Applicationfiled November 17, 1925. Serial No, 69,610.

M present invention relatesgenerally to coating materials and more. particularly to aprocess and apparatus for producing a predetermined ornamental efiect upon material,

such as a feltbase, intended to serve as a floor covering andco-ordinately involves a process and apparatus for the continuous production of rugs, from a strip of such material.

One of the objects of the invention is the production of a field coating-for a floor coverin and more particularly for a felt base rug 1n which shall be embodied a number of colors so treated as to cause them to be shaded ofi and to commingle and more particularly the production in such a field in addition to thecolors originally deposited, of additional colors resulting from the manner of treatment of the colors so originally deposited.

J The employment of applicators having predetermined impressidn surfaces such asprinting rollers or blocks for producing predetermined designs upon a door covering surface is not only inconvenient and expensive because ofthe necessity of employing a differout a plicator for such design, but in addition, have found that effects such as marbleizin or wood graining cannot be eiiectively pror need with applicators of this character not only because of the'fact that there is a limit to the number of colors that can be employed practically, but aise because of the fact that marble or wood graining efiect necessitates the intermingling of shades and tints which cannot possibly be attained by these methods or the employment of such apparatus. 0 Neither the mash block process nor a pr nting roller process can po ssibl give a shading off or merging of one color into another be- .cause of the fact that even though successive colors are merged, the will be merged at a time when one has reac ed a greater degree of dryness than the other and furthermore 1n the use of a printing roller, its action is to suck up the paint with it as it moves away from the printed surface. a

On of the objects of my invention 1s the production of an ornamental surface upona floor covering or similar material in which I tors I dispense with the em loyment of applicaaving surfaces 0 predetermined conformation or contour and intended to produce corresponding predetermined design impressions upon the surface of a floor coverto a great extent upon the relative movement between the material being ornamented and the applicators, and more particularly an arrangement whereb paints so deposited are treated to cause t e difierent colors where different colors are used, to shade off into each other and at times to intermingle and produce new tints so as to enhance and more efiectively approach the desired marbleized or wood graining efiect. 7

Another object of myinvention isthe provision ofan arrangement whereby the colormg materialto form the field of the rug or floor covering is applied by applicators made up of standardized units arranged to discharge upon or supply material to the surface to be ornamented, the units being so arranged as to be capable of dischargin variably upon difierent portions of the sur ace so that any unit or group of units discharging upon predetermined determined :design.

In the apparatus herein described, I show broadly the employment, for the production of the body or field coating on the strip or web of material, of a series of standardized units, each of which serves to control the application portions will give a pre- 'ing, such as a felt base product, of which of a coating material to predetermined'areas of the surface to be coated so that by a change in the units or by a change in the predetermined portions of the surface upon which each unit deposits, an unlimited variety of designs canbe produced'incident to the relative movement between the surface being ornamented and the units of deposit.

The deposits forming such field will be arranged generally longitudinally of the predeterminedly or otherwise, so as to causethe lines of deposit while running generally lengthwise. of the material to undulate.

Another object of my invention is the treatment of these lines. of deposit forming the field so as to cause the coloring matter in one or more lines of deposit to spread beyond the original area upon which they have been deposited to cause not only a shading ofi in the color deposit but also in commingling of adjacent deposits whereby new tints or shades are produced.

My invention further provides for an arrangement by which each unit can be given movements laterally of such direction of movement of the surface being treated to simulate a graining eifect so that by the movement of one or more, units, each of which may control difierent colors where so desired, a varied colored graining effect may be produced by the compound relative movement of the units and the surfaces to be coated and in my preferred embodiment, these units are in the form of a series of controlling elements, each of which is characterized by the differ ential positioning of the point of discharge of the material thereby upon the surface being treated so that by varying the point of discharge of the element of each unit and by combining these units differentially, any desired character of deposition can be attained;

A still further object of my invention is an arrangement whereby a rug border can be applied to a strip of felt base product or the li e, while the strip is in motion, and my in vention involves an arrangement whereby the rug border is produced by an lmpresslon member having thereon an lmpression surface to form a complete rug border or to form complete the complete single color impression for the border.

A still further object of my invention is the production of rug repeats from a strip, while the strip is in motion, and this phase of my invention involves an arrangement wherebythe body coating or field is" applied uninterruptedly to the strip while the strip is in motion and the rug border also applied while the strip continues to move.

A still further objectof my invention is the successive applications of rug body and rug border ornamentations, so that one is applied before the other is.completely dry so that the disadvantages of the application of a second coat upon portions only of a coat which is alreadydry, will be avoided.

Another object of my invention is the production from a continuous strip of material of rug repeats by applying to the strip a continuous uninterrupted body or field ornamentation then superposing thereon ornamentation to not only predetermine the rug lengths but also provide the rug borders for each length.

