` ENGINE STAND.

Application led October 29, 1921. Serial No. 511,349.

This invention relates to engine .stands for supporting motors so that the same may away from the arms of the stand, as welll as being capable of being positioned at any angle thereto within the usual limits required.

Further objects of the invention will be apparent from the following description and include the s everal improvements illustrated and described and covered by the claims.'

There are a number of engine stands on the market today, some of them being quite satisfactory with certain types of engines, but which are not adaptable for use with other types. With the present stand any motor of any type from a light two-cylinder buckboard motor to the very heavy automobile truck motors may be accommodated. lThis great range of service is possible due to the various adjustable Jfeatures of the present stand, for example, the standards are movable with relation'to each other; the heads are adjustable vertically; the arms are pivoted so as to swing through the entire 360; the carriers are slidable throughout the length of the .ways or arms; the distance pieces are secured to the carriers and to the cross-piece by pivotal means so as to be secured at any desired angle; and the supporting or spacer members are movable freely in the longitudinal slot of the crosspiece and are adjustable at any distance therefrom.

As shown in the perspective view, the motor is secured to two of the carriers in the same manner as it is secured to the chassis frame, while .at the other end the supporting members and the cross-piece hold the front end of the motor in a position of convenient accessibility, the supporting members attaching directly to the inner face of the gear housing, the panel for which is removed before the motor is attached to the frame. l

Fig.'r 1 is a perspective view of my device 1n lts preferred form, and

Fig. 2 is a central vertical section through the cone clamp and head of the standard.

Fig. 3 is a perspective of the device shown with a different motor and with the pivoted arms turned thru approximately 180.

My device consists of three main parts, namely, the frame A, the standards B, and

the truck C. The frame is pivoted to the standards and the latter are mounted in pedestals 10 and 11, respectively, one of which may be permanentlysecured to the truck, while the other is adjustable thereon 4to correspond to the diierent widths ofchassis in common use. The truck is preferably fu'rnished with casters or wheels so as to be conveniently moved from place to place.

The truck consists of a pair of wheeled bases 12 and 13 which may be of different lengths as shown, each consisting of a pair of angle irons secured together at either end 'by their fasteningl to the caster support 15 and intermediately by the angle clips 16 t0 which are secured the parallel beam's 17 forming the longitudinal members of the truck.

Each of the pedestals consists of a single casting providing a vwide base 19 grooved to tit the corners of the bars 17 and recessed-to form four legs to reduce the friction of the pedestal against the bars whenl the former is moved. From the base 19 rises a socket 2O centrally strengthened on either side by a triangular stiti'ening member 21, the socket being split on either side and in proximity to the stitiening member 21 so that one slot will be to the right of one of these stiening members, while the other will be to the lett ot the opposite member, in order that each split portion shall consist of a semicylinder and an integral stiifening web.

The standard B consists of two telescoping portions 22 and 23, the former being secured in the socket of the pedestal by a bolt 24, which not only binds the member 22 to the pedestal, but also draws together the two split portions of the socket.v The inner and smaller member 23 of the standard receives at its upper end the' head 25 which may b'e secured to it in any, desired manner and at its lower portion is perforated with a number of holes 26 adapted to engage with a pin 27 passing through the upper endK of the member 22 so as to hold the head of the telescoped standard at the desired adJusted height. x c

The head 25 is provided at one side with a cup member 29 into which is fitted the cone clamp 30 which is provided in its outer flat face with a grooved recess 3l to receive the arms 32 forming the longitudinal members of the frame A.- A bolt 33 having a reduced end 34 is mounted centrally of the head and cup member and passes through the cone clamp 30 as well, the shoulder between the larger portion of the bolt and the reduced portion 34 abutting against the` outer face of the angle iron arm 32 which is secured against such shoulder by means of the nuts 35 so that the bolt, clamp and angle iron arm' move as a unit, and may for all purposes be considered as integral.y The end ofthe bolt 33 that passes through the head is threaded to receivea nut 37 which is loosened byV means of a socket wrench, such as 38 to permit the turning of the frame on its pivots and when this nut 37 is tightened, the frame is locked in position by means of the frictional engagement between the cone clamp 30 and the correspondingly shaped recess in lthe cup 29.

The supporting arms 32 plvoted as )ust described are capable of swinging throughout the entire 360o of a circle so that when a motor is mounted upon these arms in the way illustrated, the motor can be swung into any desired position and the frame may be locked to maintain it at the chosen angle by merely tightening the nuts 37. A pair of carriers 40 are slotted to slide upon the arms 32 and may be secured at any distance from the pivot by tightening the set screw 41. These carriers each has an inwardly extending projection 42 serving as a bracket to support the rear end of the motor and for this purpose the bracket is slotted to receive the standard bolt which secures the usual integral ear of the fly wheel casing to the chassis frame. In some motors the rear end is not supplied with ears loverlapping the chassis bars', but is secured to them by means of special fittings'. In such cases as' this an angle clip is mounted upon the bracket end of the carrier and the rear end of the motor frame is secured to this an le .clip in well known manner.

The ront end of the motor is secured to the frame A by means of connections with a cross piece 45 lwhich consists in a pair of parallel bars 46 and 47 secured to and spaced from each other by the bolts 48 and the spacing sleeves 49 mounted thereon, this construction forming a cross piece having a central slot in which the sup orting or suspending members 50 are free y slidable longitudinally of the cross piece. Each of these supporting members consists of a threaded rod having a flattened circular perforated end 51, this rod being threaded throughout its entire length as shown, and being fsecured in the slot of the cross piece by means of washers 52 and nuts 53.

The cross piece 45 is supported above the carriers 40 by means of distance or spacing pieces 55, each of which hasa smooth central portion 56 which may be cylindrical or may be squared for convenience in holding it, while the ends are threaded right and left handed to receive nuts 57 for engagement with the cross piece and similar nuts 58 which secure the distance piece to the bracket end 42 of carriers exactly similar to those previously described, all of these nuts being provided with the usual washers.

lVhile it is not intended that the cross piece should ever be arranged other than parallelto the upper faces of the carriers, it will be noted that the carriers may be arranged at different distances from the pivots of the arms, and since the distance pieces 55 are cylindrical, and therefore have a pivotal engagement with both the cross piece and the carriers, the cross iece may be arranged at any desired ang e to the arms. It will usually not be necesary to thus angle .the cross piece since in normal operation it will be arranged parallel to the plane of the flange of the gear housing and the sup orting members 50 will be'adjusted vertical y and horizontally so that the per-` is perforated at its lower end to receive the shaft of a bolt 66 having a solid integral head 67. This bolt 66 is threaded through a bridge member 70 clamped to the beams 17 by means of the thumb screws 71 and the bolt or adjusting member 66 is provided with a small handle` 724 at its end so that it is not necessary to carefully adjust the distance between the two pedestals, since by securing the bridge 70 and by turning the handle 72, the movable pedestal may readily be brought to the exact location desired.

When the frame A is moved so that the bars 32 are vertical it-might appear that a very great stress was thrown upon the four set screws 41. This however, is not the case as, due to the pivotal connection of the vdistance pieces 55 with both the cross-piece
