Application med August 7, 1911. serial No. 642,852.

To all whom it may concern.'

Be it known that I, ELBRIDGE S. HAINES, of the city of St. John, in the Province of New Brunswick and Dominion of Canada, have invented certain new and useful Im'- provements in Sawing-Machines, of which the following is a full,'clear, and eXact`description. l

This invention relates to improvements in sawing machines, and the object is to provide means for sawing olf the submerged tops of piles or the like.

lThe device consists briefly of a pair of pivoted side members held in parallel relation by links pivoted thereto. A horizontal saw frame is mounted at the lower ends of the side members, means being provided to keep said saw frame always in the same horizontal plane, during the oscillation of the side members. A suitable framework is provided to support the side members, said frame-work being provided with a rack and pinion mechanism for feeding the saw.

n the drawings which illustrate this inkventionz-Figure 1 is a front elevation of the device.` Fig. 2 is a side elevation of the same. Fig. 3` is a perspective view of the lower end ofthe device showing the arrangement of the saw frame. Fig. 4 is a horizontal section on the line 4 4 of Fig. 1. Fig. 5 is a vertical section on the line 5-5 of Fig. 1, showing the resilient mounting of the saw frame.

Referring to the drawings, 6 designates a foundation member of suitable shape such as the angle shown in the drawings. The foundation is slotted or otherwise prepared at 7 to receive a pair of vertical tubes 8, which are connected thereto by brackets 9 having set screws 10 engaging any one of a series of apertures v11, formed at regular intervals in the tubes 8. The lower ends of the tubes 8 are fixed to a small casing 12 which holds the tubes in parallel relation. Passing through each tube and through the casing 12 is a rod 13, pointed at'the lower end 14. These rods are of such length that they may be driven downwardly to engage submerged ground, and thus ancho-r the lower end of the tubes 8,*the upper ends being anchored by fixing the foundation 6 wherever desired. A pair of posts 15 are rigidly attached to the foundation 6, a short distance away from the tubes 8. Pivotally mounted on these posts 15 are a pair of tubular side members 16, built up of sections of pipe 17, connected together by means of Ts 18. The particular sections 1711 which engage the posts 15 are provided with a series of regularly spaced apertures 19, through which the posts pass. The central arms of the Ts 18 are turned rearwardly, d. e., toy face the foundation 6, and to these central arms, linksv 20 are pivotally connected. These links are all of equal length and thereforel hold the side members 16 parallel, but at the same time, allow them to oscillate freely from side to side, as indicated in dotted lines Fig. 1. At the point where the members 16 are pivotally supported on the posts 15, an additional link 21 is provided, having bifurcated ends 22 which embrace the members 16, and are at the same time held in place by the posts 15. A second link 23 similar to the link 21 is provided near the lower extremities of the side members. The bifurcations 24 of this link carry posts 25 which pass through slots 26 in the side members, in order that they may move vertically with respect to the side members. These posts 25 project some distance forwardly of the side members, and carry a saw 27, held in tension between them. A pair of racks 28 are provided,

extending rearwardly at right angles to the links 21 and 23. The lower of these racks is connected to the link 23 in such a manner that the link will slide freely through the .rackin a transverse direction. A vertical shaft 29 journaled to the foundation 6 and to the casing 12 is located midway between the tubes 8. Small pinions 30 are mounted on this shaft in position to engage the racks 28, the lower pinion being located within the casing 12, so as to be protected from floating objects. It will be seen in the drawings that the lower link 23 is in the same horizontal plane with the casing 12, and is permanently maintained in this plane by passing through slots 31, formed in posts 32, projecting forwardly from thek casing 12. A small hand wheel 33 is pyrovided to rotate the rod 29. The lower ends of the members k16 are closed by caps 34, and a short distance above the slots 26, the bore of the members is blocked by a plug 35. The portion of each saw post 25 which passes through the side member is provided with a small block 36, arranged to slide within the member. Helical springs 37 are located within the members 16, be-

tween the block 36, plug 35 and cap 34. Operating ropes or chains 38 may be attached at any suitable point to the members 16. 'Ihe racks 28 are held in engagement with their respective pinions 30, either by means of the slots 39 through which they pass in the casing 12 and foundation 6, or by means of rollers, springs, or other suitable devices not shown.

The operation of the device is quite simple. The foundation 6 is secured to a wharf, interior of a caisson or other desired point. Fine adjustments of height to bring the saw to the proper level are made'by means of the apertures 11 or 19. The rods 13 are then driven downwardly until their points 14 engage the river or sea bed, so as to firmly anchor the bottom of the tubes 8, the top being obviously anchored by the foundation 6. By pulling the ropes 38 alternately, the side members 16 will be oscillated as shown in dotted lines Fig. 1, the links 20 holding said members always parallel. This oscillation naturally causes the reciprocating motion of the saw 27, so that the same will readily cut off the top of a pile or other object against which it is pressed. As the members 16 are pivoted at fixed points, there is bound to be a certain rise and fall of the saw posts 25, carried at their lower ends if these posts were fixed, which would cause the saw to bind, and make the operation extremely difhcult or impossible. This rise and fall is overcome by passing the posts through the slots 26, and connecting them through the medium of 'the link 23. This link reciprocates through the slots 31 of the fixed posts 32, and is thereby maintained in the same horizontal plane, thus holding the posts 25 in this plane so that they move up and down in the slots 26, relatively to the members 16. The saw is fed forward as it cuts by means of the wheel 33, which rotates the pinions 30 and reciprocates the racks 28. These racks being located approximately at the top and bottom of the members 16, keep the same in a substantally vertical position, so that the saw is not inclined by the feeding and is therefore not liable to bind. Since the position of the rack 28 is fixed as regards lateral motion, it is necessary that the link 23 should slide therethrough, as previously stated.

The entire device may be constructed of pipe, pipe fittings, and other standard shapes, so that the cost will be comparatively small. The machine is very compact and may be readily used within caissons or in other cramped quarters. If the sawing to be done is very much below water level, additional sections of pipe may be inserted in the members 16 and 8, the anchors 13 and feeding shaft 29 being correspondingly lengthened. The saw moves always in the same plane and is therefore prevented from binding, so that the device may be very easily operated by the minimum number of workmen. For shipment, the machine may be quickly and readily dismounted and packed in a very small space.

I-Iaving thus described my invention, I de- Clare that what I claim is l.
