Definitions

  • Chalk powder absorbs moisture from surrounding air when the'powder is chilled by expansion of compressed air used to apply the powder.
  • the moisture also causes tubes and other conduits to be clogged, and especially tends to clog the pinhole outlets used to define patterns, preventing reliable marking operations.
  • Motorized vibration and sweeping devices and vacuum systems employed to correct these difficulties tend to prevent ready access to the work area and add to equipment cost, while at the same time requiring extra adjustment andmaintenance. In particular such added devices tend to restrict the variety and size of patterns usable, and to increase cost of pattern materials, be-
  • a very important object of the invention is to provide an improved means for producing patterns for garment marking machines of the type described.
  • a representative embodiment of the unique marker of this invention includes at least two similar, scale inter related relatively movable marking units having co-planar top frames holding perforated patterns, chutes depending from the frames and supporting collection vessels at the lower ends of the chutes; a compressed-air system having chalk powder supply pressure vessels, preferably interchangeable with the collection vessels, nozzle outlets beneath the patterns connected with the pressure vessels, and a work locating system. Paper-board pattern structure and perforation method is also a part of the invention.
  • FIG. 1 is a perspective view of the marking apparatus of this invention
  • FIG. 2 is a side elevation detail of the relation of. chalk powder projecting and collecting elements with the perforated pattern
  • FIG. 3 is a plan view of details of the marking apparatus
  • FIG. 4 is a perspective detail of a portion of the compressed air treatment and control system of the invention.
  • FIG. 5 is a detail of the back of the marking apparatus.
  • FIG. '1 illustrates in perspective the working surfaces of the marker 10 in association with the indexing indicators and control.
  • Pieces to be marked are laid on the working surfaces of the marker and chalk powder is proejcted upward through perforated patterns or projected 4, 6, 8 to mark the pieces. q
  • the marker is in the general form of a table l2 having an apertured top 14 mounting frame assemblies l6, 18, 20, which hold the respective patterns 4, 6, 8.
  • the frame assemblies are movably supported in opposed ledges 22, 24 running the length of the table on either side of the top aperture 26 to provide for individual longitudinal-position adjustment of the frame assemblies.
  • changing the pattern is accomplished by releasing a spring latch 21, opening the hinged frame assembly 20, substituting a new pattern, and closing the frame assembly.
  • An upwardly ridged stop guide 28, affixed across the top aperture 26 midway the length of the table provides a bench mark for the longitudinal-position adjustment of the frames.
  • a quickly detachable scale 30 is secured by stops3l, 33 on the table top to provide index marking symmetrically on either side of the stop guide 28 by means of grading markings 32 on the scale for determining relative location of the respective frame members and of said sheet material to-be marked.
  • Chalk powder is drawn from chalk storage vessels 52, 55, 57 below the respective frames and projected upward through the respective perforated patterns when the operator presses a control switch 46. Excess chalk is caught in vessels 45, 47, 50 beneath the individual frames.
  • FIG. 2 a sectional detail in side elevation, shows table 12, with ledges 22, 24 supporting a frame assembly 20.
  • a tapered chute 76 in the form of an inverted truncated pyramid is screwed to the underside of each frame assembly.
  • the upper, larger end of the chute forms an airtight fit around the frame.
  • the lower, smaller end of the chute ends in a plate 49 which is adapted to receive and hermetically but detachably secure a pressure vessel 50 of the type ordinarily used in compressed-air paint spray systems.
  • This vessel receives excess chalk dust collected by the chute until the vessel is filled, at which time it is disconnected and interchanged with the chalk supply vessel 52, which by that time is empty and ready for use as chalk is collecting vessel.
  • the chalk supply vessel 52 feeds powdered chalk into .compressed air received through flexible conduit 54 from an air system supplied for the purpose.
  • each frame is individually supplied with a chalk powder projection and collection system of the type described, a wide range of spacing adjustment is made available while at the same time preventing exposure of large beds of chalk to the ambient air.
  • FIG. 3 is a plan view showing the chutes 72, 74, 76 with the patterns removed.
  • the lower orifices 73, 75, 77 lead to the chalk powder collection vessels.
  • the construction of the chutes is very straightforward. Galvanized sheet steel or soft aluminum is suitably bent and joined to form the chutes with the upper and lower fittings sweated or welded in place.
  • plain panels can be fitted in the open spaces of the table top.
  • FIG. 4 shows the compressed-air treatment and control system employed.
  • Compressed air or other gas such as carbon dioxide or dry nitrogen
  • a cutoff valve 60 a filter 62
  • a pressure regulator 64 a pressure indicator 66
  • a safety pop-off valve 68 a solenoid valve 70 (controlled by electric switch 46, FIG. 1) and flexible conduit 54 to the individual frame assembly.
  • This arrangement assures even delivery by keeping each chalk powder projection system pneumatically independent of the others. Clean, dry chalk powder delivery is thus provided with maximum reliability.
  • FIG. 5 a rear elevation, details the relation of various parts at the rear of the table. Since the individual frame assemblies are relatively movable as indicated by the arrows, slots 78, 80, 82 allow the compressed air lines leading to the chalk powder supply vessels 52, 55, 57 to move and adjust with the individual frame assemblies.
  • the operator is provided with a marker of great flexibility, speed, and precision which is at the same time simple and economical to use.
  • Scale 30 is quickly substitutable by a scale having other desired markings, and, the patterns being cardboard, can be quickly made or altered using an ordinary hand-held starwheel to perforate the markings as required.
  • a powder-projection sheet material marking system having a pattern with perforations therein for passage of powder onto material to be marked and a system for collection and storage of powder projected against the pattern but not passed through the perforations, the improvement comprising:
  • first and second ledges lengthwise of the table along the respective first and second sides of the aperture
  • each frame assembly including:
  • a planar member having an opening for receiving a pattern, a pattern received in said opening, a frame securing the pattern in the opening, a chalk-powder collector chute fixed to the underside of the planar member, a first chalk-powder container having a detachable connection with the bottom of the chalk-powder collector chute for thereby collecting chalk powder, a nozzle in means for orienting sheet material to be marked including a first scale,
  • the first scale fixed across the width of the aperture in the table top, between at least two of said plural frame assemblies, thereby comprising a reference location for adjusting the position of one of said frames relative to another, the first scale having graduations along the length thereof for adjusting the position of sheet material to be marked relative to the first scale;
  • the second scale detachably affixed along one side of the table past an end of the first scale, the second scale having markings thereon in each direction symmetrically relative to the reference location provided by the first scale for indexing the location of plural of said frame assemblies relative to each other, and
