BUCK-SAW.

PECIFICATIN forming part of Letters Patent No. 326,045, dated September 8, 1885.

` Application filed June 13, 1885. (No model.) Y

.To all whom it may concern:

Be it known that I, ALBERT H. LoEBs, of Rochester, in the county of Monroe and State of New York, have invented certain new and A useful Improvements in Buck-Saws; 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.

My invention relates to an improvement in buck-saws.

A common objection to the buck-saws as hitherto constructed is the vibratory motion of the blade as the saw is forced forwardly through the cut, oftentimes producing such a resistance as to materially obstruct its progress and cause great annoyance to the operator. It also often becomes a matter of great convenience to hold the work with one hand, or assist in holding it, and operate the bucksaw with one hand only. This is particularly the case when the final cut is reached in sawing a long stick into short lengths. As hitherto constructed it has been necessary, wh en one hand only is used, to grasp the head of the saw-frame either above or below the sawblade, thereby driving it to a great disadvantage.V Y i The object of my present invention is tc provide a buck-saw which shall be free from the objectionable vibratory motion of the blade, and which will admit of being grasped with one hand at the most advantageous point for Work, thereby combining in one saw the advantages of a buck and hand saw.

With these ends in View my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

The accompanying drawing represents the saw in side elevation.

A represents the head or handle end of' the saw-frame, and B the foot.

The saw-blade Cis secured to the lower end of the foot and near the lower end of the head, as is usual in saws of this character. The upper ends of the head and foot frames are connected by a longitudinallyadjustable rod, D, for regulating the tension of the saw-blade. Between the saw-blade and the adjustingrod D the bifurcated brace E is located, the two branches of the brace serving to prevent the rocking motion of the parts, which is a very objectionable feature in the single-bar-brace construction in quite general use. The sawblade C gradually increases in width from the foot toward the head, the teeth c occupying nearlyor quite a straight line, and the back of the saw being on a slight curve, as shown. The teeth near the end may be smaller than those near the head, the increase being gradual from the foot toward the head, or they may be of like size throughout, as found most desirable. y

As pressure is applied to the upper and lower portions of the head A in driving the blades through a cut, thesaw moves at iirst at a slow rate, but as the arms gradually straighten its speed increases, and the weight of the operator is thrown more directly onto the blade to cause it to cut as deeply as possible. The gradual increase in the width ofthe blade and size of the teeth serves to keep the strength and stiffness of the saw at all points of its stroke adequate to the pressure and speed, and prevents the vibratory or jarring motion which has hitherto proved objectionable. l

At a point in the head-frame A directly opposite the end of the saw-blade the headframe is widened, if necessary, to admit of an oval or other convenientlyshaped opening, F, being formed therein transversely to the length of the saw. The portion of the frame A in front of the opening F is rounded in shape to form a good grip for the hand of the operator. By grasping the frame at this point the buck-saw may be used as a handsaw, and the pressure from the hand of the operator may be applied in such a direction relatively to the resistance of the saw that its cut will be effective.

It is evident that slight changes in the forms of the parts and their relative arrangements might be resorted to without departing from the spirit and scope of my invention-#for example, the handle opposite the head of the saw-blade might be attached to the front of the frame A, and might be of various forms other than that described. Hence I do not IOO head and foot section, the former being prowish to lilnit myself strictly to the construetion herein Vset forth; but,

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

1. In a bueksaw, the e0n1bination,with the vided at a point between its ends with a supplemental handle, F, of a saw secured to the lower end of the foot-section, and to head-section at a point opposite the handle F, and braces connecting the head and foot sections, substantially as set forth.

2. In a buck-saw, the combinatiomwith the head and foot sections, the former being pro- ALBERT H. LOEBS.
