T0 all whom t may concern.'
Be it known that I, ANTON GJELSTAD, a subject of the King of Norway, residing at Sandefjord, in the Kingdom of Norway, have invented certain new and useful Improvements in Frames for Riveting-Tools;
and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and Y use the same, reference being had to the aci companying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
The present invention relates to a support for pneumatical riveting hammers-and particularly for hammers for working from below for instance at the bottom of a ship.
The object of the invention is to provide aV support of this kind which is able to keep v the hammer in position and at the same time guide it in such a manner that it moves on a conical surface therebyv hammeringthe rivet from varying angles in succession.
On the drawings:
Figure 1 is a vertical section andFig. 2 is a plan of the apparatus with'the top removed. v
`The support comprises a tripod having adjustable llegs 1 Von which is mounted a base plate 2 carrying a guiderame consisting of a plurality of upwardly inclined converging bars 3 connected at their upper ends by a bearing ring 3. l
The riveting hammer (not shown) is preferably of the pneumatic type of any suitable well-known construction, and is supported in an upright position within the guide frame, the upper portion of the hammer casing projecting loosely through the ring so that the longitudinal axis of sald casing is free to describe a cone, or is readily shifted from a vertical to an inclined plane, as hereinafter described.
A` disk 6 is concentrically j ournaled in the base plate 2 and is rotated thereon by a crank 6 through the medium of a bevel gearing 62. Pivotally mounted on the rotatable disk, near the periphery thereof, is
Specification of Letters Patent. Patented Fel). 25, 1919. Application led October 12, 1917. Serial No. 197,022. i
a guide piece 5, and inthe top face of the latter at a point capable of intersecting the axis of the disk 6 is a recess t, forming a seat for the base of the casing of the riveting hammer.
I For the purpose of shifting the seat 4 eccentrically to the axis of the disk Y6 and thereby inclining the casing of the riveting hammer, the guide piece 5 is conveniently provided with an extension or handler?, and, in order that the guide piece may be locked with the seat in the desired position, a locking screw 8, carried by the extension, is'
adapted to take into any' one of a series oi`V holes formed in the disk 6 concentric to the plvot of the guide ypiece 5.
By adjusting theguide piece 5 by means of handle 'Z and screw 8 the recess 4: will be placed 1n a more or less eccentric position ywith regard to disk6, and will whenthe disk 6vr is rotated, consequently move the lowest part of the hammer in l. frame for theA hammer, a rotatable disk, a support for the hammer carried by the disk, and means to adjust the support relatively to the axis of the disk and thereby change the inclination of the longitudinal axis of the hammer.. j
3. In a frame vfor pneumatic riveting hammers, a guide frame for the hammer, a rotating disk and an eccentrically adjustable vguide piece having a seat for the hammer arranged to intersect the axis of the disk.
n 4. In a frame for pneumatic riveting hammers, a frame forsupportingthe upper portion of a hammer casing, a rotating disk, a guide piece pivoted on the latter near a circle of Ya l yof the disk t0 receive the loweil end of the periphery thereof and hnx'ng a recess therein normally located in the axis presence of two Subscribing Witnesses.
