BOILER-SEAM PROTECTOR.

Application filed. May 25, 1916.

To all whom it may concern:

Be it known that I, JOSEPH J. GAGE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Boiler-Seam Protectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in means for protecting the seams of boilers against the excessive heat within the firebox.

The main object of the invention is to provide simple yet eflicient means whereby the protecting covering may be secured in place without forming screw or bolt holes through the boiler.

A further object is 'to improve generally upon the construction of protectors of the class described to such an extent as to render them simple and inexpensive, yet highly efficient and durable.

With the foregoing general objects in view, the invention resides in certain novel features of construction hereinafter fully described and claimed the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a vertical section through a boiler showing the application of the improved protector to the outer surface thereof;

Fig. 2 is an enlarged sectional view through the seam and protector shown in Fig. l;

Fig. 3 is a vertical transverse section on the plane of the line 33 of Fig. 2;

Fig. 4 is a sectional view similar to Fig. 2 but showing the application of the pro- 'tector to the inner surface of a boiler;

Fig. 5 is a perspective view of one of the anchoring members; and

Fig. 6 is a similar view of one of the supporting members.

In specifically describing the construction shown in the drawings above briefly described, similar characters will be employed to designate corresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective indices. To this Specification of Letters Patent.

end the numerals 1 designate the overlapping ends of two sections of a boiler, such ends being secured together by the usual rivets 2 whose heads 3 project beyond the inner and outer surfaces of the boiler. If the inner heads of the rivets are subjected to intense heat and thus prone to be injured, the improved seam protecting means to be described will be applied over said heads, but if the outer heads of the rivets are so disposed as to be subjected to injury from the heat, said means will be applied on the exterior of the seam. In either case the heads of the rivets at suitable intervals will be provided with grooves 4 to receive therein projecting ribs 5 on the opposed sides of anchoring members 6 which are shown in the present embodiment of the invention as being in the form of nuts, said nuts being forced or wedged between certain of the rivet heads as shown clearly in Figs. 2 and 4t.

Attaching members 7 in the form of semicylindrical blocks of any preferred material are disposed beneath the grooved rivet heads and are formed with longitudinal channels 8 receiving said heads as well as the aforesaid nuts 6, bolts 9 being passed through the member 7 and threaded into the aforesaid nuts. As shown clearly in Figs. 2, 8 and a, the heads of the bolts 9 are countersunk in sockets 10, this construction being preferable in most forms of the invention although in some types thereof the bolt heads might be permitted to protrude.

A protecting covering of refractory material is secured in place by the members 7, said covering consisting of a plurality of channel-shaped sections 11 disposed end to end and having a detachable interlocking engagement with the aforesaid members. In the present form of the invention the interlocking means is shown in the form of internal ribs 12 on the sections 11 and external grooves 13 formed in opposed sides of the members 7. It is to be understood, however, that any suitable connecting means might well be employed for securing the covering to the last named members, and in fact, within the scope of the invention, said covering might well be secured directly to the anchor members 6.

From the foregoing it will be obvious that I have provided extremely simple means of securing a protecting covering to the exposed seams of boilers and that the. improved arrangement will be highly efficient and durable regardless of its simplicity. Particular emphasis is laid upon the fact that it is unnecessary to puncture the boiler to permit application of the improved features of construction thereto, this being a salient feature of the invention since it permits the covering to be secured in place much more easily than is possible when bolt or screw holes must be drilled or punched through the boiler.

The invention is adapted primarily for use upon the girth seams of boilers, which seams are exposed to the intense heat from the fire-box but it is to be understood that if found desirable it may be employed on any other style of seam. Furthermore, although a number of specific details of construction have been shown and described for illustrative purposes, numerous changes may be made within the scope of the invention as claimed without sacrificing the main advantages thereof.

I claim 1. A boiler seam protector comprising a plurality of anchor members adapted to be supported by the projecting rivet heads at the seam or seams of the boiler, a refractory seam covering, and means for securing said cov-.

ering to said anchor members.

2. A boiler seam protector comprising a plurality of anchor members adapted to be supported by the projecting rivet heads at the seam or seams of a boiler, said members having ribs for interlocking engagement with grooves formed in said heads, a refractory seam covering, and means for securing said covering to said anchor members.

3. A boiler seam protector comprising a plurality of anchor members adapted to be forced between the projecting rivet heads at the seam or seams of a boiler, said members having outstanding ribs on opposed sides for reception in grooves. formed in said heads, a refractory seam covering, and means for securing said covering to said anchor members.

4. A boiler seam protector comprising a plurality of anchor members adapted to be supported at intervals by the projecting rivet heads at the seam or seams of the boiler, supporting members adapted to be secured to said anchor members and provided with anchoring means, and a refractory seam covering consisting of a number of sections disposed end to end and having anchoring means for interlocking detachable engagement with said anchoring means on said supporting members.

5. The combination with the projecting rivet heads at the seam of a boiler, of a plurality of anchor members supported by said heads, and a refractory seam covering supported by said anchor members.

6. The combination with the projecting rivet heads at the seam of a boiler, said heads having grooves formed in their sides, of a plurality of anchor members having ribs received in said grooves, and a refractory seam covering, supported by said anchor members.

7. The combination with the projecting rivet heads at the seam of a boiler, said heads having grooves formed in adjacent faces, of a plurality of anchor members interposed between said heads and having outstanding ribs received in the aforesaid grooves, and a refractory seam covering, supported by said anchor members.

8. The combination with the outstanding rivet heads at the seam of a boiler, said heads having grooves in'adjacent faces, of a plurality of anchor members interposed between said heads and having outstanding ribs received in said grooves, supporting members having grooves receiving said heads and anchor members, means for securing said supporting members to said anchor members, and a channel-shaped refractory protector covering said supporting members and formed of a number of sections disposed end to end, said sections having interlocking detachable connections with the supporting members.

9. A protector for riveted boiler seams comprising a refractory covering for the seam, and means for supporting said covering from the rivet heads of said seam.

10. The combination with a riveted boiler seam, of a refractory covering for said seam supported by the rivet heads thereof.

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

JOSEPH J. GAGE.
