NITED STATES SAMUEL G. LAWSON, OF PORTLAND, OREGON;
GLASS-TUBE CUTTER.
SPECIFICATION forming part of Letters Patent No. 333,235, dated'December 29, 1885.
Application filed July 1, 1885. Serial No. 170,360. (No model.)
To all whom it may concern:
Be it known that I, SAMUEL G. LAWSON, of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Glass-Tube Cutter, of which the following is a full, clear, and exact description.
My invention relates to implements for cutting the ends of glass tubes off squarely or for making short glass tubes or rings from longer tubes, and has for its object to facilitate the accurate cutting of the tubes by providing a simple, inexpensive, and efficient implement for the purpose.
The invention consists in a glass tube'cutter comprising two rods pivoted together, a cutting disk or point attached to the end of one rod,and a gage-plate attached to the other rod.
The invention consists, also, in particular constructions and combinations of parts of the tube-cutter, all as hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings, formingpart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a side elevation of my improved glass-tube cutter, partly in section. Fig. 2 is a side elevation of a modified construction of the cutter. Fig. 3 is an edge view of the hinge loop or clevis, and Fig. 4 is a rear face view of the gage-plate.
The letters A B indicate a pair of wire rods, which are pivoted to each other, preferably by means of a loop-plate or clevis, O, which is fixed at its bend by solder or otherwise to one of the rodssay the one Aand apivot-pin, 0, passes through the other rod, B, and opposite side plates or parts of the clevis. The rods A B may have wooden handles or halfhandles D attached at their back ends, as in Fig. 1; or the rods may be bent forward on themselves to form handles D, as in Fig. 2. In either case a spring, E, attached to one of the handles or rods will act by its free end on the other handle or rod to throw the-handles apart and carry the forward or outer ends of the rods A B toward each other. The rod A carries at its outer forward end a cutter, which may either be a hardened-steel disk, F, piv- Oted on the end of the rod, as in Fig. l, or a hardened-steel or a diamond point, G, set into the side of the end part of the rod, as in Fig. 2. In either case the operation will be the same and as presently described.
On the rod B, I place a metal plate, H, which has a slot at h, through which the rod B passes, and at or around this slot at the back face of plate H, is attached suitably an elastic metal loop-clamp, I, through which the rod B also passes, and by a set-screw, J, threaded into the loop I, the loop may be tightened on the rod B, by turning the screw'J for holding the plate H at any desired distance back of the cutter F or G, for gaging the length of the piece to be cut from the end of the glass tube K. (Shown in dotted lines in Fig. 1.) The gage-plate H also has a slot, h, through which the rod A of the cutter passes, which allows said rod to be thrown away from the rod B at its outer end. The rod B may have a notch at f, into which the projecting edge of the cutter F may enter when the outer ends of rods A B are forced together by the action of spring E.
The operation is as follows: The gage-plate H will be set on the rod B so as to stand at the desired distance back from the cutter F or G, and then secured by tightening the screw J, and the ends of both rods A B will be passed into the end of the tube K, and the handles D D or D D will be pressed toward each other, which will throw the end of rod B against one side of the tube and the cutter against the opposite side of the tube, and by holding the gage-plate H closely to the end of the tube and turning the rods in the tube by means of the handles of the rods, or turning the tube on the rods, or by both movements simultaneously, the cutter F or G will mark or cut the inside face of the tube, so its partially-severed end may readily be broken off in the usual way.
As the spring E tends to close ,the outer ends of the rods A B to each othet, the implement may very readily be placed in and removed from glass tubes of varying sizes, as will readily be understood.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. ,A glass-cutter consisting of two rods pivoted together and provided with handles, a cutter on the end of one rod, and a gageplate adjustabl'y secured to the other rod, substantially as herein shown and described.
2. A glass-cutter consisting of two rods pivoted together and provided with handles, a spring between the said handles, a cutter on the end of one rod, and a gage-plate secured to one rod and slotted to receive the other, substantially as herein shown and described.
3. In a glass-cutter, the gage-plate H, provided with the slots h h, the elastic loop-clamp I, secured around the slot h, and the set'screw J, substantially as described.
4. In a glass-cutter, the combination, with 15 side of the said plate around the slot h, and the set-screw J, substantially as herein shown and 20' described.
