STANISLAW PRZEPIOBKA, OF MEDINA, NEW YORK.
WOODWORKING-MACHINE.
Specification of Letters Patent.
Patented Apr. 32, 1912.
Application filed May 2, 1917. Serial No. 165,891.
To all whom it may concern:
, Be it known that I, STANISLAW PRZEPIORKA,
a subject of the Emperor of Austria, residing at Medina, in the county of Orleans and State of New York, have invented new and useful Improvements in Woodworking-Machines, of which the following is a specification.
This invention relates to power-driven wood-working machinery, the invention being more particularly related to that type of power-driven wood-working machinery embodying a band-saw.
The main object of the invention is to provide a machine of this character with mechanism adapted to operate upon the wood to be sawed in order to advance the same into the teeth of the band-saw, there being also in view the further object of operating this mechanism from the main drive shaft of the machine.
Another object of the invention is to combine with said feeding mechanism a safety guard which substantially envelope the band-saw abovethe work table so as to prevent the operator or wood-worker from coming into contact with the band-saw, as he performs his work upon the table.
With these and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts hereinafter more fully described and shown in the accompanying drawings, forming a part of this specification, and in which:-
Figure 1 is a perspective view of a woodworkingmachine embodying my feeding device and my guard for the bandsaw blade.
Fig. 2 is a view in front elevation, partly in section, of a fragmentary portion of the machine, illustrating the application of my invention.
Fig. 3 is a View in side elevation. taken approximately on the lines 33 of Fig. 2.
Fig. 4 is a top plan view of the machine embodying my invention, parts being broken away to illustrate my improvement.
Similar numbers refer to similar parts throughout the several views.
The body of the machine consists of a base-plate 10 having a central upwardly projecting standard 11, which merges at one end into an arcuate arm 12 suitably project ing above the work table 13, which is secured to the top of the standard 11 in any suitable manner.
Mounted for rotation in a bearing or bushing 14, suitably provided in the standard 11, below the table 13, is a main drive shaft 15 which carries, on the front side of said standard 11, a band-saw wheel 16, and on the back side thereof (indicated in dotted outline), a fixed pulley 17.
Secured to the rear top side of the arcuate arm 12 is a bracket 19 carrying a longitudinal bearing 20, in which is fixedly secured a short shaft 21, upon the remote end of which is a pulley ring 21 and a pulley wheel 22. both fixed on said shaft.
Also fixedly secured on the top side of said arcuate arm 12 is a bearing 23 in which is fixedly secured a short shaft 24, upon which is mounted for rotation the top bandsaw wheel 25. Mounted upon the band- saw wheels 16 and 25 and rotatable therewith in the usual way is a band-saw 26, which operates vertically through the slot 27 provided in the table 13. Fixed to the front end of the transverse end piece 12 of the arcuate arm 12 is a vertical barrel-like fitting 28, formed with a pair of laterally projecting bearings 29 and 30.
Keyed in the fitting 28 so as to be capable of having axial movement therein, without rotating, is a shaft 31, which is provided on its front side with a series of spaced-apart longitudinal slots 32, in vertical alinement, each adapted for the slidable reception of the inner ends of adjusting screws as 33, which are threaded into the fitting 28, as best shown in Fig. 3.
Fast upon the lower end of the shaft 32 is a casting 34:, the lower end of which is formed with a semi-cylindrical-like shoe 35, which is divided into compartments by equispaced partitions 36. Mounted for rotation in this shoe is a shaft 37 fixedly carrying on its outer or projecting end a bevel gear 38, and also similarly carrying in each compartment formed by the partitions 36. a toothed front end a bevel gear 454, which meshes with a bevel gear 45, the latter gear being keyed between the bearings and 30 upon the vertical shaft 4-6, which is axial y slidahle therein. The lower end of the vertical shaft 4 is journaled in the bearing 4-? provided in the fitting 34, and to the lower end of said shaft 46 is secured a bevel 48 which meshes with the bevel gear 38, by which means the feeding wheels 39 p are driven toward the teeth of the band-saw.
