ARM-REST FOR PENMANSHIP PUPILS.

Specification of Letters Patent. 7

Patented Feb. 18, 1908.

Application filed July 3. 1905- Serial No. 268278.

T 0 all whom it may concernn Be it known that I, ALBERT ASPER, a citizen of the United States, residing at South Seattle, in the county of King and State of Washington, have invented a new and useful Improvement in Arm-Rests for Penmanship Pupils, of which the following is a specification.

My invention relates to arm rests for use in teaching the forearm movement style of penmanship, and it has for its primary obect to provide an improved arm rest which may be readily attached to the arm and will aid the student in learning to balance the fore-arm upon the lower muscles thereof in a pivotal manner.

With a view to the attainment of these ends and the accomplishment of certain other objects, which Wlll hereinafter appear, the invention consists in the features of novelty which will now be described with reference to the accompanying drawing, and more particularly ointed out in the claims.

In the said drawing, Figure 1 is a perspective view of my improved arm rest, showing v it in position under the arm. Fig. 2 is a lan view thereof. Fig. 3 is a bottom view'. ig. 4 is an end view partially in section on the line 4, 4, Fig. 2. And Fig. 5 is a side view.

1 is a block or ad, which may be comosed of any suitable material, such as rubher, wood, leather, or any other ap ropriate substance, and which is provide curved upper surface 2, complementary in form to the curvature of the under side of the fore-arm, and upon which the muscle of the fore-arm rests, as indicated by the dotted line 3 in Fig. 4. The under side of this block or pad may be of any formation best adapted for wear upon the surface upon which the de vice is to be used, but it is preferably formed with a series of corrugations 4, which prevent the device from slipping about upon the desk or other surface upon which it rests, thereby compelling the student to oscillate the arm solely upon the muscles without moving the muscle at the point of contact between it and the armrest, yet permits the block or pad to be moved transversely of the paper whenever the flexibility of the muscles would not permit the hand to reach further with ease.

In order that the pad may be attached to the sleeve of the user, both sides thereof are provided with pins 5, which pass through with a keepers 6, 7, formed on the edges of the pad,

so as to hold the pins in place and at the same time protect their points. These pins are formed with spring catches 8, so arranged that when the pin is forced home the catch will engage over a beveled shoulder 9 on the keeper 7, and thereby prevent the pin from being accidentally withdrawn, the catch 8, however, being also beveled, so that by applying suflicient force the pin may be readily pulled out when it is desired to detach the device from the sleeve.

The catches 8 are held against rotation, when the pins are forced into place, by shoulders 10, 11, (see Fig. 5) formed above and below the beveled shoulder 9, and between which shoulders 10, 11, the catch 8 engages.

Having thus described my invention, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent, is:

1. As a new and useful article of manufacture, an arm rest for teaching the fore-arm movement style of penmanship, com rising a pad conforming on its upper side to t e contour of the muscle of the arm, in combination with means for attaching the pad to the arm of the user, and means for preventing the movement of the pad by the longitudinal movement of the arm when in use.

2. As a new and useful article of manufacture, an arm rest comprising a pad having a curved upper surface for conforming to the muscle of the arm, in combination with means for attaching the pad to the arm of the user, and means for preventing movement of the pad by the longitudinal movement of the arm when in use.

3. As a new and useful article of manufacture, an arm rest comprising a pad for supporting the arm, and impaling devices at the sides of said pad for attaching the same to A the sleeve of the user, and means for locking said device against movement by the longitudinal movement of the arm.

4. As a new and useful article of manufacture, an arm rest comprising a pad for supporting the arm, provided with keepers at the sides thereof for attaching the pins, in combination with impaling pins passing through said keepers and means on said keepers for preventing rotation of the pins.

5. As a new and useful article of manufacture, an arm rest comprising a pad for supporting the arm, having keepers at the sides thereof, for impaling pins, in combination with impaling pins adapted to be inserted into said keepers, means for holding said impaling pins against accidental withdrawal and means for preventing rotation of the p 6. As a new and useful article of manufacture, an arm rest comprising a pad for supporting the arm and provided with means for preventing movement of the pad by the longitudinal-movement of the arm, said pad having impaling pin keepers at the sides thereof, in combination with impaling pins inserted in said keepers and having spring catches adapted to engage over the edges of said keepers for holding the pins against accidental withdrawal.

7. As a new and useful article of manufacture, an arm rest comprising a pad for supporting the arm, having its lower surface formed with means for preventing the pad from sli ping upon the desk when the arm is moved ongitudinally, and its upper surface adapted to receive and support the fore-arm of the user.

8. As a new and useful article of manufacture, an arm rest for teaching the fore-arm movement style of enmanship, comprising a pad conforming on its upper face to the contour of the muscle of the arm, in combination with means for attaching the pad to the arm of the user, the lower face of the pad being provided with corrugations disposed transversely with relation to the arm.

9. As a new and useful article of manufacture, an arm rest for teaching the forearm movement style of penmanship, comprising a pad conforming on its upper face to the contour of the muscle of the arm, in combination with means for attaching the pad to the arm of the user, the lower face of the pad beingprovided with spaced ribs extending the entire length thereof across the pad and transversely with respect to the arm.

In witness whereof, I have hereunto set my hand this 26th day of June, 1905, in the presence of the subscribing Witnesses.

ALBERT ASPER. Witnesses:

JAY TODD, F. H. TODD.
