摘要： In grinding non-uniform workpieces rotating about a longitudinal axis an endless abrasive belt passes over a contact roll in tangent contact. The rotating workpiece is pressed against the belt at the tangent point and the belt is passed around the workpiece on at least one side from the contact point. The amount of wrap is sufficient to heat the workpiece relatively uniform. Either plunge or traverse grinding may be used.

摘要： 1,218,827. Window balancing devices. D. J. DINSMORE CO. 14 March, 1968 [17 July, 1967], No. 12528/68. Heading E1J In a spring balancing assembly for a sliding window a double pulley block 24 forms a floating anchor for one end 22 of the extension-compression spring 21 the other end 20 of which is secured through strip 15 and end plug 12 to a sash, as by screws through holes 14, the block 24 comprising a frame in two similar parts 40, 41 each carrying a shaft 42, 43, which shafts when the parts are placed together and held by a frame 50, 51, 52, Fig. 5 are at equal acute angles with opposite sides of the frame and are thus oriented transversely with respect to each other and staggered vertically of the frame, the floating anchor being connected by cable 33 to a fixed anchor formed by a second pulley block 25 having a housing 53, 54, 55, 56, Fig. 4, in which a single shaft 32 is transversely disposed and carries two pulleys 30, 31, held in place by a wire axle hanger bracket 58 engaging in grooves 57 on the axle 32 and engaging with its hooked ends 59, 60 in notches 61 in the fixed anchor 25, the walls 54, 55 having scalloped edges to cooperate with the flanges of the pulleys 30, 31 in retaining cable 33 from becoming disengaged from the pulleys and the wall 56 being likewise cut away to allow the pulleys to be mounted on the shaft 32. Cable 33 at one end is secured to the frame 50 and passes downwardly and secured around the pulleys of both blocks 24, 25 and after passing through channel 62 and a bore in the shaft 32 is secured at its other end to a bolt member 35. The U-shaped channel 11 has depressions therein to eliminate lateral movement of the coil 21 but allows twist of the coil and rotation of the floating anchor 24.

摘要： A safety lock assembly for use with a garage door to prevent the latter from falling uncontrollably in the event the counterweight system supporting the garage door fails. The invention has a pivoted arm biased into a position blocking door movement. The counterweight system is attached to the pivoted arm to overcome the bias. In the event of a failure in the weight supporting members, the built-in bias will move the arm into its position where further significant movement of the door is prevented.

摘要： The invention is directed to a stop device for a lift type overhead door such as may be counterbalanced by springs and cables and having guide rollers operating in guide tracks at opposite sides of the door. The stop fixture is disposed one at each side of the door and includes a pivoted door stopping dog having an operating arm extending generally parallel to a door supporting cable. The dog is positioned at one side of a track flange directly opposed to a roller at the opposite side of such flange and the dog with its operating arm are tied to this roller in a fixed dimension relationship. The operating arm is connected to a door supporting cable so that if the cable breaks the arm is immediately actuated by a spring to swing the dog into engagement with the track flange, backed up by the opposed roller at the other side of the flange, to grip the flange therebetween and thus prevent the door from falling.

摘要： A first and second element are pivotally hinged together. The first element is separated into a first and second portion by an indented line extending laterally across the first element. The first portion has a tapered configuration for driving the first element into a wall and an alternate embodiment has an end positioned at a right angle to hook over a brick when the bracket is mounted to a brick wall. The first element includes a pair of ears upon which the second element is mounted. The ears form stop surfaces for limiting the inward travel of the first element into the wall. The second element has a plurality of slidably mounted fastening nuts which are positioned between the second element and the wall. The bottom end of the second element extends inwardly towards the wall and cooperatively with the stop surfaces spaces the second element from the wall preventing the fastening nuts from contacting the wall.
