Description
Sept. 23,1952 M. SCHIFFBAUER M'EsH JOINT FOR PLIERS AND LIKE INSTRUMENTS Filed Jan. 27, 1950 v INVENTOR. MAX SCH/F F534 06K Patented Sept. 23, 1952 MESH JOINT FOR PLIERS AND LIKE INSTRUMENTS Max Schifibauer, Springfield, N. J.
Application January 27, 1950, Serial No. 140,930
This invention relates to pliers, and similar tools, having two main parts pivotally connected together and adapted to be operated by manipulation of their handles.
It is an object of the present invention to provide pliers and similar tools which consist principally of two' complementary parts, which are pivotally connected together in box joint fashion wherein each ofthese parts may be made from two identical forgingsyare consequently formed with one and the same die and have the same shape thereby eliminating the necessity of different or of a plurality of dies, whereby great saving is attained in time and labor.
It is a further object of the invention to provide means affording the transformation of one of said parts to a male part by simply applying and fixing to said one part a mesh plate forming projections to serve as guides which cooperate and engage recesses of the other part.
Other objects of the present invention are to provide pliers and similar tools made of like parts and assembled with a guide plate or mesh plate, conductive to simple construction, inexpensive production and minimum number of parts. This construction is durable, convenient to use and efficient in operation.
For other objects and. for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in which Fig. 1 is, a top plan view of a pair of pliers embodying the invention, the parts of the pliers being assembled together and shown in open position.
Fig. 2 is a side elevational view of the pliers of Fig. 1 with the parts closed upon one another.
Fig. 3 is a fragmentary plan view of one of the parts of the pliers with the mesh plate according to the invention tightly fitted therein.
Fig. 4 is a fragmentary plan view of the other part of said pair of pliers.
Fig. 5 is an enlarged fragmentary end view (looking from the left of Fig. 3) of the one part fitted with the mesh plate.
Fig. 6' is an enlarged fragmentary end view (looking from the right of Fig. 4) of the other part.
Fig. 7 is a fragmentary vertical sectional view taken generally along line 1'I of Fig. 2.
Figs. 8, 9 and 10 are respectively perspective views of various forms of guide or mesh plates according to the invention and which may be used in the operation of the parts of the pliers.
Referring now more particularly to the drawing Ii! and II designate complementary plier parts perforated and adapted to be pivotally connected together. The part II] has a jaw portion I2 and a handle portion I3 integral therewith and made from a single forging. The'part II has a jaw portion I4 and a handle portion I5 made from a single forging as that of part III. The part I0 is made, as shown in Fig. 4, with a fiat bearing face or portion I6 and curved undercut guide recesses I! and I8 disposed diametrically opposite each other and respectively in the jaw portion I2 and handle portion l3 of the part I0. An opening or perforation I9 extends through this bearing portion I6 of the part ID.
The part I I is formed, as shown in Figs. 3 and 5 with a bearing surface or portion 2| with substantially straight undercut recesses 22 and 23 extending respectively into jaw and handle portions I4 and I5 of the part II. These straight recesses are cut after the forging is made and are adapted to receive with press fit a guide plate 24 and particularly straight edges 25 and 26, respectively, thereof (Figs. 3 and 8). A perforation 26' is provided in mesh plate 24 adapted to register with the perforation 21 of the part II and perforation I9 of the part II].
The plate 24 has preferably curved edge portions 28 and 29 adapted, when the plate is fixed to the part II and within the recesses 22 and 23 thereof, to move into engagement with respective recesses I! and I8 of the part ID. This is effected when the parts are coupled together by pivot pin or rivet 30 extending through the registered perforations or holes of the parts I0 and I I and mesh or guide plate 24. The guide plate 24 is preshaped to tightly engage with press fit the recesses of the part II.
A positive guiding action is effected at curved edge portions 28 and 29 which enter the recesses I1, I8 as the parts I0, I! are closed upon one another to bring the jaw portions I2 and I4 thereof together. The two edge portions 25, 2B of plate 24 tightly engage recesses 22, 23 in the respective plier parts It and II. The shape and number of these edge portions can be varied, as clearly illustrated in Figs. 9 and 10.
In Fig. 9 there is shown an elevated curved edgeportion 28? on; the upper end and a diagonally disposed curved edge portion 29' on the opposite end. The edge portions of the plate 24' for engagement with the recesses of the part II as shown in Fig. 9 are indicated at 25' and 26'.
As shown in Fig. 10, the guide or mesh plate, as indicated at 24" has edge portions 25", 26" which are straight and adapted to enter respective straight recesses 22 and 23 of the part I I, but the recesses of the part It! must be altered to receive straight edge portions 28" and 29" instead oi curved edge portions. The plates 24' and 24" will be tightly fitted in part I l and in the same manner as described above and in which the plate 24 is connected to the part I I. It can be seen that by the use of the plate 24" having straight marginal edge portions, the parts 10 and I I will have the same recesses therein and can be made from the same die. The recesses of the one part will thus be the same as the recesses of the other part. This makes possible the forming of the plier parts from the same die and affords a great saving in labor expense and production cost.
While various changes may be made in the detail construction, it shall such changes shall be within the spirit and scope of the present invention as defined by the appended claims. For example, one of the guide edges of the mesh plate, say, 28, may be entirely eliminated and edge 29 may then have any desired extent and configuration.
Instead of press fit, the mesh plate may be welded in place or otherwise afilxed to one of the parts id or II by any known securing means.
It can thus be seen that there has been provided according to this invention a plier or similar tool comprising complementary parts, each of said parts having jaw and handle portions, said jaw and handle portions of'each part having undercut recesses, a guide plate having edge portions adapted to cooperate with the respective recesses of the parts and fixed to the recesses of one part, and a pivot pin connecting the plier parts and the guide plate together, and the edge portions of the guide plate being straight and inclined with respect to each other, the recesses of the respective parts being of similar contour and adapted to receive the respective straight edges of the guide plate, the plier parts thereby being of the same shape and adapted to be formed with the same die, the shape being the same even to the recesses.
Although the invention has been described with reference to a certain specific embodiment thereof, it to be distinctly understood that various modifications and adaptations of the arrangements herein disclosed may be made as may readily occur to persons skilled in the art without constituting a departure from the spirit and scope of the invention as defined in the objects and in the appended claims.
Having thus described the invention'what is claimed as new and desired to be secured by Letters Patent, is:
