摘要： 555,374. Stud fastenings. JOHNSON, L. W., and WILLIAMS, F. E. May 12, 1942, No. 6403. [Class 44] In a fastening device of the kind described in Specification 524,297 for securing together articles having registering apertures through which the device is passed, and comprising a tubular body 1 with a head 5 for abutment against one article, and balls 4 which can be projected radially to abut against the other article to retain the device in place, or allowed to collapse inwards to release the device under control of an axially movable member 6 within body 1, the body 1 has a bore of uniform diameter and the member 6 is positively moved between its two positions, in each of which it is retained by spring-loaded radial catches 12. As shown, the tubular bore 2 is closed at the left-hand end to exclude dust &c. the balls 4 are held captive in radial apertures 3 with reduced mouths, the rod 6 has a reduced end 7 which in the position shown allows the balls to move inwards, the rod 6 when moved to the left moving the balls outwards to project from the surface of body 1, and radial catches 12 surrounded by a spiral spring 15 engage in one or other of two grooves 9, 10 in the rod. The spring is covered by a sleeve forming the head 5. The rod is moved by a ring 8 which is slidably engaged in a slot in the end of body 1 so that rotating ring 8 rotates the whole device, if necessary to loosen it in the apertures. The invention is also applicable to the devices of similar type described in Specifications 554,307 and 555,041.

摘要： 527,422. Fountain pens. MABIE, TODD, & CO., Ltd., JOHNSON, L. W., and SEARS, E. S. March 6, 1939, No. 29499. Divided out of 514,513. [Class 146 (iii)] In a self-filling fountain pen, the supply of ink to the nib section 53 is controlled by opening or closing the ink passage 57 to the feed-bar 55 by relative rotary movement between the barrel and rib sections 51, 53 effected through the cap. The main and secondary ink passages 57, 58 are connected by sloping shoulders 59, 66 in the sections 51, 53 forming a valve which is closed by screwing the cap (not shown) on to the threads 63. Passage 57 communicates with the feedbar channel 68 by a slot or hole 69 in the feed-bar which is limited in its movement by a nut 64 with cross cuts. In a modification, the cap has a knurled band engaging a similar band on the nib section, the screw threads being formed on the barrel section.

摘要： 479,937. Pencil holders. MABIE, TODD, & CO., Ltd., JOHNSON, L. W., and SEARS, E. S. Aug. 17, 1936, No. 22639. Addition to 399,592. [Class 146 (iii)] In a pencil holder according to the parent Specification a sleeve is provided to act as guide for the lower end of the collet and derives its functional movement in both directions from the collet, and is slidably mounted and symmetrically supported in a member rigidly secured to the lower end of the pencil lining or casing and is formed with stops to coact with the member to limit the functional longitudinal movement of the sleeve. The collet 2 is formed with a reduced split lower portion provided with serrated jaws 45. The sleeve 1 is split at the upper end so that, by pressing the split sections together, it car be introduced into the bore of a collar 3, ir which it slides between limits provided by its flanges 42, 43. The collar 3 is secured to a lining 5, and is threaded at 11 for the attachment of a split tip 13. The rear end of the collet lies in a bore 25 in the end of a lead magazine 28. The magazine is closed by a socket 33 for a rubber 38a, with which socket engages the metal lining 40 of a cap 39. The collet is pressed rearwardly by a spring 22 arranged between discs 19, 20, and the movement is limited by a ledge 36 on the lining 5 engaging the socket 33. The rear end of the lining 5 is spun over to retain a pocket clip, (not shown). In a modification leads are stored between an inner star shaped lining 47 and an outer lining 48, and are introduced into the collet through a bore 57 in an operating knob 46. Rearward movement of the collet is arrested by the engagement of a ledge 53 or protuberances on the lining 47 with the disc 20. In either construction during the forward movement of the collet the sleeve 1 is carried by frictional engagement and the lead is fed until the sleeve is arrested by engagement of the flange 42, and collar 3. During rearward movement the lead is retained by the tip 13 and the collet is again clamped to the lead when the flange 43 on the sleeve meets the forward end of the collar 3.
