Description
RHODOLPHUS KINSLEY, OF SPRINGFIELD, MASSACHUSETTS. y
LATCH.
Specification of Letters Patent No. 5,225, dated August 7, 1847.
T0 all whom may concern:
Be it known that I, RHoDoLPHUs KINSLEY, of Springfield, inthe county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Mortise- Latches or Lock-Cases, and that the following is a full, clear, and eXact description of the principle or character which distinguishes it from all other things before known and of the manner of making, Vcon-- structing, and using the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view of a mortise latch, with my improved case; Fig. 2, a plan with the cap of'the case removed; and Figs. 3 and 4 cross sections taken at the lines (a, a) and (b, b) of Fig. 2, looking in the direction of the arrows.
The same letters indicate like parts in all the figures.
The method of making the cases of mortise latches, &c., for which I now claim Letters Patent is an improvement on the mode secured to me by Letters Patent bearing date the seventh day of March in the year 1846, and consists in making it in the form of two parallel cylinders united together by a plane which takes from each cylinder about one eighth of its circumference, instead of forming it as under my former patent, by the union of three cylinders, so that a case of about one inch in width can be inserted without mortising by simply boring two parallel holes that run into each otherw-thus vmaking a latch with a tumbler lever of nearly an inch in length with a case lof only half an inch in thickness that can belet into a door by simply boring instead of mortising as was the practice prior to the date of my before recited patent, the bar of the bolt working mainly in one of the cylinders, and the helical spring, which projects the bolt in other cylinder, and the bridle or stirrup of the bolt on which the lever or tumbler of the spindle works and which requires considerable thickness of metal also working in the two hollow cylin-y ders while the other parts of the bar ofthe bolt are made thinner to workin between the two plates where the two cylinders run into each other.
In the accompanying drawings (a) reprey gles. It is composed of Itwo plates'one cast with the front plate andthe other constituting the cap which is secured by a screw (c). The form of this case is that of two parallel cylinders united by a chord which cuts off about one eighth of the circumference of each cylinder, except for about half an inch at (d) toward the front plate, where the two cylinders are united by parallel tangent lines to leave ,suiiicient room within this part of the case to receive the head of the latch bolt when drawn back. The form of the inside of the case is substantially similar to the outside and to this are fitted the bolt (c), tumbler (f) and helical spring (g). The head of the bolt is made in the usual form, and the bar (j) is larger on one side than the other, the larger side being fitted to slide freely within one of the cylindrical cavities of the case, the size of which admits of giving to the bar the requisite strength, and the other side is much smaller to lie and slide by the side of the helical spring (g) which is attached to it and to the case and which lies in the other cylindrical cavity of the case. The rear end of the bolt is formed into a bridle or stirrup to embrace and slide on the hub of the tuinbler. The bar of the bolt along its whole length is reduced in thickness to fit that part of the case where the two cylinders are unit-ed and the sides of the bridle or stirrup are fitted to the cylindrical cavities and can therefore be made of sufficient thickness to have the required strength, and to have two shoulders (i, on which the arms ofthe tumbler act/to retract the bolt; The hub of the tumbler has its journals fitted to, and
.side so that the requisite thickness of metal can be given to make good bearings. The
ends of the hub are curved to correspond tok the curve of the outside ofthe case.
From the foregoing it will be evident that this plan of forming the case. and bolt is applicable to a mortise lock as wellas to a latch by forming the bolt lock in the same manner and providing it with the requisite tumblers, &c.
What I claim as my invent-ion and desire to secure by Letters Patent isj Making the;`case kof mortise latches or locks in the form of tWo cylinders united axis of the two cylinders composing the and running into each other, the chord form of the case, in the manner'and for the Where the two cylindrical forms are united purposeV described. being less than their diameter, substantially RHODOLPHUS KINSLEY.
as described, when this is combined With the Witnesses: bolt arranged with its greatest Width in a C. W. M. KELLER, plane passing through or parallel with the A. P. BRoWNE.
