S.PEGIFIGATION forming part of Letters Patent No. 529,778, dated November 27, 1894.
Appumionrled April 24,1894. y
.To all whom it may concern:
Be it knownthat we, HERMANVBULLOCK, of Crosby, and CHARLES E. WARD, of Penn Yan, 1n the county of Yates and State of New York, both citizens of the United States, have invented certain new and useful Improvements in Driers, of which the following is a full, clear, and exact description, such as will enable they appertain to make and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which forma part of this specica'- lon.
Figure 1, is a vertical sectional view of the drier, the intermediate part being broken away. Fig. 2, is va side elevation of the same. Fig. 3, is an end view on theline -.r of Fig. 1,l with the end wall of lthe drier removed. Fig. 4, 1s a plan view of the apparatus on the linee-e, Figs.l 1 and 8, which merely removes the top wall or covering of the drying chamber. Fig. 5, is a view in.` detail of the belt and connecting'mechanism about to pass one of the frame sections by the rollers to the lower plane, and Fig. 6, is a View in detail. of one of the wood veneer pieces for drying.
Our invention relates to an apparatus for drying veneer wood, berries, fruits and substances `applicable to its operation and use, and in which the drying agent is of an artificial character, such as superheated steam, hot air or the combination' of the two. Our apparatus is designed most especially for the drying of thewood veneer pieces, so extensively madeuse of in the manufacture of baskets, and other articles made from that material.
The invention consists of the novel features and combinations of parts hereinafter more fully described and set forth, and pointed out in the claims.
The devices made use of to eect and carry out the spirit of the invention willpbe more particularlydescribedhereinafterand poin-ted out in the claims.
We are aware that it is old to provide an artificially heated chamber with .a series of endless belts, providing only a continuous traveling surface to carry the stoc'k by its transfer from the advancing portion of one sans No.' 508,904.. (No mods.)
I belt to that of another. Such does not meet o r anticipate the provisions of our invention, which contemplates sections, means for the .continuous advancement of the said sections through the drier, and provision for automatically operating the sections to cause them to discharge the stock andother articles placed thereon after being dried.
Like letters and figures on the drawings in-l dicate corresponding parts astheyare referred to in the following description:
a a represent side walls, b b the end walls and c cthebottom and top walls of an oblong rectangular shaped chamber, ,into which the artificially produced heat for drying is introduced and retained at the proper degree.
l represents the supply pipe and 2 the distributing pipes, through which the steam or other heated medium is passed for heating the said chamber. The location and introduction of these pipes are variable, and immaterial so long as they o'ccupythe intervening spaces between the folds or return portions of the carrier best adaptedr to eect the drying of the material, and to not interfere with the working mechanism.
3 and 4 represent longitudinal stringers, 5 cross ties, and 8y the vertical standards of a suitable` frame work provided t'o'brace and strengthen the walls of the drying chamber, and give thereto the rigidity essentialto its stability and the provision of firmer supports for the journals of the sprocket rollers 7 over which the belts or carrier chains 13 travel.
At the front end of the drier and opposite to each 'other are the standards 8 arranged in vertical relation and adjustably secured at their ends to the stringers 3 and 4 by provision of the tenons 9 to the standards, proj ecting into and through the vertical mortises vl0 in the Stringer.
1l represents sprocket wheels rigidly mounted upon journals12, which are ar- .ranged to revolve in suitable bearings through the side walls a o. of the drier. The inner ends of these journals are provided with the sprocket rollers 'Z rigidly attached vthereto close to the walls of the chamber. There is an equal number of rollers on each side of the chamber, those on one side being arranged in coincident relation with the rollers on the opposite side. The rollers are disposed in vertical series near each end of the chamber,
` and the rollers of one seriesare arranged opposite the spaces between the rollers of the other series in horizontal planes to give the carrier a zigzag appearance and support it at the folds. The belts or chains 13 pass over these rollers and constitute the carrier. The front wall i) is provided with slots or narrow openings 14 and 15, through which the carrier passes in its travel in and out of the drying chamber. Rollers 16 hung to revolve with the shaft 17 which is journaled at its ends in the lower portion of the standards S support the carrier belts 13 at their lower forward portions opposite the opening` 15. The rollers 18 arranged on the upper portion of the said standards support the carrier belts at their upper forward portions. It will thus be seen that the carrier belts are arranged in a continuous and endless manner on the sprocket rollers, and that any expansion thereof can be taken up simply by moving the standards S, the latter operation being effected by set screws 2O turning in nuts 21 provided in the standards 8. The set screws 2O pass through the standards and the nuts 21 and bear at their inner ends against plates 19 on the opposite end wall of the drier. The heads 22 of the set screws have flattened sides to receive a wrench or other toel by means of which the set screws are `turnsd to properly adjust the standards 8. Y