In accordance with my invention, I first apply a rug body coating to the strip of felt base fabric, which may be uninterrupted and which may be produced by the manner already referred to above and to be more fully described hereinafter, although as will be understood while this character of field and its manner of its production is not essential to this-phase of my invention, it nevertheless possesses decided advantages. I then employ an impression member such as a printing roller to apply the rug border the impression member beingof such a character that each operation thereof produces an impression for at least a full rug length.

My invention further involves the process and. apparatus whereby the field coating applied to a strip shall be not only of a character but of such dimensions as to permit porgions thereof to form the field of the rug bor- In accordance with the embodiment of my apparatus herein disclosed for practicing my process, I show a plurality of sources of supply for the different characters of coating material and elements in connection with these sources of supply, adapted to cause the material from said source of supply to be therewith are each shiftable either together with or independently of the units and transversely of thedirection of movement of the web so that having predetermined the relative positions of the elements in each unit with reference to each other, the deposit from each elementof each unit as the web is moved along will be generally in a direction longitud'inally of the web and the line of deposit by ear-h element will be determined b its position with reference to the edges of the web and the character of deposits by each unit will be determined by the relative positions of the elements of each unit with reference to each other and the lines of deposit can be varied to cause them to undulate by a transverse shifting of the units. con-- nection with this, I employ an element which I term the spreader, the effect of which is not only to even off the upper surface of the deposits but which will also spread each line of deposit beyond its original area of deposit so as to cause the different materials.

deposited along the lines as indicated to shade oil and also to cause adjacent deposits to commingle, and with the proper selection of colors, such commingling can be caused to produce newor additional shadesor tints.

This coating so produced, which I will term the field coating is preferably deposited on the strip for the full width thereof and is an uninterrupted field coating. I then employ an impression member which is illustrated in the drawings as being one or more impression rollers, for impressing directly on this field, the-rug border the size of the roller and the impression surfaces thereon being such that one rotation of the roller will produce an impression for the full length of the rug which itis desired to produce. It

anism will be observed that in this manner, the first coating'which forms as stated the field coating will also appear in the border.

For the attainment of these objects and such other objects as may hereinafter appear or be pointed out, I have illustrated embodiments of my apparatus for practicing my process, in the drawings, wherein:

Fig. 1 is a top plan view of the apparatus for practicingmy process;

Fig. 2 is a side elevationalview thereof;

Fig. 3 is a side elevational view partly broken away of a portion of the apparatus showing the details of the knife or spreader mech- Fig. 4 is a perspective view on an enlarged scale of one of the coating units; and

Fig. 5 is a view similar to Fig. 3 showing a sli ht modification.

Before proceeding to describe my invention, I will state that my process .involves the treatment of a web of material such as fclt base to'cause a coating to be deposited thereon which coating 1 will term the body coating and also contemplates the application I along with said coating of a second form of ornamentation which serves not only to predetermine rug lengths but also to form the border of such rugs and I will first proceed to describe process and apparatus for producing the body coating.

It will be understood however that while in the present apparatus the body coating is used as such in connection with a rug, this is not essential as it may equally be employed in connection with the manufacture of runners, and in fact can serve as the sole ornamentation for a floor covering.

Upon viewing Fig. 1 of the drawing,'it will be observed that my process is to be employed in connection with the coating of the surface 10 of any preferred or desired material 11, such felt base floor covering, which is fed from a source of supply suchas a roll 12 along a bed 13 in any preferred or desired manner and my apparatus, disclosed in that figure for employing my process, comprises generally a series of controlling elements, any number of which may be employed, as will be fully understood later on, and each of which is intended to control the deposition of a material upon a surface, the controlling elements being so associated as to cause each element or predetermined combination of elements to give a predetermined ornamental effect, and the charge in the elements or combination of elements to vary the ornamental effects. \Vhere the application or deposition of the same material to a surface is controlled by more than one element, I employ in the illustrated embodiment of my invention, a single source of supply for such coating material and have associated together the elements supplying such coating material and will these units is illustrated on a large scale, it

will be seen that each of the units comprises a member 16 which is illustrated as in the form of a conventional type of container within which dips the feed roller 17 mounted to rotate with the shaft 18, carried in the bearings in side walls of the container 16. Mounted upon an end of the shaft 18, extending beyond the container is the driven member '19 which maybe of any preferred or desired character, such as a pulley or gear, and is driven in any preferred or desired manner, and to be-.more fully described hereinafter, so as to cause the roller 17 to be given a continuous rotation so as to feed the coating material contained in the receptacle 16. To provide a uniform feed of coating material, I employ a doctor or wiper member 20 pivoted at 21 as shown and so arranged as to normally gravitate against the pulley so as to predetermine the amount of material carried on the surface of the roller 17, it being understood that the roller is driven counterclockwise as shown by the arrow.

