SLIDING RIVET-HOLDER.

Application filed September 26, 1918.

cation.

This invention relates to a rivet holder and particularly to a sliding holder which may be supported by and moved along the structure worked upon.

One of the objects of the present invention is to provide a simple, substantial, easily operated rivet holder, which is intended for use in connection with the riveting of the deck plates in steel ships and the like, and particularly to provide a rivet holder which may be supported by and moved along the beams to which the deck plates are riveted, thereby relieving the op erator of the physical exertion of carrying the tool from hole to hole and from supporting or holding the tool while the rivets are being set. Another object of the present invention is to provide means for steering and guiding the rivets while they are being inserted and for forcing the same into position before the riveting hammer is brought into action.

Further objects will hereinafter appear. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is aside elevation of the rlvet holder, showing it in position on a beam while being used.

Fig. 2 is a plan view of the rivet holder.-

Referring to the drawings in detail, A indicates a channel-shaped deck beam and2 the deck plates supported thereby. Adapted to be moved along the lower flange 3 of the deck beam is a bracket or holder generally indicated at B. The lower end of this holder is fork-shaped, as at 1, to straddle the flange 3, while the upper end is provided with two'projecting arms 5, between which is pivotally mounted, on a pin 6, a holding lever 7.

The inner end of the lever 7 is forked, as at 8, and is provided for the purpose of sup porting a rivet set 9. The rivet set is recessed in the upper end, as at 10, for the Specification of Letters Patent.

reception of the head 11 of a rivet 12. The rivet set is secured by means of a set-screw 13 to a pin 1&- which is pivotally mounted in the fork 8, said pin being secured against endwise removal by means of a cotter-pin 15. One end of the pin 14 is projected and turned at right angles, as at 16, to form a lever extension which is provided with a handle or knob 17 This lever will hereinafter be known as the steering lever.

Extending through the lower fork of the holder or bracket B is an adjusting screw 18. This screw is provided for the purpose of adjusting the holder with relation to the flange 3 of the beam, this being necessary as a considerable variation in thickness is often encountered.

When riveting the deck plates 2 to the channel beams A by which they are supported, it is necessary for the operator who sets the rivets to work below deck. The helper working in connection with this man takes a hot rivet from the forge by means of a pair of tongs and places it directly in the rivet set 9 when this assumes the full line position shown in Fig. 1. The rivet setter then grasps the handles 7 and 17, first moving the handle 17 until the rivet 12 alines with the hole 20. He then depresses themain handle 7, thereby forcing the rivet through the hole and into position so that the man who operates the hammer may head the rivet over and drive it into position. The moment a rivet is set it is only necessary for the rivet setter to slide the holder B along the flange 3 of the channel into alinement witha succeeding hole when it is again possible to insert the next rivet.

Many advantages are obtained by the use of a tool such as here shown:

First, it can readily be seen that the rivet setter is relieved of the necessity of supporting the tool when moving it from one hole to another.

Second, it can be seen that comparatively little strength is required to hold the rivet in position while it is being set as he need only apply a slight pressure to the end of the holding lever 7.

Third, the rivet setter working below deck is protected against falling hot scales and sparks as he can at all times stand to one side or at the end of the levers 7 and 17.

Fourth, it is possible for the men to work with greater speed as the amount of physical exertion required is considerably decreased, and it is also possible to obtain better results due to the fact that the rivet is positively held against the lower flange of the channel, due to the pressure exerted by the holding lever 7. The rivets should, therefore, be perfectly set and the most eflicient work possible obtained.

Fifth, the provision of the steering lever 16 which carries the rivet set 9 may be rocked back and forth after a rivet has been placed therein until an absolute alinement is made with the hole 20 Even burnt or slightly large rivets may be easily inserted with the present tool as practically any pressure desired may be ex erted by means of the holding lever 7 to force the rivet into position. The holding lever may also be used as a hammer when forcing a burnt rivet into place by merely lifting the handle up and down as it is being forced into position.

While the tool here shown is particularly adapted for use when working below deck, I wish it understood that it may be used on ships Or buildings or otherwise; and I also wish it understood that the materials and finish of the several parts comprising the tool may be such as the experience and judgment of the manufacturer may dictate.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A rivet holding tool, comprising a holder adapted to be supported by and moved along a beam, a lever pivotally mounted in the holder, a rivet supporting member carried by the lever, and means for steering said member to bring the rivet into alinement with the hole in which it is to be inserted.

2. A rivet holding tool, comprising a holder adapted to straddle a beam and to be slidably supported thereby, a pairof lugs on the holder, a holding lever pivotally' mounted between said lugs, said lever havmg a handle on one end and a forked head on the opposite end, a rivet supporting member pivotally mounted in the forked end of the lever, and a steering lever se cured to the rivet supporting member.

3. A rivet holding tool comprising a bracket having arms adapted to slide upon a beam flange, means for clamping said bracket, a lever fulcrumed to the bracket, a rivet holder pivoted to the inner end of the lever and movable in line with the rivet holes, and an arm connected to the rivet holder and movable to aline the rivet with receiving holes in the beam flange.

"I. A rivet holding tool, comprising a holder adapted to be supported by and moved along a beam, a lever pivotally mounted in the holder, a rivet supporting member carried by the lever, and operating means whereby said member may be tilted forward or backward for alinement of rivet with rivet holes.

5. A rivet holding tool, comprising a holder adapted to be supported by and moved along a beam, a lever pivotally mounted. in the holder, a rivet supporting member carried by the lever, and a steering lever adapted for tilting said member forward or backward for alinement of rivet with rivet holes.

6. A rivet holding tool, comprising a holder adapted to be supported by and moved along a beam, a lever pivotally mounted in the holder, a rivet supporting member carried by the lever, a steering lever attached to said member whereby the member may be tilted forward or 'back ward simultaneously with the raising of the rivet to the hole in which it is to be in serted.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
