Description
United States Patent 3,050,260 SPRAY GUN CARRIERS William K. Macrae and Walter Jackson, Vancouver, British Columbia, Canada, assignors to City Parking Ltd., Vancouver, British Columbia, Canada Filed Dec. 12, 1960, Ser. No. 75,322 Claims. (Cl. 239--150) Our invention relates to improvements in spray gun carriers.
The objects of the invention .are to provide a device which will support a spray gun so as to greatly facilitate the task of painting the trafiic lines at a street intersection and more particularly the lines defining the car spaces in a parking lot or the like.
Further objects are to provide suitable adjustable means whereby the paint spray being emitted from the gun is confined so that a line of a predetermined width is applied to the surface, to provide means on the carrier for controlling the operation of the gum and to provide means whereby the device may be wheeled away from a freshly painted area without smearing the lines or leaving untidy traces of paint.
These and other objects will appear in the following specification and be shown in the accompanying drawings in which:
FIGURE 1 is a fragmentary transverse section of the invention.
FIGURE 2 is a sectional plan taken on the line 22 of FIGURE 1.
FIGURE 3 is a section taken on the line 33 of FIG- URE 2.
FIGURE 4 is a diagrammatic view showing the sequence of movements for latching the paint guides in raised position and for subsequently releasing the raised guides.
In the drawings like characters of reference indicate corresponding parts in each figure.
The spray gun carrier consists of a cart having a frame which is generally indicated by the numeral 11. The frame 11 is made up of an elongated bearing 12 and integrally formed on said bearing is a centrally disposed collar 14. An axle 16 is freely journalled in the bearing 12 and said axle is fitted at each end with a wheel 17 having an inwardly projecting hub 18. Rotatably mounted on the bearing 12, between each hub 18 and the collar 14, is a sleeve 20 which is provided with a suitably graduated scale 21, see particularly FIGURE 3. The sleeves 20 each support a paint guide 24 made up of a rectangular plate 25 having a lower edge 26 which slidably engages the surface 27 on which the cart wheels 17 are supported. A split collar 28 is secured to the rear edge of each guide and the collar is mounted for sliding movement lengthwise of its supporting sleeve 20. As
shown best in FIGURE 1 the rearwardly projecting ends of each split collar 21 is connected by a clamping bolt 31 which permits the guide to be moved to any selected position on the scale 21 and to be clamped against further movement relative to the sleeve.
The collar 14 is fitted with an upwardly extending stem 34 and telescopically mounted on said stem is a tubular shaft 35 which is provided with a rearwardly extending handle 36. The shaft 35 is provided with spaced set screws 38 which are adapted to engage the stem 34 so as to lock the shaft thereto. Adjacent the lower end of the stem 34, a scale 40 is provided and the lower end of the tubular shaft is adapted to read upon the scale when said shaft is clamped in selected position by means of the screws 38.
The shaft 35 is provided with a forwardly and downwardly extending bracket 42 and removably secured to the free end of said bracket is a spray gun 43. The spray ice gun, which may be of conventional design, is disposed in a vertical plane with its nozzle 44 spaced above the lower edges 26 of the paint guides and with its trigger 45 projecting towards the rear of the cart 10. The gun 43 has supply lines 46 which are connected to a source of paint and compressed air supply, not shown. It will be noted that the supply sources could be mounted on a wheeled truck so as to follow the cart over the surface to be painted. An arm 48 is pivotally secured to the shaft 35, as at 49, and the free end of said arm is pro- 7 vided with a transversely extending finger 50, which engages the spray gun trigger 45. Extending substantially parallel to the handle 36 is a lever 52 which is secured by a hinge pin 53 to the shaft 35. The arm 48 and the lever 52 are operatively connected by a rod 54, see FIG- URE 1 only.
The collar 14 on the bearing 12 is provided with a pair of spaced lugs 57 which are connected by a hinge pin 58. Mounted on the pin 58 is a latch member 60 which curves over the collar 14 and extends rearwardly therefrom to form a release rod 61. The member 60 normally rests upon the collar 14 with the upwardly curved end 62 of the rod 61 spaced above the surface 27 Above the collar 14 the latch member is fitted with a bar 64 which is disposed parallel to the axle 16 and extends over the adjoining ends of the sleeves 20. Each sleeve 20 is fitted with a pawl 65 which is adapted to be engaged by the bar 64 in a manner which will be later described.
Assuming the device is to be used to paint a line, say six inches wide, the paint guides 24 are moved along their sleeves 20 and by reference to the scale 21, are secured in position six inches apart and equidistantly spaced from the axis of the shaft 35. The shaft 35 is also adjusted lengthwise of the stem 34 and is locked in position against the appropriate reading on the scale 40. Thus the nozzle 44 of the spray gun is positioned a distance above the surface 27 which is proportionate to the spacing of the guides so that the spray of paint ejected from the nozzle will be of the appropriate width and density when it strikes the surface.
In use the cart is wheeled along the surface and the lever 52 is moved to squeeze the trigger 45 and actuate the spray gun. The lower edges 26 of the paint guides slide along the surface 27 and confine the spray to a path exactly six inches wide.
As the line is applied to the surface the several parts of the cart are disposed as shown in FIGURE 1 and when it becomes necessary to move on to the next line the paint guides are raised in the following manner. The shaft 35 is swung forwardly about the axle 16 so that the collar 14 is rotated relative to the sleeves 20. This movement causes the latch bar 64 to ride up over the pawls 65 and to lodge in front of said pawls as shown at A in FIGURE 4. When the shaft is again returned to its normal position the guides are raised to position B. Since the lower inner surfaces of the guides are covered in paint by raising the edges 26 out of contact with the painted surface the device may be moved to the next location without leaving undesirable paint traces on the surface.
At the site of the next line to be applied the shaft 35 is rocked to the position shown at C. The end 62 of the rod then contacts the surface and this results in the latch member 60 being rocked about its hinge pin 58 so that the latch bar 64 is raised above the pawls 65. The sleeves 20 are now free to rotate about the bearing 12 and the paint guides 24 drop by gravity to position D of the diagrammatic figure.
