Title: Improvements in or relating to sound studios and acoustic devices therefor
IPC: E04B1/84
Filed: 1931-05-02
Abstract: 373,380. Devices for modifying acoustic properties of studios. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Eyring, C. F. ; 35, 163rd Street, Flushing, New York, Hanson, R. L.; 110, Beekman Terrace, Summit, and MacNair, W. A. ; 376, Prospect Street, East Orange, both in New Jersey, both in U.S.A.) May 2, 1931, No. 12996. Convention date, May 6, 1930. [Class 13.] Relates to the control of the reverberation time or rate of decay of sound waves in sound studios and the like, and more particularly to the scattering of sound waves of high frequencies, i.e. of 600 cycles per second and over. According to the invention, the high frequency sound waves are scattered by a diffusing device comprising a plurality of angularly disposed reflecting surfaces. These surfaces are of such dimensions that they reflect and do not deflect sound waves of 300 cycles per second and less. As applied to a sound studio 1, Fig. 2, a number of diffusers 23 are mounted upon or formed integral with each wall and are adapted to scatter the high frequency sound waves emanating from a -source 26 and to deflect them towards sound-absorbing material 21, 22, arranged upon the floor and ceiling respectively. By this means the high frequency sound waves are damped while the sounds of low frequency, which are not deflected by the diffusers, persist. In modifications, the diffusers and absorbing areas are arranged on adjacent. walls (including the ceiling and floor), the diffusers on opposite walls being disposed relatively in staggered formation so as to intercept any stray vibrations which might otherwise be set up between the reflecting surfaces between them. When formed as separate units, each diffuser comprises a number of angularly dispose slats 8, 9, Figs. 3 and 4, arranged between side members 4, 6 and between upper and lower frame members 5, 7. The troughs between the slats 8, 9 are divided into sections by vertical reinforcing members 10, 11. The reflecting surfaces may be of wood or of any metallic or non-metallic material and may be covered with a sound-absorbing material such as canton flannel. In one specific example, the reflecting surfaces are four feet long, have a slant height of one foot, and are arranged at an angle of 120‹ to one another.

Title: Improvements in or relating to honing devices
IPC: B24B33/10
Filed: 1938-05-03
Abstract: 512,734. Grinding cylinders. STEVENS, A. H. (Micromatic Hone Corporation). May 3, 1938, No. 13176. [Class 60] A device for grinding or honing cylinders comprises a honing tool 50 having an abrading element movable between an abrading and a retracted position, mechanism for advancing the tool from a starting position to a working range and then reciprocating the tool through the working range, an element 60 carried by the tool for moving the abrading element into abrading and retracted positions, and an operating member or cam 62 controllable by a mechanism adapted during reciprocation of the tool within its working range to move the member 62 so as to cause retraction of the abrading element. As shown, the tool 50 is provided with a grinding head 56 adapted to be rotated and reciprocated within a workpiece 58. The expansion and retraction of grindirig stones in the head 56 is controlled by the tripping finger 60 in co-operation with the member 62 carried by a boss 64 sliding on a standard 66 and operated by means of a sliding collar 80 connected by a link 84 and a bell-crank lever 88 to the rod 98 of a piston in a fluid-pressure cylinder 100. Fluid-pressure pipes 102, 104 lead from a valve 110 to the ends of the cylinder 100. In the downward movement of the tool 50, the finger 60 depresses the member 62 against a spring 68 until the boss 64 encounters a collar 70, whereupon the finger 60 is operated to expand the grinding stones and release the member 62, which is returned by the spring 68 to initial position. The tool then reciprocates within the workpiece and at each downward movement actuates a lever 118 to turn the valve 110 step by step by means of a ratchet 114 and pawl 116, until the valve reverses the fluid connections. The fluidpressure piston then moves the collar 80, and the member 62 downwards, so that the finger 60 releases the grinding stones and these are retracted. The upper end of the tool 50 then engages a plate 124 on a vertical rod 122 connected to an arm 112 on the valve 110, which is turned to reverse the fluid connections and to effect the return of the collar 80 to its initial position. For controlling a number of honing tools, a plate carrying a number of cams 62 is supported at each end by a member 64 sliding on a standard 66 and connected to a cylinder similar to 100, which is connected to the valve 110 by pipes 106, 108.

Title: Improvements in and relating to automatic machine tools
IPC: B23B9/12
Filed: 1919-05-26
Abstract: 154,947. Marks, E. C. R., (Bullard Machine Tool Co.). May 26, 1919. Lathes.-In an automatic indexing work-turret machine tool, adapted to perform turning, drilling, milling or like operations, the feed mechanism for each tool-holder includes a cam 158 which causes motion of the tool holder 167 towards and across the corresponding work table in the turret. The downward motion is obtained by means of a roller 159 carried at the upper end of a rod 129 which terminates at its lower end in a rack 161, and the descent of the tool holder is by a stop, the continued movement of the rod 129 slides the tool-holder 167 crossways by means of rack-and-pinion gearing 166, 163. The cam 158 is mounted on a shaft 156 and carries a worm wheel 155 driven by a worm on a shaft 145 which carries two clutch members 144, 153, the former driven at the higher speed by helical gearing 142, 143, a vertical shaft 140 and a wheel 141 gearing with a central toothed wheel 60 which drives all the feed mechanisms. The slow speed clutch member 153 is driven through toothed wheels 151, 152, worm gearing 148, 149, and change wheels 146, 147 from the shaft 140. The higher speed clutch is first put into action by means of a series of lugs 167, one for each feed mechanism, mounted on a central controlling drum 66, which rotates intermittently. Each lug 67 engages an arm 68 and thereby moves a sliding rod 187 which carries a pointed tappet 188 engaging a spring plunger 189 on the lower end of the clutch-operating lever 190. The change to the slower speed (for the operative part of the stroke of the tool carrier) is effected by adjustable trip pins 195 carried by a disk on the cam shaft 156, which pins engage a hooked lever 196 and thereby move the rod 187 over to disengage the higher speed clutch and put in the lower. This operation can also be performed by hand whenever desired by means of a handle 200. The tool holder 167 is stopped at the top of its travel after one complete rotation of the worm wheel 155 by means of a dog tooth 179 which pushes a stop 180 into a position to hold the clutch members in the neutral position: this stop being spring mounted is adapted to yield when the feed mechanism is restarted. A. second controlling drum 69 is provided to control the indexing and rotation of the work tables 91, the central shaft 51 being stopped after each complete rotation and re-started again when all the feed mechanisms have returned to their highest positions. This indexing action is more fully described in Specification 153,863. The main drive is by an electro motor or otherwise to a shaft 36, which is clutched by a. hand lever 52 at starting to a pinion 59 driving the wheel 60, and thereafter is automatically connected and disconnected bv cams 65 on the drum 66.
