, The invention consists in the peculiar fea- 5o tures of construction andnovel combinations of parts in machinery for the manufacture of sticky fly paper, as hereinafter moreparticularly ydescribed and claimed. f
In the annexed drawings illustrating the invention-Figure 1 is a sectional side eleva- 55 tion of one end of our improved machine for making sticky fly paper. Fig. 2 is a side elevation'of the other end of said machine. Fig.
3 represents a portion of a strip of paper after it has been coated and perforated but be- 6o fore it is folded.

Fig. 6 is a side elevation of the cooling trough 01- water jacket for controlling the temperature of' the paper after' it has been coated. Figs-7, S and 9 are |vertical transverse sec- 75 tions of vthe cooling trough and contained papel-strip on the lilies 7,- 8' and i), respectively,
of Figs. l and 2. Fig. 1() isa view of a grooved roller. A
`Referring t0 Fig. 1, the numeral 1 desig- 8c natos the frame of the machine near one end of' which is suitably supported a tank 2y having apartition dividing it into parallel compartments 3 and 4, Fig. 4, adapted to contain a glutinous oradhesive coating material of any suitable nature such as is commonly used in the manufacture of sticky [ly paper.
In manufacturing a sticky fiy paper having a field of less adhesive substance surrounded by a margin or border of more adhesive maoo terial, as described in the before described Letters Patent No. 470,087 dated May 31, 1892, we' place in the tank compartment 3 the less adhesive substance for composing the field and in the tank compartment 4 we place the 95 'more adhesive or thicker material for coni-A posing the slightly,1 raised and adhering border of the fiy paper. At a suitable point in theI tank 2 is journaled a transversely arranged rotary shaft 5 which is extended tro througnboth compartments ofthe tank as shown in Fig. 4.- Securedy to this shaft 5,
faces 10, Fig. 5, disposed at suitable intervals` to prevent contact of the drum, at those points, with the moving strip of papel-and so provide for leaving uncoated the spaces 11, Fig. 3, be-
tween adjacent sections of the fly paper. As
in some cases the gaps 9 are objectionable by causinga churning action of the drum 6 in the adhesive material, and the mixture of air therewith, we Vprefer to Hatten or slightly reduce the diameter ofthe drum at the required' points, as 10, Fig. 5, to 4correspond with the uncoated intervals to be left on the strip of fly paper. These flattened or reduced portions 10 need not be recessed into the body of the drum, as the shoulders thus produced would be objectionable, but as indicated by dottedlines in Fig. 5, said flattened portions 10 of the drum periphery may each corre- Spond to segments of a much larger circle than is formed by the main bodyof the drum. Secured to the shaft 5, in position to be revolved in the tank compartment. 4, is a drum 12 which comprises annular ribs 13 connected at suitable intervals by cross-bars or trans-- verse ribs 14, Fig. 4; said annular and transI verse ribs being so arranged as to be capable.
of taking up the sticky material in the tank compartment 4 and applying it to the paper strip 7 in such-manner as to form on one side of the median line of said paper a rectangular border 15, asshown in Fig. 3. The drum 12 may also carry a star or cross shaped projection 16 in position to apply a correspondingly shaped surface 17,` Fig. 3 of thickcned adhesive material to the paper 7 in the center of the border 15formed by the annular and transversely ribbed portions of said drum. It will be understood that when the paper strip 7 is foldedalong its median line the series of fields 8 will each register with a corresponding border 15 and cross or star shaped center piece 17 so that by mutual transfer of the sticky material on opposite sides of the median line the said paper will be provided with a double series of fields 8 each provided with a surrounding border 15 and inclosing abenter 17, the-said fields being less sticky than their borders. Both drums 6 and -12 are preferably made with solid ends so that there is no possibility of the sticky substance entering the inside of the field drum 6 nor through either head of the border drum 12.
