To all whom it may concern:

Be it known that we, Riemann C. STEWART and wWALLACE A. STEWART, citizens of the United States, and residing at Covington, Kenton county, State of Kentucky, have invented certain new and useful improvements in Fence-Assembling Apparatus; and we'do declare the following to be a clear, fuil, and exact description of the invention, attention being called to the accompanying two sheets of drawings, with the reference characters marked thereon, whichform also a part of this specification.

T his invention relates to improvements in apparatuses used in the construction of irenfences, of the kind. which consists of upright arts or pickets which are supported and ield in place by longitudinal members or rails. ln the manufacture of such fences the pickets are placed into closely fitting-openings in the rails, the connection being generally completed. by swaginca or calking the met al around the opening where the two fencemembers come together. Apparatus has been provided which serves for the purpose of assembling the fence-elements in proper position and properly spaced and holds them in such position until they are connected to each other, auxiliary means provided for the purpose being used at the time to support them until the swaged joint is formed.

Our invention relates to improvements in the construction of'such apparatuses whereby necessary adjustments for various styles and sizes of fences may be had with great facility and with simpliiied means and whereby the work may be completed without requiring any auxiliary supporting means.

Tn the following specification and particu larly pointed out in the claims at the end thereof, will be found a full description of our invention,` together with its manner of use, parts and construction, which latter is also illustrated in the accompanying two sheets `of drawings, in which:-

Figure 1, is a top-view of the apparatus showing it as it appears when used for the purpose of assembling and spacing the fenceelements. Fig. 2, is a longitudinal section of the apparatus taken on line .22 of Fig. 1. Fig. 3, is a vertical cross-section on line 3 3 of Fig. 1. Fig. 4, is a front-elevation of the apparatus showing it used for supporting the Specication of Letters Patent.

assembled fence-members while they are connected. Fig. 5, is a vertical cross-section on line 5 5 of Fig. 4. Fig. 6, isan enlarged sectional detail view of one of the parts.

The fences in the construction of which this apparatus is used -consist of upright meme bers or pickets A, which are supported by rails B, the former occupying periorations in these latter. They are made up in panels or sections of suitable length, a customary pattern being shown in Fig. 4, the fence occupying however an inverted position at the time, and for obvious reasons it appears larger in proportion to the apparatus than what it is in reality. rllhat is to say the sec tions are longer and contain more pickets. When a fence is to be erected, the required number of such sections as shown in Fig. 4, are joined end-wise, the connection being made at the ends of rails B.

The apparatus consists of a number, two or more, rails or bars which by reason of their function we call spacing bars, three being shown, designated respectively C, D, and E. They are supported on sills F, parallel to each other and form with them a compact frame upon which the work is done. This structure is properly termed an assembling frame. Adjustment is desirable for these bars and we use an arrangement whereby the center bar D, is permanently attached to the sills while the other two are mounted so as to be adjustable to suit different styles and sizes of fences. For such purpose the two outer bars have guides 10, whereby they are slidably mounted on the sills. For their adjustment a number of screws 11, are provided which at their ends are permanently mounted in center bar D, where they are held by collars 12, but remain free for rotation. Theyl pass through threaded openings in the outer bars, these latter being reinforced thereat as shown at 13, so that when these screws are rotated by a suitable removable crank-handle (see dottedl lines in Fig. 1) either or both of the bars may be moved either to or from the center-bar according to rotation. These spacing bars have each a longitudinal groove 14, and are higher on one side of these grooves. A number of spaced notches 15, are arranged in the higher part of these bars and at right angles to the grooves therein and communicate with them.

(See Fig. 6.) These bars are solid iron members preferably made of Wrought-iron rolled to shape. n

For assembling the fenceelements, the described assembling frame is adjusted to occupy a horizontal position as shown in Figs. 1, 2, and 3.. In starting the work, fencerails B, are first placed into grooves 14, and against the higher side thereof, after which the pickets A, are pushed into the perforations previously provided in the fence-rails. Notches 15, aline of course with each other in the three bars'while the preforations in the fence-rails register also with them so that the pickets may be readily passed in. The upright fence-members, properly shaped and cut to right length, are first pushed in from one side of the apparatus, which we call the front-side, note arrows in Fig. 1, no particular regard being had toward alining their ends. Next brackets 16, hingedly attached to front-bar C, are raised up and held so by adjustment of braces 17, which rest against the flangeV of the front-bar. Stop or aliningbars 1S, carried by these brackets, they being preferably of angle-iron, are adjusted thereon in proper position, the arrangement being such that their upright part is on a height with notches 15, and with the ends of the upright fence-members which rest therein. Those latter are now pushed again in opposite direction and against these alining bars, which constitute stops and whereby the ends of the pickets are at once quickly and properly alined, the fence-section appearing then as shown in Fig. 4. W'here the upright fence-members are all alike or of even height one such stop-bar 18, only would be used. l/Vhere two are used, as inthe case iilustrated, the upright part of the inner alining bar must be limited to spaced stops 19, to clear the intermediate pickets which extend beyond and are stopped by the outer bar. The so assembled fence-elements are now secured to the apparatus by suitable lockingmeans, which may be locking-handles 21, pivoted to posts 22, which are attached to the spacingebars. rlhey may thus be swung over the fence-railsB, thereby holding them down in the grooves which they occupy. The pickets are of course held by rails B, and by stop-bars 18.V n Fig. 6, modified locking means are shown, the locking handle 21, instead of swinging over the fence-rails in a horizontal plane, is moved in a vertical lane. It is held in locking position by a atch 23, which is turned up under the end of the same and thereby holds it in lockingengagement. 1n this case the post upon which the locking-handle is pivoted is adjustably attached to the particular spacingbar, so that the latter may be adjusted with reference to the Width of the fence-rail. The assembling frame with the assembled fencesection is now adjusted fromv the horizontal position shown in Figs, 1, 2, and 3, to an upright one as shown in Figs. 4, and 5, this latter position being also such that the underside of fence-rails B, is uppermost. ject of this particular position is to have access to thisk underside by a suitable tool (calkan entirety, it appearing then as shown in e Fig. 4. The frame is now returned te a horizontal position as shown in Figs. 1, 2 and 3, stop-bars 18, are lowered below the assembling plane by dropping brackets 16, which is done by disengaging their braces 17, as shown in Fig. 3, in dotted lines, and another fence-section is assembled for swaging.

