Description
Patented Mar. 21, 1950 UNITED STATES PATENT QFFICE 1 Claim.
The present invention relates to new and useful improvements in saw sets, and more particularly to a device of this character adapted for setting the teeth of saws and embodying means for setting the teeth at opposite sides of the saw.
It is the cardinal object of the inventionto provide a saw tooth setting device which will insure a perfect set of the teeth of a saw, regardless of the thickness of a saw tooth, and the invention embodies the provision of pins adapted for use at the respective sides of the saw and adapted upon delivery of an impact to the pins to set the teeth at a desired angle.
A further object of the invention is to provide a device of this character of simple and practical construction, which is eicient and reliable in use, relatively inexpensive to manufacture, strong and durable, and otherwise well adapted for the purposes for which the same is intended.
Still a further object of the present invention is the provision of a device of the character described whose pins have head portions specically designed for the setting of several teeth simultaneously, and said pins being interchangeable with pins having differently formed head portions, so that my new and improved device can be used also for punching, crimping and other sheet metal work.
With the foregoing and other objects in view which will appear as the description proceeds,
the invention consist of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
In the accompanying drawings the preferred forms of the invention have been shown.
In said drawings:
Figure l is a top plan view of a preferred embodiment of my invention with the top portion fractionally broken away;
Fig. 2 is a sectional view on the line 2-2 of Fig. l;
Fig. 3 is a sectional view on the line 3-3 of Fig. 1;
Fig. 4 is a detailed side view of a pair of pins for sheet metal work;
Fig. 5 is a front view of one of the pins of Fig. 4;
Fig. 6 is a detailed side view of a pair of punching pins;
Fig. 7 is a front view of one of the pushing pins of Fig. 6;
Fig. 8 is a detailed view of another pair of pins for sheet metal work; and
Fig. 9 is a front view of one of the pins of Fig. 8.
Similar reference characters refer to similar parts throughout the several views.
In the drawing the numeral I denotes a casing from one of whose side walls extends a stationary handle 2, which preferably is formed as a unit with the casing I, and whose top wall has a reinforced perforated center portion 4I) that is formed as a groove extending crosswise through the lower portion of the casing. A normally vertical lever 4 which is extended into the casing I through the perforated top portion 3 is tiltably secured thereto by means of a cross pin 5, which extends through the lever l and is extended at both ends into the casing I (Figs. 2 and 3) The portion 6 of the lever 5, which extends into the top portion 3 as well as into the casing I, preferably is bifurcated, and connecting rods 5 and I0 are linked to the end sections of the bifurcated portion 6 by means of pins l and 8 respectively. The upper extremities of the vertical portions of a plurality of angular members I5 are connected to the outer extremities of the rods 9 and I [I respectively by means of shafts 42 extended therethrough, and the members i3 are pivoted at both sides of the lever 4.- to lug portions I9 of the casing I by means of shafts 4I (Fig. 2). The lower parts I4 of the casing at both sides of the groove 40 are detachably secured to the casing i by means of screws 2I, which extend through the parts I4 and engage internally threaded bores in the lug portions 22 of the casing I (Figs. 1 and 2). The parts I and I4 are provided with upwardly extending registering panel portions I8, and a plurality of horizontal pins I5, which register with the horizontal portions of the angular members I3, are slidably extended through the panel portions I8 as well as through the vertical wall sections of the U-shaped bottom portion 40. Those portions of the pins I5 which extend into the grooved U-shaped bottom portion 4t are formed as heads I6, which have serrated face sections adapted for engaging the teeth of a saw. A spring I'I is interposed between the outer vertical wall section of the grooved U-shaped bottom portion 40 and a washer 43, or a cross-pin or the like, which is secured to each pin I5. The springs I'I tend to force the pin heads I6 away from the center of the U-shaped groove 4G upon releasing the lever 4. If the latter is tilted, the parts 'I to I0 and I3 force the pins I5 and their heads I0 toward the center of the U-shaped groove 40, so that the heads l act upon the teeth of a saw. The latter is indicated by dash-and-dotted lines and denoted by the numeral 44 in Figs. 1 and 2. In order to steady the setter on the saw 44, and to prevent bending of the latter, I prefer to extend the lower lateral end portions 23 of the part i4 beneath its lower edge 20, and to provide in the end portions 23 threaded bores into which are screwed bolts 45. One extremity of each bolt 45 is provided with a slot 48 (Fig. 2) adapted for being engaged by a screw driver (not shown), while the opposite extremity of each bolt 45 is provided with a head 24, which preferably is shaped semi-spherical, or oval, or which is of any other suitable shape and is adapted for laterally engaging the blade of a saw 44, inserted into the groove 4D.
While the pins I5 with their heads i6 are adapted for the setting of saw teeth, said pins i5 can be removed from the device after disconnecting the parts I4 from the casing l, and other pins with differently shaped head portions can be substituted for the pins I5. For instance, pairs of pins 2l having heads 25 as shown in Figs. 4 and 5 can be used as so-called hand breaks for sheet metal work; or pairs of punch pins as shown in Figs. 6 and 7, each pair consisting of a pin 3| having a head 23 with a bore 3S and another pin having a head Z9 or pairs of crimper pins as shown in Figs. 8 and S, each pair consisting of a pin 3Q having a tl-shaped female head S2 and of a pin having a male head 33 can be used.
Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claim is intended to cover all of the generic and specic features of the invention herein described, and all statements of the scope or" the invention which as a matter of language might be said to fall therebetween.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:
A device of the character described comprising a casing whose top wall has a perforated center portion and Whose bottom has an upwardly extending U-shaped center portion forming a groove which extends through the lower portion of the casing, a stationary handle being laterally extended from one of the side walls of said casing, a normally upright lever extended into said casing through the perforated top of said casing being tiltably secured to the latter, a plurality of horizontal movable pins extending from opposite directions through the vertical wall portions of said groove, resilient means attached to said pins for forcing them away from the center of said groove, angular members whose horizontal extremities register with the extremities of said pins being pivotably secured to said casing within the latter, connecting rods being hinged with one of their ends to the vertical portions of said angular members and with the other one of their ends to said lever, and lengthwise adjustable bolts extending into said groove being provided at the lateral extremities of said casing, those portions of said pins which extend into said groove being formed as heads, and said pins being interchangeable with pins having differently formed head portions, all substantially as described.