'lhe continuous paper strip 7T to be coated I with adhesive material in the manner -above described, is supported, in the form of aroll, on a rcel 18, Fig. l, from which it is gradually drawn olf by feed rollers 19 and 2l) that can be driven in any convenient or suitable manner. The lower feed roller 20 is journaled in suitable bea-rings provided in the frame of the machine while the upper feed roller 19 is journaled at each end in ayoke 2l having its lower end pi frotally attached to a lever 22 that is fulcr'umed at 23 to oneside of the machine frame. Each yoke 2l surrounds one end of the lower feed roller 20 and is supported by a separate lever 22. On the short arm ofV each lever 22 is a weight 2t by which the levers are counterpoised. Thelong arm of each lever 22 isconnccted by a link 25 to alever 26 fulerumed at 27 to the lower part of the machine frame. From the feed rollers 19 and 20 the paper strip 7 .passes beneath a vertically movable sag roller 28 and between friction rollers 29 to the auxiliary feed rollers 30 which may be driven by any suitable means. It is essential that asthe paper strip travels toward the coating apparatus it shall be quite flexible in order to insure its perfect lateral guidance. This .is accomplished by the action of thesag roller 28 operating upon the compound system of levers 26, 25, 22 to automatically control the tension and feed of the paper'and thereby govern or equalize its fiexiblity. Ordinarily the weight of the sag roller 28 resting in the 'loop of the paper strip between the feed rollers 19, 20, and guide rollers 29 will be sulficiefnt to give the required tension to the paper and cause it 5to be fed evenly.` Should the feed rollers 19 and 20 draw the paperfrom the reel faster than the auxiliary feed rollers 30 take it up, the sag roller 28 will drop on to and depress the long arms of the leve'rs 426 which through the links 25 will draw down the long arms of the levers 22 and thereby cause the yokes 21 to raise the upper feed roller 19 from its engagement with the lower feed roller 20; thus stopping the feed from the reel until the rollers 30 catch up the slack and lift the sag roller 28, when the upper feed roller 19 will drop on to the lower feed roller 2O and cause the feed of paper from the reel 18 'tobe resumed. It will'A thus be seen that by means of this mechanism a perfectly automatic feed and tension of the paper strip are maintained.
If desired the frame of the machine may be provided with a vertical slotted gnideway 31 for the ends of the sag roller.
IIO
From the automatic feed and tension mechanisln above'described the paper strip 7 is carried around a roller 32 that is supported in suitablebearings in the upper part of the machine frame immediately above the coating drums. formed in the central portion of the roller 32 is arranged a perforating wheel 34 mounted on a shaft that is supported in the same bearings with said roller. On the shaft of the roller is secured a band pulley 35 through which said roller is rotated by means of belting 36 from a countershaft 37, as shown. The shaft of the roller 32 also carries Va spur gear ing power to the coating devices. 'By means of an eccentric lever mechanism-(not shown) similar to that employed in throwing an engine lathe ont of gear, the machine may be stopped and started at will.
In passing between the roller 32 and the coating drums' 6 and' 12 the strip of paper is supplied with coating material to form the fields 8, borders and center pieces 17, disposed in the manner shown in Fig. 3,.as already' described. The coated paper strip 7 theupasses over the roller 32 and beneath the perforating wheel 34 thereby receiving a longitudinal series of perforations 4l, Fig. 3, in its median line. The perforating wheel 34 operates in line with the annular groove 33 formed in the roller 32 and may be of any suitable construction adapted' to produce the required perforations in the paper strip. n
From theroller 32 and perforating wheel 34 the coated and perforatedstrip of paper is passed into the shallow and comparatively flat end of aconcaved cooling trough 42, Figs. 1, 2, 6, 7,8and 9. This coolingtrough is pref erably constructed with double metal walls in the form of a water jacket that is divided into two compartments 43 and 44 by means of alongitudinal partition 45 at the bottom, as shown in Figs. 7,8'and 9.l By this means the water in the two compartments 43 and 44 can be maintained at different temperatures acf cording to the different degrees of adhesiveness or-consistency required in the coatingson the two sides of thevpaper strip. Each compartment of the water jacket may be provided with an inlet pipe 46, Fig. 6, at one end andan outlet pipe 47 at the other end by which a continuous flow of water, at any temperature, can be obtained. It will be observed l. that the water jacket or cooling trough 42 is comparatively shallow and wide at its outlet end, as shown in Figs. 1, 6 and 7, and that it is gradually increased in depth and decreased in width toward its inlet end, as shown in Figs. 2, 6, 8 and 9,*thus causing the opposite edges of the paper strip to approach each other as said strip is carried forward through the trough.