'Mounted in advance of the roller is the rod 25 which is carried in the pintle hearings or ears 26 extending forwardly from the frame, the rod 25 being mountedin these ears 26 as to be freely slidable therethrough. The rod 25 is held against rotation in its bearing 26 as by apin and keyway connection 26'.

. Upon thisrod 25 ismounted a series of elements which I will term the controlling and applying elements and which can .be

vari'ed considerably from the illustrated embodiment to perform the function which it is desired it shall perform. In the preferred embodiment illustrated in the drawing, these elements are all shown as duplicates of each other and a description of one will therefore suffice for all. Each controlling element comprises what might be termed a funnel defined by the floor or bottom 31 and the opposite side walls 32 and 33. These side walls approach each other toward the lower or front end of the elements 30 so as to provide a tapering channel or passageway therebetween. These walls gradually decrease in height toward their rear ends 34 and 35 and merge into the rear edges 36 of the controlling element or funnel 30. Extending downwardly from the lower wall 01' bottom of the elements 30 are the cars 40 having openings therethrough which can be received the rods 25. r

From the description thus far given, it will be understood that the controlling elements 30 are mounted on the rod 25 both for a swinging movement thereabout and also for a sliding movement with reference thereto and for preventing the accidental occurrence of such movements, I provide an arrangement such as the extension sleeve 37-having an opening therethrough to receive a locking member such as a screw 38, threaded therein and arranged to abut against'and lock the element 30 to the rod 25. The lower wall 31 of each of the elements is preferably, although not necessarily, curved as shown in. the drawings and the rear edge 36 thereof is so arranged and constructed that when positioned to contact with the surface of the roller 17, this edge 36 will lie "flush and in scraping engagement therewith.

The rollers 19 are driven in any preferred or desired manner as by friction rollers 50 mounted on a shaft 51 driven by the gear 52 in mesh with the gear 53 driven by the motor 54.

From the description thus far given, it will be understood that the number of units employed corresponds to the number of differently colored coating materials which it is desired to employ, one vunit being employed for each coating material and that the number of lines of deposit of each coating material which it is desired to apply,-predetermines the number of the elements 30 which are rendered operative, the rest of the elements associated with each unit being moved to the inoperative posltion as shown with some of the elements in Fig. 4 of the drawing.

The position which it is desired that the lines of deposit shall have with reference to the side edges of the fabric 10, predetermines the positioning of the elements 30 on the rod 25, these elements being ad ustable longitudinally thereof in the manner already described.

As already has been explained, the surface 10 to be coated is moved continuously Lbeneath these containers so that the discharge from each element 30 will in effect produce a line of coating in the direction of movement of the fabric and longitudinally thereof. The number of lines produced by each container, their position with relation to the side edges of the material and their spatial relationship, will be determined by the number of outlets in each unit container and their relative position in the container not only with reference to the container but also with reference to eaclr other.

The thickness of the lines or the amount of material deposited at any one point in a A line will be determined by the size of the discharge mouths of the element 30 and the action of the roller 17 and the doctor 20 and also the character of the material employed. By employing in the different pans materials which vary from each other, either as to consistency or color, acontrast can be produced between the groups of lines produced by any one predetermined container and the groups of lines produced by other containers and it will therefore be understood that by associating together different units, that is units which have different characteristics with reference to the elements as to their number, size and position or by varying the material controlled by the units an infinite number of contrasting lined designs can be produced.

The design thus far described is what 1 might term a straight line design and in order to give an effect such as is found in marble or in wood graining, I provide in my apparatus for a movement of the controls 30 at an angle to the direction of movement. of the fabric 11 and as in the illustrated embodiment, these outlet controls 30 are fixed to the rods 25, I attain my object by providing that a corresponding movement be antomatically given to the rods 25 ,in the manner which I will now describe.

The rods 25 are each provided preferably at the end adjacent its driven member 19 with an extension 27 to which is fixed the sleeve 28 having mounted thereon the pin 28' arranged to receive in the cam slot 29 formed in the driven member 19.

It will therefore beunderstood that, as the driven member 19 rotates to feed the material to the controlling elements 30, which in turn discharge such material upon the surface of the saturated felt base 10 upon which the ornamentation is being formed, a movement will be given the units and along therewith to the elements of each unit, laterally of the web 10 and transversely of the direction of the feed thereof. The character of the slots 29 and the speed of lUtl lit)

meamo trolling element and by varying the charac- 'ters ofthe cam slots 29 relativelyto each other, not only can the undula'tion of each controlling element be varied, but an infinite variation in the movements of th econtroh ling elements 30 with reference to each other can thus be attained. Furthermore, by having one or more of the driven elements 19 provided with slots which are merely guide slots and have no cam action, an enhanced efiect can be produced because of the contrast between the undulating lines of deposit and straight lines of deposit.