Thus I arrange for the driving of the hunber-feeding mechanism simultaneously with the driving of the band-saw 26, power being communicated from the pulley 17 to the wheel 22 by means of the usual belt L9, and
from the ring 21 to the wheel by another belt 50. Power may be connnunicatcd to the drive shaft 15 from any source of power in the usual way.
In order to prevent the operator working upon the table 13 from coming into contact with the teeth of the saw-blade 26, I provide a safety guard or sleeve 51, for that portion of the saw-blade which extends between the transverse arm 12 and the said table.
This guard 51 is rigidly supported by a ,plate 52 from the rear of the fitting 34:, as best illustrated in Fig. 3. The safety guard 51, thus arranged, is movable limitedly vertically with the limited vertical movements of the fitting 3%, so that when a piece of lumber as 40 is being operatedupon by the band-saw 26, the safety guard 51 may rise sufiiciently to permit the'passage of the lumber and yet have its lower end in close proximity to the lumber so as to prevent the workman from coming into contact with the saw-blade.
From the foregoing description taken in connection with the accompanying drawings, the operation of my device will be obvious. The shoe 35 being cylindrical in form in the direction of the approach of the lumber to be sawed is well adapted upon the 5 engagement of its cylindrical bottom with the end of the approaching lumber to be pushed upwardly within the limits of the length of the notches as 32, and it is also well adapted by reason of such notches to have a vertical movement limitedly in order to conform to irregularities, if any, in the top surface of the lumber.
If the thickness of the lumber to be operated upon is such as to require an adjustment greater than the length of the vertical notches 32, it will be obvious, that by the manipulation of the adjusting screws, as 33, the shaft 32, supporting the shoe 36, may be elevated or lowered as required, in order to permit the engagement of the feeding wheels as 39 with the top surface of the lumber.
Having thus described my invention, what I claim is 1. In a wood-working machine, the combination with a supporting frame including a work table and a band-saw operativcly carried by the frame; of a cylindrical support vertically fixed to the frame above said table in proximity to the band-saw, a shaft adjustably supported in said cylindrical support and adapted to have a limited movement relatively therein, a member having a cylindrical feeding shoe fixed on the bottom of said vertical shaft, a shaft rotatably mounted in said shoe and lengthwise thereof, toothed wheels fixed upon said shaft with their teeth projecting below the bottom periphery of said shoe, and means for driving said shaft, substantially as described.
2. In a wood-working machine, the combination with a supporting frame including" a work table and a band-saw operatively carried by the frame; of a cylindrical support vertically fixed to the frame above said table in proximity to the band-saw, a shaft adjustably supported in said cylindrical sup port and adapted to have a limited movement relatively therein, a member having a cylindrical feeding shoe fixed on the bottom of said vertical shaft, a shaft rotatably mounted in said shoe and lengthwise thereof, toothed wheels fixed upon said shaft with their teeth projecting below the bottom pcriphery of said shoe, means for driving said shaft, and a guard-sleeve rigidly supported from said shoe and movable with the movements thereof, said sleeve encompassing a portion of the band-saw to protect workmen from coming into contact therewith, substantially as described.
3. In a wood-working machine, in combination, a supporting frame including a slotted work table, one portion. of said supporting frame merging into an arcuate arm overhanging said table, a drive shaft rotatably mounted in the frame below said table, a band-saw wheel carried thereby, a band-saw wheel carried by the arcuate arm above the table, a band-saw rotatable upon said wheels and arranged to pass through said slotted work table, a. cylindrical sup port carried vertically by the forward on d of said arcuate arm in advance of the toothed side of said band-saw, a vertical shaft adjustably supported in said cylindrical support and adapted to have a limited movement relatively therein, a feeding member fixedly carried on the lower end of said shaft, said member having a longitudinal shoe With a curved face side, a shaft rotatably mounted in said shoe and lengthwise thereof, toothed Wheels fixedly carried by 5 said shaft With their teeth projecting below the bottom periphery of said shoe, means for rotating said shaft, and a sleeve-guard enveloping said band-saw above the table, said sleeve-guard being fixedly supported from said shoe, substantially as described. 10
In testimony whereof I have signed my name to this specification.
