Specification of Letters Patent.
Patented Nov. 3, 1908.
Application filed July 29, 1908. Serial No. 445,949.
y invention consists of a stretching pincer having a movable jaw, a handle therefor, and a joint for the same, whereby the operation of the handle imparts short, quick and powerful motions to said jaw and tightly .grips the fabric or material to be stretched,
which may be canvass for artists frames, to which, however, I do not limit myself.
For the purpose of explaining the invention, the accom anying drawing illustrates a satisfactory re notion of the same to practice, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.
Figure 1 represents a perspective view of a stretching pincer embodying my invention. Fig. 2 represents a rear elevation of a portion thereof. Fig; 3 represents a longitudinal sectionof a portion on line mm, Fig. 2.
Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawin s :A desi a jaw, which is stationari y connecte with the hollow head B, to which latter is secured in any suitable manner the stationary handle C said jaw being formed integral with the front side of said head making a strong, durable andsimple construction of said parts.
D designates a jaw, which is opposed to the jaw A and movably mounted on the head B by the pivot IE, it being noticed that the face of the jaw A comprises the comparatively flat late F, on which is the transversely extending bead or tongue G, and that the jaw D is adapted to overhang said jaw A, it being seen that the face H of the jaw D which is fiat has therein a transversely extending recess or groove J, which is adapted to receive the tongue G, when the jaws are in closed position.
There may be a plurality of tongues and grooves in the respective jaws, as shown dotted in Fig. 3.
The jaw D is extended beyond the pivot E, forming the heel K, whose terminal is V- shape or pointed, as at L, the same being ates of the movable handle N, which is mounted on the head B by the pivot P, it being noticed that the point L of the heel of the jaw D and the recess M of the handle N, form a knucklejoint, whereby whensaid handle ispressed towards the handle C, the jaw D is moved towards and against the jaw A, thus closing the aws.
In order to open the jaws and return the handle N and jaw D to their normal positions, there is connected with either of the jaws the spring Q, which is adapted to bear against the other jaw, the effect of which is evident on reference to Fig. 3.
On the outer side of the jaw A below the face F thereof is the offset R, which extends into said side forming a shoulder, which is adapted to be rested on a frame, of the fabric to be stretched as a fulcrum, and worked thereon during the stretching operation.
The outward or opening motion of the jaws D is limited by the abutment of the same seated in the V-shaped recess M on the end walls of the recess M also constitutes a tooth,
the teeth intermeshing, so that when the handle N is pressed towards the handle C, it imparts motion to the jaw D to close the same upon the jaw A, and when said handle N is let-'go, said jaw D returns to its normal position. 1
The operation is as follows :The handles are grasped and the jaws presented to the fabric or material to be stretched, so that the latter enters between said jaws. The handle N is then subjected to pressure, so that it moves towards the jaw D, when the jaw D clamps the fabric, holding it tightly between the two jaws. Then the implement is worked on the, frame or the member to which the fabric is applied, when the fabric is stretched, in a convenient, easy and powerful manner, and without liability to slip from the jaws owing to the bight formed by the tongue and'groove of the jaws the latter acting as a bed and holding a reasonable amount of the fabric infiat condition without tearing or cutting it while stretching the portion on the frame.
The jaws may be opened and a fresh hold taken of the fabric, when the operations above stated may be repeated.
Attention is especially directed to the inthe swinging aw and movable handle, whereby the motion of said handle is imparted to said jaw in reverse order, and the increased leverage a fi'orded by said handle causes short, quick and powerful movement of said jaw as it closes on the stationary jaw, while when the jaws are closed, they may be retained easily in such condition as the hand grasps the two handles and easily holds the movable handle under effective control and readily prevents improper opening of the jaws and slipping of the fabric between the same.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1. Pincers of the character described comprising a hollow head having a statiomlry jaw with a fiat bed thereon, a stationary handle fixed to said head, a movable jaw with a flat face thereon, and a movable handle, the adjacent ends of said movable jaw and movable'handle being formed with interengaging teeth.
2. Pincers of the character described comprising a hollow head, a stationary jaw having a flat bed, an overhanging jaw having a Hat face whereby the pincers are adapted to grasp a large surface of a piece of fabric and prevent tearing the same while being stretched, and a stationary handle fixed to said head, the adjacent ends of said handle and overhanging jaw being formed of interengaging teeth.
3. Pincers of the character described comprising a hollow head having a stationary jaw and an offset in its outer side forming a shoulder to engage a fixed object as a fulcrum, a stationary handle fixed to said head, a movable jaw and a movable handle, the adj acent ends of said movable jaw and movable handle being formed of inter-engaging teeth.
4. Pincers of the character described com prising a hollow head having an integral stationary jaw and an offset in its outer side forming a shoulder to engage a fixed object as a fulcrum, a stationary handle fixed to said head, a movable jaw pivoted on said head and a movable handle plvoted on said head, the adjacent ends of said movable jaw and movable handle being formed with intercngaging teeth.
5. In pincers of the character described, a hollow head having an integral stationary jaw and an oli'set in its outer side forming a shoulder to engage a fixed object as a fulcrum, said head being designed to serve with a stationary handle, a movable handle and a movable jaw.
G. Pincers of the character stated consist ing of a stationary jaw, a swinging jaw, a stationary handle, a movable handle, a head, to which said stationary jaw and stationary handle are attached, and on which said swinging jaw and movable handle are pivotallymounted, and an offset on the exterior of said stationary jaw below the operating face thereof, said swinging jaw and movable handle being adapted to inter-mesh.
