FREDERIC H. MOORE AND NATHANIEL D. WHITNEY, OF BOSTON, MASS.
IMPROVEMENT IN THREsHoLDs.
o Specication forming part of Letters Patent No. 155,807, dated October 13, 1874 application filed July 24,1874.
To all whom it may concern:
Be it known that we, FREDERIC H. MOORE and NATHANIEL D. WHITNEY, both of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Door-Threshold, of which the following is a specification Our invention consists in improving a doorthreshold (more especially an inside doorthreshold) by making it in the form of a rod, and placing it above and upon the iioor, di` rectly beneath the door when closed, and also in fastening it, preferably at each end, in such a manner that it can be removed at will.
The thresholds in ordinary use are generally l made of wood or marble, permanently attached to the lloor, and of a width which embraces the whole of the door-jamb. They are liable to scratch by wear, and become unsightly, requiring constant care and attention to keep them in order; whereas our threshold `can be readily removed for cleansing, and, from its small size, is scarcely perceived when'the door is closed, as the carpet or floorcovering is carried quite up to the threshold on either side. It has little surface to wear, and will last a long time before any abrasion can be perceived.
We prefer to make the threshold round and of metal; but it may be of other forms, or 1ionade of other materials, such as wood or rub- In the drawings, we have shown several methods of securing our threshold to the floor, those being the best that have occurred to us 5 but other Ways may be adopted.
Figure 1 shows a cylindrical rod, A, running across the door B from one door-jamb, C, to the other, O.
Figs. 2, 3, and 4 show a rod where a portion of its end at O is cut away to allow of its being tted to a recess, a, cut in a plate set in the door-jamb, the end at G being fitted with a spring-spindle, d, entering the jamb, and a retractingpin, c, operating through a groove cut in the side of the rod. The spring may in some cases be dispensed with, and only the spindle used, with the retracting-pin. This device operates by locking the end of the rod A into the recess a, and locking the spindle cl into the jamb C.
Figs. 5, 6, and 7 show a method of locking the rod when its end at O enters the jamb, and the spring-spindle afterward forces the other end into the jamb G and holds it there.
Figs. 8 and 9 show another mode of locking the rod, where a clasp, g', is pivoted to the jamb, and embraces the top of the rod, the friction of its end against the side of the rabbet holding it in place.
Fig. 10 shows at m a hinged clasp, which, when turned up, releases the rod, 4and when turned down holds it firmly.
Figs. l0 and 11 show methods of fastening the center of the rod by means of grooves and pins k, should it ever be found necessary to prevent them from springing; but a groove in the floor will generally answer the purpose.
We claim as 'our invention- The rod A, in combination with the jambs C C and the lioor, substantially as described.
