RIVET-CUTTER SAFETY DEVICE.
Specification of Letters Patent.
Patented Oct. 28, 1919.
Application filed March 28, 1919. Serial No. 285,768.
To all whom it may concern:
Be it known that I, Jnssn-E'Asn, a citi zen of-the United States, residing at Silver Grove, in the county of Campbell and State of Kentucky, have invented new and useful Improvements in Rivet-Cutter Safety Devices, of which the following is a spec1fi cation.
This invention relates to improvements in rivet cutting tools and the principal object of the invention'i's to .provide means for holding the severed head of a rivet or the like, and preventing the same from flying about and thus injuring the workmen.
Another object of the invention is to provide means which will catch and hold the head while at the same time permitting the tool to pass by without injuring the holding device.
Still another object of the invention is to so form the device that a portion thereof will act to shield the hand from the bar.
The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims,
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a perspective view of the invention in use;
Fig. 2 is a side View;
Fig. 3 is a longitudinal section;
Fig. 4 is a longitudinal section of a modification;
Fig. 5 is a view of another modification;
Fig. 6 is a view of still another modification,
In removing the rivets and the like from parts containing them,-it is necessary to separate the head from the shank by a cutting tool which is either operated by a pneumatic hammer or by a hand hammer. A great deal of force must be used on the tool to cut through the rivet so that when the head is finally severed the force of the final blow wi l usually throw the head a great distance and with considerable force. When this head strikes a person it is liable to injure him more or less and it is a common occurrence to have workmen blinded by these flying heads.
It is the ob ect of my invention to prevent these heads from flying about and in carr ving out my invention I provide a tubular member 1 which is adapted to be placed over the cutting end of the tool 2. One end of the member is closed as at 3. One side of the member is cutaway as at -iand this cut is extended through the closed end so that this end of the member is of substantially semi-circular form and provides a pocket to receive the cutting end of the tool. T he end 3 thus forms a lip which is directly opposite the cutting edge of the tool when the same is in position for cutting a rivet, as shown in. Fig. 3. It will be seen from this figure that when the head is severed from the shank it will pass upwardly into the pocket formed by the sides and lip and the closed end of the semi-circular member and it will thus be caught and held by said member. It will alsobe seen that as the bevel of the cutting edgeigjstrikcs said lip said member will be forced upwardly so that the tool may pass the same without damaging the end. This bending action of the member is possible as the' member is made of rubber, leather or other flexible material which will give sufiiciently to allow the tool to pass the lip when said lip is engaged by the bevel on the tool.
The upper end of the member is provided with a recess 5 which is formed by cutting away a semi-circular strip from the tubular member so that both the tool and the member may be grasped by the hand. The remaining upper edge 6 will then act as a shield to prevent the bar from striking the 1 hand if the bar should shift laterally.
In the modification shown in Fig. 4, the
member is made of substantially rectangu- I lar form at its upper end to fit the cutting tool 2 which is of substantially square shape in cross section. In other respects the construction of this member 1' is similar to that described, though it is of much shorter length.
In the modification shown in Fig. 5, the tubular member 1 is provided with a cupshape'd head 7. The opening in the side of the member is eliminated in this form as the opening is at the end so that the part 7 entirely surrounds the cutting end of the tool. This form of device is useful in working in cement floors and the like as it retains the material being cut by the 'tool within the enlargement 7 and prevents it from flying about.
In the modification shown in Fig. 6, the
The practical advantages peculiar to my device will be better appreciated when it is stated that the tool 2 is ordinarily actuated by What is commonly known as a pneu matic gun, a device so cumbersome that it ordinarily requires two men for, its proper manipulation, so that it is not feasible to turn the tool about its axis. My device is essentially flexible and may therefore be readily adjusted endwise on the tool and as readily turned about the tool, as when it is desired to discharge a rivet head from the pocket formed at the forward end of the device, as shown in Figs. 1, 2, 3, 4 and 6. Theflexible character of the device also enables the same to frictionally engage the tool and thereby remain of itself in the position in which it is placed relatively to the tool. Thus the device 1. may be shifted back on the tool so as to entirely uncover the tool point and enable the operator to position the tool relatively to a rivet head to be cut, and then the device 1 may be shifted back to the position shown in Fig. 3, so as to preclude flying of the rivet head when the latter is separated from the shank of the rivet.
WVhen the device 1 is shifted back upon the tool in the manner stated, the device will frictionally clasp the tool so that there will be no liability of the device shifting casually on the tool. This is also true when the device is arranged as shown in Fig. 3.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is 1. A sleeve-like device for use on tools for cutting heads from rivets; the said device being formed of flexible material and having the capacityof frictionally engaging I the tool to hold itself against casual movement theieonand also having the capacity of movement endwise of and about the tool and being provided in its forward portion with a head-receiving pocket adapted for use in advance of the cutting end of the tool. which pocket is capable when not in use of being positioned back of the cutting end of the tool.
2. A sleeve-like device of flexible material for use on a tool for cutting heads from rivets; the said device having cl-asping
