ASSIGNORS TO OXFORD VARN'ISH CORPORATION, OF DETROIT, MICHIGAN, A. OOR- PORATION OF MICHIGAN APPARATUS FOR-DECORATING INSIDE SURFACES OF FRAMES AND THE LIKE Application led J'uly 17,

This invention is concerned with an apparatus for decorating articles, such as hollow frames, on the interior surfaces thereof, an example of such work being sheet metal window frames for closed automobile bodies. These frames include substantially contiguous sides which, for the desired inside surface inish, may have imparted thereto a wood or other grained pattern effect. The hollow frame units are of various sizes and sometimes various shapes; usually they are rectangular and completely Closed on all four sides,'that is, all sides are contiguous with two adjacent sides. Frames of this sort have previously been grained on their inside surfaces by tedious hand methods with more or less success, but it has been found practically impossible to hand grain such frames on a high production basis.

An object of this invention is to provide an efhcient apparatus for decorating the inside surfaces of generally hollow articles. By the terms hollow, or generally hollow articles, as herein used, U-sh'apes, etc. are included.

Another object is to provide an eicient machine for decorating, specifically, graining, the inside surfaces of metal frames having continuous or substantially continuous side members.

Other objects and features of the invention will become apparent from the following description relating to the accompanying drawings, showing the preferred forms of the apparatus and machine and illustrating the various steps of the method as prefcrably practiced. The essential characteristics are summarized in the claims.

is a sectional detail view substantially according to the line 5-5 on Fig. 4; Fig. 6 is a detail view showing certain other scraper mechanisms, the section being taken substantially along the line 6--6 on Fig. 2; Fig. 7 is a detail view of a portion of the work support and guide arrangement in substantial accordance with the line 7--7 on Fig. 2; Fi s. 8 to 11 are diagrammatic illustrations of-t e preferred sequence of steps in carr ing out the method; Figs. 12 and 13 are iagrammatie plan views of still other forms of apparatus or machines by which the method may be carriedv intol effect, and Fig. 14 is an exemplary plan view of a different form of frame, such as maybe grained or decorated in accordance with the invention.

In general, the method of handlingholl tion is effected, will move the frame fromone position to another relative to the support and will finally free the frame, allowing the latter to be shifted to a different position on the support for subsequent engagement by rolling contact with, for example, another segment. In this manner, all the inside surfaces of the frames may be grained, notwithstanding the fact that some of the elements or sides of the frames are of different lengths, in fact. shapes. The machine is arranged to adequatelysupport the frames in easily handled position, and a feature of the machine is that all of the pattern transferring surfaces of the segments are effectively cleaned of excess pigment material and new pattern effects placed on the transfer surfaces in an ex editions manner. Further refinements inc ude the provision of cleaning arrangements for the various Scrapers, whereby the latter will 0 erate with maximum efficiency to remove t e excess pigment from the transfer material.

Referring in detail to the drawings, 1 indicates a rotary table or head supported on a suitable axle 2 carried on4 a general frame which, as shown, comprises standards 4 and 5, a top yplate 6 and a base 7. The table or head may, of course, be supported in any other position, rather than horizontally, as shown. The support for the axle 2 is best shown in Fig. 3 and comprises an upper bearing bracket 8 for a suitable bearing 9, the bracket being inserted into the top plate 6 from the bottom side thereof and secured in any suitable manner, as by means of flanges 8' on the bracket. The bottom end of the axle is support by a bracket 10 which, 'as shown, carries a radial thrust ball bearing at 11 and a vertical thrust ball bearing at 12. The bracket 10 may be secured in fixed position on the base plate 7 in any suitable manner, as by flanges 10. e

The table in the form shown in Figs. 1'to 7 has a central webbed body, including a hub 15 and machined pad surfaces, such'as 16, for the transfer material supports and other devices, to be later described. As shown, the surfaces 16 support transfer segments at 20 and 21, these being arcuate in form, presenting outer cylindrically formed surfaces 20 and 2,1', the surfaces being generated on arcs radiating from the axle 2. At the opposite glue and glycerine.

