Title: Improvements in tube welding machine
IPC: B21C37/08
Filed: 1923-10-08
Abstract: 224,060. Schaefer, A. C. Oct. 8, 1923. Welding.-A tube-welding machine comprises a rotatable mandrel 22 and a welding-roll 34, the latter being mounted on a shaft 27 which is supported in a bearing on a frame comprising a bracket 30, upright posts 31 and a bracket 32, the frame being supported, preferably resiliently, on a bedplate 10. The bracket 32 is connected to the stem 37 of a piston 36 fitting in a cylinder 35 into which compressed air from a feed pipe 38 may be supplied through a valve 39. The valve may be operated by means comprising a crankarm 40, an arm 41, an adjustable collar 48 on a rod 43 and a treadle 45. The upper end of the rod 43 is provided with a yoke 51 which is formed with vertical slots engaging pins 52 on the bed-plate 10. The yoke carries pivoted arms 54 with rollers 56 which may be adjusted relatively to each other by means of a conical nut 57 screwed on the rod 43 and engaging the inner ends of the arms 54. The roll 34 is driven through flexible shafting 26, and the mandrel 22 is detachably secured to the shaft 13. When the treadle 45 is depressed the valve 39 is opened and the piston 36 is depressed, bringing the roll 34 into contact with the tube sections 74, 75. The treadle is then further depressed, bring- ing the rolls 56 into contact with the welded tube to straighten it. The outer tube section is supported by a back rest comprising a hollow standard 61 supporting an adjustable post 62 on the upper end of which a yoke 65 is secured. The yoke carries a pair of pivoted arms 67 provided with rollers 69 and adjusted relatively to each other by means of a conical nut 72 which is screwed on the post 62 and bears against the inner ends of the arms 67. The tube 75 is supported on the rollers 69 and on balls 71 seated in the top of the yoke 65.

Filed: 1925-10-08
Abstract: 247,874. Croad, A. K., (Amsco Products, Inc.). Oct. 8, 1925. Condensers of the variable type comprise a rotor plate set carried by end plates, a pair of members connecting the end plates, a pair of supports for a stator plate set insulatably mounted between and arranged to bear in opposite directions on the end plates, characterized by the connecting members lying in a plane which intersects a plane embracing the supports for the stator plate set, whereby the connecting members in co-operation with the supports constitute the means for holding the condenser parts in assembled, balanced and fixed relation. The shaft 11 of the rotor R is journaled in bushings 12, 13 adjustably and threadedly received in end plates p, p' in and held in position by nuts 14, 15, the adjustment being effected by gripping- heads 16, 17 on the bushings. The plates S of the stator are supported by posts 19, 20 arranged to bear in opposite directions on the plates p, p<1>, insulating members 21 - - 24 being provided and comprising each a short tubular member one end of which seats in an element 28 riveted in the end plate while the other end has an end cap 29 apertured to receive a stud 30 integral with the posts 19. 20. In this way the parts are interlocked and by eliminating securing elements the amount of dielectric is reduced and therefore the electrostatic field in the region of the supports. Further, by thus disposing the members 21 - - 24 the maximum supporting strength thereof is utilized as the supporting forces lie in the plane b, Fig. 2. To produce a balanced and stable structure with ease of assembly, only two connecting members 25, 26 are used for locking the plates p, p<1> and parts in assembled position, the plane a in which they are located being at an angle to that b of the supports. To balance the thrusts exerted by the shaft 11 on the end plates, a third connecting member 31 is secured to the latter in the plane c, while the plate p<1> has stops 32, 33 which engage in turn with a part 34 on the shaft to limit the travel of the latter to 180‹. The plates may be contoured as desired, and as shown yield a straight line frequency calibration curve. In Fig. 3 is shown an application to a multiple unit condenser therein the stator plate sets are mutually insulated bv members 36, 37 having end caps 38 similar to those 29.

[Class 60] [See also Group XXII] In apparatus for measuring and machining vehicle frames particularly railway bogie frames 3, two or more machine tools such as milling machines 2 or grinding machines adjustably mounted on a common bed 1 are each provided with measuring and machining devices arranged as a single unit adapted for treating the axle bush guides of the frame 3. A separate milling- machine 4 for milling the swing bolster space may be arranged between the machines 2, which are adjusted so that their centre distance a corresponds to the wheelbase of the bogie to be machined, abutment bolts 22 being inserted in spaced holes in the machine bed for this purpose. Each milling-machine comprises a pair of headstocks 5 on a vertically adjustable transverse bed 6, both headstocks being driven from gearing 6a. The headstocks carry spindleheads 7 which may be oscillated around horizontal axes x, Fig. 4. The headstocks are provided with holders 9 adapted to receive measuring instruments 10 which are located at the correct centre distance of the bogie axles by means of an index bolt 8 which locks the spindle head 7 in its vertical position. The oscillations of the spindle head to determine the half distance b between the guide cheeks 15 are effected by gearing 11 and are limited by abutments 13 which are set by means of scales 14 and which coact with the gauge bolt 12 which is of smaller diameter than the measured diameter of the cutter 16 in the ratio e : d. In operation the spindle head is swung to the left, Fig. 4, and the head moved upwards to mill the left-hand cheek, whereupon the head is swung over to the right and the right-hand cheek milled in a downward direction. The bogie frame is secured in the machine by clamping brackets 17<11> adjustably mounted on a bed 17<1> and operated by clamping gear 18. The stationary milling machine 4 for milling the swing bolster space has two milling heads 19 shiftable transversely on a bed 20 which is fed vertically for the milling operation. Supports are provided for mounting measuring instruments for checking the dimensions of this part of the work after each machining operation. Each milling head 19 carries also a drilling spindle so that holes may be drilled in the swing bolster guide plates.
