DOOR, COMMODE, &c., KNOB
Specification of Letters Patent No. 98, dated December 2, 1836; Antedated September 2, 1836
To all whom it may concern:
Be it known that we, ENOCH ROBINSON and FRANCIS DRAPER, both of Cambridge, in the county of Middlesex, Commonwealth of Massachusetts, and JOSEPH H. LORD, of the city of Boston and Commonwealth aforesaid, trader, have invented and put in use a new and useful improvement in the manufacture of door, commode, furniture, and other knobs by which the knob is securely fastened to the plate or socket without any spindle or screw being inserted into the knob and which we call our “socket-knob,” which said invention is specified by us as follows, towit:
This improvement consists of a combination of the common knob, having a neck or shank between, and smaller than the head, and foot of the knob, with a socket or plate either made wholly or having an edge or ring made of some soft metal capable of being set around the foot of the knob by turning in a lathe or otherwise without the application of heat. This socket is cast or otherwise made with a face, corresponding in form to that of the foot of the knob, and with a perpendicular edge or ring of soft metal around the outside of a depth somewhat greater than the thickness of the foot of the knob, the foot of the knob is then to be inserted into the cup, thus formed by the face; and edge or ring of the socket, and the edge or ring is then to be turned down and let either in a lathe or otherwise close around the foot of the knob above the largest part of the foot so as to confine the knob closely and securely to the socket, or plate. If the use of the knob requires it, it may be made more secure from turning in the socket, by fitting the foot of the knob and the face of the socket together by a corresponding projection in the one and depression in the other, or by making the foot of the knob of some angular form with a corresponding hollow in the socket in the manner already practiced or otherwise.
We do not claim as our invention the knob properly so called, but admit that it has been known, and used before in the form mentioned, nor do we claim any part of the socket or plate except the edge or ring of soft metal after it is turned down, and set as aforesaid around the foot of the knob as a new means of combining the knob, and the socket; but our invention and improvement consists in
The combination of the knob with the socket by means of the said edge or ring of soft metal when turned down, and set around the foot of the knob, and we claim nothing more.
The said parts and the socket knob, when completed will be more fully understood by reference to the annexed drawing, in which-
No. 1, is the socket before the knob is inserted, No. 2, is the knob, and No. 3, is the socket knob after the same is finished, and ready for use.
In testimony that the foregoing is a true specification, and description of our said improvement, we have hereunto set our hands this twenty-second day of June in the year of our Lord one thousand eight hundred and thirty-six.

Door Spring
UNITED STATES PATENT OFFICE.
THOMAS THORPE, OF WEST CAMBRIDGE, MASSACHUSETTS.
DOOR-SPRING.
Specification of Letters Patent No. 506, dated December 7, 1837.
To all whom it may concern:
Be it known that I, THOMAS THORPE, of West Cambridge, county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Door-Springs. The said improvement, the principle thereof, and modes in which I have contemplated the application of the same, together with such parts, combinations, or characteristics by which it may be distinguished from other inventions, and which I claim I have fully set forth in the following specification and drawings referred to herein.
A. A represents the outer casing of brass, or other suitable metal, shaped as seen in the drawings, or otherwise properly formed.
B is the door on which the spring is to be fastened; C, the door frame.
E is a metallic rod, turning on a hinge at a, in the side of the piece of metal F, screwed to the door frame. The rod E passes through holes in the ends b, c of the casing A, moving freely back and forth in said holes.
G is a cross bar, attached to the rod E in a proper manner, and has connected to each extremity the end of a wound spring, H H, whose opposite end is confined to the end b of the casing, or to a pin d, passing through the sides thereof.
When the door is opened, the spring H H are extended by the movement of the rod E through the slots in the ends b, c of the casing, and on withdrawing the force applied to open the door, the springs contract, and immediately close the same.
Instead of two springs, I may use only one, or I may employ three or more, should it be deemed advisable.
The main advantage of this spring consists in the exertion of a strong force to close the door, when nearly shut. Other kinds of door spring generally fail in this part of their operation.
I claim as my improvement-
The above arrangement of springs acting on a rod E, and operating in manner above described.
In testimony that the above is a true description of my said invention, I have hereto set my hand this ninth day of November, in the year eighteen hundred and thirty seven.
THOMAS THORPE.