To facilitate the cooling of the coated paper strip we may direct a current ofair onto its coated surface 'from a pipe 48 through which the air is forced bya rotary fan 49 which may be `driven by belting Ofrom a`pulleyon the countershaft 37, as shown in Fig. 1. I As it is desirable that the sticky substance lshould be applied to the paper at a high temperature, by'which the proper degree of con,- sistencywill be maintained to insure an even distribution of Asaid substance, it becomes necessary to cool the substances to a certain extent before the opposite edges of the coated paper strip are folded together. The tank compartments 3 andI 4 are supplied w'th sticky substance i .'om a supply A tank, or supply tanks, 5l which maybe heated by steam pipes, (not shown,) that can be also l' arranged to heat the tanks 3 and 4, in any Well known manner. Thermometers may be placed in the tanks 3 and 4 to indicate the temperature of their contents, so that by any suitable means for controlling the heating of said-tanks the sticky substance-in each tank compartment can be maintained at the proper consistency. The supply tank 51 may communicate with each compartment of the coating tank 2 through a pipe 52 having a hand valve 53 by which the supply ofsticky material can be entirely cut 0E at will. When the apparatus is in operation this hand valve 53 is to'be opened. The height of the coating material in the tank compartments 3 and 4 may be automatically controlled by means of a float 54 immersed in the contents of each tank and connected by a rod 55 to one end of a' lever 56 that is fulcrumed to a stud or standard 57 supported by the supply tank. To the other end of the lever 56 is attached a depending rod 58 which carries a conical ended valve 59 adapted to control the upturned funnel shaped end 60 of the connecting pipe 52 through which the sticky7 material is conducted from the supply tank to the coating'` tank; It will be seen that as the material is supplied to the coating tank 2 the float 54 will riseuntil the descent of the valve 59 closes lfloat 54 and valve 59 canbe readily controlled so as to maintain any required depth ofmal terial in the coatig tank. lBy thus regulating the supply of material, providing for maintai n-ing the stickycoatin g substances at proper relatively regulated temperatures, applyingl said substances while hot to a moving strip 'the inlet end of the pipe 52; and that as the IOO ofpaper and properly cooling the strip of coated paper before its opppsite edges are folded together alarge economy of time and labor is eected and the manufactured article can be turned outfrom the machine with great rapidity in readiness for the trade;
It will be seen that owing to the construction of the cooling trough 42 by which it is graduallyincreased in depth and diminished in width the current of air issuing from the .Y
pipe .48 onto thecoated surface of the moving strip of paper will be toa large .extent confined between the opposite sides of the trough and-will thus be caused to exert a cooling effect on the coatedl surface of the paper throughout the length of the trough.
In passingthrough the trough 42 between its gradually approaching sides the opposite vertically projecting edges of the paper strip 7 are brought toward each other a`ud the said strip of paper has imparted toit a fold on the central line of perforations 41,.Fig. 3. From the trough 42 the partly folded lower or cenf trai porticp of vthe paper strip passes between two creasing plates G2one of which is arranged on each side of the lineof fold to insure the close folding of the paper directly in its line of perforations. 'llle folded paper stri p thell passes between two vertical rollers 63, preferably colnposed'of rubber, by which the opposite sides of the folded paper strips are lnatted together, thereby causing the fields 8 on o ne side alld the thickened borders 15 of the other side to be mutually transferred so tllat, when opened, both sides of the coated papel' will be alike. From the lllatting or transferring rollers 63 the folded paper strip is drawn between tellsion or feed rollers G4 having enlarged end portions 65 for the purpose of tightly holding the two marginal edges of the papel', and thereby feeding it along between two vertical plates or stationary cutters 66 to a revolving cut olf knife 67 by which the paper strip is severed at proper intervals, through its uncoated transverse margins or spaces 11, Fig. 3 into doubled sheets suitable for the trade. The revolving knife or cutter 67 is carried by a rotary head 68 to which it may be attached by means of set screws 69 so that it can be adjusted to take up wear. If desired the two sets of rollers 63 and 64 may be provided with tightening or adjusting screws, not showll, to enable them to be so adjusted as to cause the transfer rollers 63 to properly mat together the opposite sides or edges of the paper while it is carried forward by the feed rollers G1 to the cutting mechanism (S6 and 67 as above described.
