Patented Dec. 27, 1938 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to an apparatus for mechanically brewing pulpwood and a suitable construction is set forth in the following description and illustrated in the accompanying draw 5 ings, in which,
Fig. 1 is a side elevation of a browing machine constructed in accordance with the invention.
Fig. 2 is a detail view of the means for elevating or lowering the sections.
Fig. 3 is a detail view showing 'ing mechanism.
Fig. 4 is a plan view of the power drive.
Fig. 5 is a cross section on the line 5-5, Fig. 4, showing in addition part of the conveyer.
Fig. 6 is a cross sectional view of the conveyer belt on the line 6-6, Fig. 1.
Fig. '7 is a fragmentary side elevation of the conveyer belt.
Like characters of reference refer'to like parts throughout-the specification and drawings.
The brower consists of five movable conveyer sections ll, l2 and I3 which are each six feet long and I4 and I5 which are five feet long. Each section is pivotally connected to the adja- 26 cent section and the middle section I3 is pivotally mounted on the frame work I6 so that it can be brought up or down. The framework I 5 is pivotally mounted on the frame H, which is mounted on the vehicle having tractor treads l8.
This design of the sections of the brower allows the sawn pulpwood to be delivered to the brow at various heights as shown by the five positions, A5, B5, C5, D and E5. It will be noted from this construction that in moving the brower from 35 one position to another that sections I5 and H can be folded back on section l3 and section No. II can be folded back on section No. I 2, and I 3 lowered to rest on its bearing formed by the framework Hi. This makes a very compact ar- 40 rangement for transporting.
In operation, the brower works across the supporting frame and is swung lengthwise for moving. The framework It, upon which the section I3 is mounted, forms a turntable which is pivot- 45 ally mounted on the axis l9.
The brower is powered bybelt or chain drive from the front power take off of the tractor used in skidding. For this purpose, the brower is provided with a driven pulley 20 which, through a 60 suitable arrangement of gears, drives the conveyer heretofore described.
In Figs. 4 and 5 is shown the means for driving the conveyer 2| and this consists of the pulley 20 and gear box 22 which houses a suitable train part of the drivof gears 23 for reducing the speed of rotation. The gear train 23 drives the shaft 24 which is provided with a bevelled gear 25. Housed in the axis I9 is a driven shaft which is provided at its lower end with a bevelled gear 26 meshing .with 5 the gear 25. The upper end of the last mentioned shaft is provided with a bevelled gear 21 which meshes with a bevelled gear 28 mounted on the frame 16. The shaft 29 on which the gear 28 is mounted is provided with a pulley over 10 which the belt 30 passes. The belt 30 drives a pulley wheel 3| over which the conveyer belt 2| passes. The means for adjusting the height of the conveyer to positions A5, B5, C5, D5 and E5 shown in Fig. 1 consists of a cog-wheel 32.which 15 is mounted on the shaft 33, the shaft 33 pivotally connecting the adjoining ends of the several sections forming the conveyer. In the construction shown, the cog-wheel 32 is so mounted or connected to the section l5 that upon rotation of the cog-wheel 32 clockwise, the section l5 will be raised and upon rotation in the opposite direction, section l5 will be lowered. Meshing with each cog-wheel is a cog-wheel 34 which is mounted, on the end of the section adjoining the one to which the. cog-wheel 32 is connected. The cog-wheel 34 is rotated by a crank 35 and is locked by a pawl 36.
In operation, the sawn pulpwood lengths are carried direct from the sawing machine and placed on the apron or section II of the brower, the brower having been adjusted first to the correct elevation. The brower delivers sawn pulpwood to the brow where it is piled in blocks.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:
A mechanical browercomprising a framework supported on a carriage, a turntable mounted on said framework, a movable conveyer formed of a 40 plurality of sections mounted on said turntable, one of said sections being hinged to said turntable for vertical movement, a shaft pivotally connecting each section to an adjacent section permitting each section to be swung on said shaft to different positions and means carried by each section for moving the same to different positions comprising a cog wheel carried by each shaft and attached to the end of one section, a second cog wheel meshing therewith carried by the adjoining section, a crank for rotating said second cog wheel and a pawl engaging with said second cog wheel.
