(01. 116-1167) '7 ‘ " 1 This invention appertains to door knockers and more particularly to door knockers of the mechanical type for producing a series of rapid from a solid block of material such as wood, but obviously the same can be formed from cast metal or pressed from sheet metal. The inner blows or knocks on a door. face of the body 5 has formed therein ‘anin wardly extending cavity 6 in which is mounted the operating mechanism for oscillating the head 1 of the knocker. Communicating with the cav ity 6 through the upper end of the body is a One of the primary objects of my invention is to provide a door knocker having a novel and attractive form shaped to simulate the appear ance of a Woodpecker With means for rocking the head of the Woodpecker against the door for pro passageway 8. The head ‘I carries a forwardly ducing the desired sound to attract the house 10 extending broad bill 9 which normally projects holder to the door. beyond the inner face of the body for engaging Another salient object of my invention is to the door D as will be later set forth. The bill 9 provide a door knocker in the form of a wood pecker having a pivotly mounted head with a is preferably tapered toward its forward end, but wheel or ratchet for oscillating the head. A further and more speci?c object'of my in through the passageway 8. The neck terminates the same terminates in a broad tapping face I0. forwardly extending bill for rapping on the door 15 Formed on or secured to the head 1 is a depend with means including a hand crank and a star ing neck II which extends into the cavity 6 in a pointed end I 2 for a purpose which will also vention is to provide a novel means for mounting be later described. A pivot pin l3 connects the the head on the body of the knocker and for 20 neck with the body 5 whereby the head is free normally urging the head and bill into engage to rock back and forth to permit the engagement ment with the door. 5 of the bill with the door. A still further important object of my invention Particular attention is invited to the leaf is to provide a door knocker of the above char springs M as the same form an important fea acter which will be durable and e?icient in use, 25 ture of my invention. "The front ends of the one that will be simple and. easy to manufacture springs I4 are secured as at l5 to the upper and one which can be placed upon the market at end of the body on each side of the neck H and a reasonable cost. the rear ends of the spring curve upwardly, as With these and other objects in view, the in- I at It into engagement with the lower face of . vention consists in the novel construction, ar 30 the head ‘I in rear of the pivot 13 and normally rangement and formation of parts, as will be urge the head forwardly and the bill into engage hereinafter more speci?cally described, claimed and illustrated in the accompanying drawing, in ment with the door. ‘ Rotatably mounted in the body 5 below the neck II is a transversely extending shaft l‘l. which drawing: Figure 1 is a longitudinal sectional view 35 Mounted upon the shaft for rotation therewith through my door knocker taken substantially on is a star or ratchet wheel [8 and this ratchet the line I—I of Figure 2 looking in the direction Wheel is deposited within the cavity 6.

One end of the shaft protrudes be gles to Figure 1 and substantially on the line 2-2 yond the body 5 and has connected therewith a of Figure 1 looking in the direction of the arrows. handle or crank 20 to permit the rotation of the Figure 3 is a horizontal sectional view taken shaft by a person. In order to permit the easy on the line 3-3 of Figure 1 looking in the direc fastening of the knocker to a door D, the inner tion of the arrows. 45 face of the body has secured thereto transversely Referring to the drawing in detail wherein extending straps or brackets 21 which protrude similar reference characters designate corre beyond the side face of the body. Screws 22 can sponding parts throughout the several views, the extend through the straps and into the door for letter K generally indicates my door knocker and securing the knocker ?rmly to the door.

As illustrated, the same in‘ wardly away from the door against the tension cludes an elongated body 5, preferably formed 55 of the leaf springs l4.

By turning the crank rapidly a series of quick raps means for rotating the shaft, a wheel having radially extending points secured to the shaft for can be produced which will formulate the noise made by a Woodpecker. From the foregoing de the body having a depending neck extending into scription, it can be seen that I have provided a 'door knooker of an exceptionally simple form which can readily take the form of a wood rotation therewith, a head on the upper end of the cavity and having its lower end arranged in the path of the wheel points, a pivot pin rock ably mounting the neck intermediate its ends on pecker =andswhich ‘will formulate the?noise made 10 ‘itheirbody,‘*leaf‘springs ‘disposed on opposite sides by a woddpecken?whenathe knocker’is operating.’ ‘of‘the-neck' having their forwardv endssecured to the upper end of the body and their rear ends Changes in details may be made without de parting from the spirit or the scope of my inven-‘ ' .:.curved upwardly and rearwardly into engage » mentrwith the head in rear of the pivot for nor tion, but what I claim as new is: i H H ._ A door knocker shaped to simulate a wood mally urging the headvforwardly, and a striking pecker comprising a body having :an grinterior ' V -;bill:carried:by said head and projecting forwardly cavity, means carried by the?forward iace of the body for connecting the same" to a support, said cavity opening out through the upper endilofathe 7 I ‘therefrom.
