INVENTUR BENJAMIN QHANLY, or OAKLAND, CALIFORNIA.

' Application filed May 19,

To all whom it may concern V Be it known that I, BENJAMIN M. HA LY, a citizen of the United States, residing at Oakland, in the conntybt Alameda and State of'California, have invented new and useful Improvements in Hot-Rivet Passer-s, of which thefollo'wing'is a specification.

The present invention relates to apparatus for delivering hot rivets fromv a rivet forge or furnace to variouspoints of a ship, build ing or other construction j oh. I

The primary object of the invention is to provide comparatively inexpensive and simply constructed and operated apparatus of the character described which will deliver point or points and to ordinarily inaccessible places, in a more expeditious, reliable and convenient manner and Without danger of injury to workmen or requiringthe employment of as many workmen or rivet forgers and other equipment as are necessary under thepresent hand passing system, wherebya saving in labor, time and expense isprovided. Anotherobject of the invention is to pro vide apparatus of the character described which will entirely eliminate the necessity ofpassing hot rivets by hand and insure the delivery of each rivetto the predetermined or designated point whereby dropping, cooling otf and loss of rivets are prevented.

The invention possesses other advantages and features some of which, with the toregoing willjbe set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawingsac companying and forming apart of the present specification. In said drawings I have shown one formof the construction of my 1nvention,-but 1t lsto beunderstood' that I do not limit myselt to such jformslngce the invention as expressed in theclaims'may be embodied in a plurality of 'forms. Referringtothedrawings:

in the operation of the. apparatus, 'a hot' rivet is "taken fro r'nthe for'ge and placed into the intake of the pi'ping. The operator then opens the zv'alve and compressed"'a iris charged into the piping and rapidly 'impels the hot rivet to the take-off pipe." When: the

The workmen may shiftthe-bucket to any one of the take-oil openings in the take-oft pipe which pipe may be from 15 to feet or longer, with as many take-off openings as desired. In this way the'delivering of hot rivets to any part of the hull or building may be provided for in a reliable, cheap and time savingmannerr One practical embodiment of the invention is illustrated, in the accompanying drawings, in connection with a ship hull, and comprises a system of pipingl made up of pipe sections having adiameter sufficient to permit rivets to be rapidly impelled there through. These sections extend vertically as -at Qthen horizontally asat 8 and then vertically as at 41, which section 4 is the take-oft pipe. Said section may be otherwise arranged as desired Theupper end of the section 2 isarranged adjacent to a rivet forge or furnace '5 which, as shown, is installed upon the deck 6 of a ship hull. An inclined intake pipe? is disposed adjacent the forgeand is branched out" from one side of thepipe section 2, said intake having an enlarged mouth 8. A compressedair supply pipe 9 is connected with the upper end of the section 2 above the rivet intake pipe and has a suitable valve .10 thereon. This air pipe is connected with a suitable source o-tcompressed air not shown, and has a nozzle 11 extending into the pipe section 2, to a point substantially opposite the lower end of the intake pipe, so as to create a suction in the intake Jpipe. when the compressed air is directed downward into said section 2.

I [The vertical take-off section or pipe 4 is disposed at the point where riveting of the plates 12 is required and this point may be forward. attor amidshi s the other i e 1 P a P P sections being suitably laid to make proper connection with the pipe 1. Takeofl pipe is provided on-one side with a plurality of spaced hot rivet take-off or discharge openings 18, which may be three or more feet apart as desired. Each of the openings is controlled by independent means for open form.

ing and closing the same, which means is preferably the form of a sleeve 14 rotatable upon the pipe and held against sliding thereon by, stopmeans 15,0f any suitable an opening as at 16 which is adaptedto register -W1tl1 an opening 13 when the sleeve is turned' or rotated onthe pipe 1. When otherwise turned these sleeves will close the take-oft or discharge openings. 1

3 To provide forjcatching, the rivets delivered through. the openings 13, I employ a suitable bucket 17 having one side cut away. as at 18, so as to register with the openings 13 and 16. This bucket is supported upon the pipe opposite the opening Each sleeve is slotted or formed with the bucket I employ a deflecting member in the form of a tongue or strip 20 carried by the bucket and arranged to extend through the openings 13 and 16 into the pipe. 4 so as to lie in the path of the rivets. This member or tongue is inclined or shaped so that when the rivets come into contact therewith they will be deflected sideways out through the openings 13 and 16 in a clownward as well as outward direction and into the bucket. The bucket is cut away on its outer sideas at 21, so. as to permit the operator to readily insert tongs, notshown, to remove the rivets. Any suitable means may be usedfor temporarily holding the piping in place and it is not thought necessary to describe this obvious expedient.

O perat'ion.

A hot rivet is placed in the intakepipe 1 and the valve 10 is immediately opened. A, charge of compressed air will be directed through the nozzle 11 into the piping 1 and willrapidly impel. the rivet through the piping. With the bucket set, as shown in Figs. 1 and 2, when the rivet encounters the deflecting member 20, the rivet will be thrown or discharged into the bucket from which it may be readily removed. The valve. need be kept open but a moment in order to cause the rivet to be forciblyand swiftly impelled and the rivet in thus being quickly delivered in a metal pipe will not cool off and will be hot when delivered tothe point of its use. Thus, each rivet requires but a small an'iount of air to; cause its delivery through the piping. I v. 1

its the work advances the bucket is advanced along the pipe 4. If the pipe is 30 feet long, for example, and has from five to eight takeoff openings, the bucket may be placedat any of these openings to receive the rivets. this apparatus the rivets may be delivered Thus itwill be seen that with 7 hot at various pointsthroughout a height 24- with the take-ofi' pipe 25 extending horizontally close to the bottom 26, of the ship. This take-off pipe is connected with a system or line of piping 27 which latter corresponds to the piping 1 of the form of invention heretofore described, and said piping is connected with the air line and associated with the forge, (both not shown) as in said piping 1. The under side of the take-off pipe 25 is providedwith a plurality of spaced discharge or take-off openings 28 controlled by sleeves 29, rotatable on the pipe and having openings 30 therein, adapted to register with the openings 28. These sleeves are similar to the sleeves 14, being independently operable to open and close the openings 30.

A bucket 31 is movable along the pipes 25 so as to be disposed opposite any of the openings 28 and has hooks 32 adapted to engage over and upon said pipe, whereby the bucket will hang under the said openings. The operator may slide the bucket from one opening 28 to another along the pipe, dependent on the point of work. To deflect the rivets a deflecting member 33 is inserted into the pipe through the openings in the pipe and sleeves at the desired point along the pipe. This member is similar to the one 19 and is carried on a curved jaw 34 of a two jaw clamp, the'other jaw 35 of which, being adjustably connected by means of bolts 36 and nuts 37 The jaw 34 is curved to conform to and embrace the pipe, having lateral flanges 38 on its free ends. The jaw 35 engages upon the upper side of the pipe and the bolts 36 extend therethrough and through the flanges 38, with the nuts 39 on the upper ends thereof, whereby a quick clamping and unclamping may be effected. The operation of this form of the invention is carried out in the same way as in the form hereinbefore described, the deflecting member and bucket being moved to the desired point or advanced with the advancing of the riveting operation.

lVhile I have shown and described the invention in connection with'ship building work, it is obvious it maybe equally well.
