SPECIFICATION forming part of Letters Patent No. 784,390, dated March 7, 1905.
Application filed May 24, 1904. SerialNo. 209,559.
To 1/, 7072/0177, it may concern.-
Be it known that I, VVILLIAM Soor'r DUN- RAM, a citizen of the United States, and a resident of Sharpsville, in the county of Mercer and State of Pennsylvania, have invented a new and Improved Arm-Rest, of which the following is a full, clear, and exact description.
The invention relates to arm rests or supports for the use of riflemen and other persons requiring a steady arm in the exercise of their vocations.
The object of the invention is to provide a new and improved arm rest or support arranged for convenient attachment to the users body and capable of allowing free movement of the users arm and at the same time giving the desired support to the arm.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. I
Figure 1 is a perspective view of the improvement as applied, part of the users dress being shown broken out. Fig. 2 is an enlarged side elevation of the improvement, parts being in section. Fig. 3 is an enlarged sectional side elevation of the improvement, showing the supporting-arm locked in an extended position. Fig. 4 is a like view of the same, showing the parts in adifl'erent position;
and Fig. 5 is a cross-section of the same on the line 5 5 of Fig. 1.
On asuitably-constructed beltA is secured a metal plate B, having bearings C for the lower end I) of a post I) to turn in, the said belt being adjustable on the users body to bring the post in vertical alinement with the armpit of one of the arms, as plainly indicated in Fig. 1. The postl) preferablyterminates at its upper end in a fork D provided with a pivot-pin E, on which is mounted to swing the heel F of a bar or arm F, carrying at or near its free end a curved plate F forming a rest for the forward end of the users arm, to which the plate is strapped by a strap-and-buckle device (Jr, as shown in Fig. 1.
In order to lock the bar F in an extended position thatis, at an angle to the post D te form a rest for the users arm, the following-device is provided: Between the members of the fork D is pivoted a pawl H, pressed on by a spring H and adapted to engage with its free end anotch F formed in the peripheral face of the heel F to support the bar F in an extended position, as plainly shown in Figs. 1, 2, and 3. In one face of the heel F is formed a recess F", in which extends a fly I, pivoted at I on the said heel F, the fly being adapted to swing with its free end past one end of the notch F, the said recess F being shaped to extend beyond both sides of the notch, as will be readily understood by reference to Figs. 3 and 4. The outer edge of the fly I is tapering and extends slightly at its forward portion beyond the peripheral face of the heel F (see Figs. 3 and L) and the free end of the pawl H is made sufficiently wide to extend across the notch and the fly. See Fig. WVhen the bar or arm F is in a lowered or folded posi tion (see dotted lines, Fig. 3) and the said bar F is swung upward by the user raising his arm, then the free end of the pawl H glides over the peripheral face of the heel F to finally drop into the notch F and thereby support the bar F in an extended position for the arm of the user to firmly rest on the said bar and steady the arm while shooting or aiming. Then it is desired to swing the bar Fback to a folded position, it is only necessary for the user to first swing his arm a short distance upward for the free end of the pawl H to pass out of the notch F to glide over the outer edge of the fly I a distance to the rear thereof, and then the operator swings his arm, and with it the bar F, all the way downward, so that thepawl H engages the fly and swings the same upward for the fly to carry the free end of the pawl across and beyond the notch for the free end of the pawl now to travel again on the peripheral surface of the heel F above the notch.
As the post D is mounted to turn in the bearing C, it is evident that the user can readily swing his arm freely around, to bring the arm in the desired position for supporting the rifle or other device to be supported at the time the users arm is firmly and steadily seated on the bar F. It is understood that the user has free lateral movement of the arm no matter whether the device is extended for supporting purposes or folded up.
Hay ing thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. An arm-rest comprising means for attachment to the body of the user, a vertical member supported thereon, and provided with a fork at its upper end, an arm-supporting member, mounted to swing with reference to the vertical member, and having a circular heel working in said fork, said heel being formed with a notch in its periphery, and having a recess in one of its faces, the sides of which extend to either side of said notch, a fly pivoted to swing in said recess, and a spring-actuated pawl cooperating with the fly, the free end of which is received by the notch to hold -said arm-supporting member in the desired position.
2. An arm-rest comprising means for attaehment to the body of the user, a post rotatably supported thereon and provided with a fork at its upper end, an arn'l-supporting member mounted to swing with reference to the post, and having a circular heel working in said fork, said heel being formed with a notch 'l.
