Abstract: 365,324. Concrete piles. WATT, E. DE F., La Grange, Illinois, U.S.A. Jan. 17, 1931, No. 1605. [Class 68 (ii).] A shell in which a concrete pile is formed in situ is made in sections arranged end to end, but spaced apart and connected by sleeves so that the sections may move relatively during the driving operation. Fig. 1 shows a collapsable tapered driving core 10 encased by concrete shell sections 12, 14, 16, which are dimensioned so as to fit the core snugly before making end contact with each other, so that between the ends of the sections are left gaps 18, 20 which are then covered by plain or corrugated sleeves 22, 24. During the driving operation, these gaps close up by varying amounts. Fig. 6 shows a driving core 10 the lower end of which fits the driving shoe 28; this is made by placing thin metal shells 30, 32 in a mould, and pouring concrete between them. The shell of the pile is built up of sections each consisting of a thin metal casing 34, a concrete body 36, and rings or coils of wire 38 partly embedded in the concrete ; in driving the core contacts with the wires 38. In a modification, the wire 38 is wholly embedded in the concrete shell 36. After withdrawing the driving core the shells are filled with concrete.

Title: Linespacing mechanism for accounting machines
IPC: B41J11/36
Filed: 1956-01-23
Abstract: 788,088. Typewriters. NATIONAL CASH REGISTER CO. Jan. 23, 1956 [March 1, 1955], No. 2129/56. Class 100(4) For printing on books having an area of binding parallel to the lines of printing, feelers are provided to cause a three-line feed at predetermined points so as to avoid printing on the bound region. A pass book is placed on a table 30, Fig. 1, under a shield 31 and is fed into its initial printing position by rollers 32 under the control of cam 70 rotated once at each operation of the machine. Initially the cam 70 by a stud 67 on the follower acts on a pitman 61, levers 59, 58, slide 56, and a pinion 54 to move a pawl 50 to actuate a ratchet 42 which through gearing moves the feed rollers 32 until the book is one line short of a printing position. A low 73 then allows a return of the slide 56 under the action of a spring 74 until the arm 51 of the pawl 50 is arrested by a stud 80 contacting a stop arm 81, Fig. 10, so that when the cam again operates, as the low 73 passes, the pawl feeds back the book one line space. A retaining pawl 88 prevents backward movements of the ratchet 42. After printing, the book may be fed a single line space as above described for another entry or, at a predetermined position, it may be caused to move three line spaces by the control of feelers 116, 117, Fig. 1, on a stop arm 115. When the feeler 116 is allowed to rise while the feeler 117 is kept depressed, a coupling pawl 135, Fig. 1, can engage a shoulder of an arm on a shaft 130 when acted on by a cam mechanism so that the shaft 130 mounting the arm 115 is rocked to a position where the stud 118, Fig. 10, will prevent the stop lever 81 from engaging the stud 80 but allow it to engage a shoulder 119 so that the pawl 50 moves back far enough to cause a three-line space feed when it is next rocked. When both feelers 116, 117 are either raised or lowered together the coupling pawl 135 is prevented from moving to engage the shoulder. The mechanism for three-line spaces is disabled by certain totalling keys by a coupling which locks the feelers in their lowest position. An ejection pawl 91 coupled with a retaining pawl 88 ejects the book by its action on a ratchet 43 after printing and is controlled by the keyboard and a cam mechanism. As described the device is incorporated in a type wheel printing machine.
