Patented Aug. 6, 1935 *PATE NT oFFlcE vDRIVING: DEVICE FOR 'MAKING `CAST CON- CRETE `PILE PLANK-INGS `IN `SUBSOIL Hermann Stechert, Grafenlhazinichen,Germany Application January 13, 1933, Serial No.` 651,538
' VIn Germany January 19, 'i932 The nature of this invention relates to certain new and useful improvements in that class of devices employed for making cast concrete pile plankings in subsoil; and theinvention consists in the peculiar construction of a so-called driving element in connection with such making of pile plankings in concrete or reinforced concrete having a cross-section of from 5 to .15`centimeters. The main object of the invention is to provide a driving device having-a passage for receiving the liquid concrete andmounted in said passage a casing, the saidcasing being guided in said passage --telescopically and carrying fixed to it the central part of the cutting edge of said driving element, which central part is adapted for displacement in downward direction.
Another object of the invention consists in the provision, in said casing, of guide surfaces and of outlet openings for the concrete to be discharged; and still another object of the invention consists in the provision of a pin-like projection or spur positioned at the side of the device. The inv ention relates also to improvements in various other parts of the device, Vall hereinafter fully described, and more particularly pointed out in the claims.
With the above recited and other objects in view,` reference is had to the following specincation and drawing, in which there is exhibited one embodiment of the invention, which is in no way intended as a limitaton upon the scope of the appended claims, as it is to be clearly understood that variations and modifications which properly fall within the scope of said claims, may be resorted to when found expedient.
In the drawing:- Y
Fig. l is a horizontal section taken on line l--l of Figure 2 through the upper part of the driving device according to the invention;
Fig. 2 is an elevational viewof the driving device in the position of ram, the cutting edge being closed; i
Fig. 3 is an elevational view of the driving device in operative position, the cutting edge being opened;
Fig. 4 is a vertical cross-section, taken on line 4 4 of Figure 2; and
Fig. 5 is a vertical cross-section, taken on line 5--5 of Figure 3. i
Referring to the drawing, the reference character a denotes the driving plank m'ade 0f wood or other suitable material, and b designates the l,
iron-plated part at the upper end ofthe said driving element, which is provided with a central passage c, adapted for the reception of liquid convably the shape of structural iron crete when the driving element proper is`being drawn back. At uthe side of the device, there is disposed la pin-like projection or spur, as at d, this. projection having for its function to draw, during the ram driving action, the body of the driving member in close proximity to the body of the pile planking that has been just cast and which `is Aoccupying the adjacent position, and having furtherior its oiiice to prevent, on the driving elementbeing drawn back, the still liquid concrete of said adjacent plank from breaking out-and'gettingunder theraised driving element. The reference character-f `designates a 'casing made of strong sheet'metal and 'telescopically guided within the passage c, the said casing forming a part of the ram shoe proper. The lower part of said casing, which forms a wedge-like cutting edge, is at its central portion constituted by a block e of cast steel to which the sheet metal of the casing is riveted. The wedge e, f, is reinforced by means of a steel plate q made somewhat' stronger than the said sheet metal of the casing, and fastened thereto in any suitable manner. VSaid casing has at its lower half, and at opposite sides, the material cut out Vso as to obtain two lateral openings, as at g these openings allowing ldischarge of the liquid concrete at the moment when said wedge is inV end position, and on the device being lifted, as shown in Figure 5.
The arrangement is made so that the impact imparted by the monkey to the driving device, is being .entirely transmitted to the member ',f. This transmission of impact action is accomplished, on the one hand, by the parts h undercut at right angles and provided for this purpose, and on the other hand, by a rail i having prefer-- and which may be riveted or welded to said shoe. In addition Vto this, the said casing is provided with inclined guide surfaces 7c for the concrete to be discharged. Further, the middle portion of said Y driving element is iron-plated, as at l, and rmly connected to the iron-plated head-portion b of said element, and to the ram shoe, respectively. The casing f is in connection with the driving `device by means of two pairs of cross bolts m and n, respectively, the former being made removable so 4as to allowtheir withdrawal at the beginning of the operation, and the latter being adapted for freedom of movement in guide slots o, which are vertically disposed. The said crossbolts n are also loosely accommodated, but positioned countersunk, and a space has been left between each of their heads and the outer surface of the body .of the device, the said spaces being each intended for the reception of a plate p flush with said outer surf ace and having the function to firmly retain sai-d bolts 1L on their seat. Preferably, the said plates p are displaceably connected to the body of the device so as to allow access to said bolts n, if necessary.
In the position of ram, the telescopically mounted casing f shuts off the passage c of the driving element. On the lifted operation of said element, the concrete which has entered said pas sage, is discharged through the laterally dispose-d openings g, the guide surfaces lc provided for, facilitating the said discharge. In the position of operation, the upper bolts m are withdrawn, whereby the shank of the driving member is caused to repose upon the casing f. On the driving element being drawn backward, the casing f is displaced in downward direction to an extent corresponding to the length of the guide. slots o, until said displacement be stopped by the lower cross bolts n. In consequence of this downward movement, the lateral openings g become unmasked, and the liquid concrete is discharged through the said openings into the space left by the lifted driving member.
It is to be understood that the lower bolts n might be disposed eXteriorly for the convenience of obtaining a smooth -discharge of the concrete.
The driving device may be operated upon by any suitable ram impact machinaand it allows uninterrupted working owing to the pin-like pro je'ction d preventing breaking out of the concrete from the concrete body placed just before and not yet entirely solidified'.
I claim:
1. A driving device for making concrete pile plankings in subsoil comprising a driving niember proper having a centrally disposed vertical passage therein, a casing provided with a cutting edge on its lower end telescopically mounted in the lower portion of the passage, means in the passage limiting the up and down movement of the casing, lateral openings in the lower end of the casing directly above the cutting edge, inclined surfaces in the easing adjacent the openings adapted to guide and discharge liquid concrete through the openings from the vertical passage, and a pinlile projection on the lower end and at one side of the driving member proper.
2. A driving device for making concrete pile plankings in subsoil, comprising a driving member proper having a centrally disposed, vertical passage therein, a casing accommodated in said vertical passage, acutting edge mounted on the lower extremity oi said casing which is telescopically guided in the lower portion of said passage, two pairs of cross-bolts adapted to secure the said casing to said driving member and to limit the up and down movement of said casing, two lateral openings provided at the lower hali of said casing which, at its end portion, is formed to updirected, Wedgehape-d body for guiding and discharging liquid concrete through said lateral openings, and a pin-like projection on the lower end and at one side of th-e driving member proper.
