chine constructed in accordance with the present invention.

In carrying out the present invention there are provided casings 1 supported on a pedestal 2. Each casing 1 adjacent its upper end is supplied with an inwardly projecting circumscribing lip 3 as shown best in Fig. 4. Disposed within each casing 1 is a glue pot 4 having an outwardly pro-- jecting flange 5 supported on the lip of thecasing 1, the flange 5 having-a shoulder 6'-which, coacting with the inner edge of the lip 3 holds the glue pot 4 concentric with the casing 1 thereby to define, between the glue pot and the easing,'a jacket 43. In the upper-edge of each glue pot 4 is formeda continuous circumscribing groove 7, the

outer wall 8 or which is higher than theinner wall 9 thereof. The glue pots 4 are provided with lids 10, each havinga flange 11 extended downwardly into the groove 7 Lugs 12 are carried by the flange i3,- and levers 14 are fulcrumed at '15 onthe i'liu'gs, the levers being pivoted at 16, intermedia e their ends, to ears '17 upstanding "from the lids 10. The upper ends of springs 18 are connected with the outerendsof the levers 14, the lower ends of the springs :b-eing unitedwith offset brackets 19 attached ,to the outer faces of the'casings 1. v The invention comprises a spreader denoted generally'by the numeral 20;and .including an outer casing 22 supported on a pedestal 21. Disposed within the outer casing 22, as shown hestin Fig. 2, is an inner tank 23, equipped with a flange 24 supportedon a flange 25 constituting apart of the outer casing'22, there being acket 26' betweenthe inner tank 23 13,116. the outer casing-22 Inits side wall, the -inner.tan-k 23 is provided with an opening 27,'about which extends a hood 28 which maybe formed integrally with or'connected; to the said side wall of the-inner tank. i'l heside Wallof the outer casing 22:0fthespreader is providedxwith an opening 29 coaxial with the opening 27,-butof aglarger sizethan-the opening 27.

Bearings 30 areinountedon the fiange24- of the inner tank 23,.and "inithe'bearings'30 are jzournaled shafts 31 carryinganapplying roller 32 and aspreading andrernoving roller- 32?, extended downwardly into the inner tank23 of the spreader. The shafts 3 1 carry intermeshing gear wheels '33, oneof the gear wheels33 meshing into a pinion 34 fixed to a drive shaft journaled in a 1 hanger 36 carried by the outer casing 22. Any suitable means may be provided for' rotating the shaft 35, a pulley 37 and a belt 38 being shown in the present instance.

Mounted on the flange 24 of the inner tank 23 and disposed on opposite sides of the bearings 30 are brackets 39 to which up standing arm 40 are pivoted as shown at 41.1 Screws 42 are carried byv the brackets 39 and pass loosely throughthe arms 40.- Springs :43 surround the screws 42, the inner ends of the springs 43 abutting against the arms 40, and the outer ends of the springs abutting against hand wheels 44 which are threaded "onto the screws 42. Shafts 69 arejournaled in the arms 40, one of the shafts 69 carrying a doctor roller 45 driven byv contact with the roller 32, and the other of the shafts 69 carrying a wiping roller 45 driven by contact with the roller 32*. v y

The numeral 46- denotes cold water pipeswhich' commu 'iicateas shown at 47 withthe jackets48 between the glue pots 4 and the casings 1. Interposed in the pipes 46 are' handvalves 49. Each. pipe 46 -has an up ,wardly prolonged ,branch'50 extended as shown at 51into the. jacket 48 and terminating in anfexposed cock =52located.extcriorly; of the casing 1. Leading from the parts 47' ofthe cold water intake pipes are drainage branches 53 'in which are interposed hand valves 54. -The drainage branches 53 communicate with drain pipes 55 which are up wardly and laterallyextended as shown 56, the part's56 of the pipe 55 ,communicating with ithe jackets '48 between the .glue

pots 4and the casings 1.

The numeral 57 marks a steamfsupply pipe which is prolonged horizontally as shown at 58 infront of'the casings 1, the

part 58 of the steam pipe having depending branches- 59avl1icl1 communicate with the jackets 48. .I'nterpo'sed in the branches 59 ofthe steam pipe are valves 60, and condensers '61 are "also interposed in the branches 59! The steam pipe 57 has'a branch 62 carrying a hand valve 63. The branch 62opens through the outer tank23 of the spreader and communicates with the jacket 26; A pipe 200 leads from the jacket26 to one of the drain pipes Glueconveying pipes 64 are provided, the same passing through the jackets 48 and communicating with theglue pots 4 as shown in Fig. 4. These glue pipes 64 are 1 equipped with hand valves 65. The lower ends of the pipes 64 merge into api pe 640 whichv enters the opening 27 in the inner tank 20 of the spreader, asshownin- Fig.2,

' the discharge end of the glue pipe 640 open ing within the contour of the hood 28. The pipe 640 is surrounded, adjacent the spreader 20, by a tubular jacket 66, the inner end of 'which is mounted in the opening 29 of the outer casing 22 of the spreader. The outer end ofthe jacket 66 is connected with the pipes 640 adjacent the spreader 20 suming that the jackets 48 are empty of hotv water, the valve 49 are opened, and the valves 54 are closed. Cold water then passes by way of the pipes 46 and their-branches 47 into the jackets 48 and accumulates therein until the jackets are substantially full, the

excess cold Water passing away throughthe pipes 56 into the drain pipes 55' The glue is then mixed properly in the cold glue pots 4, and if the valves 49 are closed, the valves 54 being opened, the cold water in the jack: ets 48 willflow by. way of the

pipes

47 and 53 into the drain pipes The valves 54 then are closed, and the apparatus is insuch a condition that the glue can be heated up.

