Thus there are only three operations with which the draftsman must contend in normal operation of his machine: (1) parallel motion, (2) base-line setting, and (3) angle setting. VEMCO standard-size machines with either Standard (Models 2100 and 4100) or Civil Engineer's (Models 3100 and 5100) heads, as well as VEMCO compact-size machines (Model 3300 and 3500) achieve parallel motion with a band-and-pulley linkage from the clamp to the head, VEMCO V-Track drafting machines accomplish this purpose with two carriages moving in mutually perpendicular tracks. For information on these machines, please request brochure. This booklet describes the installation, operation and adjustments of the VEMCO Models 2100, 4100, 3100, 5100, 3300 and 3500. The 2100 and 4100 are identical except that the latter is equipped with VERSATILT counterpoise, a spring counterpoise for use on tables inclined up to 25 degrees. The 3100 and 5100 models are, respectively, the same as the 2100 and 4100 except that they have protractor heads, which are especially suitable for civil engineering work and are, therefore, called Civil Engineer's machines. The 3300 and 3500 are smaller (and less expensive) machines, which, however, are built to the same standards of precision as the larger 2100. It also has a brake at the clamp and is thus suitable for use on horizontal, or boards inclined up to ten degrees. Unless one is already familiar with the operation of VEMCO elbow-type drafting machines, the user should read the sections of this booklet entitled "Preparation for Use" and "Operation." The sections on "Adjustments" and "Maintenance and Repairs" deal with adjustments that, if the machine is treated with care will arise very infrequently. Although the illustrations in this booklet were prepared showing the 2100 (or 4100) machine, the mechanisms of the 3300 and 3500 are so similar to those on the larger machine that the user of the latter drafter will have no difficulty following the instructions given herein. V EMCO MODEL 5100 The VEMCO 5100 drafting machine is perfect for engineers, architects, professionals and students who require precision in their work. The main purpose of VEMCO’s 5100 is to set off accurate angles in respect to a line, which may occupy any azimuth in an entire circle. The protractor is divided in half degrees and is marked 0-360 degrees in addition to the usual 0-90 degree quadrant numbering. And the vernier permits readings accurate to one minute instead of the common 5 minutes. Additionally, the machine is equipped with a magnifying glass for easier reading and a micrometer knob and gear to permit precise angular settings. It also has VERSATILT’s counterpoise spring that allows it to be used on tables inclined up to 25 degrees. The VEMCO 5100 can be use in any board up to 36 “ x 60”.
