SUPPORT FOR PNEUMATIC HAMMERS.
Application filed April 20, 1920.
To all whom it may concern:
Be it known that I, NICHOLAS Basso, citizen of the Dominion of Canada, residing at Victoria, in the Province of British Oolumbia, Canada, have invented certain new and useful Improvements in Supports for Pneumatic Hammers, of which the following is a specification.
This invention relates to a mechanical support for a pneumatic air hammer, which is designed to relieve the operator from the fatigue of holding the hammer up to its work.
In the larger size pneumatic hammers the weight of the tool itself is fatiguing to the operator and the reaction of the rapid blows imparted by it impose a severe strain on the muscles and prevent the hammer bein held to its work in a satisfactory manner.
It is to relieve the operator of this fatigue and enable better work to be done that the device, which is the sub ect of this application, has been devised.
In it the hammer is carried in a mechanical support affording ample range of movement in its use, and the tool is held to its work by a spring, leaving the operator free to guide and direct the blows.
The invention is fully described in the following specification, reference being made to the drawings by which it is accompanied, in which:
Figure 1 is a side elevation and part section of the device.
Fig. 2 is a plan of the base.
Fig. 3, an end elevation of the standard and radius arm supporting sleeve.
Fig. 1, a plan of the fork end of the radius rod, and
Fig. 5, an end view of the end bearing of the radius rod to which the spring is connected.
The device comprises a base plate 2 having staggered apertures providing for attachment of it to any convenient support, preferably to the plates being riveted.
In this base 2 a standard 3 is mounted to upwardly project from it. On the upper end of this standard 3 is pivotally mounted on a pin 4 a sleeve 5, in the ends of which nuts 7 are rotatable and are threaded to receive the threaded middle portion of a tubula-r member 6. On each end of the tubular member 6 are ball bearings 8 adapted to receive a radius rod 9 and permit of its endwise and rotational movement therein.
Specification of Letters Patent.
Patented June 14, 1921.
Serial No. 375,308.
On one end of this rod 9 is secured a forked end 10 providing a bearing for a spherical enlargement 11 on the body of the hammer, so that the hammer is afforded freedom of pivotal movement, in the end of the radius rod 9, which rod can be endwise and rotatably moved in its supporting sleeve 6, and the whole may be swiveled on the base plate 2.
On the end bearing 8 of the tubular member 6 which is toward the hammer carrying end of the rod 9 are double lugs 12 between which and similar lugs at the base of the column 3, is connected a strong coiled spring 13. The tension of this spring may obviously be varied by endwise adjustment of the tubular member 6 in the sleeve 5 by means of the nuts 7, to hold the operative end of the hammer tightly against the work to which it is applied. Lugs 14 are provided on each side of the bearing 8, as shown in Fig. 5, by which the weight of the hammer at the end of the radius rod may be sustained when the tool is required to .work horizontally.
In the connection of the sleeve 5 to the standard 3 the jaw portion of the sleeve is of sufficient length to enable the pin 4; to be applied to differently placed holes in the standard, to suit hammers of different lengths.
The base 2 being secured to a position convenient for the work to be done, preferably to the plates being riveted, the operator has a wide range in the use of the support as the rod may be moved freely in and out of the tubular member and various lengths may be provided up to say ten feet, while the swivel connection of the hammer to the end of the rod 9, the free rotation of the rod and the swiveling connection of the standard 3 to the base 2 afford an ample range of varied movement.
The tension of the spring 13 may be adj usted to apply any desired pressure on the rivet, relieving the operator of the heavy muscular effort necessary to withstand the reaction of the hammer blows and leaving him free to direct them where required. Not only does it relieve the operator of the muscular exertion, but it applies the required pressure more steadily and uniformly, and enables a physically light man to do better work than a powerful man can do without it.
The spherical enlargement 11 may be formed as shown in the drawing in the body of the hammer itself, or an existing tool may be secured thereto in any suitable manner.
Havin now particularly described my in vention, I hereby declare that what I "claim as new and desire to be protected in by Letters Patent, is:
1. A holder for pneumatic hammers comprising a sleeve, a tubular member passing through said sleeve and having a threaded portion, nuts on said threaded portion to engage the ends of said sleeve for positioningsaid tubular member, a radius rod endwise adjustable within said tubular member, a standard to which said sleeve is pivotally connected and a spring connecting said standard with said tubular member to hold the operative end of the hammer in contact with the work.
2. A holder for a pneumatic hammer, comprising a radius rod to one end of which is secured an open jaw adapted to engage a spherical enlargement on the body of the pneumatic hammer, a tubular member having a ball bearing at each end in which the radius rod is rotatable and endwise movable, a sleeve in which the tubular member is endwise movable, nuts rotatably mounted in each end of the sleeve threaded to fit a screw thread on the middle portion of the tubular member by which nuts and screw thread and tubular member may be moved endwise in the sleeve and secured in any desired position of adjustment therein, a standard having provision at the upper end for pivotally connecting the sleeve to it a base member having provision by which it may be secured adjacent the work, in which base member the standard is mounted to be susceptible of rotational movement thereon, and a spring between one end of the tubular member and the end of the standard adjacent the base connection to hold the operating end of the hammer on the work to be done.
In testimony whereof I affix my signature.
NICHOLAS BASSO.
