  • Patent number: 5158332
    Abstract: A carrier (20) for surveyor's equipment has two spaced-apart walls (23 and 25) providing a passageway (21) above and below spacers (29' and 29) respectively, for stacking laths (27) therethrough. A plunger (31) operates in two vertical slots (47 and 47') in walls (23 and 25) and exerts downward pressure on laths (27) under pressure of springs (49 and 49'), thus preventing the laths (27) from slipping out during use. Springs (49 and 49') are housed in triangular frames and are covered by plates 44. The carrier has a bin formed by curved wall (90) for holding hubs and guinnes (18) and pockets (77) for holding nails, tacks, a hand-held radio, etc. Rubber pads (63) hold the prism rod securely for long distance carrying, and clips 65 for temporary short distance carrying. An easy to grasp handle (72) and shoulder strap (70) provide comfortable means for carrying the device by hand and on one's shoulder.