ends of the segments, there are downwardly diverging surfaces 20 and 21, respective to the segments 2O and 21. Any suitable means mayA be used tol support these segments and the material of the segments is preferably the usual transfer material, such as congealed Such material may be cast inthe form shown, that is, in arcuate segments, suitably finished to provide the surfaces 20,20, etc., or may comprise generally flat strips of suitable transfer material fastened to suitable rigid bases to cause the ma- A terial to hold its shape. The segments referably comprise cast sections or unitso suitable lengths on individual cores, such as Wood or the like, these being in the form of strips indicated at 22, there being end blocks for the strips suitably fastened thereto or integral therewith, the end blocks indicated at 23 in all fi res. The end surfaces presented by the b ocks 23 conform in general to the surfaces 20 and 21" of the respective segments.

For holding the segment units above described onto the table, there are provided flanged, arcuate attaching brackets 25 suitably bolted or otherwise secured to the machined surfaces 16 and arranged to rigidly support the transfer segment cores, as by up# `right flan es 25. The brackets may have suitable a justment and are interchangeablefer surfaces of the segments are smooth and separate pattern app ying mechanism 30 1s provided, at the rear of the table 1, as shown. This mechanism is carried on a rearwardly extending bracket 31, secured to the uprlght frame member 5 and carries a pattern r oll at 32. i The pattern roll may be of'any suitable construction and carries on its outer surface thedesired pattern; for example, it may comprise a continuous etched intaglio plate in cylindrical form. Such aA roll may be made in accordance with the patent to J. P. Henry No. 1,548,465, issued August 4, 1925 assigned lift screw, the position of which is indicated at 35, and which may be driven from the roll 32 by any suitable means. As shown, the roll is supported on a vertical shaft 36 in base and /top plate members 37 and 38 respectively, and the shaft 36 carries a gear 39 meshing with a small spur pinion 40 (see Fig. 2) to drive the screw. The base plate 37 may be adjustably mounted, as in slideways 42 on the bracket 31, (see Fig. 2) to govern the pressure between the pattern roll and the transfer segments. This adjustment may be effected and the position maintained in any suitable manner, not shown.

For scra-pingthe excess pigment from the intaglio plate on the pattern roll, there is shown a suitablescraper device, including a scraper blade 43 yieldingly mounted on a vertically slidable frame 44 carried on a suitable post 45, see Fig. 3. As shown, there is a sprmg 47 connected with an arm 48 which is in turn connected with'the scraper mounting 44 for yieldingly'urging the scraper blade into scraplng contact with the roll.

Suitable means for driving all the above described mechanism is shown in Fig. 3 and may comprise a counter shaft 50 supported in `suitable bearing brackets, such as 51 and 52, below the table and top plate. The shaft 50 may be driven in any`suitable way, as by a sprocket chain l52 connecting sprockets 53 and 54, the former being carried rigidly on the shaft 50, and the'latter being connected with the driven element of a suitable reduction gear unit 55, of known construction, -which is in turn driven, as by means of a belt 56, from a suitable electric motor 57, the reduct-ion gear unit and motor being mounted 1Q on the base plate 7 as shown. To drive the table 1, we provide a bevel gear cou le, including a driving pinion 60 on the s aft 50 and a cooperating gear 61 fast on the axle 2 of the table. To drive the pattern roll, there is provided a driving pinion 62 on the shaft 50 and a cooperating pinion 63 on a stub shaft 64 forming, in effect, a part of the shaft 36 forl the pattern roll. The shaft 50 may also reciprocate the scraper blade 43 for the pattern roll through the agency of a cam 65 on the shaft 50 coacting with a follower 66 sup rted in a suitable bracket 67 below the sha t 45, previously mentioned. The follower 66 pushes upwardly under the action of the cam on a slidin cap 68 carried freely on the lower end of t e shaft 45, and the cap may be connected as by a series of sliding pins 69 with the frame 44, which supports the lade. The blade may be returne toward the cam 65 b a suitable spring, such as shown .i in Fig. 3 at 0.

