Cloth measuring machines
272,392. Vanderveld, A. Dec. 7, 1926. Measuring.-A cloth measuring machine is provided with means, e.g. a metal plate 90, for covering the readings should the measuring operation be started with the cloth beyond its proper starting point and also with a bar 93 which prevents any attempt to introduce cloth between the measuring and pressor roller 9, 51 when the same are in contact. The invention is shown applied to a measuring and cost-computing machine as described in Specifications 194,891 and 241,265. When the lever 60 is depressed to lower the presser roller 51 through the cam and lever 66, 67, it raises the bar 93 by means of the pin and cam 92, 98<a> and lowers a frame 70 pivoted on a shaft 68 by means of the arm 91 and cam 69. An extension 72 of the frame is provided with a lip 73 and a pin 75 on which is pivoted an integral cam 77 and block 76 which dips into a recess in the table 43. One face of the block is the proper starting point for the cloth to be measured but if the cloth projects beyond this point the block 76 is swung about its pivot 75 and, either by means of the cam 77 or a spring wire 78, moves a two-legged lever 81 which through a pin 88 and shaft 86 moves the plate 90 over the readings. A lip 84 on the lever 81 has now passed beyond the lip 73 and if the cloth is not readjusted to allow the block 76 to return tn a vertical position, the lips 73, 84 would engage when the lever 60 was released to raise the presser roller 51 and the plate 90 would remain over the readings. On the release of the lever 60 the bar 93 falls, and its pivoted end 95 passes into a slot in the table 43, as shown in Fig. 3, if no cloth is present, it is knocked into a horizontal position clear of the cloth and held there by a spring 99 and projection 97 on the bar 93. When the bar 93 is next lifted, its end 95 contacts with a stop 101. and is again moved into a position in line with the bar 93 as shown in Fig. 3.
