Title: Method of and apparatus for applying protective partitions  between glass containers and the like as the containers are  being coveyed in massed ranks toward a loading area and parti tioning structure
IPC: B65B5/06
Filed: 1971-05-17
Abstract: 1346429 Applying protective partition strips between groups of containers CLEVELAND PARTITION CORP 17 May 1971 [10 June 1970] 15362/71 Heading B5D [Also in Division B8] In a method of applying protective partition strips to preselected n umbers of moving containers 14, made of glass, or the like, preparatory to packaging as separate units, interconnected ribbons 22 of die-cut disconnectible, longitudinal partition strips of paperboard material, or the like, are re-rolled on a drum 16 and are then fed, from the drum, in substantially laterally aligned relation, into vertical protective positions longitudinally between moving lines of containers 14, transverse partitions 34 being disposed successively between the advancing ranks of containers and into assembly engaging-positions with the ribbons 22 to provide separable, packageable, units. The roll is perforated at 23 to provide connected, end-to-end, partition strips 24 adapted to separate and protect six parallel rows of containers in a packet; has, preferably transversely offset, uncut, tearable tab portions 25 which maintain the ribbons 22 in aligned rotation during re-rolling after die-cutting; and is die-cut to receive the transverse partitions 34. As the roll is unwound it forms a loop the weight of which causes knife edges 31, at the upstream ends of five corridor panels 26, to cut the tabs 25 and separate the ribbons 22. The latter are turned through 90 degrees in the corridors for edge-wise travel down a ramp 30 into separating positions between parallel containers 14 which are fed, in coinciding parallel rows, from below the ramp 30, which may be provided with guide posts, straps, &c. The roll may be unwound by conventional power mechanism to maintain the loops. A power-actuated blade 36 successively drives transverse strips 34 into engagement with the aligned transverse cuts in the partition strips 24 between ranks of the containers 14 in timed relation with the containers, strip 34 being inserted at the transverse cuts aligned with the perforations 23. As a batch of twenty-four containers reaches a stop board 44, a poweractuated ram 46 moves them transversely into an open ended carton 40 brought into position on a conveyer belt 42. The action of the ram 46 may tear the perforations 23, some paperboards however may need to be separated by a blade 48. The actions of the blades 36, 48 serve to effect the longitudinal travel of the strips 34. In a modification, Fig. 5, not shown, the transverse strips 34 are inserted across the strips 24 by means of a vacuum system.

Title: Hardness measuring apparatus
IPC: G01N3/00
Filed: 1959-05-06
Abstract: 899,461. Testing hardness of materials. ERNST, A. May 6, 1959 [May 13, 1958], No. 15593/59. Class 106 (2). A hardness measuring apparatus in which a pre-load is followed automatically by the main load comprises a penetrating tip 7 driving a measuring instrument 14, means 4 for applying the main load and a damping device 1 to slow down the application of the load at the moment the tip comes into contact with the material. The apparatus is supported on the surface M to be tested by a base 17 to which is attached the hydraulic damper 1. The casing 5, to which is fitted an outer member 18, is normally held above the base 17 by a spring 22 and is provided with a dial indicator 14, which may be hydraulically driven and a hand grip 20. The indentor 7 slides in an extended portion 50 of the casing and actuates the indicator 14 through a linkage 8, 11, its stem also abutting a member 9 connected to the plunger 60 of the damper 1. The apparatus is used in the following manner. It is placed on the surface M and the grip 20 pressed downward until flanges 21 on the outer member 18 contact the base 16. The indentor 7 is then resting on the surface under the preload of a spring 23. At this moment the reading on the indicator 14 is zero, as the member 11 which is slidably connected to the member 8 and is limited to movement between two abutments 12, 13 formed in the casing, is then resting against the upper abutment 12. Since the piston rod 60 of the damper 1 is being held up by the pressure of the oil therein. the spring 4, which is the main force-applying element, has been compressed. It now acts against the damper 1, gradually pressing the member 9 downwards and hence applying an increasing force to the indentor 7, the depth of penetration of which is shown on the indicator 14. The apparatus may be mounted on a support and urged against the workpiece by any desired means, thus allowing automatic zero-setting and load-application.

