Title: Improvements in or relating to methods of and apparatus for severing glass or the like
IPC: C03B33/09
Filed: 1927-11-25
Abstract: 281,324. Gregg, H. L., (Assignee of Campbell, F. N., and Myatt, J.). Nov. 27, 1926, [Convention date]. Cutting glass.-A method of cutting sheet glass along a desired line of cleavage consists in heating the glass along the line and also heating, to a lesser degree, the areas of glass adjacent to the line. Apparatus for carrying out the method comprises an electrically heated wire 41, extending below the desired line of cleavage in association with heating plates 48, 49, and a movable supporting frame arranged to raise or lower the heating plates and the wire into or out of proximity to the glass. The sheet of glass 21, is supported on a table 20, Fig. 2, which is provided with a gap 40. Pairs of rollers 24, mounted on yokes 27, project through slots in the table and facilitate the movement of the glass sheet on to the table, the rollers being driven by power if desired. The yokes 27 are secured to vertically slidable members 31 which are connected to the ends of pivoted levers 34, the other ends of the levers being connected to vertically sliding members 81 on which the heated wire 41 is mounted. A treadle 88 enables the rollers 24, and the wire 41, to be raised or lowered. When a glass sheet is placed in the cutting-position, the rollers are lowered and allow the sheet to rest on antifriction supports, such as balls 39, mounted on the table top. The wire 41 is mounted below the gap 40 and is carried by a strip 42 of insulating material. On each side of the strip are electrically heated plates 48, 49 which are adjustable vertically and horizontally in relation to the wire and to the members 81 on which they are mounted. These plates consist of strips of insulating material with holes through which resistance wires are laced. The wire 41 is stretched between a terminal 50, Fig. 4 and a spring 52, both secured to the insulating - strip 42. The wire is in contact with the glass only at one point, preferably at its end, and for this purpose is formed with an enlargement 60. For the remainder of its length, it is kept a little distance from the glass and lies directly below the desired line of cleavage. A cutting wheel 91, located at one end of the table, may be used to nick the glass sheet at the edge to initiate a crack. In operation, the wire 41 and the plates 48, 49 are first raised to the proper temperature, the parts of the machine being in the position shown in Fig. 2. A sheet of glass is run on to the table by means of the rollers 24 and when adjusted in position, is nicked by means of the cutting wheel 91. The treadle is then depressed so as to lower the sheet on to the table and to raise the heated wire and plates into position close to the underside of the sheet. A modified form of machine for use in cracking a strip from the edge of a sheet, has only one heating plate which is arranged on the side of the wire towards the body of the sheet.

Clutches and speed-varying mechanism.-An hydraulic speed gear comprises a rotor 1, Fig. 2, fixed to the driving shaft 4 and having larger and smaller compartments 6, 7 in which are disposed drums 9, 12 provided with radial sliding vanes 8 13, the drum 9 being fixed to the driven shaft 10, and the drum 12 being normally stationary. The compartments are connected by helical passages 15, 16, Fig. 3. If the connection between the passage 15 and the compartment 6 is closed, and connection is established between the passages 15, 16, a direct drive is obtained; if desired the drum 12 mav be allowed to rotate at this time in order that there shall be no circulation of liquid in the compartment 7. In the modified form shown in Fig. 7, provision is made for obtaining a direct drive, free running, a number of speed ratios, and a reverse drive. In this form, a rotor composed of members 24 - - 28 is secured in a casing carried by the driving shaft 21, the space between the members and the casing serving as a suction chamber 30. Drums 31, 32 secured to the driven shaft 34 are provided with hollow vanes 33 and the coacting pressure passages 40, 41, lead to a chamber 62 and valve 43. Members 47, 48, 49 with radial vanes 50, 51, 52 are keyed to a sleeve 53 which is normally held stationary by a brake band and drum 59, the coacting pressure passages 44, 45, 46 leading to the valve 43 and chamber 62. Both chambers 30, 62 are provided with closures accessible from the outside through which liquid can be introduced and air removed. The valve 43 is operated from a sliding sleeve 66 through means comprising gear wheels 67, 70. Free running is obtained by so placing the valve 43 that all the pump elements are short-circuited, and the direct drive by operating the valve, to interrupt the communication between the pump elements 31, 32 and the pump elements 47, 48, 49. At both these times, the sleeve 53 is preferably released so as to be capable of rotation. Different speed ratios are obtained by placing the pump elements 31, 32 into communication with the pump elements 48, 49 or both 48 and 49. Reverse drive is obtained by connecting the elements 31, 32 with all the elements 47, 48, 49. The vanes 33, 50, 51, 52 abut against lining rings 81 provided with recesses 82, 83, Fig. 17, communicating through recesses 85 with the pressure and suction passages of the apparatus, and grooves 84 through which the liquid obtains access to the interiors of the hollow vanes. In a modified form, the side recesses are omitted, and the liquid is admitted to the chambers through holes. 85, Fig. 18, in the rings. In order to obtain balance, the vanes 91 - - 94, Fig. 20, carried by the driven rotor are disposed as shown, and a similar arrangement may be adopted for the fixed system on the sleeve 53.
