UNITED STATES PATENT Orricn.
WILHELM UMLAND, OF NEW YORK, N. .Y., ASSIGNOR TO PETER D. STRAUOH,
' OF SAME PLACE.
DAMPER FOR UPRlGHT PIANOS.
$PECIPICATION forming part of Letters Patent No. 3913. 95, dated October 23, 1888.
Application filed August 13, 1888.
To all whom it may concern.-
Be it known that I, WILHELM UMLAND, of New York city, New York, have invented a new and Improved Damper for Upright Pi- 5 anos, of which the following is a specification.
This invention relates to a damper so constructed that the damper-head may be secured to the damper-block at any desired inclination. Thus the head may be placed in the proper position above the string.
The invention consists in the various features of improvement, more fully pointed out in the claims.
In the accompanying drawings, Figure 1 is a sectional side view of my improved damper. Fig. 2 is a longitudinal central section thereof. Fig. 3 is an end View of the damper-head, and Fig. 4 a top view of the damper.
The letter a represents the damper-1ever,at-
2o tached to hammer-rail by flange b, pivoted at c, the lever carrying the damper-wire (Z, all as usual.
e is the damper-block,which is made of wood and of the form of a disk or drum, having its periphery surrounded by a sheet-metal band, f, to prevent splitting. The block 6 is perforated diametrically-for the admission of the wire d, which is clamped to the damper-block by the screw 9.
h is a pin the shank of which is glued into 1 Serial No. 282,493. (No model.)
a socket of the damper-block. The head h of this pin projects beyond the block and has a rounded or convex face, as shown in Fig. 2.
The damper-head '2', cushioned as usual, is provided with a socket, 2', corresponding in shape to that of head 71 It will be seen that the damper-head may be fitted to the pin at any desired inclination to string A, and that still the contact-surfaces between the damper-head and pin-head will always fit snugly upon one another. The damper-head is secured to the pin-head by glue after the damper-head has been set to the desired angle.
hat I claim is 1. The combination of disk-shaped block 6 with the surrounding metal band f, and with a pin secured to the block 6, and with adaniperhead secured to the pin, substantially asspecified.
2. The combination of a damper-block with a pin, h, having rounded head h, and with the damper-head i, which has a socket, 2', adapted to receive the head h, substantially as specified.
VILHELM UMLAXD.
