Abstract

451,086. Measuring-tapes. MATTSON, N. S. A., and DAHLQVIST, K. E., Kvitsleby, Sweden. Jan. 8, 1936, No. 621. Convention date, Jan. 10, 1935. [Class 106 (ii)] The drum or reel is mounted within a pair of retaining frames 2 at the upper end of which is rotatably mounted a handle 3 provided with a brake arrangement co-operating with the reel. One end of a flat spiral spring 24 is attached to the inside of the drum 1 at 26. The inner end is attached to the boss 18 of a wheel 17 rotatable on a bush 16 on a screw 15 journalled in the frame 2. The wheel 17 is an annular wheel and gears with a wheel 19 on a spindle 20 in the side of the drum. This wheel 19 gears with a wheel 22 which by means of a squared boss 23 is connected to turn with arms 11, 12, 13. The arm 11 holds the end of the tape when wound up, the arms 12 and 13 limiting backward and forward current of the frame respectively. Pivoted to the top of the frame 2 is a handle 3 on which is a pawl or brake block 9 adapted to engage the drum. The handle may also be fitted with a slide by which it may be locked to the frame. In another form the reel is mounted on a shaft rotatably mounted in a frame at the upper end of which is pivoted a handle carrying a pawl adapted to engage ratchet teeth on the reel.
