143 Improvements in copying lathes GB768032 1932-03-15 GB379999A 1932-09-08
379,999. Lathes. WINKLE BRœDER, Altenstadt-on-Iller, Germany. March 15, 1932, No. 7680. Convention date, March 16, 1931. [Class 83 (iii).] In a copying-lathe for producing articles such as shoe-lasts, rifle-stocks, pipe-bowls, &c. in materials such as metal, wood, horn, &c. the tracer roller c and rotary cutters d are carried by levers k, l respectively and the stationary driving motors s for the cutters are arranged concentrically with the pivots m of the levers l. As applied to the production of shoe-lasts, right and left hand lasts b are made simultaneously from a pattern a, but one or more work-pieces may be produced simultaneously from one pattern and of the same size or larger or smaller. The pattern and blanks are clamped between spindles e, f on a slide h which is traversed axially during cutting by a screw i. The levers k, l are joined by links n and are influenced towards the work by a spring o, but may be held withdrawn by engaging a notch q on a handle p with a stop r. The motors s are fixed concentrically with the pivots m but independently thereof and drive the cutters through belts t. The feed screw i and lathe spindles are driven from a shaft (not shown) through gears I .. IV and the levers k, l may oscillate in an inverted position. The cutters d are of such a size that they can follow any recesses in the work.

355,798. Pattern grading machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester.-(United Shoe Machinery Corporation : 140, Federal Street, Boston, U.S.A.) May 28, 1930, No. 16409. [Class 97 (iii).] A pattern grading machine comprises four primary instrumentalities, viz., a model holder, a work holder, a model follower and a tool, suitably interconnected for relative motion to reproduce pantographically upon a work piece in the work holder a model in the model holder, and mechanism for imparting to one instrumentality a non-pantographic reproductional movement in a certain direction, adapted to be operated by relative movement of two of the instrumentalities while both are in ordinary pantographic grading motion. As shown in the Figure, there are five principal mechanisms. The first, which effects north and south movement between the tool 30 and the model follower 22 due to east and west movement between the primary instrumentalities, comprises the arc 78 which shifts the fulcrum 47 of the width grading lever 36 as operated by the bars 94, 100 and the carriage, that is by the length grading movement. Either of the bars 94, 100 may be pivoted to the bar 82 by movement of the handle 92 in opposite directions. In the central position of the handle 92 the arm 82 may be clamped to the bracket 50. The second has the same function as the first but operates when there is no length grading, and comprises the arc 78 driven by the length grading lever 32 through the. link 130, the lever 124, and the bars 94 and 100 as before. The third alters the width grading factor by effecting north and south movement between the tool and model follower due to north and south movement between the primary instrumentalities, and comprises the arc 78 as driven by the width grading lever 36 through the arm 160. The fourth mechanism alters the length grading factor by effecting east and west relative movement between the model follower 22 and the cutter 30 due to east and west movement between the primary instrumentalities, and comprises the pivoted arc 152, and the link 154 as driven by the length grading lever 32 through the link 156. The fifth mechanism effects east and west movement between the follower 22 and the cutter 30 due to north and south movement between the primary instrumentalities, and comprises the pivoted arc 144 and the link 146 as driven by the width grading lever 36 through the links 136, 138 and the crank arm 140. Specifications 335,200, [Class 79 (iii), Motor vehicles, Arrangement &c. of parts of], and 350,940 are referred to.

152 Improvements in or relating to the shaping of wood heels GB91628 1928-01-11 GB283525A 1929-04-11
283,525. United Shoe Machinery Corporation, (Assignees of Sawyer, W. N.). Jan. 12, 1927, [Convention date]. Planing; shaping by cutting.-In a machine for simultaneously grooving the breast and trimming the lip of a wooden heel by a cutter rotating about an axis oblique to the line of the heel seat surface, four heel blanks 80 are held each by a lever 52 against the central boss 72 of a rotating head 38 which is indexed through succesive right angles by a Geneva stop motion 28, 30. Each lever 52 is normally pulled open by a spring 56 and is closed by the action of a fixed cam plate 44 co-operating with a roller 68 on a lever 64 pivoted on the same pin 66 as the lever 52 and actuating that lever through a spring pin 62. Gauging stops 70 and exchangeable gauge plate 78 are provided, as well as a set of bosses 72 of different sizes. Each heel blank is held through two quarter revolutions of the head 38, during which time the blank is shaped by a motor-driven four-bladed cutter block 102, carrying two grooving knives 104<1> and lip-trimming knives 106. One finished blank is released and ejected after each quarter revolution of the head. Fig. 13 illustrates the nature of the surface 110 generated by the grooving knives 104<1>, and Fig. 15 shows the shaped blank, grooved and with the lip 105 trimmed. The cutter spindle 103 is driven by an electric motor 100 adjustable by sliding on a plate 94 which can be slid perpendicularly to the axis of the shaft 103 on a plate 88 which is itself pivotally adjustable about a stud 86 on a platform 84 inclined to the horizontal at 25‹. Diagrams are given showing the effect of the various adjustments.

283,393. Duchemin, G. W. May 5, 1927. Lathes.-A lathe for turning irregular forms such as boot lasts comprises a swinging frame 11 pivoted on bearings 12, 13 to the support 10 and provided with a sliding chucksupporting frame 20 carrying the chucks 19 for holding a number of work pieces 23 which are shaped from a single pattern 54 having independent movement controlled by length grading mechanism. The work and pattern are held up to the tools 48 and tracer wheel 77 respectively by means of a weight 18. The chucks are driven from an electric motor 41 mounted on the chuck support 20 and connected through belt gearing 40, shaft 39, worm gearing 38, reversing bevel gearing 32, 33, shaft 31, belt gearing 29, and spur gearing 26, 25, to the shafts 24 driving the work chucks. The shaft 31 has a screwed portion engaging a nut on the chuck frame 20 and the reversing gearing is arranged so that a slow working movement and a quick return are imparted to the chuck frame. The reversing-gear is actuated from a handle 35 which may be moved either by hand or automatically by means of stop collars 45 mounted on a rod 46 in the path of a rear extension 47 of the handle 35 which moves with the frame 20. The cutter spindles are driven from an electric motor 53 through belts 51. The pattern 54, preferably of metal, is mounted in a chuck 55 slidable on bars 56 and is rotated through a yoke-shaped extension of the gear 26 by means of a connector 57 sliding in a groove in the yoke. Longitudinal movement is imparted to the pattern through a rod 63 connected to a transverse bar 66 which receives its movement from a pair of links 68 pivoted to a fixed bar 76 and connected to the bar 66 by pins and blocks 69. The links are swung about the pivot 67 by means of pins secured to the chuck frame 20. The blocks 69 may be moved along the arm 66 by means of a screw 74 to vary the length of the work relative to the pattern, this adjustment being facilitated by a scale 81. Width grading is regulated by adjusting the pattern to and from the pivot of the frame 11 by means of the rod 27, an indicating scale 78 being provided on the rod 80 along which the tracer wheel 77 is corres. pondingly adjusted. In a modification, Fig. 10, the workpieces 23 and the pattern 54 are mounted on opposite sides of the pivotal axis of the frame 11 and the work and pattern are moved in opposite directions by means of a pivoted arm 82 connected by links 84, 85 to the work frame and pattern respectively. Length grading is effected by varying the points of connection of the links 84, 85 to the arm 82.
