siencmzohmonrofmni part of Letters Patent No. 744,552idated November 17, 1903. Applicatien filed November 29, 1902. Serial No. 133,294. (No model.)
being had to the accompanying drawings, and
to the figures of reference marked thereon, which form a part of this specification.
' Our present invention relates to doorsprings, and more particularly to'that class of door springs known as lever door- The object of our invention is to provide an improved spring which caii be 'so adjusted as to close or open the door to which'the same is applied and which is capable also of adjustment to retain the door atany interme-' diate point in its'rotation', whether'the spring is set to open or to close the same or whether the spring is untensioned.
Further objects of ouririvention are to pro-f vide many improved details of structure fully described herein and shown in the accompanying drawings, in which like reference-numerals refer to like parts, and in 'which- Figure 1 is a view of our improved lever door-spring, showing a portion of a door to which the same is applied. Fig. 2 is a top view of the same, showing in dotted lines our device adjusted to retain the door at an angle of forty-five'degrees to the doorsill when the spring is set to close the door.- Fig. 3 is a detail View of the spring-casing and the parts carried thereby. Fig. 4 is a vertical circular casing 3, open in the rear thereof, having a perforated top and bottom and being also providedwith a peripheral slot 4 of suitable length at the base thereof.
5 is a spindle, the lower end of which passes through the perforation in the bottom of the casing 3. The spindle 5 is provided with a squared shoulder 6 and an annular flange 7 above said shoulder 6. (See Fig. 4.) The flange 7 fits loosely in the perforation in the top of the casing 3. At the top of w the spindle 5 is a perforated head 8, (see Fig. 5, dotted lines,)
adapted to receive the lever 9, which may be secured against movement in the head 8 by the set-screwlO. Keyed at its upper end onto the squared shoulder 6 of the spindle 5 ma drum 11, having an annular flange 12 (shown in section, Fig.4) at its upper end and seating at its lower end 'on a ratchet-wheel 13, loosely mounted upon the spindle 5 near the bottom of the casing 3. The ratchet-wheel 13 is provided with a thickened central portion or hub 14, which fits loosely in the mouth of the drum 11 and acts as a guide to hold said drum 11in place. Surrgunding the drum 11 is a spiral spring 15, the lower end ofwhich is secured in perforation16 in the ratchet- 'wheel13 and the upper end of which is secured in a like perforation 17in the flange 12 of the drum 11.
The ratchet-wheel 13 is capable of revolu- Pivoted on the spindle 5 between the wheel 13 and thebottom of the casing'3 opposite on its pivotal swing, at which point it engages said teeth through the slot 4.
20 is a projection or bracketcast on the bottom 'ofthe casing i3. Pivoted to the bracket 20 is a dog 21, which engages the teeth of the wheel 13 on either side of its pivotal point through the slot 4.
The outer end of the lever 9 passes through a collar 22, sustained by the lever within a bracket 23, screwed to the door 2. The lever 9 passes through a slot 24 in the bracket 23,
such slot being of suitable length to permit partial rotation of the collar 22. The lever 9 may be secured against movement through the collar 22 by a set-screw 25, seated in a suitable perforation in the collar 22 and impinging against the lever 9.
26 and 27 are a pair of stops slidably mounted on the lever 9. The stop 26 is positioned between the bracket 3 and the bracket 23, and the stop 27 is positioned on the lever 9 between the bracket 23 and the outer end of the lever. Each stop is provided with a perforated rubber disk on its side adjacent the bracket 23.
The use of our improved device is as fol-.
lows: The casing 3 having been secured to the door-jamb 1 and the slotted bracket 23 having been secured to the door 2, the lever 9 is passed through collar 22 in bracket 23, through head 8, and then secured in adjustment by set-screw 10. Having connected the casing 3 and bracket 23 by adjustment of the lever 9 and it being desired to set the spring to close the door whenever the same is opened, the door is first closed. Then the pawl 9 and dog 21 are set as shown in dotted lines. (See Fig. 6.) The pawl 19 being in engagement with the ratchet-wheel13, the dog 21 is drawn out of engagement therewith, and the lever 18 is thrown forward in the direction of the dotted arrow (see Fig. 6) and the operation repeated until the spring 15 has reached the desired degree of contraction, the dog 21 beingintermittently inserted to prevent expansion of the spring. Upon opening the door the spring 15, which has been partially contracted by this operation, is sufficiently further contracted to, owing to the tendency of the contracted spring to expand, return the door to its closed position upon the same being released.
If it is desired to adjust the spring so that the door will be held open and if closed returned to its open position, the door is first opened. Then the pawl 19 and the dog 21 are set as shown in dotted lines, (see Fig. 6,) and the lever 18 and dog 21 are operated in the same manner as already described, but in the direction of the full-line arrow, which operation causes expansion of the spring 15 to the desired degree. Upon closing the door the spring 15 will be sufficiently further expanded to open the door again when the same is released, owing to the tendency of the spring 15 to contract when the same has been expanded. If pawl 19 and dog 21 are thrown out of engagement with the teeth of the ratchet 13, the spring 15 will then be untensioned, and any movement of the door will revolve the drum 11 and through spring 15 produce a like movementin the ratchet 13, which always revolves with spring 15 unless dogged.
The change of angle between the door 2 and the lever 9 upon being opened or closed is compensated for by the oscillating collar 22 and the slot 2 1 in the bracket 23.
If it is desired to prevent the door closing beyond a certain point in the rotation of the door when the spring 15 is tensioned to close the door, the stop 27 may be adjusted as, for example, shown in dotted lines, Fig. 2. If it is desired to prevent the door opening beyond a certain intermediate point, the stop 26 may be adjusted in like manner. Inasmuch as the lever 9 in opening or closing the door slides through the collar 22, it is evident that the set-screw 25 may be tightened and the door thereby locked against movement.
Our invention is applicable to swinging windows as well as doors, and we do not restrict ourselves to the exact details of structure herein shown and described, as many changes may be made without departing from the spirit of our invention.
