COMBINATION CUTTER. AND VISE.

Application filed May 12, 1928.

My present invention has reference to a combination vise and cutter for soil andwater pipes. I

The primary object of the invention is the provision of a device for this purpose by whose use a pipe will be held in a vise and will be operated on by cutter wheelscarried by a member that has a track engagement with the vise whereby the pipe will be firmly held and effectively out without danger of cracking the pipe or leaving the same with a jagged edge.

A further object is the provision of a device for this purpose in which the cutter wheels are sustained in proper alinernent and adjusted in an easier manner to the pipe being cut thereby.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when. read in connection with the accompanying drawings which form part of the application with the understanding, however, that the improvement is capable of extended applicationand is not confined to the exact showing of the drawings nor to the precise construction de scribed and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawings;

Figure 1 is a top plan view of tlieimprovement.

Figure 2 is a side elevation thereof.

Figure 3 is a sectional view onthe line 3-3 of Figure 1.

Figure 4 is a sectional view approximately on the line 4-4 of Figure 1.

Figure 5 is a detail sectional view approximately on the line 55 of Figure 1.

Figure 6 is a view looking toward the inner face of the cutter member.

Figure 7 is a view looking toward the inner face of the vise member. s

Figure 8 is a view looking toward the outer face of the vise member.

Figure 9 is a perspective view of the latch.

The ordinary method employed for cutting a soil pipe is that of a hammer and a cold chisel. This method very often cracks the pipe and almost invariably leaves a jagged edge. With my improvement it will be noted as the description progresses that the pipe is effectively gripped and is operated upon by a rotary cutter so'that the liability of cracking 'ter member of the improvement.

Serial No. 277,301.

the pipe and likewise the liability of leaving the out pipe with a jagged edge is effectively overcome.

As disclosed by the drawings the improvement comprises two members or sections,one in the nature of a gripping member or vise and the other in the nature of a cutter.

In the showing of the drawings the Vise member is made up of two ring segments 1 and 2, respectively, the said segments being centrally connected by a pivot 3. Each of the segments or sections is provided with openings or pockets in which there are received vise or gripping members 4, the said members being retained in their pockets by removable. means such as pins 5. By reference to thedrawings itwill be seen that the toothed edges oflthe gripping or vise members 4 project into the. area of the ring comprising the members 1 and 2, and likewise by reference. to'the drawingsit will be noted that each of the sections 1 and 2, on their .side or end oppositetheir pivotal connection are formed with outwardly extending spaced ears 6 and 7 respectively. Also by reference to the drawings it will be noted that the outer periphery of the section 2, at a suitable distance from the end thereof which contactsor is received in the section 1 is formed with a depression 8. In addition to being provided with a depression the section 2'has on its outer periphery, and extending from one of its sides an enlargement in the natureof a rim 9.

There is designed to be received in the depression 8 the reduced and non-threaded end 1001 a threaded stem 11, whose outer end is provided with a handle. This stem is screwed through a block 12. The block 12 is provided with oppositely extending ears 13, respectively and through one of these ears there is pivoted a link 14 which is likewise pivoted to the ear 7 on the section 2. The second ear 13 has pivotally connected therewitha meniber15 whose outer end is formed with a hook 16, and this hook is designed. to engage with a pin 17 that passes through a slot in the ear 6.

What I will term the inner face of the vise member has its sections formed with rails that provide a track. These rails are substantially U-shaped. and the outer element ofeach of the rails, is indicated by the numeral 18. Therails 18 are designed to coengage with substantially U-shaped rails 19 provided by segmental plates which are fixed on wh at I will term theinner face of the cut- The cooperating rails provide the vise member and the cutter member with a track whose purpose will presently be apparent.

The cutter member is also in the nature of a ring, but is preferably made up of tour pivotally connected sections 20, respectively. Each of the sections has an opening or pocket 21 therethrough, and in each pocket there is secured by a removable pivot 22 a wheeled cutter 23. One of the sections 20 is formed with a depression 2% similar to the depression 8 in the vise member, and this sect-ion, and the section adjacent thereto is formed with outwardly extending cars 25 and 26, respectively. The depression 24 is designed to receive therein the reduced and non-threaded end of a'threaded stem 27, similar to the stem 11. This stem has an outer handle. The said stem is received through a block 28, similar to the block l2. The block 28 has its opposite sides formed withoutstanding ears 29, respectively, and to one of these ears 29 and to'the ear 25 there is removably pivoted a link 30. To the second ear 29 there is pivoted a link 31 that has its free end formed with a hook 32. This hook is designed to be swung into a recess in the ear 26, and to en gage with a pin 33 that passes through the said ear.

The ear 26, on its outer face is provided with spaced lugs 35 and between these cars there is pivoted a latch member 36 best illustrated by Fig. 9 of the drawings. The latch has a handle end 37 and its second end is provided with an angularly disposed finger 38 and this finger is designed to be received through a notch or depression 40 in the car 26, so that the finger of the latch will engage with the outer edge or the hook 32 and hold the said hook in engagement with the pin 33.

A spring 41 inliuencesthe latch to bring its latching end or finger 38 into such engagement. V

The operation of the improvement may be briefly described as follows: The latch 36 normally holds" both the sections of the vise member andthe sections of the cutter members closed, thesections of the vise member being prevented from spreading by the interengaging rails 18 and 19 that afiord the track. The latch member, is moved to bring its finger out of the notch 40 to permit of the hook member 31 beingswung to the dotted line position in Figure 6 and likewiseto permit of t e hook member 16 being swung out of engagement with the pin 17. The sections or segments providing the vise and the cutter may now be swung away from each other and the device inserted over the pipe to'be cut. The vise member is next closed and the handle ofthe stem is operated The sections or segments of the cutter mem ber are now closed and the link carrying hook is swung to engage with the pin 33 and is latched in such engagement. The cutter member, through the instrumentality of the handie on the stem 27 is imparted a reciprocatory movement in a rotary direction, and the stem is adjusted to advance the wheel or rotary cutters 2-3 during the cutting operation. During this operation the handle of the stem 11 of the vise is held stationary, and the handle of the cutter member may be turned only suiiiciently to impart a one fourth revolution to the ring comprising the cutter. The rim 9 acts as a retainer tor the assembledcutter and viseand also serves as a rest for the vise section to permit the cutter sections to be rotated without interference.

The rim 9 also serves as a rest for the cut ter when a horizontally arranged pipe is being cut and which pipe is close to the ground, the said rim resting on the ground surface and, therefore, sustaining the vise proper from such contact.

-Having described the invention, Iclaim:
