PLIERS.

Application led August 28, 1926. Serial No. 132,151.

One object of.t this invention is to,.provide a tool which wlll combine the advantages of a pair of round nosed pliers, a pair Aof flat 1 jawcd pliers, and a pair of side-cutters.

Another object of the invention is to provide a pair ot' pliers which will bc peculiarly effective in holding round objects without marring them, it being possible to hold ob' jects of different diameters, with the handles 10 of the pliers spaced at. about the same distance apart, thereby keeping thc handles of the pliers close enough together so that they can be gripped readily.

It is Within the province of the disclosurerto improve generally and to enhance the utility of devices of that'type to which the invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in side elevation, a pair of .pliers constructed in accordance with the invention;

Figure 2 is an elevation wherein the pliers are vlewed edgewise; .Figure 3 is a view similar to Figure 2, parts being broken away and parts being Figure 4 is a diagrammatic cross sectional view illustrating how the tool is used in holding round objects; and

Figure 5 is a frau-mental side elevation, the opposite side of the tool appearing from that which vis shown in Figure 1.

In carrying out the invention there is provided a pair of pliers comprising pivotally connected handles 4. Each handle 4 is provided with a first jaw 1 and with a second ljaw 2. The 'aws 1 and 2 are located side by side, as s own in Figure 4. The

first jaws 1 are of polygonal cross section and are disposed opposite. to each other. The second jaws 2- are of approximately circular cross section, to provide curved surfaces 3 thereon. The second jaws 2 are disposed opposite to each other. The first jaws have pronounced inner longitudinal edces 5. The edges 5 of the-jaws v1 cooperate with the. curved surfaces 3 of the second jaws 2, to hold an object 6. The cylindrical surfaces 3 serve to engage the object 6 without marrin' it; Each of the second jaws 2 is in the lorm of a cone, and one element 7 of each cone forms an acute angle 8 with re- 'spect to one of the inner longitudinal edges 5 ofthe first jaws 1, the word element being used in its mathematical sense. The construction last above described is such that objects of different diameters may be held in the position of Figure 4, without changing the distance between the handles, and the handles are always at the right distance apart so that they can be gripped and held conveniently. The handles 4 are crossed on each other, as at 10, and the pivot element which connects them `is marked by the numeral 11. The portions ofthe pliers which carry the jaws l may be provided with cooperating cutting edges 12, giving the tool all of the advantages of a side cutter.

I claim Apair of liers comprising pivotally connected hand es each provided with a first jaw and with a second jaw, located side by side, the first jaws being of section and belng disposed opposite to each ,other, the second jaws being vof approximately circular cross section to provide curved surfaces thereon, the second jaws bepolygonal cross" ing disposed opposite to each other, the first l ljaws"l having pronounced inner longitudinal edges which cooperate with the curved surfaces'` of the second jaws to hold an object, thesaid c lindrical surfaces serving to enga e an ogject without marring it, the secon jaws each being in the form of a cone, and one element of each cone forming an acute angle with respect to one of said inner longitudinal edges of the first jaws, there by to enable the holding of objects of different diameters without changing the distance between the handles.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa-
