CLARENCE D. SHEPPARD, OF MILWAUKEE, WISCONSIN ANCHOR AND snrron'r r03 cononn'rn noAn ronms,

Application filed December 29,1919. Serial ,No. 348,092.

' To all whom it may concern:

Be it known that I, CLARENCE 'D. SHEP- PARD, a citizen of the United States, and

resident of Milwaukee, in the county of Milwaukee and State of lVlsconsm, have invented certam new and useful Improvements in Anchors and Supports for Concrete-Road Forms; and I do hereby declare that the following is a full, clear, and exact description thereof. I

My invention relates to new and useful improvements in means for anchoring rails or like members directly to" the ground,-and is more particularly directed to the provision of means for supporting and anchoring .concrete road forms which are of the relatively heavy type adapted to support the wheels of a tamping or other machine which it may be desired to propel over the forms incidental to the completion of said road- 7 way.

It is in general the object of my invention to simplify and strengthen the structure and to increase the holding efficiency of devices of this character.

I Concrete road forms which are in the form of sheet metal rails of sufficient height "to hold the proper amount of concrete for the roadway, are liable. to tilt and settle upon the application of wheeled load thereon,' and it is more particularly my object to i provide an arrangement whereby the stakemember of the anchoring and supporting device engages the form in such manner as to obtain a maximum holdlng action on the form.

It is further my object to provide a comparatively simple arrangement for locking the stake member to the form when said stake member has been driven into the ground to its proper position. 7

With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of the parts as hereinafter described and defined by the appended claims.

Figure 1 is a vertical sectional view through a concrete road form showing my improved anchoring and supporting device associated therewith and having parts broken away to more clearly disclose the structure.

1 portion bent to provide a ground engaging footflange 6 whereby the intermediate por-. tion of the plate may be disposed vertically on edge, and having its other side portion bent laterally to provide a top flange 7 on which the conventionally shown wheels 8 of a tamping" machine are adapted to travel.

The flange portions of the plate are directed outwardly from the road bed, and the concrete' material 18 adapted to engage against and be held by the intermediate portion 5 of the form plate. 1

In associating my improved anchoring and supporting device with the structure described, I preferably secure a reinforcing plate 8'to' the vertlcal intermediate portion of the form plate, thelower end of this reinforcing plate being bent to lie over the foot flange 6, and said flange and end portion are provided with registering apertures for the reception of a stake member 9, said apertures being located approximately'at the juncture of the foot flange and bodyport ion' of the form. A channel member is provided for guiding and holding the stake'and this channel member is formed in the present instance of a plate of metal l0'bent intermediately upon itself with its side portions against tilting and settling stresses exerted extending in parallelspaced relation and then turned outwardly and secured by rivets 10 passed therethrough and through the reinforcing plate 8 and through the vertical side of the form. Inasmuch as the stake 9 is T-shaped in cross section, the channel plate is shaped to afford a corresponding T-shaped cross section, and the head of the channel is inclined inwardly toward its lower end whereby the stake upon being in serted therein is guided so as to enter the ground at a definite inclination. This oblique inclination of the stake provides clearance thereof with respect to the top flange 7 of the concrete form, and also serves to procure a more effective anchoring and supporting action since the tendency of the form is to tilt outwardly under road strain of the concrete roadway.

For. positively locking thestake 9 in position', after the same has beendriven into .the ground, the side portions of the platelO are provided with slots 11 communicating with the channelway of the plateand adapt-,

ed to receive a wedge key 12 for engagement withthe adjacent portion of the stake.- Said slots and the wedge key extend horizontally,

and thus by reason of the oblique exten- 'may be most readily manipulated to procure firm and permanent support. and anchorage GlIGCtlVG particularly to overcome the Settling and tilting stresses to which a concrete road form would be SLlbjGQilGClWhQll used as the. supporting rail for a machine traveling over the form. a

While I have shown and described a preferred embodiment of my invention, it will be appreciated that various changes and modlficatlons of structure may be employed 7 to meet differing conditions of use and manufacture, without departing in anymannor from the spirit of my invention.

What is claimed is: 1 I

1. The'eombination with a road formhaving a lateral supportfoot, of a channel member secured to the form and inclined downi wardly and inwardly toward the uncture of said lateral foot with the body of the form and a stake member insertible in saidchannel. i V

' 2. The combination with a road form havit ing a lateral support foot, of achannel memher secured to the form and inclined downwardly and inwardly toward the uncture of said lateralfoot with the bodylcit' the form, a stake Vmember insertible in said, channel.

and means for locking the stake member in the channel. g V i 3. The combination with aroad form of a in said slots for biting channel member secured thereto and provided with a'slot intersecting itschannel, a stake member insertible in the channel and awedgejkey insertible in 'the'slot for engagement with the stake member, within the channel to lock said stake member against movement. 1

l. The combination with a road'form having a lateral support foot of a channel member formed 'of'a sheet of metal intermediately bent to provide a channel adjacent its bent portion, said channel-being inclined downwardly and inwardly toward the junc-, ture of the iateral 'foot with the'body of the form, theedge portions of said sheet of metal being secured to the body of the form and {a'stalre member insertible' in the channel.

T he combination witha road form having a' later'al support foot'of a channel mem-- ber formed of a sheet of metal intermedi- "ately bent to deiin ea channel, T-shaped in cross section,th e edgeportion of the plate being secured to the body of the form and stake member of T-shaped cross section insertible 111 said channel.

6. The combination with a road form having a lateral support foot of a channel member formed of a sheet of metal intermedi ately 'be'nt to define a channel, T-shaped in cross section, the edge portion of theplate' being secured to the body of the form the head portion ot said channel being inclined downwardly and inwardly toward the une- "ture'of the lateral toot with the body 01 the form, opposedportions of said sheet being )royided with slots, a stake member T- shaped incross section and insertible in the channel, and a wedge key member insertible In testimony that I claim'the foregoing I e g e twith the stake member. 1

have hereunto set my hand at Milwaukee, in

the county of Milwaukee and State of VVisconsin.
