COMBINED DO OR CATCH AND BUFFER.
SPECIFICATION forming part of Letters Patent No. 632,043, dated August 29, 1899.
I Application filed July 11,1898. Serial No. 685,688. (No model.)
To all whom it may concern:
Be it known that I, PERLEY CHANDLER, a citizen of the United States, residing at Barre, Washington county, and State of Vermont, have invented certain new and useful Improvements in a Combined Door Catch and Bufier, of which the following is a specification, accompanied by drawings representing a combined door catch and buffer embodying my invention.
Figurel is a side elevation of my combined door catch and buffer. Fig. 2 is a bottom view of the same. Fig. 3 is a vertical central sectional view showing the door-catch in position to engage the door when it is swung against the buffer. Fig. i is a vertical central sectional view showing the door-catch in position to engage the door with the'buft'er pushed back by the pressure of the door against it. Fig. 5 is a vertical central sectional view showing the buffer in its normal position with the door-catch in position to engage the door. Fig. 6 is a vertical central sectional view showing the door-catch withdrawn into the recess of the buffer with the buffer looked back, holding the door-catch in an inoperative position.
Similar letters and numerals refer to similar parts in the different figures.
The object of my invention is to provide a combined door catch and buffer adapted to receive the impact of the door when it is swung open and alsoto automatically engage the door and hold it open,with means for either permanently latching the door open or hold ing the door-catch in an inoperative position, so that the device can be used simply as a buffer; and it consists in the construction and arrangement of parts, as hereinafter described, and set forth in the annexed claims.
Referring to the drawings, A denotes the buffer, preferably provided with a block of rubber A in its end to receive the contact of the door. The bufier A is mounted upon a spindle A capable of sliding in bearings in a shell or case B, which incloses the door-catchactuating mechanism and is inserted in a mortise formed in the base-board O. The spindle A is pushed outwardly by a spiral B, which normally holds the bufier A a short distance away from the base-board, its
outward movement being limited by a pin 13 striking against a fixed partition 13 in the case B. The buffer A is provided with a recess A on its under side adapted to receive the door-catch D, which is pivoted upon a stud D, held in the case B and having its outer end D rounded and provided with a hook D adapted to engage a staple l, projecting from the side of a door 2.
D is a spring exerting a pressure upon the catch D to throw the hook D out of the recess A and into position to engage the staple 1 on the side of the door.
E denotes a latch pivoted upon a stud E and having its free end adapted tobear against the end D of the catch D and hold it against the tension of the spring D with the hook D of the catch inclosed within the recess A 1E denotes a spring bearing against the latch E, by which it is moved into contact with the end D of the door-catch.
Pivoted to the end of the sliding spindle A is a pawl F, having a projecting pin F and provided with a spring F attached to the pawl and bearing against the side of the sliding spindle A for the purpose of holding the pawl normally in alinement with the sliding spindle A The spindle A is provided with a hole G, (represented by broken lines,) adapted to receive the end of a spindle G, sliding in suitable ways within the case B and provided with a projecting knob G by which the spindle G is pushed into the hole G for the purpose of locking the sliding spindle A and holding it against the tension of the spiral spring B, as hereinafter described.
Attached to the pivoted catch D is a plate H, provided with a notch H, adapted to be engaged by the projecting pin F, carried by the pawl F, and having an inclined or cam surface H to allow the pin F to slide by the end of the plate H into position to engage the notch H.