It will be seen that with the table and pattern roll thus positively driven', a suitable pigment pattern is placed on both the transfer surfaces 20 and 21 at each com lete rotation of the table, and furthermore, oth transfer segments are presented in their working position, at the front of the machine, on each rotation of the table.

The character of work shown in the machine is illustrated in detail only by way of example, and comprises a complete rectangular frame having parallel sides A and A and relatively shorter sides B4 and B'. The

interior surfaces to be decorated, as with the grain pattern of the pattern roll, are all indicated at s and are beveled in downwardly diver 'ng arrangement as shown, see Fig. 3. The inclination of the surfaces .9 ma be varied as well as the general shape o the surfaces; for example, these may be concave or convex in different frames. The frame referred to above, is for automobile Windows and there are anchor prongs or lugs at the corners, indicated conventionally at At the front of the machine (at t e right in Figs. 1, 2 and 3 there is a work carrier comprising a bar 2 pivotally supported, as on a suitable pin 73, carried by a bracket member 75 ad]ustably secured to the front face of a main bracket 74. The latter is attached to the front face o f the member 4. The bracket 74, at the end opposite the pivot pin, carries another *bracket member, 76, which has its 'i1 er surface 76 isee Fig. 7) arranged to sli a 1y carry the en 72 opposite the pivot.

To directly support and ide the work adjacent the segments 20 an 21, the bar 72 carries any suitable number of work uiding rollers 77. These may be substantial y alike, and a detail of one is illustrated in Fig. 7. As shown, the rollers have an under-cut effect at78 to clear the prongs p on the frames.

of the bar The manner in which the rollers support the work and resent the successive inner surfaces .s to tlie transfer material, is well illustrated in Fig. 3. The position of the rollers is inclined in conformity to the inclination of the inside surfaces s and these surfaces are presented substantially ilatwise to the transer material.

For controlling the printing pressure contact and for adjustment in case the sides of the frames vary in thickness, the bar 72 is mounted for movement toward and away from the axis of the table. As shown in Fig. 1, there is an adjustment device, including a short toothed rack 8O inset into the free end of the bai` 72 at the bottom thereof and meshing with a pinion 81 on a stub shaft 82, carried by the bracket member 76. The pinion is arranged to be turned by means of a chain 83 which, as shown, is yieldingly anchored to a suitable arm 84 on the machine frame by means of a tension spring 85. The chain passes over a sprocket 86 on the outer end of the shaft 82, then downwardly to a suitable treadle 87 near the base of the machine. The

sp1-in 85 will normally pull the bar 72 outward y so as to relieve pressure on the frame, whereby the operator may control the printing pre'ssure with his'foot onv the treadle, leaving his hands free to manipulate the frame, as required. To place the Work, the operator rests one edge, for example, the longer edge A as in Fig. 8, against two of the rollers 77, those nearest the pivot pin, as shown in Fig. 2; see also Fig. 8, as the segment 2() approaches the transferring position. Thereafter, by maintaining sufficient printing pressure, as by means of the treadle and associated mechanism, the segment will drive the frame along to the left (as the operator faces the machine) causing the transfer material to contact with the entire inner surface s of the side A, positioned between the rollers and the segment. The grainin operation performed in this manner is stri ingly accurate, even at the corners, and the entire surface s is fully decorated in this operation without requiring any touching up, assuming, of course, that the surface 20 is the r uired length. Actually this surface is of slightly less length than the length of the surface to be grained for the reason that the transfer material spreads slightly, due to the printing ressure, thus elongating the segment. During this operation, it is desirable to drive the frame forwardly at the start by means other v than the transfer material. For thispurpose, any suitable adjustable abutment may be provided in the foremost blocks 23; as illustrated, there are adjustable pins at 88 (screws for example) arranged to` contact with the surface .s of the frame member adjacent the oneabout to be rained. During the graining operation, t 1e frame may be supported in the inclined position shown, by any suitable arrangement, such as an overhead bar 90, having its ends depending as at 91 and then extending inwardly as at 92 for attachment to the machine frame. The frames to be grained simply slide along the bar 90 from one position to another, as will be obvious.

