Title: Feeding mechanism for sewing machines
IPC: D05B27/14
Filed: 1938-11-07
Abstract: 505,072. Sewing machines. FAIRWEATHER, W. C. (Singer-Manufacturing Co.) Nov. 7, 1938, No. 32169. [Class 112] Feed.-In a sewing-machine having a feeddog 9 and puller feed-rolls 33, 35, the two feeds being separately adjustable, means are also provided for varying the two feeds simultaneously and equally without stopping the machine so that shorter stitches may be formed at certain parts of a seam. In the machine shown, the feed-dog 9 is mounted on a feed-bar 10 which derives its lifting movement from an eccentric 60 on the main lower shaft of the machine and its feeding movement from an arm 12 on a rockshaft 13 ; the lower feed-roll 33 is mounted on an actuating shaft 23, the upper roll 35 being freely mounted in a spring- pressed carrier 38 provided with a lifting lever 41 with a holding latch. The shaft 13 is driven from the shaft 8 by an adjustable eccentric 20, Fig. 4, actuating a pitman 19 with a pin 17 carrying a slide block which engages an arcuate slotted arm 14 on the shaft 13 ; the pin 17 has an eccentric portion, so that by rotary adjustment of it. the feed-dog 9 can be centred in its slot in the throat-plate. The shaft 23 is driven from the shaft 8 by a second adjustable eccentric 46, Fig. 5, synchronized with the eccentric 20, actuating a pitman 46 with a pin 56 engaging an arcuate slotted arm 47 fixed to the driving member of a ratchet clutch which drives the shaft 23 intermittently in one direction when the arm 47 is oscillated; backward movement of the shaft 23 is prevented by a second ratchet clutch having one member held stationary by a forked arm 54 engaging a stop block 55 on the machine frame. The mechanism for simultaneous variation of the two feeds comprises a forked arm 21, Fig. 4, freely mounted on the shaft 23 and embracing the pin 17, an arm 26 clamped on the hub of the arm 21, and a lever 28 pivoted to the frame at 29 and connected to the arm 26 by a link 27 ; the arm 28 has a portion 28<1> of channel section embracing the end of the pitman 46, Fig. 5, and slotted to receive the pin 56. Movement of the lever 28 by means of a treadle and chain 32 thus shifts the pins 17, 56 along the arms 14, 47 to vary simultaneously the amplitude of the feeding movement of the shafts 13, 23, the mechanism being so proportioned that equal variations are produced in the two feeds ; the mechanism is biassed to the long-stitch position by a spring. 30 attached to the arm 21.

Abstract: 1,241,244. Printing. MARK-O-PRINT G.m.b.H. 26 June, 1969, No. 32258/69. Heading B6C.  An apparatus for printing on objects e.g. paper bags containing flour, moved by conveyer means along a plate 22 having an opening 21 at the printing position, comprises a printing stamp 2 mounted in a guide 4 which is movable to a limited extent towards the opening 21 for impression under control of the objects, the stamp 2 being freely slidable in the guide 4 so that when the impression movement of the guide 4 is stopped, the stamp 2 continues to move by its momentum to pass through the opening 21 and mark the object. The guide 4 is attached to two arms 16, 17 pivoted to a base-plate 15 at their remote ends, the arm 17 being also pivoted to the armature of an electromagnet 19 which, when energized by the approach of an object, moves the arms 16, 17, the guide 4 and the stamp 2 upwardly towards the opening 21. A rubber buffer 11 arrests the arms 16, 17 and therefore the guide 4, but the stamp 2 is free to continue its movement to effect an impression.  Inking.-In the inoperative position, an inking roller 1 rests on the stamp 2, the roller 1 being carried by arms 8 pivoted on a spindle 6 and held in such position by springs 20. Plates 25 attached to the guide 4 engage rollers 24 situated near the ends of the inking-roller spindle so that as the guide 4 moves upwardly, the roller 1 is first caused to roll over the stamp 2 and is then moved out of the way of the stamp. The arms 8 are drawn towards one another by a spring 5 and the spindle of the ink roller and the spindle 6 are plain shafts, this arrangement facilitating assembly of the inking device.

Filed: 1927-12-07
Abstract: 313,100. Ha.zlehurst, H. E., and Margetson, O. Dec. 7, 1927. Pulverulent-fuel burners. - The mixture of powdered fuel and its carrying air is divided prior to its admission into the combustion chamber into two streams, one stream preferably containing one and a quarter times and the other preferably containing not more than one third the air necessary for the combustion of the contained fuel so that the rate of flame propagation in both streams is relatively low; the two streams are discharged into the combustion chamber in such a manner as to converge on each other and form a mixture in which the rate of flame propagation is relatively high. The division may be effected by a cyclone separator before the mixture reaches the burner or may be effected in the burner itself. Fig. 1 shows one form of burner in which the mixture of fuel and air is supplied to a chamber a through a tangential inlet b. The heavier fuel particles travel round the circumference of the chamber a and are discharged through an annular outlet d with sufficient air to form a stream of rich mixture while a weak mixture of the lighter fuel particles and air passes through an outlet e into an annular chamber f surrounding the chamber a and issuing through an annular outlet g converges on to the stream of rich mixture. The inner edge of the outlet d is formed by an adjustable tubular member h through which secondary air or gaseous fuel may be supplied, and in which an oil burner may be arranged. Additional air may also be supplied through adjustable ports k. Fig. 3 shows another form of burner in which the fuel mixture is supplied through a curved pipe l and the lighter fuel particles are diverted by a hinged flap m into an annular chamber p having a converging discharge, passage r while the heavier fuel particles are discharged through a central passage g. The passages r, g are provided with inclined ribs t, u which cause the weak and rich streams of mixture to rotate in opposite directions. Burners may also be constructed with flat elongated discharge passages.
