Abstract: 683,815. Bottle washing and sterilizing machines. WEBSTER & CO., Ltd., R. W. Nov. 2, 1950 [Nov. 2, 1949], No. 28074/49. Class 138 (i). [Also in Group XXX] In a conveyer system comprising an endless belt running over sprockets, rollers or the like, two adjacent sprockets &c. between which the belt extends directly, are simultaneously reciprocated in a direction longitudinally of the belt extended between them, while the belt is running over them. The speed of reciprocatory movement of the sprockets &c., is preferably arranged so that the belt between them is alternately moving and stationary. A bottle washing and sterilising machine consists of an endless conveying member 2 comprising bottle holders, and a system of guide rollers 3-11 around which the member 2 passes. Frames 13 and 18 carrying rollers 5, 6 and 10, 11 respectively are reciprocated horizontally by a lever 15 pivoted at 16 and oscillated by eccentric 17. The reciprocation is such that the horizontal portions of member 2 between pulleys 5, 6 and 10, 11 are advanced intermittently while the remaining portions are advanced continuously, when a continuous drive of suitable speed is imparted to one of the fixed pulleys e.g., pulley 8. The bottles are fed into the machine at 1, pass continuously through processing baths at 4, 7 and 9 and are subjected to air jets or reciprocating brushes on the intermittently advanced sections, being unloaded at 12. 683,854. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Dec. 15, 1950 [Dec. 23, 1949], No. 30678/50. Class 138 (i). A windscreen wiper blade is attached to a wiper arm 2, Figs. 2 & 3, by means of a clip 4 provided with a chamber 5 into which the wiper arm end 7 is insertible through an opening 6 in a wall of the chamber, wherein the arm is interlocked with the clip by means of a spring which has a seat 11 for the arm and is loosely disposed in the clip and so shaped as to permit tilting of the seat during insertion and removal of the arm. The clip 4 which may be stamped from sheet metal has a slot 9 in its top wall to receive a keeper lug 8 on the arm end 7. The clip is pivotally connected to a channelled blade holder 15 by pintles 16 struck therefrom engaging in bearings 17 formed in the end walls 18 of the clip. However the clip may be fixedly secured to the blade backing. A flat spring is formed with the arcuate seat 11 and legs 12 bent downwardly and under the seat 11. The ends of the legs are cut square and co-operate with a flat supporting surface 14 on the holder 15. When the end 7 of the arm is inserted through the entranceway 6 the legs 12 permit the seat 11 to tilt as shown in dotted lines in Fig. 2. The spring finally adopts its full line position and urges the lug 8 into engagement with a shoulder 10 at the end of the slot 9. Also when the wiper is not in use the spring normalizes the blade on the windscreen surface. When the arm end 7 is disengaged from the clip the.spring is tilted as shown in Fig. 3. The clip is connected to the pintles as by springing one of the end walls 18 over a pintle. Reference has been directed by the Comptroller to Specifications 632,981 and 645,983.
