This invention relates to the manufacture of linoleum by the molded inlaid process. It is a continuation-inpart of my application, Serial No. 119,694, filed June 30, 1926. y In the manufacture of linoleum by the molded inlaid process, a burlap backing suitably supported is moved along a supporting bed in a step by step manner, and the various pattern elements are built up thereon by applying linoleum mix in granular form through suitable stencils. The linoleum mix employed has many peculiar properties. The granules or particles tend to cling together. They will not flow like dry sand will flow, for example. If shaken or brushed through an opening they will build up in a shape corresponding to the shape of the opening, but will not spread sidewise. The

stencils employed are spaced apart a distance so that the several mixes applied through the different stencils will be in proper relative position on the backing. After the mixes have all been applied, the goods are subjected to high pressure to compact the mixtures. Up to the time that the pressure isapplied, the linoleum mixes `lie on the backing as a loose furry mass, and the goods must be very carefully handled. Any vibration tends to tumble the placed mixes over into shapeless piles, andthe design is destroyed.

By reason of the fact that the material must be handled so carefully, provision is made for very gradually accelerating and decelerating the burlap in its step by step movement, and in order to secure registration it is desirable that the number of stations be as few aspossible having in mind the particular design to be produced.

In practice it is found to be most desirable to brush or strickle the mixture through the stencils by hand labor. On some designs it is possible to have one plate man operate two stencils, but ordinarily one man is employed for each stencil on narrow goods and two men are employed for each stencil` on the wider material.

1929. `Serial No. 363,758.

for each of thesefbright colors. If the haphazard `spots in the design each consisted of two colors, each separate from the base colors and from one another, it would be necessary to `provide twice as many additional stencils as if only one color wereA employed in each of the several haphazard spots. All

of this would greatly lengthen the machine and increase the cost thereof, and would also increase the operating expense.

"I provide for applying a plurality of stencils each adapted to supply one color to r the base. The haphazard spots in the design will be applied at `one or more stencil stations, the plates of which are sub-divided into compartments so that different colors may be brushed through different stencil openings.

In wide material it may be impossible for one man to reach entirely across the material and brush in the color, and I therefore provide a supporting platform over the stencil so that a man may work thereon and brush in all of the colors.

In the accompanying drawings, which illustrate the present preferred embodiment of my invention as applied to the making of a tile design,

Figure lis a vertical longitudinal section, largely diagrammatic, illustrating a machine embodying the invention;

Figure 2 `is a top plan view to enlarged scale of a portion thereof;

Figure 3 is `a top plan view of one of the divided stencils, a part being broken away;

Figure 4t is a section on the line IV--IV of Figure 3; and y Figure 5 is a view showing a portion of another divided stencil to be used with the stencil of Figure 3.

A molded inlaid machine comprises a supporting bed, indicated generally by the reference character 2, having an endless carrier 3 extending` therealong. This carrier is of the form generally employed in machines of this type and needs no detailed description. On its upper run the carrier supports a strip of burlap which forms the backing for the linoleum.

The stencil trays are arranged at spaced intervals along the bed 2. The trays at one end of the machine are indicated at 4, 5, 6, 7 vand 8, in Figure 1. The material moves in the direction of the arrow of Figure 1. The trays are mounted in the usual manner on lifting devices, not shown, so that they may be raised when the burlap backing is advanced. As is well known, color is strckled through the stencils, the stencil plates are then lifted, the material is moved forward a distance corresponding to the repeat length of the pattern, and the stencils are then again lowered for the application of additional color.

The stencils 4l, 5 and 6, as well as those preceding them in operation in the machine, are arranged each to supply a single color to the backing. Figure 2, at the left hand end thereof, shows the material as it appears when it is on its way from the stencil 6 to the stencil 7.

It will be noted that there are four blank spaces, numbered 9, 10, 11 and 12, in this particular design. The space 9 is to be lilled with a design consisting of a shield 9a and a surrounding field 9b, the colors of the design elements 9a and 9b differing from the colors of the tiles in the background. Similarly, the space 10 is to be lilled in with a conventional design of a ship; the square 11 with a conventional design of a castle, and the square 12 with a conventional design of a helmet. It is desirable that various colors be used in these different designs and the fields therefor. The stencil 7 is provided to lill in the designs proper in the squares 9 t0 12 inclusive.

The stencil plate is divided into four parts by vertical partition Walls 13 so that eachV of the stencil openings 9p to 12p for forming the brightly colored patterns lie in separate compartments. The stencil plate 8 is similarly divided by partition walls 13 so that the lield'stencils 9f to 12]c inclusive lie in separate portions of the stencil plate. It will be noted that in each case the stencil opening is spaced away from the partition walls and is of a shape corresponding to the design element to be laid down. This is important as there must be a clear space around the stencil opening to allow the plate man to run a scraper thereover and scrape off the material to the height of the stencil plate.

Figures 3 and 5 show the stencil openings with the usual wires 111 therein.

Platforms 15 are arranged above each of the stencil plates 7 and 8. It will be noted from Figure 2 that the platform lies over a partition wall 13 and is clear of any of the stencil openings so that one man can work from this platform with all of the openings in his charge in clear view. In wide material it is impossible for a man to reach all the way across the machine and ll in color through the stencil openings. However, the amount of work which 'is done in applying color through these small openings is so little that two men operating a single stencil are not kept busy. By providing the platforms shown, one man can operate the entire plate successfully.

As above stated, the stencils are raised so as to permit of the movement of the material thereunder. The platforms 15 may be fixed or may move upwardly with the stencils as desired. Ordinarily they will be supported from the ground and will be spaced a su'i-I cient distance above the bed 2 to permit of the stencils being raised in the desired amount. The only movement of the stencils is in the vertical direction. They are fixed against horizontal movement because the adjustment of the stencils so as to insure proper register must nearly always be preserved. Therefore, while they may be preliminarily adjusted on their elevating mechanism so as to properly fix their position relative to the other stencils, they do not move horizontally during operation.

By the use of my invention highly desirable effects may be obtained at relatively low machine and operating costs. l have ilite lustrated and described a present preferred embodiment of the invention. It will be understood, however,'that it is not limited to the form shown but may be otherwise embodied or practiced within the scope of the .following claims.
