Definitions

  • ABSTRACT A carriage for use with guide means in drawing devices, in which two carrying rollers are mounted on axles stationarily secured to a base for the carriage, and two pressure rollers are mounted on axles secured to slides.
  • the slides are disposed in slots provided in the base for the carriage at an angle relative to the longitudinal axis of the carriage and interconnected by means of a resilient member whereby the pressure rollers are constantly urged against the carriage guide means to preclude skewing and playing.
  • Sheets-Sheet 1 CARRIAGE FOR DRAWING DEVICES BACKGROUND OF THE INVENTION PRIOR ART are complex in design and possess great over-all dimensions and weight. This is explained by the fact that the axles of the levers are secured on the base and the axles of the rollers are secured to the levers, which increases the height ofthe carriage and, consequently, its weight.
  • the main object of the present invention is to provide such a carriage for a drawing device, in which the rollers are disposed as close as possible to the base of the carriage.
  • a carriage for drawing devices comprising two carrying rollers mounted on axles stationarily secured on the base of the carriage and two pressure rollers mounted on spring-loaded axles movable in the plane of the base, according to the invention, the movable axles of the pressure rollers are secured to slides disposed in slots provided in the base of the carriage and disposed at an angle relative to the longitudinal axis of the carriage, with the base being essentially a plank or rectangular member.
  • the present carriage for drawing devices is simple in design, and has a comparatively small height and weight.
  • FIG. 1 is an enlarged front view of the carriage of a drawing device having a drawing head, according to the present invention
  • FIG. 2 is a rear view of the carriage and
  • FIG. 3 is a view taken along line III-III of FIG. I, the view looking in the direction of the arrow.
  • a carriage 2 Disposed on guides 1 (FIG. 1) of a drafting machine is a carriage 2 having a drawing head 3 connected thereto.
  • the carriage 2 comprises a base 4 (FIGS. 2,3) which is essentially a rectangular plank.
  • axles 5 Secured on the base are axles 5 each of which has a carrying roller 6 mounted thereon.
  • each slot 8 configuration of dovetail accommodates a slide 9 having an axle 10 secured thereon.
  • a pressure roller 11 mounted on each axle 1 IS a pressure roller 11.
  • the base 4 together with the carrying rollers 6 and the pressure rollers 11 disposed thereon are located with a protective casing 14.
  • the carriage for a drawing machine operates as follows:
  • the rollers 6 serve as carrying rollers, and the rollers 11 are constantly urged by the spring 13 against the guide I to preclude skewing and playing, while the rest of the carriage operates in the same way as conventional carriages for drawing devices.
  • a carriage for use preferably in drawing devices and adapted for movement along guide means comprising a rectangular base, first and second rollers fixedly secured to the base in axially spaced relationship in positions engaging the guide means on opposite sides thereof, said base having slots therein, each of said slots being inclined relative to the longitudinal axis of the carriage in a direction away from a fixed roller, a slide positioned in each of the slots, a roller mounted on each slide, and a resilient means interconnecting the slides so that the rollers on the slides are constantly urged against opposite sides of the guide means for precluding skewing and playing.
  • a carriage for use preferably in drawing devices and adapted for movement along guide means comprising a rectangular base, a first roller securely fixed to the base adjacent one end thereof for engaging the guide means on one side of the longitudinal axis of the carriage, a second roller securely fixed to the base adjacent the other end thereof for engaging the guide means on the other side of the longitudinal axis of the carriage, said base having a slot adjacent said one end thereof inclined relative to the longitudinal axis in a direction away from the first roller, a second slot adjacent the other end of the base inclined relative to the longitudinal axis in a direction away from the second roller, a slide positioned in each of said slots, 'a roller mounted on each slide, said slide mounted rollers engaging said guide means substantially opposite the first and second rollers, and a spring interconnecting the slides so that the rollers on the slides are constantly urged against the guide means for precluding skewing and playing.
