Granted: 1905-01-12
Abstract: 6703. Peck, C., and Peck, W. W. March 19. Loom change-box motions.- Relates to change-box motions of the kind described in Specifications No. 6209, A.D. 1888, No. 3544, A.D. 1889, and Nos. 8727 and 26,130, A.D. 1902, and more particularly to that part of the mechanism which controls the relative positions of the discs f, the rotation of which effects the actual shifting of the shuttle boxes. As described in Specification No. 8727, A.D. 1902, sliding bolts 1, 2 are used to put the rising and falling racks v into gear with their pinions, and to lock the discs f by engagement with the rims f<1>, but instead of the bolts being operated upon directly by the cards on the card barrel 11, they are operated by projections p<1>, r', respectively, on rocking shafts or sleeves p, r. Each shaft or sleeve p, r is so mounted that it may be slid longitudinally by means of inclined planes or cam-pieces g', g', g<3>, g<4> on the discs f acting on projections p<4>, r<5> on the shafts or sleeves p, r respectively, and when any one of the four shuttle boxes is in its operative position, the shafts or sleeves p, r are in a definite position ; thus, Fig. 7 shows the positions of the shafts or sleeves when the top shuttle box is in its operative position. The shafts or sleeves have projections p', p<3>, r<2>, r<3>, r<4>, which are moved by needles n<1>, n', n<3>, n<4>, according to the position of the shafts or sleeves, when the needles are pushed against the action of springs 1<b> by the cards on the card barrel. When a projection is moved, its shaft or sleeve p or r is partially turned, and the corresponding bolt 1 or 2 is moved against the action of a spring 1<c> by the projection p<1> or r<1>. The projections p<2>, p<3>, r<2>, r<3>, r<4> are so arranged that, when the shafts or sleeves p, r are in any position, the first, second, third, or fourth shuttle box is brought into operation according as the needle n<1>, n', n<3>, or n<4> is pressed by a blank part of a card. If desired, a fifth needle may be provided to act as a reveraing-needle to reverse the direction of rotation of the card barrel when required, in the manner described in Specification No. 19,829, A.D. 1903. In the Provisional Specification, it is stated that an independent reversing-motion may be used.

Title: Improvements in Slide Rules
Inventor: SMITH RUDOLPH CHARLES
Filed: 1904-08-11
Granted: 1904-09-22
Abstract: 17,499. Smith, R. C. Sept. 12, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Slide rules.-A logarithmic slide rule has a small rule attached for determining decimal places of results. The main slide 1 moves on the stock 4 below a flexible transparent covering-plate 2 kept in place by the rivets 3, an ordinary cursor 6 being provided. At the right end of the rule is a complete small rule consisting of fixed scales 7, a movable scale 8, and a cursor 5 having three reading-edges ; the movable scale and one limb of the fixed scale are divided uniformly according to the powers of 10, while the other limb is divided according to the nearest corresponding square numbers to agree with the upper fixed limb of the main stock, which is a scale of square roots. With this auxiliary slide rule, the operations of the main rule are imitated, the numbers set and read off being in each case the highest power of 10 which will give a quotient not less than unity when divided into the corresponding main scale quantity. In setting on the auxiliary rule, the figures on the left and right halves of the main rule are thus distinguished. The figures on the left half are framed off by a red band 12, 10 on the fixed scales and a similar band 11, 13 on the slide. The right half is in white as usual. The cursor 5 is coloured red between the reading-edge 17 and the opening 16, and the colours of the factors in any calculation determine on which edge of the cursor 5 readings are to be taken.
