IMPROVEMENT IN CAM-BOLTS FOR FASTENING DOORS.
Specification forming part of Letters Patent No. 179,649, dated July 11, 1876; application filed the jambstop.
Thenature of myinvention consists in an annular cam pivoted eccentrically to an ordinary lock-case by a knobbolt, and arranged so that by its gravity it will be held in the case or in the catch, as required.
In the drawings, Figure l is a side elevation of the cam in its case, one plate of the latter being removed to show the cam more clearly Fig. 2, an edge view of the cam in its case; Fig. 3, an edge view of the cam in the catch-plate.
A represents a cam-plate, which is fitted to turn in a case, E F Gr,and is hung eccentrical- 1y on a spindle, B, so as to remain by its gravity in the case, or remain projected out of the case, as when fastening a door, as shown by dotted lines A. The cam part proper is described by a line from O to I), and its construction is such that the thin part D of the cam first catches on the plate I, and as the knob'H is turned in the right direction the thicker part of the cam is wedged into the slot in the catch 1, and, consequently, forces adoor, to which the case E F Ur is attached, closely to thejambstop ot' a door-casing. The device is designed more especially to be used for ice-house and refrigerator doors; but it. is
December 18, 1875.
serviceable in holding any door tightly in its casing, keeping out air, and preventing rat tling and jarring.
I do not claim, broadly, a cam as a tightener; but confine myself to the combination.
In applying the device, the case E F G is tobe fastened to a door similarly to the present mortise lock or catch, and the catch-plate I is to be fastened to a jamb-casing in the same manner as for a spring catch-bolt.
The operation is to turn the knob H in one direction to lock the cam, and turn it in another direction'to unlock it.
It will be observed that the position ofthe cam, as shown by dotted lines A, is such that its lower edge strikes the shoulder J of the bottom ofthe faceplate. This is important in governing the movement of the cam in that direction. It is also important that the cam when in the case has a stop against its plate F, as shown in Fig. 1, that its extreme movements may be controlled.
Any suitable lock metal can be used in the manufacture of the device.
I claim and desire to secure by Letters Patent- The cam A (I D, eccentrically hung to the spindle B, and combined with the caseE F G,
having a stop at J on the face-plate E and against the inside of plate F, and held in either position against such stops by its gravity, as and for the purpose set forth.
