SAW-VISE No. masas.

Specication of Letters Patent.

Patented April 13, 1909.

Application vfiled April 21, 1908. Serial No. 428,429.

To all whom it may concern:

Be it known that I, JOHN LJUNG, a citizen of the United States, residing at Alexandria, in the county of Douglas and State of Minne- Sota, have invented a new and useful Saw- Vise, of which the following is a specification.

'lhe invention relates to improvements in saw vises.

The object of the present invention is to improve the construction of saw vises, and to provide a simple, inexpensive and etti cient one of great strength and durability, adapted to clamp. uniformly throughout its length either narrow 'or wide bladed saws without ermitting one end of a saw blade to vibrate oosely within it when the teeth of the saw are being filed.

Another object of the invention is to provide a saw vise having a pivotally mounted saw clamp, adapted to be arranged at difierent angles or inclinations andl secured in its adjustment by the means for attaching it to a bench or other sup ort.

With these and ot er objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated 1n the accompanying drawings, and pointed out in the claims hereto aplpended; 1t being understood that various c anges in the form, proportion, size and minor details of constructlon, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing an f of the advantages' of the invention.v

n the drawings:-Figure 1 isa perspective view of a saw vise, constructed in accordance with this invention. Fig. 2 is a side elevation, showing the o posite side of the saw vise. Fig. 3 is a si e elevation of the saw. vise, illustrating the manner of clamping a wide bladed saw. Fig. 4 is a vertical sectional view on the line 4-4 of Fig. Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 3. Fig. 6 is a detail persppctive view of the angle locking lever.

L1 e numerals of reference designate corresponding parts in all the figures of the drawmes.

tThe saw vise includes a saw clamp rovided width a horizontal pbivot 1, ada te to ermit the saw clamp to e arrange Aat diferent angles and inclinations, and supported by a bench clamp, composed of an upper straight horizontal member 2 and a substantially L-shaped member 3, consisting of a vertical arm or portion and a horizontal arm or portion. The upper horizontal member is provided at one end with a jaw 4 for engaging the upper face of a bench 5, or other suitable support, and the other end of the member 2 is provided with a slot or bifurcation 6, which receives the upper end of the vertical portion of the L-s iaped member. The upper end of the vertical portion of the L-shaped member 3 and the bifurcated end of the horizontal member 2 are provided with registering openings for the reception of the pivot 1. The lower horizontal arm of the L-shaped member is provided with a threaded opening 7 for the reception of a clamp or tiumb screw 8, pivotally connected at its upper end to a horizontal jaw 9 for engaging the lower face of the bench 5. The lower end of the screw 8 is provided with a suitable head for enabling it to b'e readily grasped and operated. The L- shaped member is provided at the upper end or portion of its vvertical arm with opposite shoulders 10, and the sides of the bifurcation 6 have straightedges 11, which engage the shoulders .10, whereby when pressure 1s applied byA the screw 8, pressure will be transmitted to the pivot 1, 'which will be frictionally clamped by the members 2 and 3 of the bench clamp with suflicient force to hold the saw clamp 1n its adjustment.

The saw clamp is provided with a substantiallyU-sha edbod 12,havingoneof its arms extended a ove t e other and carrying a relatively xed jaw 13, formed integral with the U-shaped body of the clamp. The jaw 13 is V-shaped 1n cross sectlon and cooperates With a corresponding V-shaped jaw 14, arranged in substantial parallelism with the jaw 13 and adapted to :fit within the same, as clearly shown in Figs. 1 and 2 of the drawings to clamp a narrow saw blade. When it is desired to clamp a key hole saw, or similar narrow bladed saw, the ljaws are arranged with their outer cooperating portions m vertical planes. The U-sliaped body portion is arranged at an inclination, when the outer engaging portions of the

jaws

13 and 14 are vertical. When it is desired to clamp a wide blad'ed saw, such as a'n ordinary carpenters saw, the body portion oi' the saw clamp is arranged in a vertical position and the 'aws are moved beyond an intertting position to provide aclear space between them, as shown in Fig. 3 of the drawings. This brings the wings or sides of the V-shaped jaws in an inclined position, the relatively fixed jaw presenting two engaging edges to the saw blade, and the movable jaw presenting a single engaging edge located at an intermediate point between the upper and lower engaging edges of the fixed jaw.- lllhen the saw clamp is arranged in this position, it is' adapt-ed to accommodate a wide blade, which may extend into the space between the sides of the U-shaped body 12.

The movable or adjustable aw 14 is formed integral with a central sliank 15,pivoted at an intermediate point to the upper end oiI the short side of the U-shaped body by a boltI 16, or other suitable fastening device and forming a lever. The lever formed by the shank has a short upper arm and a long lower or depending arm, which is adapted to be engaged by an angle looking lever 17. The angle locking lever 17, which consists cl' a Short arin 18, arranged at an angle to the lon arm, is fulcruined at its angle on the body 12 at the bottom thereoiI by means ol' a bolt 19, or other suitable pivot. The body is provided at its lower portion with a boss 2U, which spaces the angle locking lever from the body to provide a space for the shank or lever oi' the adjustable jaw. The lower or depending arm ofv the shank or lever 15 is provided at its lower portion with a notch 21, located at the inner edge oi' the shank and adapted to be engaged by studs 22 and 23. The stud 23 projects from the inner face of the long arm of the angle locking lever, and is adapted to engage the said notch 21 when the

jaws

13 and 14 engage a saw having a wide blade. The other stud 22, which is located a greater distance `from the pivot 19 than the stud 22, projects from the inner face oil the short arm 18 of the locking lever and engages the recess or notch 21, when the

jaws

13 and 14 are arranged i'or clam ing a narrow saw blade. The lower arm o` the shank or lever 15 is also provided with a sto 24, consisting of a stud and arranged 'to e engaged by thelocling lever to limit the upward swing oi' the long arm of the same.

The jaws, whether engaging a wide saw blade or a narrow saw blade, fit against the same and uniformly clamp the saw blades throughout their entirey length so that one end or portion oi' the saw blade will not be left free and permitted to vibrate when the saw teeth are led. The ,pivotal movement oi" the saw clamp enables the angular or Vfshaped jaws to be arranged forrholding either a wide or narrow blade in a vertical position and by tightening the screw 8, suHicient pressure is produced on the pivot 1 of the saw clamp to hold the latter in its adjustment while the saw teeth are being led.

Having thus fully described my invention,- what l claim as new and desire to secure by Letters Patent, is

1. A saw vise including a saw clamp provided with a pivot, and a bench clamp composed of two members connected togetherv by the said pivot and having means l'or engaging each other, and adjusting means carried by one oil the clamp members and cooperating with the. other to engage a bench ci' support and adapted also to )roducc ressui'e on the pivot for holding t e sawc amp in its pivota adjustment.
