HAND SA WING MACHIN E.
Specification of Letters Patent.
Patented Feb. 29, 1916.
Application filed April 23, 1915. Serial No. 23,475.
To all. whom it may concern Be it known that 1, PAUL A. VANeso, a citizen of the United States, residing at Rahway, in the county of Union, State of New Jersey, have invented certain new and useful Improvements in Hand Sawing-Machines; and I do hereby declare the. following to be a full, clear,- and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a hand sawing machine.
An object of the invention resides in the provision of a device which may be operated by the ordinary carpentcrs brace.
A further object ofthe invention resides in so constructing the. device'that it maybe used to saw a board from a floor without necessitating the boring of holes in the floor before the sawing operation.
A further object of the invention resides in so constructing the device that when it is being operated the saw will be fed through the work against the action of a spring 1 which will return the saw to its initial position upon the completion of the sawing op-' eration, and the removal of pressure froming within the scope of the appended claim- In the accompanying drawings: Figure l -is a front elevation of my device. Fig. 2 is a side elevation thereof. Fig. 3 s a vertical sectional view taken longitudinally of the saw shaft. liig. 4iis a top plan. View. Fig.
'5 is a horizontal sectional view on line 5--5 of Fig.1. Rig. 6 18 an enlarged detall showing the-manner of mounting the saw upon the shaft.
Referring to the drawings .by reference characters wherein like parts are indicated by like characters throughout the several.
views: In the embodiment of my invention shown in the drawings, 1 have provided a frame which comprises a head 1, and a pair of standards 2 and 3 which are mounted.
uponla base 41. This base is provided witha plurality of spurs 5 which may be forced into the work to secure the frame in position. Each of the: standards 2 and'3 is.pro vided with a vertically extending slot 6, while the head 1 is provided with a pair of parallel holes 7 and 8. This frame is made in two sections, for'convenience of assembly, whichare secured together by suitable bolts9. 1
Mounted between the standards 2 and Sand arranged to have vertical sliding .moveinent, is a shaft support 10 which is of inverted U shaped formation and has a pair of giiidcs 11 formed thereon which are 0perable in the slots 6. Formed on the outer facesof these guides 11 are flanges 12 which bear agalnst the outer faces of thestandards 2 and Rotatably mounted in the legs of the support 10 is a horizontally disposed shaft 13 which has a head 14: on one end thereof bearing against the outer face of the adjacent flange 12. .A second head 15 is formed on. the shaft and bears against the inner face of the adjacent leg of the support 10. These heads 1.4: and 15 prevent the lateral movement of the shaft 13.
The end of the shaft 13'opposit-e to that on which the head 14 is formed is extended beyond the outer face of the adjacent flange 12 and is reduced to form'a shoulder 16. Formed on this end of the shaft is a disk 17 which overhangs the shoulder 16, and provides a chamber 18'. A circular saw '19 is mounted upon this end of the shaft, the hole therein being greater in diameter than the. diameter of the shaft, and less than the diameter of the chamber 18. This saw bears against the face of the disk 17. In order that this saw may be clamped upon the shaft 13, I have provided a plate 20 which has a hole therein through which the shaft 13 passes, and a chamberQl formed therein.-
from the chamber. A coil spring 24. encircles the shaft 13, and bears against the head 23 so as to normally push the sleeve 22,
outwardly. The inner face of this plate 20 is adapted to contact with theouter face of the saw '19 while the sleeve 22 extends through the hole in the saw into the chamber 18. The saw 19 is clamped between the disk 17 and the. plate 20 by a nut 25 which is adjustably mounted on the end of the shaft. j
In' order that the support-.10 may be normally held in a position adjacent the head 1 of the frame, I have secured a coil 5 ring 26 to the bight portion thereof whic exupwardly through the hole 8 in the andis secured to a button 27 which against the upper face of the said the ordinary carpenters brace.
In operating the device, assuming that it is desired to cut a board from a floor, the squared end of the shaft 29 is engaged by the brace, and the frame placed upon the door so that the spurs 5 penetrate the same. The brace is then pushed downwardly until the saw 19 contacts with the floor at which time the crank portion of the brace is rotated. This movement imparts a rotativc movement to the saw. During thisrotativc movement of the saw a constant pressure is applied to the end of the brace which will feed the saw'through the floor against the tension of the spring 526. It will thus be seen that a board may be cut from the floor without necessitating the boring of a hole in the floor or the chiseling of a piece from the floor to accommodate the end of a saw.- It will thus be seen that I have provided.
The upper end of this shaft 29 is- .squared so that it will fit into the jaws of a device which may be readily attached tt and operated by a carpenters brace.
l/Vhde I have illustrated and described" a particular embodiment of my invention it has merely been for the sake of convenience, and I wish it to be understood that I am aware of the fact that numerous changes in the details of construction may. be made, and I therefore do not wish to be limited to the particular embodiment shown any more than is necessary by the scope of the claim.
\Vhat I claim is A portable circular saw machine comprising a frame, a support slidable in said frame, a shaft carried thereby and a saw thereon, a shaft at right angles to and cared to said first mentioned shaft and slidablc with said support in said frame and having an end projecting beyond said frame and adapted to be engaged by a bit-stock to be rotated thereby and to be pressed thereby toward one end of said frame, a spring tending to maintain the support away from one end of the frame so that.
the saw shall not project beyond said end but permitting it to be thrust beyond said end into engagement with work engaged thereby.
In testimony whereof, I ailix my signature, in the presence of two witnesses.
