SAWMILL Filed Feb. 5, 1932 5 Sheets-Sheet 5 I n uenior By @MM A llomey Patented Aug. 30, 1932 PATENT OFFICE OMER EDWARD HAUIBROCK, OF BRISTOL, TENNESSEE SAWMILL Application filed February 3, 1932. Serial No. 590,891.

The present invention relates to saw mills .and has for its primary object to provide, in a manner as hereinafter set forth, an apparatus of this character embodying a plul rality of complete mobile units adapted to be readily transported from place to place and expeditiously coupled together at any desired point in a manner to provide a complete saw mill.

Another important object is to provide a saw mill of the character described embodying novel means for conveniently coupling the units together for operation and for supporting said units.

vide a saw mill of the character set forth which will be simple in construction, strong, durable, efficient and reliable in operation and which may be manufactured at low cost.

All of the foregoing and still further obects and advantages of the invention will ecome apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corre: sponding parts throughout the several views, and wherein Figure l is a view in top plan showing a saw mill in accordance with this invention, the units being assembled and ready for operation.

Figure 2 is a view in side elevation thereof. Figure 3 is a view principally in end elevation and partially broken away in vertical transverse section showing the means for connecting together and supporting in side by side relationship the carriage unit and the saw unit.

Figure 4 is a detail view in perspective of 7 Other objects of the invention are to proconnecting the drive shaft sections of the units together.

Figure 8 is a detail view in vertical section through one of the supporting jacks.

Figure 9 is a view in horizontal section taken substantially on the line 9-9 of Figure 8. v

Figure 10 is a detail view in perspective showing additional means for connecting the longitudinally aligned units together.

Figure 11 is a detail view in perspective showing a portion of the means for connecting the carriage, saw and edger units together.

Figure 12 is a detail view in front elevation of the latch.

Figure 13 is a View principally in top plan and partially in horizontal section of the latch.

Figure 14. is a detail view in perspective showing the upper end portion of one of the jacks.

Referring now to the drawings in detail, it will be seen that the reference character A designates generally a carriage unit, B designates generally a saw unit, C designates generally an edger unit and D designates generally a trimmer unit. Each unit is preferably in the form of a trailer and, in the embodiment illustrated, comprises a frame 1 having a platform 2 thereon, said frame being mounted on the supporting wheels 3.

Mounted on the unit B is a saw 4. Although a band saw has been illustrated, it is understood, of course, that a circular saw may 85 be used. An edger mechanism 5 is mounted on the unit C and a trimmer mechanism 6 is mounted on the unit D. Mounted on one side of each of the units B, C, and D is a drive shaft section 7 which extends longitudinally. The shaft sections 7 are journaled for rotationv in suitable bearings 8. When the saw mill is assembled, the shaft sections 7 are coupled to each other by suitable means, such as a sleeve 9 having set screws 10 therein, as best seen in Figure 7 of the drawings. In this manner a drive shaft is provided which may receive its power from any suitable source. A carriage mechanism 11 is mounted 100 on the unit A. Said carriage is movable on a railway 12 which projects alongside the unit C, Figures 1 and 2. The carriage mechanism 11 may be actuated in any suitable manner.

6 Referrin now to Figures 3 and 4 of the drawings, it will be seen that the forward end portions of the units A and B are connected together by means which includes a bolt 13 extendi through the adjacent sides of the frames 0 these units, a spacer 14 being provided on the bolt between the frames. Extending transversely beneath the forward end portions of said units A and B is a clamp bar 15 having upturned apertured end por- 15 tions 16 through which the clamping screws 17 are threaded for engagement with the frames for clamping said frames together. At

spaced points the lower side of the clamp bar 15 is provided with pairs of sockets 18 for a pn ose which will be presently set forth.

A similar clamp bar 15 extends transversely beneath the rear end portion of the units A and B, Figure 2.

The ad acent ends of the longitudinally an aligned units B, C and D are detachably connected together by means which includes latches 19 pivotally mounted for swinging movement in vertical planes in bearings 20 on one of said adjacent ends, said latches being 80 engageable in openings 21 provided therefor in the adjacent end of the adjacent unit. This is illustrated to advantage in Figure 5 of the drawings. A connecting means for the longitudinally aligned units B, C and D furas ther includes the detachable side plates 22 secured by nut equipped bolts 23 to the sides of the frames of these units. As illustrated to advantage in Figure 11 of the drawings, the rear end of the unit A is connected to the adjacent ends of the units B and C through the medium of an angle iron 24 which abuts the adjacent plate 22 and is secured thereto by the bolt which secures said adjacent plate 22 to the unit G.

The units, when assembled, are raised and levelled on the supporting jacks designated generally by the reference numeral 25. The embodiment of supporting jack illustrated comprises a plurality of angle iron legs 26 which diverge downwardly from a block 27 having a threaded, vertical bore therein in which is engaged a screw 28. A head 29 is mounted for universal movement on the upper end of the screw 28 and is provided with 68 a pair of upstanding pins 30. Braces 31 are provided for the legs 26. A nut 32 is threaded on the screw 28 and engageable with the block 27 for raising and lowering said screw. The jacks 25 are engaged beneath the clamp bars 15, beneath the railway extension 12 and beneath the frames of the units B, O and D in the manner illustrated to advantage in Figures 1 and 2 of the drawings. The sockets- 18 in the lower side of the clamp bars 15 are for the reception of the pins 30 on the heads 29 of the screw jacks. The portions of the extensions 12 and the units B. O and D which are engaged by the screw jacks are also provided with pairs of sockets for the reception of the pins. In this manner accidental disengagement of the heads 29 is prevented.

The latches 19 and the openings 21 are so formed that when the units B, C and D are moved together, the latches ride upward in the openings and dro to operative position. To this end, the late es 19 include sto s 33 engageable with the frames upon whic the latches are mounted for supporting said latches in proper position to enter the openings 21.

As will be apparent, the units may be conveniently transported from place to place, as

a train, being drawn by a single draft vehicle, such as a tractor or motor truck. When the desired location is reached, the units are operatively coupled together or assembled and raised on the supporting jacks 25 and the saw mill is ready for operation. T hen, when it is desired to again move to a new location, the supporting jacks are removed, the units are disconnected and coupled together in a train and are ready to be again moved.

It is believed that the manyadvantages of a saw mill constructed in accordance with the present invention will be readily understood, and although the preferred embodiment'of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