In order to heat the glue, the valves 60 are opened, and thensteam traverses the pipe 57, the pipe 58yand lts branches 59. The steam,- passing through the condensers 61, is turned into hot. waiter'which enters the jackets 48, the temperature of the Water in the jackets 48 being determined by thermometers68carried on the exterior oiithe casings 1., The overfiowliot Water in the jackets 48 passes by way' of the. pipes .56

into the drain pipes 55. The temperature of the water in the jackets 48 may be regulated a Y by opening the valves 49, so as to admit a supply ofcold water'from the pipes 46 into the jackets by way of the pipes 47.

The valves 65 areset to permit the desired flow of glue from the glue pots 4 through the pipes .64 and 640' into the inner tanks 23 of the glue spreaders 20. The glue pots 4 are hermetically sealed byj the lids 1 0, and

consequently, the glue will flow through the lower ends of the pipes 64' and 640 into the inner tank 23 of thespreader, only when the glue in the inner tank 231mg been depleted enough'so that air can enterthe pipe 640 through the hood 28. This operation takes place automatically, to inaintaiin'practical1y, a constant level of glue in the inner tank 23'of the spreader, and after the valve 65 have been set, they needbe m-aniplated only for the purpose of regulating the amount of glue delivered. i V

- The steam within the glue pots 4 accumulates on the lids 10 and runs downwardly and outwardly along. the underfsurfaces of the lids, acrossthe upper edge ofthe'relatively low inner wall 9, into the-grooves 7.-

When this water of condensation haSae-f cumulated sufficiently in the grooves 7 the water flows over the upper edge of the wall 9, and passes back into the glue pot 4. The flanges 11 on the lids 10 dip into the water seal in the grooves 7 and thus the glue pots are sealed hermetically. The springs 18, react on the levers 14, to hold the lids 10 down on the glue pots 4, it being possible to detach the upper ends of the springs from the levers 1 1, or to detach the lower ends of the springs from the brackets 19 when it is desired to swing the lids 10 to open positions, as takes place when the supply of glue in the pots 1 is to be renewed.

The branch 50 and its extension 51, together with the cook 52, constitute a means whereby a supply of. hot water may be secured at any time. These parts have nothing to do with the operation of the machine, so far as the melting or manipulation of the glue is concerned.

WV'hen the drive shaft 35 is rotated by means of the pulley 37 and the belt 38 or their mechanical equivalents, the pinion 34 on the drive shaft 35, meshing into one of the gear wheels 33, drives said gear wheel, and the said gear Wheel drives the other gear wheel, the shafts 31 being rotated, and the applying roller 32 and the spreading and removing roller 32 being rotated in the direction of the arrows in Fig. 1. A board or like object, which is to be glued, is pushed across the tops of the

rollers

32 and 32*,

in the direction of the arrow A of Fig. 1.

The roller 32: applies the glue to the board and the roller 32 which rotates in an opposite direction to the roller 32, spreads the glue evenly over the board, and takes off the excess glue. By rotating the hand wheels tt, the pressure of the roller 45 on the roller 32, and the pressure of the roller 45 on the roller 32 may be adjusted, the roller 45 bearing on the roller 32 with a stronger pressure than that exerted by the roller 45 on the roller 32. The roller 45 therefore, wipes off the excess glue on the roller 32 the roller 32 being, essentially, a glue spreading roller, whereas the roller 32 is a glue applying roller.

Steam from the pipe-62 is delivered into the jacket 26 of the spreader for heating purposes. The steam leaves the jacket 26 by thebranch 201, the pipe 200 and one Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

to the spreader. Because the pipe 200 opens at one end into the jacket 26 of the spreader in spaced relation to the branch 201 which connects to the part66, there is a through circulation of steam in the jacket 26 of the spreader, and all of the steam does not make a short-cut to thepipe 200 by the branch 201.

Having thus described the invention, what is claimed is 1. In a device of the class described, a glue pot; a spreader including an outer casing and an inner tank defining a space between the casing and the tank, the casing having a sidewall, and the tank having a side wall and a bottom; means for heating the contents of said space; a glue pipe leading from the pot to the tank and extended across said space and ithrough both side walls; a tubular jacket surrounding a portion of the glue pipe exterior to the casing and having one end mounted in the side wall of the tank and in communication with said space; means for closing the outer end of the jacket about the pipe; and an arched hood carried by the side wall and the bottom I in the hood.

2. In a device of the class described, a glue pot having a jacket; a spreader having a jacket; a glue pipe leading from the pot to the spreader; a jacket about the glue pipe and communicating with the jacket of the spreader; means for supplying steam to the jacket of the spreader; means for supplying steam to the jacket of the glue pot; means for supplying cold water to the acket of the glue pot; a drain pipe leading from the jacket of the glue pot; and a steam outlet pipe leading from the jacket of the spreader to the drain pipe and having a branch communicating with the jacket of the glue pipe.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
