U rather than V-shaped and may be stepped to abut a belt end, and one-piece H-shaped interconnecting members may be employed. The second Provisional Specification describes a fastener wherein only one link is slotted the other being headed and being passed through the slot and turned to lock.
