(Ci. eti- 132) 3 Claims.

This invention relates to a bolt cutter and more particularly to a bolt cutter specifically designed for cutting bolts normally used in securing shank and circle assemblies as used in hanging eave spouts.

The principal object of the invention is the provision of a bolt cutter having a jaw member Y positioned for horizontal and vertical movement.

A further object of the invention is the provision of a bolt cutter having a pair of jaws, one of which is stationary and the other of which is movable, and the movable jaw arranged for horizontal and vertical movement with respect to the stationary jaw.

A still further object of the invention is the provision of a bolt cutter having a stationary and a movable jaw and a single handle for imparting both horizontal and vertical movement to the said movable jaw.

The present invention relates to a bolt cutter particularly adapted for use in cutting bolts normally securing circles and shank assemblies as commonly employed in mounting eave troughs and the like. It is well known in the art that various eave spouts which are hung from the eaves of buildings by circle and shank assemblies must frequently be repositioned to facilitate proper drainage and that in order to adjust the circle directly supporting the eave troughs with respect to the shank which the circle is nor- `mally suspended from, it is necessary to remove the bolt ordinarily securing these parts 'together'. It is also known in the art that these bolts are commonly rusted to the point where they no longer can be separated and itis therefore necessary to saw them or le them apart.

The present invention relates to a bolt cutter particularly adapted for manipulation in the area adjacent an eave trough so that the bolt securing the circle and shank assemblies to- Vvgether can be cut thereby.

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 ci construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can i be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanyf ing drawing, wherein:

Figure l is a side view of the bolt cutter with v parts in cross section, showing the same in operative relation to a circle and shank assembly.

:o 5.--5 of Figure l and enlarged with respect there- Figure 6 is an enlarged elevation of a portion of the bolt shown in Figure 1.

By referring to the drawings and Figures 1 and 16 2 in particular it will be seen that a bolt cutter has been disclosed which comprises a stationary handle le having an offset section Il and a recess !2 formed near its uppermost end and a xed blade i3 mounted partially in said recess. A hol- '.o low body member i4 is secured to the handle Ill inwardly from the uppermost end thereof as by means of rivets i5 and defines a horizontal channel for a secondary hollow body member l5 which is mounted for horizontal movement in the hollow body member I4. A portion of the secondary body member I5 depends below the hollow body member I4 and is rotatably secured to the end of a screw li which in turn is rotatably engaged in a projection I8 formed on the hollow body member lli. The secondary hollow body member it has a vertically movable jaw I9 positioned therein and the movable iaw I9 has a removable cutting blade 2U secured thereto. It will thus be seen that the removable cutting blade 2@ is disposed for lateral movement with respect to the handle ll and particularly the uppermost end thereof and the xed blade l 3 thereof.

Means for imparting vertical movement to the vertically movable jaw IS is provided and comprises a secondary handle 2l pivotally mounted by means of a pivot 22 to the depending portion of the secondary hollow body member I6 and best illustrated in Figures l, 5 and 6 of the drawlings. By referring to Figures l, 2 and 5 of the drawings in particular it will be seen that the depending portion of the secondary body member i6 that extends below the hollow body member It is positioned to one side therof and that the upper end of the handle 2l is biurcated as at 23 and positioned on either side of the depending portion of the secondary hollow body member le by the pivot 22 as heretofore mfntioned. The outermost end of the secondary handle 2| is tubular as indicated by the numeral 2G and encloses a rotatable plunger 25, the outermQst end of which is secured to a rotatable cap 26 which is slidably mounted on the tubular body 2@ for longitudinal movement and normally urged inwardly thereon by a coil spring 21.

The innermost end of the plunger 25 is provided with a squared socket 28 which is adapted to engage the squared end 29 of the screw i'l heretofore referred to. It will thus be seen by referring to Figure i of the drawings that when the secondary handle 2l is swung upwardly to horizontal position, as shown in dotted lines, and the handle 25 moved outwardly momentarily, thesquared socket 23 may be engaged on the squared end 29 of the screw il and the same revolved thereby. Thus the handle 2l serves to elevate the vertical movable jaw i9 when swung in an arc based on the pivot 22 and when in horizontal position and engaged on the squared end 29 of the screw l? to move the hollow body member I6 horizontally in the hollow body member It.

Means for imparting movement from the bifurcated innermost end 23 of the handle li is shown in Figures l and 6 of the drawings and comprises a projection having a rounded end EG engaged in an opening 3l formed in the lowermost portion of the vertically movable jaw i9. It will thus be seen that swinging motion imparted to the handle 2l will cause the projection to rise or fall in the opening 3i oi the movable jaw I9 and hence impart vertical movement thereto.