If a two-rail fence is to be constructed, no fence-rail B, is placed in the groove of center spacing-bar D. A sufficient number of picket-notches, closely spaced, is provided in these spacing-bars, so as to permit various arrangements and combinations. In all cases they serve for correctly spacing the fence-elements and for their quick assembling and alining, after which they act as anvils While the joints are formed. Such notches, differently spaced might be provided in both sides of the spacing-bars, thus providing for additional fence-patterns. For lower fences, bars C, and E, are moved toward each other. Provision is also made for alining shorter pickets, if such are used in any particular design and for which purpose brackets 16, are also provided on center bar D, to receive additional stop-bars 18, (see Figs. 1, and 2). These brackets may be slipped olf their hinges when not needed, see Figs. 3, 4, and 5.

In large establishments, or where large quantities of fence are made after a fixed pattern and size, these assembling frames may be accordingly arranged as to adjustment, and no eXtra notches, to provide for other patterns, are required in the spacing or anvil bars.

As will be seen no auxiliary means are required when the apparatus is in the swaging position shown in Fig. 5, to support the fence-rails and to act as a support or anvil to be placed under them while the swaging is done from above by means of suitable tools which may be a calking chisel and hammer. This is because the fence-rails are supported practically all around the pickets by the higher side of grooves 14, in bars C, D, and E, and which higher side thus serves as anvilA during the swaging action. The interruption caused by the presence of notches 15 is too limited to interfere in any way with this function.

The assembling frame is supported pivotally to permit its change from the assembling to the calking position and back again, the points oi' support being as near its center as possible. For such purpose we provide trunnion-journals 24, at opposite ends ol center bar D, which are iitted to bearings, in which the frame may turn when adjusted from one position to the other, and as shown in Figs. 3, and 5. It is also desirable to have the apparatus vertically adjustable, particularly when in position as shown in Fig. 5, and to bring the ienceerails to proper height for most convenient application oll the tool while the joints between them and the pickets are formed. For such purpose the apparatus is suspended by a cable 81, and held in any particular vertical position by a counter-weight 29, acting on this cable. This latter engages two pulleys 32, one provided on each ournal and for which they constitute the bearings. One end of the cable is attached at g, then passes around one pulley 32, up over a guidepulley 33, over to two guide-pulleys 34, down to counter-weight 29, back up and over the same to pulleys 34, which have double grooves, down and around the pulley on the other journal and up to the frame where the other end attaches at 7L, (see Fig. 5). As will be observed the cable forms three loops, one on which the counter-weight hangs and one on each side of the apparatus, the latter hanging in these, being supported by pulleys 32, which form the bearings lor the trunnion-journals. By reason of this arrangement movement on any part of the cable affects all loops equally and the frame always moves evenly on both sides up or down. For the purpose of guiding the apparatus during this vertical adjustment, journals g4, are extended beyond pulleys 32, and reach into shoes 26, as shown at 25. The shoes are 'fitted to slide on vertical guides 27, provided on frame-*standards 28. The guide-pulleys may be attached to a ceiling or to a crossebeam which connects the lramestandards. There is also a lock to hold the apparatus against swinging on its pivots. It consists substantially of a locking-bar 30, mounted with a sliding adjustment on the rear-bar ll, and is provided with a notch in its end adapted lto engage one oi guides 27, when the apparatus is in the upright position shown in Figs. 4, and 5. A handle 35 is provided for its manipulation.

To hold the apparatus steady when used in the horizontal position for assembling, there are two stops 35, adjustably supported on brackets 37, which are adapted to be swung 'under the outside bars C, and E, when standards.

41, are knobs attached to the. cable to manipulate the same for adjusting the height ol the apparatus, hanging in the loops oi' it.