23 represents rectangular shaped sections or framed sieves arranged in a series to follow each other in close relation, and with ability to turn or revolve on studs 24: projecting inward from the carrier belts 13 and eXtending through the openings centrally provided in the opposite sides of the sieve frame. Projecting from the side wall of the chamber, sufficiently to catch under the edges of the traveling sections or sieves 23 are the ways 25 which are extended alternately from the opposite ends :of the drier chamber along the path of the belt to Within about one-half of the length of the sieves in distance from each succeeding roller. The carrier belts with the edges of the sieve frames or sections traversing along on the ways thus provided are supported when loaded and retained in proper position. By reference to Figs. 1 and 5 it will be seen most clearly how the sieves or sections are kept in horizontal or proper position whilethey are passed by the rollers, reversing their positions relatively to the carrier belts, and beginning the movement in an opposite direction. f
26 represents an oscillating arm pivoted to the edge of the way above or to blocks for that purpose, as indicated by 27. This arm is extended down to be struck by the advancing edge of the sieves so as to be actuated and swung back. The block 23 serves to hold the sieve in its line of advancement until it is carried over and engages with the swinging arni. Passing across the chamber and over the carrier near the rollers, and hung te rock in the side walls of the drier, is the rocking shaft 29. This shaft opposite to the oscillating arm is bent on itself to provide two opposing loops or crank portions which constitute a lever 30. A pitman 32 connects the arm 26 and the loop o"r crank of the lover 30. As the arm 2G is drawn back by the advancing section or sieve, the shaft 29 through the medium of the pitman 32 and crank portion of the lever 30 is caused to rock, bringing the free loop or crank in engagement with and pressing down upon the rear end of the sieve frame while the latter is being forwarded on its pivots around the rollers of the ways 25 below. In this way the rear of each succeeding sieve becomes the advancing end, and the arm 26 being relieved by the departure ofthe section or sieve, the shaft 29 is rocked back, returningthe mechanism to its normal position. This is effected by the advancing edge of the section or sieve frame striking against the free loop or crank portion of the lever 30 while passing under the shaft 29.Y The arm 23 is in this manner set to be again operated in the manner set forth. A d
On the shaft 17 are mounted the rollers 33 arranged in line with and rolling on the side bars of the frames as the belts carry them beneath the rollers and suddenly begin their elevation. The frames in this manner are given a momentum and caused to revolve bottom side up on their pivots in the course indicated by the dotted lines 34E asthey are advanced to the dotted position 35. At this point the belts are confined to continue passage between the guide rollers 36 and 37. The inner rollers 36 are loosely journaled on studs 3S projecting from the standards 3. The outer rollers 37 are mounted in the path of the sections or frames 23 upon shaft 39 supported at its end in the standards 8. The sections or frames striking these rollers 27 are caused to again reverse in position as shown at 40. As the carrier travels upward as shown by the arrow Z, the section or frame will engage with rollers 4:3 en the shaft 44: and be swung against the guides 45 to be prepared and brought into proper position to enter the opening 14. The dotted line 42 indicates the path traversed by the sections in their vertical travel from the lower to the higher plane. The sieve frames or sections are successively relieved of their load as they approach the reversed position indicated by the dotted lines 35 andwhen they assume the position 41 are again loaded with the stock, articles or substances to be dried.
As it may be desired to build the drier of great length it will be necessary to provide suicient means for the application of power to the apparatus. For this purpose the j ournals 12 are extended through the walls of the drierwand supported withV sprocket wheels.
11. These sprocket wheels 11 may be connected by belts as ^indicated by dotted lines 4.6 in Fig. 2 to similar sprocket wheels over` roo head provided on counter shafts by means of which motion is imparted to the carrier. As these counter shafts and their connections form no part of the invention it is not deemed necessary to illustrate the same in connection with the application.
Having thu's described our invention, what we claim as new, and desire to secure by Letters Patent, is-
l. In a drier an endless carrier passing through the drying chamber in a zigzag direction and provided with pivoted sections, of controlling devices at the ends or turns in the carrier disposed to act positively on both ends of the sections to hold them -in a horizontal position during their passage from one level to another, substantially as described.
2. In a drier an endless carrier passing through a drying chamber in a zigzag direction and provided with pivoted sect-ions, of a shaft journaled above the carrier a short distance from its fold or turn having a laterally projecting portion, a pivoted arm arranged a short distance from the said turn and adapted to be engaged by the advancing edges of the sections, and a connection between the arm and the said shaft, substanti ally as described.
3. In combination with a drying chamber having egress and ingress openings, respectively, carrier adapted to traverse the drying chamber and comprising pivoted sections, supports for the said carrier exterior to the drying chamber nearly opposite to the said openings, and means intermediate the said supports to engage with the pivoted sections and turn them on their pivotal supports, substantially as described.
4. In combination with a drying chamber having ingress and egress openings, respectively, near its top and bottom, of an endless carrier operated to traverse the drying chamber, a relatively movable upright exterior to the drying chamber, supports on the upright about opposite the said lingress and egress openings, and tappet devices mounted on the upright and adapted/to engage with the said sections and turn them on their pivots, substantially as described. p
