Title: Sheet handling apparatus
IPC: C23C2/40
Filed: 1947-07-24
Abstract: 670,311. Endless belt conveyers. AETNA-STANDARD ENGINEERING CO. July 24, 1947. [March 10, 1947] No. 19924/47. Class 78 (i). Sheets held to the underside of a conveyer belt are conveyed in single file and thereafter released in groups which drop simultaneously onto a transverse conveyer positioned below, so that a plurality of columns of sheets are produced on the transverse conveyer. A stack of steel sheets 23, Fig. 2, is fed along a rollerway A onto an elevator 29 which raises the pile so as to maintain the top sheet at a fixed level in the feeder B, as described in Specification 670,384, [Group XVI]. The feeder B comprises a suction head 63, Fig. 8, which is moved between pull and chain line position by means of a reciprocating lever 64 pivoted at 65 to a sleeve slidably mounted on the conduit 62 leading to the head. A spring 63<SP>11</SP> between the head and the sleeve allows extra movement of lever 64 after the head touches the top sheet to be taken up by the sleeve sliding on the conduit. The sheets after being picked up by the head are received by nipping rollers and pass to the underside of a belt 79, Fig. 5, on which they are held by magnets 96, 961, 96<SP>11</SP> and 96<SP>111</SP>. The three latter magnets are permanently energized while the remainder are energized until the foremost sheet reaches a lever 103 which opens a switch 99 in the circuit. Switch 99 is mounted on a nut member which is traversible by means of a screwed shaft 101. By this means any desired number of sheets of any size extending between magnet 96<SP>111</SP> and lever 103 can be caused to drop simultaneously onto a transverse conveyer belt 98 having magnets 109 below the receiving point. Conveyer 98, Fig. 2, together with conveyer 79 is mounted on a carriage 21. Also mounted on the carriage is a doubles throw-out device E and a pickling machine F. The carriage is movable on rollers 22 to and from a coating unit G. The drive for conveyer 79 is taken from a motor on the feeder B through a removable coupling chain while the drive for conveyer 98 is taken from a motor on the coating unit which also drives the pickling machine and doubles throw-out device by means of chain couplings. This enables independent speed adjustments to be made to suit different sized sheets.

Abstract: 755,518. Drilling-machines. ALLEMANN, H. July 24, 1953 [March 30, 1953], No. 20643/53. Class 83 (3). A drilling-machine comprises a frame 1, Fig. 1, a tool-carrying spindle 4 rotatable in the frame, a work-table 11 to carry work 12 and movable in relation to the tool 22 along the drilling axis, the mounting of the spindle in the frame or the mounting of the work in the table being such that during a stage in the movement of the table from the inoperative to the drilling position, the spindle or work has radial play for aligning the work and tool, which, during subsequent movement and during drilling, are held in alignment. In one embodiment spindle 4 is connected by a square end 4<SP>1</SP> to a member 2 supported in the frame 1 and driven by means, not shown. The spindle is supported by a bush 6 having play in a part 8 and having radial pegs 7 engaging V-shaped slots 81 in the part. A plate 61, attached to or integral with the bush, has pegs 16 to engage locating-holes 121 in the work 12, which is mounted in a recess in the table 11. The thrust during drilling is taken by a nut 5 on spindle 4 engaging the end 21 of member 2, and a spring-loaded foot 13 presses the work into the recess. Should the drill break, the nut 5 drops and engages an adjustable contact 21 to complete an electric circuit, causing stoppage of the machine. If the pegs do not enter the holes 121 the bush 6 engages an adjustable contact 29, as the table is moved, to complete an electric circuit and stop the machine. In a modification, the pegs 38, Fig. 4, in the plate 39 engage holes in a member 34 which has a recess engaging the upper end of circular work 33, the member being urged by a spring 36 to position the work accurately, the bush 39<SP>1</SP> then being moved to align the pegs with the holes. In another embodiment, the spindle has no radial play and the work is located in a recess by a bridge-member containing a drilling bush and having a peg to engage a hole in the work and an inclined surface to engage an edge of the work. In a modification, pegs 55, Fig. 7, in a member 56 fixed to the frame engage holes in adjustablymounted work 51. Plate 52 serves to strip the work from the pegs after drilling.
