Theejector mechanism of the present 111- vention is basically novel,-in that it provides,

' for the first time, a universal type of multiple unitejector composed of a pluralityof independent sub-ejectorsadapted to function. either singly or collectively. The mechanlsm consists essentially of 'anejector block, a

major sub-ejector andone or more minor subejectorsmounted in operative relation. Each sub-ejector isadapted to function independently to eject and deposit an lnlay of a different configuration, or the three componentsof a single complete ejector may functioncollectively to eject'and deposit a unit inlay.

lays.v The following is a description of a preferred embodiment'of the invention, refere j ence being madeto the-accompanying draw A ings. A I A A A I g The-ejector block.

The ejector. block 20, Figures, IV and V, is

usually formed ofbrass and is provided with an offset and projecting port-ion 21, adapted to be press-littedinto a cooperating] recess in the'cuttmgand inlay ng cylinder 10; The

block is drilled'to pr'ovideapluralityof spindle openings 22, 23, and 24, the opening 22' being concentric witli'the axis of the projec tion.2l and the latter twobeingpositioned' relatively thereto as illustrated. Spindle guideways 26 are out adjacent each opening and the openings 23 and 24; are also counter bored to provide spindle retainingshoulders' 25; The block is slotted at'27 and 28 to provide recesses for the reception of cutting knives, andalso at 29, 30, 31, and 82 to providefiexible sections 33and'34 adjacent the. spindle openings 23 and 24' respectively, for the purposehereinafter described.

, The major sub-ejecto1r The major sub-ejector, .Figure VIII," is

Apreferably constructed in the manner described and claimed. in United States Letters Patent 1,784,487, granted December "9, 1930.

opening The bushingis also centrally bored to provide an opening in which the ejector spindle l2 slides. The spindle isprovided with a collar 37, working"within the inner. end of theopening 22., Between the bushing 36 and the collar 37 is. confined a light coil spring 38 which'serves to retract the spindle after it has been pushed outwardly by thepat} tern or inlaying rolls. To guide the spindle in its reciprocating movement and to prevent its rotation, projecting lugs 39 are formed on the collar 37 and are adapted to slide in the longitudinally extending guideways 26. The spindle 12 is threaded at its outer end 40 and is provided with a shoulder 41. The ejector plate'42 is perforated and engages the stem of the spindle, abutting the shoulder 41.

The plate 421's counter-bored to receive a round slotted nut 43 which threads onto the 15 and spindle.

The minorsub-ejectors The minor sub-ejectors are substantially identical with each other in construction almthough the ejector plates are of different con figuration. Ea'ch'sub-ejector comprises a spindle 47-and an ejector plate 48 (or 48) swaged onto one end of the spindle. Each spindle, intermediate its length, is provided wwith an enlarged collar portion 49 adapted to slide within the counter-bore of opening 23-or 24, but to engage the shoulder 25 of the block 20. Each spindle is also provided with strengthening ribs sliding within wthe guideways 26 and serving also to prevent rotation of the spindle duringits reciprocat ing'movement. The minor sub-ejectors are positioned within the respective openings 23 and24 in the block 20 by forcing the collar siiportion 49 past the shoulder 25, the flexible sections 33 and 34 yielding to permit such passage. Thereafter the sections 33 and 34 return to normalposition and prevent the escape of the spindles so that, in operation, each spindle is limited in its outward move ment by the engagement of the enlarged collat-portion 49 with the fshoulder25. When, however, it is desired to dis-assemble the ejector, eac'hspindle 47 may be withdrawnby 4s' springin forcing t e collariportion 49 past-the shoulder 25. Tapped holes 51 are provided to facilitate this operation.

Tlw ejector assembly The several sub-ejectors, when assembled with the block 20 in the manner described,

form a complete multiple unit ejector mecha nism of universal type. It will be observed 55 that the ejector plates 42, 48 and 48'. are each of different configuration, but when assembled, form a complete unit which is of square configuration. vItwill also be noted that the the flexible walls 33 (or 34) and ejectors, a single plate of such configuration may be mounted on the spindle 12 of the major sub-ejector and the plates 48 or 48' or botlfi, as the case may be, may be dispensed wit Automatic equipment for the manufacture of inlaid linoleum or the like, usually comises anumber of cutting and inlaying cylinders lO, each cylinder havin assembled on its periphery a plurality o the ejector mechanisms. One'form of assembly of the inlaying'ejectors llofthe present invention is shown in Figures 1 and 2. Cutting knives 52 are interposed between the adjacent ejector mechanism and also in the slots 27 and 280i the ejector-block 20 between the plates 42, 48and 48' of each ejector. It willof course be understood that where the inlays to be cut and deposited are of a configuration embracing a plurality of contiguous ejector plates, the cutting knives between such iplates will be removed so that the inlays may be cut and'deposited in unit pieces. Within the cylinder is positioned'a pattern: roll- 13, the surface of which is provided-with a'p'lurality of recesses 14 conforming to the desired inlaid-pattern. As the cylinder 10 rotates, certain of the ejector spindles enter: the recesses 14 thus permitting the cone-.- sponding pattern tess'erae '17 to be retained.

The ejector spindles not entering recesses on the patternroll are forced outwardly by the latter and eject the material between the retained tesserae, the ejected material being, swept away by the brush 15. As the cylinder 10 continues its rotation the ejector spindles 12-are operated upon by the smooth surface inlaying roll 16, also positioned within the cylinder, and the "initially retained tesseraa 17 are ejected and deposited upon a suitable backing 18in patternrelation. It will be apparent that by employing diflerent' pattern rolls 13 in which the location of the recesses 14 is varied, the universal multipleunit ejector assembly is adapted to produce an almost-unlimited number of distinct patterns.- 7

Another most important feature ofthe' present invention is that the ejector mecha nism constructed in accordance with" its teachings, iscapab'le of cutting and deposit-:

ing inlays of very small dimensions. Thus, the majorsub-ejectoris adapted to deposit an inlay having a minimum dimension of ap proximately one-half inch while the minor sub-ejectors are adapted to deposit inlays having a minimum width of about one-eighth inch and a length corresponding to the minimum dimension of the major sub-ejector. Thecapacityto accomplish these results remarkably increases the scope of patterns which may bemanufactured with automatic equipment provided with such ejector mecha nism.

In addition to theabove enumerated ada vantages, the ejector mechanism ofthe prose;

ent invention is both simple and rugged in construction, and positive and safe in opera-. tion. Repairs, when necessary, are greatlyfacilitated by the manner in which the ele' ments of the mechanism are assembled. Any

sub-ejector of a single mechanism may be removed and replaced without disturbing any other element of the mechanism. Similarly, any ejector mechanism may be removed and replacedas aunit without affecting adjacent mechanisms;

' It will be apparent to those skilled in the art that this invention contributes an important advance in the manufacture of inlaid linoleum in that it provides, for the first time, a universal type of multiple unit ejector mechanism for'cutting'and depositing inlays.

In theteaching of the construction of a mechanism of this character,'the present inventor I I asserts his pioneership.
