OTTO L. HEMIVIING, 0F NEW HAVEN, CONNECTICUT, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE F. B. SI-IUSTER CO., OF NEW HAVEN, CONNECTICUT, A CORPORATION.
RIVETING-IVIACI-IINE.
Specification of Letters Patent.
Patented Feb. 25, 1913.
To all whom t may concern Be it known that I, OTTO L. HEMMING, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Riveting-Machines; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-
Figure 1 a side view with a part of the head broken away, of a riveting machine showing` my improved counterbalance applied thereto. Fig. 2 a sectional view on the line a/-b of Fig. 1. Fig. 3 a broken side view to illustrate the substitution of Springs for the weight.
This invention relates to an improvement in riveting machines, and more especially to riveting machines of the larger type. In the use of these machines the jar or vibra,- tion is so great'that it is usually necessary to set up the machines on a very firm bed, and their use in upper stories of most buildings is dangerous.
The object of this invention is to provide a counterbalance which will overcome vibration; and the invention consists in the construction hereinafter described and particularly recited in the claim.
Secured to the head 2 of a riveting machine of usual construction, I mount a bracket 3 in which is pivoted a lever 4 the forward end of which is connected with the hammer. This is preferably done by coupling the lever to the usual nut 6 which is connected with the slide or cylinder 9 through which the revolving hammer rod 5 extends. At the opposite end of the lever I attach a weight 7 This weight will vary in varying sizes of machines and is of such a weight as to counterbalance the spring chamber and hammer rod and hence prevent the jar or vibration of the machine. It is apparent, and as indicated in Fig. 3, that instead of connecting the weight 7 on the y end of the lever 4, that the end of the lever 4 may be connected with the frame of the machine by springs 8. A counterbalancing lever thus described, not only prevents vibration and enables riveting machines to be used on any floor, but also by preventing vibration enables the machine to be driven at very much higher speed.
I claim In a riveting machine, the combination with the head, the slide and the hammer rod, of a counterbalancing lever pivotally mounted on the head and connected at one end with said slide, and means applied to the other end of said lever for 'counterbalancing the weight of the said slide and 'hammer rod.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
OTTO L. HEMMING.
