As shown, the pieces 1, 2, 3 .... of a map may be shaped to represent counties or parts of counties, and may be formed as mouldings or pressings of thermoplastic or thermosetting material so that depressions 4, 5 representing lakes and the like and perforations 8. slots and the like may be easily formed therein. If desired the pieces may be formed of plywood or card and the holes and depressions confined to a certain depth instead of formed right through. Similarly surrounding water may be represented by the removal of the upper surface as at 12 or by pieces of less thickness than the land pieces. Towns may be represented by blocks or posts 6 of circular, rectangular or other cross-section and having pins 7 for insertion into the perforations 8 at the appropriate positions. The blocks may be impressed or printed with the names of the places they represent, or they may be replaced by similar flags or pennons. Rivers may be indicated by slots or channels into which conveniently formed strips of sheet metal may be fitted. The strips may be of such a height that a part projects above the level of the pieces for ease in taking apart, and may bear the appropriate name thereon. Alternatively they may be represented by lengths of cord pressed into the slots. Additional pieces 10 represent hills. Railways and lines of communication may be represented in a manner like that of the rivers. The puzzle is applicable to designs other than maps, for example, flowers and animals upon suitable surroundings as background. The pieces may be coloured distinctively.

Title: Improvements in or relating to lathes
Inventor: KOLLER HANS
IPC: B23B29/24
Filed: 1953-09-10
Abstract: 748,620. Combined lathes and boring machines; lathe details. PFEIFER, H., and PFEIFER, E. Sept. 10, 1953, No. 25122/53. Class 83 (3). A hollow cutter-head 1, Figs. 1 and 4, is fixed to a lathe-spindle A for turning bar or tube-stock F clamped in a block I fixed to the saddle E fed towards the head against an adjustable stop Q. The head contains tools 11, 15 which rough and finish turn, respectively, the outer diameter, and a boring tool 5 which turns the inner diameter. Tools 11, 15 are adjustable radially and axially of the head and tool 5 is adjustable radially only. After abutting the stop Q, the saddle is returned, e.g. by a spring, to abut a stop P and the work is parted-off by a tool 13. This tool is clamped to an arm 6 attached to one end of a rod 7 extending through a bore in the head and having fixed at its other end a lever 27. A peg 28, Fig. 3, on the lever engages a cam-slot 37 in a ring 3 capable of rotating relatively to the head 1. A similar lever 26 mounted on rod 30 and having peg 29 in cam slot 38 is diametrically opposed to lever 27. To move the parting tool, a lever C is turned to cause a brake H to contact a groove 3a of the ring 3, thus causing it to turn relatively to head 1, with the result that the pegs 28, 29 move towards the outer ends O of the slots and turn the levers 26, 27. Thus tool 13 moves towards the centre of head 1 to part the work. An end facing tool on an arm may be fixed to rod 30 to be operated simultaneously with tool 13. On release of lever C, springs 33, 34 restore the parts to their initial position. Either arm may carry a thread-cutting tool applied to the work by lever C while a feed of appropriate pitch is performed by the saddle, the depth of thread being governed by slot 37 or 38.

Title: Multiple pattern sewing machine
IPC: D05B19/00
Filed: 1974-06-13
Abstract: 1474197 Automatic control of sewing machines SINGER CO 13 June 1974 [5 July 1973] 26197/74 Heading G3N A multiple pattern sewing machine includes a memory containing each pattern as a plurality of sequentially grouped digital code words, each word corresponding to a stitch in the pattern and each group having a unique starting address, pattern solution means including a counter operable to apply an addressing signal to the memory and subsequently to re-address the memory each time a machine derived pulse is received whereby a sequence of code words is read out corresponding to the selected pattern to operate the stitch forming apparatus of the machine to produce that pattern. In the arrangement shown the output from the read only memory 92 consists of a 10 bit word of which the first five bits control the needle bight actuators 30 and the second five bits control the material feed actuators 43. The memory is addressed by a counter 93 which is clocked by movement of the needle driving armshaft to sequentially advance the read-out from the memory. The bight and feed movements for each stitch of a pattern are stored in the memory at a sequence of addresses starting at a specific address and finishing with a resetting word, 11111 in the described embodiment, which acts through AND gate 135 and OR gate 137 to reset the address counter. The pattern is selected by manually operated contacts 50-53 which, by the action of NAND gates 55, 57, 60 puts a selected energization on lines 70, 71 to be maintained on lines 72, 73 by latch 69 until a different pattern contact is operated. The energization on lines 72, 73 is translated in address memory 91 into an 8 bit binary code which causes the address counter to output a 9 bit binary code word corresponding to the address of the starting stitch in the selected pattern. The address counter then steps on in synchronism with the needle operation until the pattern is completed and the reset signal appears. Since the lines 72, 73 are still energized the same code will exist at the output of address memory 91 and so the memory 92 will be addressed to the start of the same pattern which will repeat. The resetting arrangement may be modified by including a comparator to determine the pattern end code.
