Application August 6, 1943, Serial No. 497,661
1 Claim.
This invention relates to pneumatic riveting guns, and more particularly to the rivet sets thereof.
By way of illustration, it might be stated that frequently the triggers of rivet setting guns are accidentally operated while the gun is being carried from one job to another, with the result that the rivet; sets of the guns are shot from the barrels of the guns, causing damage to valuable property, and frequently injuringfellow workers or persons in range of the projected rivet set.
It is therefore the primary object of the presare so designed that spaces will be provided bedrawing. These spaces, permit the springs to ent invention, to provide means to eliminate the danger caused by the rivet sets being accidentally discharged or projected from their guns in which.
they are mounted. An important object of the invention is to provide means mounted on the rivet sets of pneumatic riveting guns, which will grip the. barrels of the guns to restrict movement of the rivet sets,
beyond a predetermined point.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certainnovel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that' changes may be made in the construction and arrangement of parts Without departing from the invention as claimed.
Referring to the drawing:
Figure 1 is an elevational view partly in section, illustrating a pneumatic rivet setting gun, wherein the rivet set is equipped with a retaining device, constructed in accordance with the invention.
Figure 2 is a sectional View through the barrel of a rivet setting gun, the rivet set being sho in elevation. l t
Figure 3 is a sectionalview taken on line 3-3 ofFig. 1.
Figure t is a sectional view taken on line 4-4 of Fig. 1.
Referring to the drawing in detail, the handle of a rivet setting gun is indicated by the reference character 5, the handle being of the usual and well known construction, and supplied with the usual trigger't by means of which the gun The barrel of the gun is indicated by the reference character 1 and as shown, is provided spirit of the tween the inner edges thereof and the bottoms of the recesses, as clearly shown by Fig. 1 of the press inwardly so that the shoulders 9 may be cleared, should it be desired to remove the rivet set H. l v r Mounted, on the outer end of the rivet set, is a rubber cushioning head M, which is formed with a depression to accommodate the head of the rivet which is being inserted or positioned in anop nins.
From, the foregoing it will be seen that due to the construction shown and described, should the trigger 6 be accidentally operated while the gun is being carried from one job to another, the rivet set ll will be held against outward movement,
beyond a predetermined point, by the contact of the springs ill with the shoulders 9. r
Knobs or finger pieces indicated at I3 are provided on the free ends of 'theisprings, to afford convenience in operating the springs to press them inwardly, when the rivet set is to be released or removed from the gun'barrel.
What is claimed is:
In a rivet setting gun, a gun barrel having internal longitudinal grooves formed at the open end thereof, said grooves presenting shoulders at the outer end of the barrel, a rivet set movable within the end of the gun barrel and havin longitudinal grooves, the latter grooves having inwardly curved portions, spring members se cured within the grooves, thefree ends of the spring members being curved to fit within the curved portions of the grooves of the rivet set, portions of the curved portions of the spring members adapted to contact the shoulders holding the rivet set within the gun barrel, the free ends of the spring members extending beyond the open end of the gun barrel and adapted to be depressed to disengage the shoulders whereby the rivet set may be disconnected from the gun barrel.
