Description

William R. Hill, 1941 S. Jefferson, Grand Rapids, Mich.
Filed Dec. 12, 1962, Ser. No. 244,086 6 Claims. (Cl. 29- 460) This invention relates to the manufacture of sign elements, or characters, and has been developed in conjunction with the production of letters and numerals used with wire suspension racks. This type of sign has come into wide use in the windows of large stores because the sign does not obstruct much of the entering light or the view out the window. The signs are readily alterable by replacement of the elements on the rack, since they merely hang in place from accurately-placed suspension hooks. These hooks are normally fixed to the sign elements, and engage the rack members.
The popularity of this type of sign, together with the number of letter and numeral elements'used with each rack, result in the necessity of mass-producing these items. Appearance is vitally important, as a flaw in the visible surfaces would destroy the effect desired. Applicant has devised a-method of manufacturing these sign elements with a uniform high quality at a very low cost. Two of the steps of applicants method are illustrated in the views of the accompanying drawing, in which:
FIGURE 1 is a perspective view showing the placement of a sign element for the painting of the reverse side.
FIGURE 2 is a view showing the support of the sign elements for finishing the display face of the elements.
Applicant has shown it most practical to begin the manufacture of the sign elements by cutting them from fiat panels of pressed fibrous material of a type commonly known as Masonite. The cutting operation may be performed either on a band saw, a sabre-saw, or router. When the elements are cut to shape and sanded, they are then placed in a conventional locating jig which will accurately place suspension hooks with respect to the upper and lower edges of the sign elements so that they will hang inproper alignment along the suspension racks. It is preferable that the suspension hooks be adhesively secured to the backs of the sign elements to avoid marring the front display surface with the heads of fastenings. The cut sign elements, with the hooks properly attached, may be considered as the rough intermediate form of the elements.
The application of exterior coatings requires a very carefully-established procedure. in order to maintain the necessary quality, and yet perform the operations with an efficient use of the workers time. The elements are first placed face-down (with the suspension hooks upward) along a generally horizontal supporting surface defined by the plane of a wire mesh. The preferred mesh configuration is a hexagonal arrangement commonly referred to as fchicken wire, and normally used as fencing. This wire mesh may either be stretched taut across an open framework, or may be laid directly upon a supporting panel or conveyor surface. The purpose of the wire mesh is to prevent capillary action from drawing the sprayed material around underneath the sign elements as they are supported during the application of the coatings. The preferred hexagonal mesh shown in the drawing should be noted closely in its relationship with the points at which the wire passes under the edges of the sign element present almost no situations in which a substantial length of wire closely parallels the edge of the sign element. This arrangement will minimize the tendency to draw an accumulation of sprayed material undersupported sign element. 'The 9,249,994 Patented May 10, 1966 neath to the face opposite from that primarily receiving the coating. In the arrangement shown in the drawing, the table structure indicated generally at 10 may be equipped with legs 11 of any selected length, depending upon the needs of the manufacturing establishment. A top framework 12 supports a panel 13, on which the wire mesh 14 is secured, preferably with staples as shown at 15. The structure of the table may be of any convenient material, ordinary wood being shown in the drawing, The panel 13 can be of plywood or of any other convenient substance.
The sign element 16 shown in FIGURE 1 is placed with the back uppermost, exposing the suspension hook 17. In FIGURE 2, the sign elements 16, 18, and 19 are shown face-up, with the hooks 17 underneath.
The first step in the coating operation corresponds to that illustrated in FIGURE 1. The normal coloring of the panels of preferred material from which the sign elements have been cut is a pastel brown, and it is desirable to paint the entire surface of the back approximately this color so that the suspension hook 17 and surrounding exuded adhesive may be colored to match the rest of the surface. The elements may either be permitted to dry in place, or they may be picked up at the suspension hooks and engagedwith some form of support for the drying operation. It should be noted that the drying of the adhesive securing the hooks 17, and possibly also the drying of the coating material on the back of the sign elements, may be facilitated by the application of conventional infra-red or other heating equipment.
When the backs of the sign elements have been properly dried, they are then placed on the supporting device in the position shown in FIGURE 2. One or two coats of a filler of a. particular type are then applied. The preferred filler includes a gum shellac, a titanium white pigment, silica gel, and denatured ethyl alcohol. It has been found that this type of filler seems to perform exceptionally well, and to exhibit very favorable drying characteristics. When the filling operation has been completed, a light even coat of fluorescent color is allowed to at least damp dry, and the second coat of this material is then added, and permitted to dry completely.
When the drying of the elements has completed sufficiently to permit some degree of contact, they are preferably placed on edge to prevent pressure causing them to either stick together or to the surrounding supporting structure. In this position, they may be stored on shelves, or in cartons or crates for shipment.
The particular embodiments of the present mvention which have been illustrated and discussed herein are for illustrative purposes only and are not to be considered as a limitation upon the scope of the appended claims. In these claims, it is my intent to claim the entire invention disclosed herein, except as I am limited by the prior art.
