Application filed. November 23, 1927. Serial-No. 235,306.

This invention relates to improvements in book-making machines, and more particularly to the filler in cooperative relation with the ad hesively applied cover, one object of the in-. vention being the provision of a palette'of A further object of this invention is the" provision of a sectional palette for book-making machines in which yi'eldingly mounted bars or extensions are provided, two to each section, and so constructed and arranged as to insure the feeding of'the fillers toa flexible I covering' sheet to provide stifi or'flexible backs for books, said sections being so constructed and arranged as to render the pal, ctteadjustable-both longitudinally and transversely to accommodate fillers and covers of different areas. I D i I In the accompanying drawings I the carrying arm being shown in section.

Figures 10 and 11 are views ofpneumatic means'for projecting the bars and forming a yielding pneumatic cushion therefor.

Referring to the drawings,-the numeral 10' designates a laterally swinging arm of the book-making machine which has the flanged head 11 for supporting the palette P. F and F indicate the filler, Othe flexible cover sheet, and L the lining strip.

The palette consists primarily of four members 13, 14, and 16, respectively, each one of which is substantially'identical in conpalette which is used in placing the" Yatlve positions and in pairs.

Figure 1 is a top plan view of the palette,

i in turn, clamp the grooved portion .11 of the and 30, to the I respective bars 26 and 27. Thus, in this way, 1 the four sections are connected by the i restruction, so the description of one will suffice for all, In order to connectthe respective sections 13 and 14-and 15 and 16 for longi- I tudinal adjustment, I employ'the two bars pair, the lower edge I l7 and 18, one to each of thebars being provided with a rib 19 for sliding in the groove 20 of the respective sec tions so that the bolt 21 with its nut 22 may adjust-ably attach the sections in thei 'relprovided with a hose-receiving projection 23 and with a rubber vacuum cup as 24, so that Ea'ch section is I the filler and lining strip may be suctionally I held in'place during the movement from the;

pile to and upon the cover sheet C. These nozzles 23 areconnected by a. flexible hose 25to the main carryinghead 10 in the usual v In. order to'p rovide a lateral or transverse;

adjusting. means for the respective sections of the palette, the two bars .26 and 27 are connected by means of screw bolts 28 and 2,8- to the bar 18, while the free ends rest upon the i I bar 17 and'are connected thereto inadju'stable relation by means of the bolts 31 wh member 10, as indicated at 29 spective members 17 and 18 and 26 and 27 to be held in fixed adjusted relation.

Each section has projecting 34. The-lug 33- is provided with an opening v35 therethrough, which is alined with the opening 36 of the .lug 34, while the lug 32 I I I from the. up per surface thereof the three lugs 32, 33 and and is stopped in its outward movement by means of the screworbolt39, the spring-40- being mounted upon the pinandexertin'g a I pressure on the outer face of thelugx33 and cooperating with the spring v42. mountedupon the sliding pin 41 to hold the presser bar 43 outwardly and? awayfrom'the outer 1 face of its respectivesection. The lugs 33 and 34 are provided with the openings '44 I and 45 which are below and'at right angles to the respective openings 35 and. 36 and;

have 'slidably mounted therein the pins '46 and 47 which are attached to and carry the short presser bar 48, a slotted limiting lug.-

49 being carried'by the bar and cooperating .cover C away from with the bolt 50 to slidingly attach it to the section 13. A sprin 46 is mounted upon each of the pins 46 and 47 to holdthe presser bar 48 outwardly and away from its section; The vertical ribs 51 and 52 are formed in-- tegral with and in spaced relation upon the V W hen the sections are a j to take the lining strip or back lining section L or are in the position as shown in Figure 1, the space between the respective sections is filled in by the lining strip lifting sections 53 and 54, the same being connected to the under Each section 5354 is also provided with the suction device .18, which, when in use, 1s

- clip 56 being composed of side of the bars'17 and 18, respectively, by means of a screw 55, one to each section.

connected to the usual flexible hose connections 25, and thus permits the present palette to simultaneously elevate two fillers F and F and one lining strip'L.

Inorder that two adjoining bars 43, or two adjoining bars 48 may be made continuous,

respectively,there is provided a spring clip or connector 56 which is adapted to be placed either over the upper edges of alined presser barsor the low r edges as the case may be and the occasion warrant, the said spring metal bent upon itself and havinga tendency to gripthe respective bars upon which it is attached and spanning the same, as

pressed bed illustrated in Figure 5, so as to make 'a' continuous bar so there can be no space between the ends thereof that mightpermita pucker or inward fold upon the filler F during the movement of the bars inwardlv.

When the present device is in use it is similar to the palettes shown in the various patents toJacobs, and that to Satenstein, No. a

springs which yieldingly hold the presserbar 1,328,767 but briefly stated, it is as follows:

i The flexible cover C is placed upon a-spring- (not shown) with the usual edgeforming members 60, onlv one set of which is here shown, in a positionto permitthe pal- V ette with the respective presser bars 43 and 48 fully extended to pass therebetween and place the filler F upon the cover C. When the filler is below the members'60, the mem bers 60 are moved inwardly, engaging the upturned edges of the cover C and pushing them over and upon the upper side of the filler F, and at the same time pushing the respective presser bars againstthe action of the springs, as is the usualpractice, or in a sufficient distance to permit the edge-forming portions 60 to press the Lip-turned edge downwardly upon the filler F and its inner edge thereof free from'the outer edges of the rea sheet of flexible spective presser bars, and then the edge-forming member upon the remaining two sides are moved in to complete the operation.

It is evident from the foregoin description that-with a palette made accorc ing to the present invention a book-making machineis adaptable for use upon the varioussized book covers with flexible or stiff fillers and lining strips for the back, and also carrying the lining strip simultaneously with the filler so that when the present palette has completed its operation with the lateralplungers of the book-making machine, the complete bookback, including two fillers with or i ithout the back lining strip, is completed, and is held during the forming operation in a flat nonwrinkled position so as to'insure'a complete and neat article. i

In practice I have found it desirable to provide some means for preventing the puckering ofthe cover at the corners and at the same time to improve thefolded and finished article at this point, and to this end I have em: ployed the construction as illustrated in Figure 7 and in the methods as illustrated in Figures 8 and 9. The bars 43 each have mounted upon one end thereof, the end nearest the corproper straight-line movement between the parts. The spring'68 is'disposed and mounted to hold the extension outwardly with, its right-angledhead 69 in the desired position forfcooperating withthe overlapped end of the presser bar- 48, as illustratedin the steps in Figures 8 and 9, Figure 8 showing the device in the position it assumes at the initial movement of the'palette down between'the folding plungers, and Figure 9 when the re-' spective bars 43 and 48 are brought into coopcrating position, the extension 65 clearly clos ing the gap at the corner;

In order "to provide an alternate .for the outwardly,- I have shown in'Figure 10 a vacuum or "suction means, the plunger 69 in this instance being operated upon by afsuction or vacuum to hold the presser bar 43 yieldingly outwardly As shown in Figure 11, pressure is employed instead of suction, and inthis instance, the'plunger 7 0 is held outwardly from the pressure at the rear thereof;
