Specification of Letters Patent.
Patented Febo 21, 1911.
Application filed September 15, 1909. .Serial No. 517,902.
To all whom it may concern:
Be it known that I, CHARLES WARWICK,
citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented anew and useful Shingle-Drying Machine, of Which the following is a specification.
This invention relates to a machine for drying shingles and is designed to effect that object by the exposure of the individual shingles to the drying agency as .they come from the saw and before the are bundled.
The present method'of drying shingles in bundles in a steam heated kiln is inefiicient in that it takes a considerable time for the heat to penetrate and the moisture to escape from a tightly bound bundle of shingles and the inner shingles are frequently insufficiently dried. The process is also costly owing to the large number of shingles that is required-to stock the kiln for that length of time. There is also the risk of fire to which such drying kilns are very liable and which may destroy a large number of shingles and an expensive kiln.
My efiort has'therefore been directed to the provision of a means whereby the individual shingles as they come from the saw are exposed to a dry heat that will effectually evaporate the moisture from them. This object I attain by passing the shingles onan endless conveyer band or succession of such slowly through a chamber exposed to the dry heat of a furnace flue, means being provided to withdraw from the chaniber the evaporate moisture from the. drying shingles; care being taken to so support the shingles onthe band that both sides of them are exposed to the action of the heat and to so arrange the conveyer bands, Where more than one is used that in the earlier stages the heat is not sufliciently intense or sufficiently dry to warp the shingles and that they, are turned when passing from one band onto the other. k
The invention also comprises certain subsidiary features in the construction of the conveyer band or. chain to prevent the feather edges of the shingles from catching in it .and to a means for rectifying the shingles on the bands.
The invention is particularly described in the following specification, reference being made to the drawings with which it is accompanied, in which:
Figure 1 is a vertical longitudinalsection through the drying chamber and its fines;
Fig. 2, a sectional plan on the line A A in ported in the extended length between the end reels.
In these drawings 2 represents an elongated chamber preferably of thin sheet 'metal which chamber is exposed to dry heat by a flue 3 from a furnace, the flue 3 passing,'in this particular machine, from the center of one side of the chamber 2 along the bottom of it and along one side to one end, along the other half of the bottom and the other side to the other end and back tofan exit 1 adjacent to the point of en'- trance whence the flue is connected to a chimney or Smokestack. Partitions 5 and 6 separate this flue at the mid-length and along the bottom. This arrangement of the fiue 3 is not, however, in any way essential to the invention as the same may be modified to suit the requirements. Within this flue- I heated chamber 2 a series of endless conveyer bands 10 are carried on rotatably mountedreels 11 toward each end of the chamber by which reels at one or both ends the conveyer bands are driven at a uniform slow speed in opposite directions by sprocketwheels 12 external to the chamber or by other suitable means. These conveyer bands 10 are so arranged in relation to one another that the oneabove delivers onto the one beneath at a sufiicient distance from the end to enable a shingle falling off one to be received by the other, and a guard 13 secured to and downwardly projecting and angled outward from the end of the chamber 2 prevents the falling shingle from passing down behind the reel 11. angled sides 14' designed to center the shingle on the band which angled sides are carried forward. from the guard as at 15.
This guard 13 has a over.
' wheels or rollers 19 on each: side to run on the chain links so that the bars 26 will en'- v at a hopper 27'at one end of the top which v theoverbalancing end will fall upon the shingle under the band above until the after and in the fall this end is again centered on from one band onto the one beneath shall in that movement be turned over, the upper side of "each band is a greater distance at the receiving end from the under side of the one above it than at the delivery end, so as, to afford more room for the shingles to turn Diificult has-been experienced in design ing a ban that will have the required flex1-' bility' around the end reels, that will sustain the shingles off the general surface of the band that both ends may be exposed to the drying agency, that will not offer any interstices or apertures in which the feather edges of the shingles are likely to catch,
and that is withal simple and cheap to manufacture. With these objects in view I preferably construct the band as a chain of links 16 each formed of thin sheet metal of the required width of the conveyer, one end '17 P being formed cylindrica'lly to rece ve a shaft 18-the ends of which project beyond the width of the band to receive small flanged longitudinal tracks 20 and support the hand or chain between its ends. The other end 21 of each link is oppositely bent to encircle the smaller end 17 as shown in Figs; 6 and 7.-
The driving and carryin reels 11 may each be constructed of two anges 25 across between which are secured bars 26 the pitch between which corresponds with the pitch of gage the bent ends .of the chain links and effect the driving of the chain.
The shingles are delivered onto the band hopper is provided with sloped sides that will rectify and center the shin les on the width of the upper band 10, an the dried shingles are delivered at the opposite lower end through an aperture 28 onto a chute 29.
The moist'vapor given ofl from the dry-- ing shingles is conducted from the chamber 2 through a passage 30' which may be connected with'a chimney to induce a draft.
In use the shingles are fed through the hopper 27 andare centered on the upper band 10 traveling slowly in the direction of 'thearrow toward the other end of the chamber 2: As they overbalance at that end band 10 beneath, traveling in the opposite direction, being centered in its fall by the angled sides 14L and 15 of the guard, The band beneath traveling in the opposite direction will carry the overbalanced end of the end of'the shingle falls over in which movement the original under side is uppermost the band. This reversal is effected at each conveyance on a travelinfi as new and desireto be end of the machine as the shingles are transferred from one band to the other until they reach the exit 28 and are delivered 'onto the chute 29 to be bundled. The speed of the conveyer band is so regulated'that the time I of exposure to thetemperatu're. of the cham- -ber will eflectuallydry the shingles before they are delivered from the machine.
.It will be noted that the upper part of the chamber 2 is. not directly exposed to the heat I of the flue. and the shingles on the upper band are therefore only exposed to the hot air and moist vapors rising from the lower part. vThis insures that the earlier process of drying is not conducted too rapidly, and toward-the lower part of the chamberwhere a greater heat is necessary to efi'ect the final rying the shingles are exposed to a greater and a drier heat. The heat admitted to the flues 3 may be Eontrolled by a damper 31 in the entering ue. j
Although I prefer the arran' ement here revealed of superposed conveyer ands delivering the; shingles one upon the other, as such an arran ement is I believe a more favorable one and will economize space I do not desire-to be confined to it as I regard the essential feature of my inventionto be, the
