SPECIFICATION forming part of Tletters Patent N 0. 788,950, dated May 2, 1905.
Application iiled January 16, 1904. Serial No. 189,314.
To {t/ whom it may concern:
Be it known that I, HENRY B. SARGENT, of the city and county of New Haven, State of Connecticut, have invented a new and useful Improvement in Door-Holders, of which the following is afull, clear, and exact description when taken in connection with the accompanying drawings, which form a part thereof, and in which- Figure l represents a front elevation of a door-holder embodying my invention; Fig. 2, a rear View7 of the same; Fig. 8, a longitudinal section on lines 3 3 of Fig. 1; Fig. 4, a similar view with the plunger shown in its protracted position; and Figs. 5 and 6, detailed views, in front and side elevation, of the clamp.
In all figures similar letters of reference represent like parts.
This invention relates to door-holders; and it consists in the utilization in a door-bolt of an angular clamp one end of which is rigidly Vsecured to the casing and the other end of which is adapted to bind on the plunger of the bolt to limit its longitudinal movement. Hitherto where clamps have been employed in holders of this character the clamps have been fulcrumed in the casing, and an additional spring' or springs are necessary to hold the clamp in its normal position, and these springs are often broken or lose their tension.
The object of this invention is the production of a novel and eflcient holder having a minimum of parts by the employment of a clamp of this character without the use of springs and having the variousimprovements and combinations of parts set forth and claimed hereinafter. v
Referring to the drawings for a more particular description, the parts designated by the letter A represent the casing of the holder, which is adapted to be secured to a door or other object by means of screws through screwholes c or by other suitable means.
B is the plunger, herein shown as a rod, extending upward through an opening c in the top of the casing and having a foot-plate bat its upper end. Its lower end is yieldingly connected in well-known manner to a cylindrical socket L', carrying a rubber tip b2.
C is a plate rigidly mounted on the plunger B, and D is a coiled spring surrounding the plunger and having one end bear on the plate C and its other end on an internal ange c2 in the casing A.
E is a clamp formed of an angular plate of steel or other suitable material, having its Lipper end secured to the casing A by rivet e or in other manner. The lower portion of said clamp E is provided with a perforation F, slightly larger than the diameter of the plunger B, and through this perforation Fthe plunger is adapted to project, as shown particularly in Figs. 3 and 4C. The end Cr of the lower portion ofthe clamp extends through a slot c3 in the front of the casing A and forms a convenient instrumentality for operating the clamp. When the clamp is in its normal position, its lower portion lies in a position somewhat off the perpendicular to the plunger, and therefore the edges of the perforation F bind on the plunger B and prevent its longitudinal movement therein; but when downward pressure is brought to bear on this portion either on the projecting end Cr of the clamp E or through the plunger B, owing to the flexibility of the clamp, it is swung to a position more nearly perpendicular where the edges of the perforation Fdo not bind on the plunger B, so that the plunger is free to move longitudinally through the perforation. On the other hand, any upward pressure on the plunger and through it on the lower portion of the clamp will throw it still further from the perpendicular and cause the clamp to bind still more effectively.
The operation of the device is as follows: Then it is desired to operate the holder"power is applied to the plate of the plunger, and the plunger is forced downward against the tension of the spring l) as the clamp is swung away from its normal position by the downward pressure exerted on the plunger. The rubber tip then bears on the floor or other object to hold the door in the desired position. To retract the plunger, it is only necessary to exert pressure on the projecting end Cr to rswing the clamp so that the edges of the perlfPoration F will not bind on the plunger, when the springD will cause the plunger and associated parts to fly back to their normal position.
Having now described my invention, what I claim, and desire to secure 'by Letters Patent, isy In a door-holder, the combination with a casing; of a plunger capable of longitudinal movement therein; a spring normally holding said plunger against protraction; means for protracting said plunger against the tension of said spring; and a clamp of angular form, one part of which is formed ot' resilient material and has one end rigidly secured to said casing, and the other part of which extends substantially at right angles to said plunger, and is provided With a perforation through which said plunger projects, so that said clamp will normally bind on said plunger to prevent its retract-ion, substantially as described.l
In Witness whereof I have hereunto set my hand on the 13th day of January, 1904.