Assuming the normal position of the operative parts as represented in Fig. 3, the operation of my improved device is as follows: When the door is swung open against the rubber block A in the end of the buffer, the sliding spindle A is pushed into the case B, compressing the spring B and carrying the end of the pawl F against the latch E, which moves it against the tension of the spring E out of engagement with the end D of the pivoted door-catch D and allowing the spring D to rock the door-catch D upon its pivotal stud D and move the hook D out of the recess A and into engagement with the staple 1, which is in position when the door is in contact with the buffer to be engaged by the hook D The position of the operating parts will then be represented in Fig. 4, which shows the pawl F in contact with the latch E, which has been raised out of engagement with the end D of the latch D. When the hook D is moved out of the recess A by the spring D the opposite end D is moved toward the pawl F, carrying the notched edge of the plate I-I into the position shown in Fig. 4 and in front of the pin F. the buffer A from the pressure of the door allows the spiral spring B to move the sliding spindle A outwardly, causing the pin F to slide over the inclined surface H of the plate H and drop into the notch H, as represented in Fig. 5, with the latchE resting upon the end D of the pivoted door-catch D and hook D of the door-catch D in position to engage the staple 1 of the door. When the door is engaged by the hook D as shown in Fig. 2, it is released by pushing it against the buffer A to move the sliding spindle A inwardly, when the engagement of the pin F with the plate H will reverse the motion of the pivoted catchD and carry it into the position shown in Fig.6, allowing the latch E to be carried against the end D of the doorcatch D, thereby releasing the door and locking the door-catch in position with its hook D inclosed in the recess A as represented in Fig. 6.
Removing the pressure of the door from the bufier A allows the spiral spring B to force the buffer outwardly and bring the o erative parts of the mechanism into their normal position, as shown in Fig. 3, when the impact of the door against the buffer-block A will move the latch E and release the doorcatch, as already described.
The action of the sliding spindle A will cause the door-catch D to be alternately moved into the recess A of the buffer and locked therein and moved out of the recess A into position to engage the staple l of the door, so that the pressure of the door against the buffer serves to cause the door to be engaged by the hook D and released therefrom.
By engaging the spindle G with the hole G the sliding spindle A and butter A are locked against longitudinal movement. If the buffer A is locked in position, when the hook D is in the position shown in Fig. 4 the staple 1 will pass over the rounded end D and be engaged by the hook D which must then be released by hand in order to close the door; but if the buffer is locked in position when the hook D is inclosed within the recess A as shown in Fig. 6, then the The release ofdoor-catch is rendered inoperative and the device can be used as a door-buffer alone.
WVhat I claim as my invention, and desire to secure by Letters Patent, is Y 1. In a combination door buffer and catch, the combination of a sliding door-buffer arranged to be moved in one direction by the impact of the door, a spring by which the motion of the buffer is reversed, a pivoted door catch adapted to engage the door, a spring by which said catch is carried into an operative position to engage the door, a latch by which said door-catch is locked in an inoperative position, and operative mechanism by which said latch is released by the movement of said buffer, substantially as described.
2. The combination of a sliding buffer, a pivoted door-catch having a hook at one end arranged to engage the door when in contact with the buffer, a pawl carried by said sliding buffer adapted to engage the opposite end of said door-catch and disengage it from the door, substantially as described.
3. In a combined door-buffer and doorcatch, the combination of a sliding door-buffer, a pivoted door-catch, and intermediate actuating mechanism by which said pivoted door-catch is alternately carried into and out of operative position by each sliding movement of. said buffer, substantially as described.
4. The combination of a sliding buffer, a pivoted pawl carried by said buffer, a pivoted door-catch provided witha notch to be engagedby said pawl, whereby the door-catch is rocked on its pivot, a latch for retaining said door catch, means for releasing said latch, and a spring for reversing the motion of said door-catch, substantially as described.
5. The combination of a sliding bufier arranged to be moved in one direction by the impact of the door, a pivoted door-catch, a spring for moving said door-catch into an operative position to engage the door, means for moving said door-catch into an inoperative position by the sliding movement of the buffer, a latch for retaining said catch in an in-- operative position, means for releasing said latch by the sliding movement of the buffer and means for locking said buffer against a sliding movement, substantially as described.
6. The combination of a sliding buffer, a pivoted door-catch, intermediate connecting mechanism between said sliding buffer and said pivoted catch, whereby said pivoted catch is alternately carried into and out of operative position by each sliding motion of said buffer, and means for locking said buffer against sliding movement and thereby permanently maintaining said catch either in or out of operative position, substantially as described.
7. The combination of a sliding bufier, a
pivoted door-catch adapted to engage the door a. retainingwhen in contact with said buffer,
motion of said buffer is reversed and a door catch arranged to engage the door when in contact with said buffer, said buffer and said door catch being operatively connected whereby the sliding motion of said lender is made to alternately carry said door-catch into and out of operative position, substantia11y as described.