In order to provide for operating the feed or tension rollers 61 and revolving cutter 67, the shaft of the coatingdrums (5 and 12 may be provided with a bevel gear 70, Fig. 4, meshing with a bevel pinion 71 on h.one end of a line shaft 72 supported in suitable bearings 73 and extended longitudinally with the frame of the machine. The shaft 72 carries a bevel pinion 74, Fig. 2, that meshes with a bevel gear 75 on a transverse shaft 76 that is con-` nected by bevel gearing, not shown, with the feed rollers 64,Whereby said rollers are actuated. The transfer rollers 63 are'actuated by frictional contact of'A the moving paper strip and, therefore, require no gears. One of the feed rollers 64 is geared through an intermediate gear 77 to a spur gear 78 on the lower end of a vel-tical sh-aft 79 to which the cutter head 68 is secured, thus providing for actuating tlle rotary cut off knife. If desired the shaft 79 may be provided with a crank-arm 80 for attachment of a lever81, Fig. 2, through which any suitable counting or register and alarm mechanism, not shown, may be actuated for the purpose of indicating the amount of work accomplished by the machine.
It will be observed that as Vthe two coating drulns 6 and 1'2 are rigidly secured to the same shaft and thereby caused to rotate together thegelds 8 and borders 15 will be so applied Yto the paper that when the paper stripV is folded longitudinally, as described, 'there will be an accurate register of the saidfields and borders and a mutual transfer'of the salne from one side of the paper to the other, so that botll sides will be alike, each comprising a series of sticky fields Surrounded by lborders of somewhat greater adllesiveness and eacll inclosing, if desired, a cross or star sllaped center piece 17 also of greater adhesiven ess or consistency than the field. It may also be observed that by actuating the rollers 64. and rotary cut off knife 67 froln the shaft 5 of the coatingdrums 6 andl2 the machine will be accurately timed so that the cutting of the sheets will be assured to occur in the uncoated spaces 11, Fig. 3, left by the gaps 9 or flat portions l0 of thecoatingdrums. These features of the machine are of great ilnportance in facilitating the rapid and economical manufacture of sticky ily paper from asingle continuous strip of paper, thereby insuring `more perfect work tllan can be accomplished by using 'two separately coated sheets or strips.
For the purpose of governing the thickness of the coating to be applied to the papel' and to illsure clcall margins between the several slleets or prints we may employ a longitudinal scl'apcr S2, Fig. 5 attached to arnls 83 by means of set screws Si and jam nuts and arranged to extend the entire length of the coating drulll 6 by which the fields S are applied to the papel' strip. The points of the set screws Sl extend illto annular grooves S6 that are formed in the drum 6 near its ends, alld by properly manipulating these screws and nuts the scraper can be readily adjusted S0 as to scrape all surplus of coating material from the dlulnand tllereby regulate the tllickness of the 'coating to be applied to the paper. At the flattened sections 10 of the drum 6, Fig. 5, the grooves 86 are deepened so that the scraper 82 is allowed to drop at those points and take all the coating thus insuring clean margins between the prints or several sections of the coated paper strip. Any suitable springs 87 lnay be arranged to bear ou the arms 83 in such a manner as to hold the set screws firmly in contact with the bottoms of the grooves 86 and thus cause the scraper to act properly and uniformly. The springs 87 and arlns 83 may be attaclled to suitable4 supports by means of set screws 88 that can be adjusted to regulate the tension of said springs, as required.
The bearings of the roller,32 and perforating Wheel 34 may be arranged in a vertically movable bo'x or frame 89, Fig. 1 having a lever 90 attachedthereto by which said roller and perforating wheel can be liftedA away from the coating drum`6 whenever the operator sees that the paper strip is torn or mutilated or has holes therein tlrough which thecoating material on the drum would pass through onto the roller 32 and thence to the outside of the paper strip. By thus arranging the roller 32 so that it can belifted away `from the drum 6, Wllen required, theoutside of the paper strip can be kept clean and provquired, tear the salne apart along the lille of p erforatious 41, Fig. 3, wllen each half or se'ction can be employed separately in the well known manner.
