IPC: F16F7/04
Filed: 1922-02-06
Abstract: 174,953. Blackmore, C. C. Feb. 7, 1921, [Convention date]. Cone and disc; actuated by springs.-In a shock-absorber for vehicles, the fixed and movable members are so connected that the frictional resistance to movement of the movable member increases progressively during its movement. The fixed base 1, Fig. 2, is secured to the vehicle frame and has a raised bearing-surface 3 provided with an annular friction element 4, which is embraced by the flange 7 of a movable member 5 forming part of a housing 8. Between the outer part of the housing and the base 1 are arranged a number of springs 9 which in the normal position are substantially parallel to the axis of rotation, so that their tension is increased during rotation, causing the friction surfaces to engage with progressively increasing pressure. The springs are connected to the eyes 11 of bolts 10 passing through the members 1, 8, nuts 12 serving for screwing up the bolts for tensioning the springs before locking the bolts. Washers 13, preferably of U-form, allow subsequent adjustment. A screwed cap 14 provides access to the springs. In a modified form shown in Fig. 4, the housing is formed in two parts 15, 18 outwardly screwthreaded in opposite directiors and held together by an inwardly screwed collar 19. The friction element 28 has also an oblique contact surface engaging an oblique surface 16 on the member 15, the transverse portion of which is substantially in line with the inner surface of the element 28, thus allowing the springs to be mounted further from the centre. A wedging action results from the oblique arrangement of the contacting surfaces. The member 5 is connected to the axle through a rod universally jointed at the ends to an arm 20 and to a stud clamped to the axle.

Abstract: 414,422. Wrapping-machines. PARRY, F., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Feb. 9, 1933, No. 3977. [Class 94 (i).] The machine assembles a number of articles into a composite batch and wraps them in a single wrapper, or wraps single articles. As shown, twenty-four articles are assembled into two columns each containing three rows of four articles to form a rectangular assembly. The articles 1, Fig. 1, are delivered from two parallel channels 2, of which one is shown, on to plates 3. A plunger 4 pushes the articles on to tables 8 until two rows of four articles each are in position, whereupon the tables are lifted by rods 9 to raise the articles to the level of an assembling table 13, Fig. 4. Catches 14 support the articles when the tables 8 fall again and three rows are superimposed at each side of the machine. The catches are moved out of the path of a row of ascending articles by cams 15. Plungers 18 approach and form the two batches into a single assembly C on the table 13. A plunger 21, Fig. 1, feeds the assembly, which now acts as a single rectangular body, to the right, carrying with it a wrapper cut from a web 22, to which adhesive has been applied if desired by a roll 24. The wrapper is steadied in position by guides 123 which move laterally out of the way when the plunger 21 makes its working stroke. The wrapper is folded on to the top and bottom of the assembly by rollers 26, and the rest of the folds, with the possible exception of the first tucks 28, Fig. 12, are made while the assembly is stationary on a plate 27. The first tucks are made by folders operated by cams 30 to move inwardly to meet the oncoming article and then to move with it to the stationary position and to remain in position while the next fold is made. Alternatively, the folders may move after the article has reached the stationary position. The lower side folds 33<a> are next turned upwards by folders 34, Fig. 1, which remain in position until the upper folds 37 have been turned down by folders 38. The end folds 41, Fig. 12, are made by folders 42 and the bottom and top folds in succession by folders 46, 50. All the folders are controlled by springs and the article is held firmly on the table 27 by a brush 55. The package is pushed by the next succeeding batch into a collector 53 which may have heaters 54 to dry the adhesive. When single articles are to be wrapped, they may be fed from one channel to the wrapping position, or alternately from two channels.