, While by my processthus far described, I am enabled to obtain highly ornamental effects such as'the simulation of marble and 20 Wood aining, yet I find that the lines of the di erent coatings are rather too sharply defined and of too uniform a character transversely thereof to make such effect complete and my process further involves a treatment of the material after it has been deposited so as to eliminate the sharp definition of the lines of deposit and also to shade them 011' and also to cause adjacent colors to combine,

and in Fig. 3 of the drawing, I show for this purpose the knife or wiper member 40 which may be of any desired configuration, character or material and which in the illustrated embodiment is shown as carried by the rod 41 mounted to have an up and down movement. For lifting the wiper or knife member 40, the rod 11 is connected at its npper end with the free end of the lever 42 so as to have a loose pivotal connection therewith, said rod or lever 42 being pivoted intermediate its ends to the top frame member 43 as shown at 4A, the opposite free end 45 of the lever 42 serving as an operating handle portion. In order to cause the knife or wiper member 40 to apply sufficient pressure to the surface of the material being treated, I provide any desired number of spiral springs 46 encircling the rods carried and projecting upwardly from the wiper or knife member 40 and guided through the top frame member 43. These springs 46 abut in nuts 49 adjustably carried by the rods to give any desired pressure to the.

knife or wiper member 40 upon the material that is to be treated.

The knife 40 extends transversely of the direction of movement of the material 10 and is atleast of a lengthequal to the width of the material and is positioned as will be observed upon viewing Fig. 5 of the draw-' ing, a distance beyond the point at which the coating material is deposited on the surface 11 by the applicator units. As the lower edge of the knife contacts with the lines of deposit, it will have what might be termed a spreading efiect which will not be uniform particularly as to those lines which undulateand the result of this will be to cause these lines of coating to spread beyond their original areas of deposition and closely approximate and simulate the graining in wood or a marble effect.

I have found that the use of a steel spreader such as that shown at 40, is extremely efi'ective for the results desired. The steel knife spreads the colors evenly and thus gives to the coating a smooth, even surface due to the absence of any suction such as is present when an extended surface such as an impression member is moved relatively to the coating deposited b it. In addition, the spreader acts to force t e paint into the material and therefore gives to the floor covering not only an ornamental coating but a highly efi'ective wearing surface. I have further found that not only is the merging of colors almost im-- perceptible, but that by the employment of for instance, six colors, any number of additional colors or tints can be produced.

The strip of material is fed from ofi the roller 12 by the suction roller 90 and as my invention contemplates that where desired the process and apparatus hereinbefore described may be employed to form rugs from a strip orweb 10 by a continuous process,I show the association of such apparatus of rug border applicating means so arranged and as sociated that the rug repeats canbe formed from the strip in one continuous process. The web is fed from the suction roller 90 into a well 91 to provide anexcess length of the strip between the feeding mechanism of the apparatus for producing the field thus far described and the feeding means of the rug border applicating means to be now described. The strip coating as set forth is fed through the border applicating means in any preferred or desired manner, as by the end less belt 92'which may have associated there- ,with pins (not shown) or any other form of web grlpping means. In theillustrated embodiment, I show my rug applicating means as constructed to form a two color border and for this purpose, I use two impression rollers 100 and 101 to the surface of which coloring material is applied by means of the rollers 102 and 103 contacting with-the rollers 104 and 105 which dip into the color pans 106 and 107. The impression rollers 100 and 101,

.each has thereon impression surfaces which outline a complete border and the circum- 'ference of the roller is preferably made will provide rug border impressions which in turn-Will merge into each other so that when the rugs are cut apart, the lines of cut will be midway through this and rug border impression areas. \Vhere on the other hand, it is desired that a space shall be provided between the rugs. this can be arranged for by increasing slightly the size of the roller, making the continuous rug border impression surface of less length than the circumference of the impression rollers, thus causing the ends of such impre3sion surfaces to be spaced apart a short distance which in turn, will produce a space in between the rug repeats.

One of the important features of my 1nvention is the fact that I produce a field coating which is continuous forthe full width of the rug which it is desired to produce and where the width of the rug which it is desired to produce is equal to the width of the strip, also for the full width of the strip.

As a result of this method, the ru border is impressed directly upon the b0 coat so that the coat which forms the field of the rug merges into and forms part of the border so that by properly predetermining the ornamental association of the border in such field coat, not only is a highly ornamental border produced as well as a contrast between the border and the field coat, but in addition, there will be an ornamental relationship between the field coat and the border with which both the continuity of ornamentation and the contrast is effective.

In Fig. 5 of the drawing, I show a modified embodiment of the knife support in which the spreader knife is carried by a threaded post which engages through a corresponding threaded opening in the top platform 61 so as not only to be able to render the spreader operative and inoperative, but also to be able to adjust the pressure ,thereof.