The succession of steps necessary, with the mechanism described, to grain a complete frame is illustrated in Figs. 8 to 11. It will be seen that as the segment 20 moves from the position shown in Fig. 8 to the position shown in Fig. 9, the inside surface of the frame element A is completely grained. The operator now lifts the frame and turns it ninety degrees, presenting the frame element B to the segment 21, as shown in Fig. 10.

Further, rotation of the table results in graining the surface s of the frame element B, this being shown as completed in Fig. 11. Next, the frame element A is rained as in the case of the element A, an finally, the

' frame element B.

Thevarious scraping arrangements for the transfer material are preferably arranged as follows. After the segments 20 and 21 pass the graining position, at the front ofthe machine, they are rotated past and in contact with a fixed scraper blade 100 on a suitable bracket arrangement 101 (see particularly Figs. 4 and 5), which scraper 100 may be carried in fixed position cn a suitable upright bar or pin 102 on the bracket. This cleans the graining surfaces 20 'and 21.

The scraper itself, after each segment has passed may also be cleaned as by an oscillatlng cleaner arm 103 having a blade 104 adapted to wipe across the front face of the blade-100. Any suitable arrangement forV operating the cleaner arm may be used; for example, we have provided cams 105 on the bottom of the table 1 designed to push outwardly on a sliding rack 106, which through a spur idler 107, drives a gear segment 108, the latter carrying the cleaner arm. Preferably the action is to clean the blade 100 on the up-stroke of the arm 103 after the pattern transfer segment has passed the blade 100 and been cleaned thereby. The rack may be returned after operation by the cam 105 in any suitable manner as by any suitable return spring, not shown. There is, of course, one cam 105 provided for each segment in order that the cleaning action of the blade 104 will occur after each scrapingl action of the fixed blade 100. By the a ove arrangement each of the se ents 20 and 21 after each graining operation thereof have their graining sur-faces 20 and 21 effectively scraped to clean off the excess pigment, before the segments again encounter the pattern roll.

It has been found that in the operation of this machine, the front or advancing edges of the segments accumulate a quantity of pigment as these edges come into contact with It is obvious that this accumulation would normally be spread onto the frame being grained. For example, in the operation illustrated in Fig. 8, such as accumulation of pigment on the surface 20 of the segment 20 would cause a smear of paint on the frame side B. To prevent this, we have provided swinging Scrapers for the front edge of the segments, as illustrated in Figs. 1, 2 and 6.

Referring particularly to Fig. 2, there are scraper arms 110, one for each segment 20 and 21, carrying respective scraper blades 111. The arms are pivotally supported on inclined pivot axes, substantially in accordance with the inclination of the surfaces 20 and 21 of the transfer segments. Suitable brackets for carrying these arms may comprise upright members 112 adjacent openings 113 in the table. The members 112 have pins 114 supporting the arms 110, and gear segments 115 rigid therewith, the latter being 1n mesh with gears or segments 116 also carried on the bracket members 112. Suitably attached to the gears 116 are depending pins 117 and these are moved to and fro by oppositely acting face cams 118 and 119 on the table. For example, the cam 118 operates on the bar 117 when the arm 110 for the segment 21 is in the position shown in Fig. 2, to throw the bar to the left, as shown in Fig. 6, thus rotating the arm 110 in a counterclockwise direction, from the dotted line position to the full line position. This, by the upward movement past the surface 21, effectively cleans the surface. The scraper 111 is, in this last mentioned operation, carried into contact with a revolving wiper head 120 mounted on a.y suitable shaft 121 carried in a bracket 122 on the table. The scraper head is revolved periodically by a successive arrangement of pins 125 (one only being shown) located on the top plate 6 to move the wiper arms 126 past the scraper blade 111 to y effectively clean the same. Suitable receptacle devices (not shown) may be provided in association with the scraper heads 120 to receive the pigment material cleaned off the scraper elements 111 by the wipers 126. After the scraper mechanism just described, for the segment 21, has been carried around to a point near the scraper 100, the cam 119 on the top plate may then, through the agency of the pin 117, return the scraper blade 111 for provision of means to scrape ofi' any pigment i material which may lie on the lowermcst surfaces of the scrapers 111 as the latter lie outa wardly from the table, and may comprise a suitable brush arrangement, illustrated in Fig. 2 at 127, thus effecting a com lete cleaning of the blade 111, which, as has een previously described, has been cleaned on its opposite surface by the scraper arms 126.

