UNITED STATES PATENT OFFICE.
SAMUEL IIOUGK, OF SPRINGFIELD, OHIO.
WlCK-TRIMMER.
SPECIFICATION forming part of Letters Patent No. 417,031, dated December 10, 1889. Application filed dune 6, 1889. Serial No. 313,339- (No model.)
To (0M whom it may concern.-
Be it known that I, SAMUEL M. HOUCK, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in VVick-Trimmers, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in lamp-wick trimmers; and the invention consists, essentially, of two bars pivoted together and forming each at one side of the pivot suitable handles and at the other side of the pivot suitable jaws, which respectively carry a straight-edged and a serrated-edged blade, which act in conjunction with each other; and the invention further consists in providing an adjustable pivot for the device, so that the jaw carrying one blade may be adjusted to move such blade nearer to the other blade, so that they will properly lap each other when they are in cutting position; and the invention further consists in placing the handles well to one side of the blades, so as to place the blades in a horizontal position across the lamp-wick without raising the hand so high; and the invention further consists of certain details of construction hereinafter fully specified.
In the accompanying drawings, forming a partof this specification,and on which like reference-letters indicate corresponding parts, Figure 1 represents my improved lan1p-wick trimmer in side elevation; Fig. 2, an edge view thereof; Fig. 8, a sectional view on a larger scale; Fig. at, a detail perspective view of the serrated blade, and Fig. 5 a detail perspective view of the pivot-block.
The letters A and B respectively designate two bars of metal formed into handles 0, nor mally distended or held apart by the interposition of strips D, of resilient metal, secured to the handles and opposing each other near the center, as shown. These bars are each mortised about one-half their thiekiiess and lapped across each other, as usual in 0011- structing pinehers and pliers, and the bar A is provided with a slot E, to which is slidingly fitted the shank of the pivot-block F. A pivot-screw G passes through av hole in the bar B and screws into the pivot-block F, as shown in dotted lines in Fig. 3. The pivotblock is adjusted back and forth in the slot E by means of an adj Listing-screw I-I, mounted in the head of said block, and rotatably but non-slidingly connected with the bar A by fitting an opening therein and receiving a pin I in an annular groove J formed in the each of two members K K, extending from a and forming a part of the bar A, and of members L L, extending from and forminga part of the bar To the members K is secured, by screws M or otherwise, a blade 0, having a straight cutting-edge and shouldered so as to more snugly fit against the members K. To the members L is secured a serrated blade P. The inner side of the blade 0 is formed on a straightline, and .the outside of the blade P is formed in the are of a circle from the pivot center. The result is that when the handles C O are brought together the blades pass each other in close contact. The blade 0 is beveled from the outside and the blade P from the inside, as seen in Figs. 1 and 4, the serrations being beveled on the inner side, as seen in the latter figure. The result is that the two sharp edges overlap each other in intimate contact when the jaws are brought together, while the serrated form of the out ting-edge of the blade P gives it a draw out, which is of marked advantage in manipulating the device. The blade 0 may be adjusted nearer to the blade P in a radial direction by removing it and drawing a file across the ends of the members K; but the preferred means of adjusting the blades with respect to each other is that already described, through the manipulation of the screw H. Stops Q are provided to prevent the hand from slipping too much toward the pivotal point when manipulating the device.
In order to avoid the necessity of having position, while the handles are still inclined to accommodate the then position of the hand. I contemplate sometimes constructing the device with a fixed pivot between the bars,
' instead of the adjustable screw herein described.
Having thus fully described my invntion,
What I claim as new, and desire to secure by Letters Patent, is
1. As an improved article of manufacture, a wick-trimmer consisting of bars forming handles and jaws and pivoted together at a point between such portions, a straight-edged blade carried by one jaw with its cutting-edge substantially in line with the pivot of the bars, and a serrated-edged blade carried by the other jaw and arranged with its cutting end along which the serrations are formed in substantial alignment with said pivot.
2. As an improved article of manufacture, a wick-trimmer consisting of bars forming handles and jaws and pivoted together at a point between such portions, one bar being slidingly connected to the pivot,'a straightedged blade having its inner side straight and beveled from the outer side, carried by one jaw, and a serrated-edged blade curved on the outer side and beveled from the inner side and carried by the other jaw.
3. As an improvedarticle of manufacture, a wick-trimmer consisting of bars forming handles and jaws, a block carried by one bar and adjustable with respect to the other bar,
and an adj usting-screwfor adjusting the block back and forth, and a pivot passing through the other bar and connecting with said block, and a blade carried by each jaw and co-opcrating with each other to effect a cutting action when the handles are forced toward each other.
4. As an improved article of manufacture, a wick-trimmer consisting of bars forming handles and jaws, a pivot-screw fitted to one bar, a slot in the other bar, a block slidingly fitted to said slot, and an adjusting-screw engaging with the block and rotatively connected with the slotted bar, and a blade carried by each jaw.
5. A blade for a wick-trimmer, consisting of a plate provided with serrations at one edge, the serrations being beveled on their inner side and curved on the outer face or surface which works against the opposing blade, substantially as shown and described.
6. As an improved article of manufacture. a wick-trimmer consisting of two bars pivoted together and forming handles at one side and jaws at the other side, the jaws being arranged so that those of one bar are in the same plane as those of the other bar, a blade secured to one of said jaws and beveled at its cutting-edge on the outer side, and another blade secured to the other jaw and beveled at its cutting-edge on the inner side, the said plates having their cutting-edges dis posed crosswise to the handles.
In testimony whereof I affix my signature in presence of two witnesses.