In utilizing the bolt cutter as in cutting a bolt normally securing a shank and circle, the cutter is positioned with the stationary blade i3 on the head of the bolt as shown in Figure 1 of the drawings, the bolt being indicated bythe numeral 32, and the handle 26 rotated while in horizontal position to move the secondary body member I6 transversely to bring the blade 2li into position beneath a nut 33 on the bolt 32. In such position the handle 26 is then moved outwardly momentarily to release the end of the screw il and then swung downwardly as shown in solid lines in Figure i, which motion imparts vertical motion to the movable jaw I9 and hence causes the bolt to be cut. In Figure l of the drawings the shank is indicated by the numeral 3Q and the circle by the numeral 35.

In practice, the circe supports the eave trough and the shank 3&3 is bolted thereto as by the bolt 32, and the upper portion o1 the shank positioned on the cave and secured thereto with conventional fasteners. It will thus be seen that the bolt cutter may be advantageously used for cutting the bolts normally securing these parts in assembly and thereby enabling them to be adrjusted with respect to one another for properly suspending an eave trough. The bolt cutter uti lizes the novel transverse and longitudinal action, with respect to the handle i i thereof, obtaining the desired results, It will be obvious that the various parts are mounted for proper sliding engagement with respect to one another and in a manner preventing them from binding or warping.

By referring now to Figures 2 and 5 or" the drawings, the interengagement of the several parts may be seen. For example, it will be observed that the hollow body member ift provides a track-like support for the secondary body member l which is positioned therein for horizontal movement thereon. rEhe secondary body member l provides a track-like support for the vertically movable jaw le. It will be observed that the jaw I9 has anges 36 formed vertically thereon which overlie the front edge portions of the secondary body member i6, while the secondary body member I6 has horizontal iianges which overlie the upper edge of the hollow body member I4, and flanges which underlie the lower edges of the hollow body member I 4. Thus, each of the two movable members l5 and i9 are movably held by interengagement against rocking 0r tilting motion and the tool thereby rendered effective.

By referring to Figures 3 and 4 of the drawings detailed views of the cutting blade portions of the bolt cutter may be seen. Figure 3 illustrates the formation and positioning of the blade i3 carried on the upper end of the handle Il and in the recess l2 thereof, it being observed that the blade I3 is removably afxed to the tool by means of a screw 31. It will also be observed that the lower edge or cutting edge of the blade I3 is arcuate, as indicated by the numeral 38, so as to be self-centering with respect to a bolt over which it is positioned. In Figure 4 of the drawings the vertically movable jaw I9 is shown together with the replaceable blade 20 which is secured thereto by a pair of screws S9, it being observed that the cutting edge of the replaceable blade 2l) is arcuate, as indicated by the numeral 6U, to make it self-centering with respectk to a bolt to be cut.

It will thus be seen that the bolt cutter disclosed herein may be efficiently used for quickly and easily cutting a bolt such as the bolt 32 shown in Figure 1 of the drawings which normally are used to secure the shank and circle assemblies from which eave troughs are supported on building eaves.

It will be obvious to those skilled in the art that the bolt cutter disclosed herein meets the several objects of the invention.

Having thus described my invention, what I claim is:

l. A bolt cutter including a longitudinally extending Xed jaw having a cutting blade mounted thereon and a movable jaw having a cutting blade mounted thereon, sidewardly extending support means aiXed to the Xed jaw for movably supporting the movable jaw, said support means including a movably disposed body member, the said movable jaw being mounted for parallel movement with respect to the fixed jaw and the said movable body member being mounted for lateral movement with respect to the Said Xed jaw.

2. A bolt cutter comprising an elongated body member having a blade positioned inwardly from one end thereof, a hollow body member ailiXed to 'the said body member and at right angles thereto, and a secondary body member slidably mounted on said hollow body member and a movable jaw disposed in said secondary body member, and a cutting blade formed on the said movable jaw, lever means pivoted on the said hollow body member for imparting movement to the said secondary body member and screw means on the said secondary body member for imparting movement to the said movable jaw whereby the said blade affixed thereto may be moved into proximity to the blade formed on the said body member.

3. A bolt cutter comprising an elongated body member' having a recess formed in one end and a blade mounted partially within the said recess, a bifurcated sideward extension on the said body member and a secondary body member slidably mounted on said bifurcated extension, and a mov- 5 able jaw slidably mounted in said secondary body member and at right angles to the said bifuroated extension, a handle pivotally secured to said seeondary body member and a projection on said handle and engaging the said movable jaw for imparting movement thereto, a screw threadably engaging a portion of the said bifurcated body member and rotatably secured to the said secondary body member, and a socket formed on the said handle for removably engaging the said screw, the said handle being rotatably mounted.

so that the screw may be revolved thereby and the secondary body member moved thereby.