In Fig. 12 is illustrated diagrammatically a modified arrangement of mechanism or apparatus for carrying out the method above described. This differs from the previously described arrangement primarily in that the frames are not supported for rectilinearmovement while being grained. Instead there is rovided an arm'150 pivoted as at 151 about, or example, the axis of the table 1 and carrying a single pressure roller 152. With such an arrangement, the table may be continuously or intermittently driven, that is to say, the table may be stopped during the actual graining operation if desired. To grain a frame such as indicated at X, in bro-ken lines, the frame is placed between the pressure roller and the segment 20 and the arm moved automatically or by the operator, manually, in a counter-clockwise direction, as shown, carrying it to the position shown in broken lines. In doing so, one complete side of the frame is grained on its inside surface, and this operation is completed when the arm and frame assume the broken line positions. The frame is now lifted and turned at right angles so as to present one of the shorter sides of the frame to the oncoming segment 21, as before. If the machine is intermittently driven, it is preferable to locate the pigment applying devices, that is to say, the pattern roll and its associated mechanism, in such manner that the roll will be out of contact with both segments when the piece of work is in contact with either.

In Fig. 13 is illustrated still another arran'gement, particularly one in which the transfer segments are not fixed with relation7 to the table as in the previously described arran ements. In this modification, the table, mdicated at 155, is in the nature of two oppositely extending arms, one of which carries a segment 156 for graining or decorating the longer side of a frame and the other, 157, being or graining the shorter side of the same frame. In such an arrangement, the pattern applying elements, for example a roll 158, plgment pump or like device 159, and a scraper 160, may be carried in fixed position, on, for example, an overhead frame work 170, or in any other suitable manner, and an suitable arrangement may be used to intermlttently turn the table. Any convenient scraper arrangement for the transfer segments 156 and 157 may be used. Preferably there is a substantially fixed scraper 166 located in the general vicinity of the pigment applying mechanism and arranged to scrape the pattern transferring surfaces of the segments 156 and 157 just before the surface ortions encounter the pattern roll 158. buch scraper 166 may be supported in any convenient manner by the frame work of al machine, for example, the frame member 170.

The work, in case this has beveled inside surfaces, maybe supported in inclined position, as previously described, on a suitable guide bar 163. A series of pressure rollers are indicated at 164 for carrying the frames into contact with the segments. These may be adjustably and movably supported in any suitable manner. One advantage of an arrangement such as shown in Fig. 13, is that it enables the decoration of frames and the like on the inside surfaces, where these include arched effects on comparatively shortradii, such, for example, as indicated at Y in Fig. 14. In the case of a curved frame member or a frame -member having both curved and straight portions, only one pressure roll 164 would have to be used during the decorating operation on such frame member. In such case, the remaining pressure rollers could be moved out of the way, permitting the frame to swing as required, for example as suggested in Fig. 12.

It will be understood that with the arrangement shown in Fig. 13, it will be practically necessary to drive the segments 156 and 157 in such manner that they will be properly inked by the pattern roll with the desired pattern and in such manner that the advancingl edge of each segment will be properly located with respect to the pressure rollers 164, at work starting position, for example, as illustrated in Fig. 13. No driving arrangement is illustrated, but any suitable gearing mechanism may be used. For example, one or more suitably driven gear wheels, may pick up and turn both segments 156 and 157, as' required to carry out the necessary movelments thereof, with the arm member 155 temporarily held in the position shown, as well as in the reversed position (156 in position to contact with the pattern roll).