Title: Improvements in or relating to brakes for vehicles
IPC: F16D65/46
Filed: 1940-10-28
Abstract: 542,713. Internally expanding brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and PARNELL, F. G. Oct. 28, 1940, No. 15789. [Class 103 (i)] In a brake in which a pair of shoes are applied by a fluid pressure cylinder disposed between one pair of shoe ends and the shoes turn about fulcrum at the other ends, the fulera are adjustable relatively to each other and a parking brake applying means acts on the shoes at or near the ends upon which the cylinder acts, whereby the relative position of the points of connection of the parking means to the shoes is substantially unaltered by the shoe adjustment. In Fig. 1, the fulcrum of the shoes comprises a socket 23 fixed to the anchor plate and a tappet 25 screwed into a sleeve 24 having a flanged end 26 which abuts on the socket and by which the sleeve can be turned to effect adjustment. The base 29, 30 of slots formed in the ends of the tappet and socket to receive the shoe ends are convex for engagement with corresponding surfaces of the shoe ends. The hydraulic cylinder 12 is slidably mounted on the back plate by a spigot and slot and its end and that of the piston 16 have slots similarly to those in the parts 23, 24. The end of the shoe 14 that bears on the cylinder is plane and that of the shoe 13 that bears on the piston is concave and thus locates the cylinder against turning about its centre. The hand or parking brake linkage comprises a strut 31 the slotted ends of which engage the shoes and a lever 33 pivoted to the shoe 14 and engaging a projection 34 on the strut. The lever is operated by a cable 35. Adjustment is effected by turning the member 24 until both shoes are applied, the shoe 14 through the piston and cylinder, and then slacking back the member 24. When the brakes are released after an application following an adjustment, the cylinder 12 does not move but the drum centre which has been displaced slightly to the left due to the greater pressure of the shoe 13 which with the normal direction of drum rotation is the leading shoe, returns so that the drum moves away from the shoe 14 and thus centralizes the shoes. In a modification, Fig. 3, the shoes are fulcrummed as in Fig. 1 and the cylinder 36 is slidably mounted in the back plate 10 and acts on the shoe 13 but the piston acts on the shoe 14 through a plunger 46 which together with the piston is slotted at 47, 48 to receive the end of a handbrake lever 52 pivoted at 53 to the cylinder. Operation of the lever thus moves the plunger and cylinder in opposite directions without moving the piston in the cylinder. The cylinder slides in a slot 37 and has shoulders 38 and end projections 41 which engage the inner and outer faces of the back-plate and is attached by passing one end projection through the slot sliding the cylinder to the end of the slot, passing the other projection through the slot and then centralizing the cylinder.

Abstract: 354,871. Ink-ribbon mechanism. ADDRESSOGRAPH CO., 901, West Van Buren Street, Chicago, U.S.A. May 22, 1930, No. 15809. Convention date, March 13. [Class 100 (iv).] Feed and automatic reversal.-In mechanism comprising a reciprocating spool-actuating member which is caused by means of an over-centre spring device to co-operate with the spools alternately, the reciprocating member and a yoke or lever are pivoted co-axially on a rocking arm, the over-centre spring being connected to the reciprocating member and one end of the yoke, and the rocking arm co-operating with the other end of the yoke to limit the movement thereof. In the mechanism shown in Figs. 2, 3, and 6, ratchet-wheels 64, 79 on the shafts 23 of the spools 16, 33 co-operate with pins 88, 89 on a reciprocating arm 50 mounted on a shaft 51 carried by an arm 41 which is rocked at each operation of the machine. A yoke 45 mounted on the shaft 51 carries shafts 57, 59 provided with blocks 58, 60 receiving sliding rods 75, 82 which are connected to bails 65, 80 mounted on the shafts 23. The rods 75, 82 carry sliding sleeves 77, 84 abutting on springs 78, 87. An over-centre spring 63 connects the shaft 57 and a pin 62 on a depending part of arm 50. The shaft 59 passes through slots 56, 55 in the arms 41, 50, the slot 56 limiting movement of the yoke. Each of the bails 65, 80 is provided with a pawl 73, and a spring-urged yoke 69 carrying a roller 70, the pawl co-operating with a ratchet-disc 25 on the associated shaft 23, and the roller engaging the coiled ribbon on the spool. When the ribbon is being wound off the spool 16, the pin 89 co-operates with the ratchet-wheel 79, and the roller 77 associated with the spool 16 rises and eventually permits its pawl 73 to engage the ratchet-disc 25. Thereafter the bail 65 turns with the spool and retracts the rod 75 until the sleeve 77 abuts on the block 58 and throws over the yoke 45, the spring 63 completing the movement and also rocking the arm 50 to bring the pin 88 into engagement with the ratchet-wheel 64 and thereby reverse the feed. When the spool 33 is empty the bail 80 turns with the spool and causes the rod 82 to throw over the yoke and again reverse the feed. Specification 354,870 is referred to. Spools, mounting; brakes.-The spools 16, 23, Fig. 2, are each mounted on shafts 8, 23, Fig. 3, supported by bearings 4, 6, 29 and having pins 21, 30 engaging slots in the spool hubs. The shaft 8 has a hand-wheel 9 for feeding the ribbon. A brake-disc 15 mounted on the shaft 8 is held in contact with a bushing 5 in the bearing 4 by means of a spring 12 which abuts on a shoulder 13 on the shaft.
