AARON T. ROSSIGNOL, OF WASHINGTON, DISTRICT COLUMBIA.

COMBINATION TOOL.

Application filed October 7, 1920. Serial No. 415,411.

To all whom it may concern Be it known that I, AARON T. RossIoNoL, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Combination Tools, of which the following is a specification.

My said invention consists in a tool stock having means for holding various tools in place thereon either singly or in combination with others.

It is an object of my invention to provide a tool stock that shall have means to hold in absolutely rigid position tools and appliances of widely varying nature and having different purposes.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a side view of my tool stock,

Figure 2 a sectional view showing some parts in elevation.

Figure 3 a transverse section on line 3-3 of Flgure 2,

Figure 4 a side view of an extension that may be attached to the stock as shown in Figure 1 by dotted lines.

Figure 5 shows the lower end of my tool stock in workin position, with metal boring tools in position thereon,

Figure 6 shows a modified form of the metal boring attachment,

Figure 7 shows a similar view of my tool stock arranged as a valve-seat reamer,

Figure 8 shows a partial vertical section thereof,

Figure 9 shows a transverse section on line 99, of Figure 8,

Figure 9 shows my tool stock fitted as a combined boring and countersinking device,

Figure 10 shows my tool stock fitted with a milling cutter and co-acting devices;

Figuresll, a partial longitudinal section of the same,

Figure 12, a vertical section on line 12-12 of Figure 11; Y

Figures 13 and 14, attachments which are used to hold in place the milling cutter shown in Figures 10 to 12,

Figure 15 shows my tool stock fitted up as a counter-boring tool for woodworking; and

Figure 16 a partial vertical section of the same.

In the drawings 20 indicates a tool-stock having a shank portion 21 screw-threaded thereto, and locked in place by a screw plug 22, and a forward extension 23 internally screw-threaded at 24.

An extension 25 may be placed-at the upper end of the shank member as indicated in dotted lines in Figure 1, the dotted lines at 26 in extension 25 indicating a stock for receiving the shank and the dotted lines at 27 indicating a bar which may be used for turning the stock. At 28 is a slot into which a wedge may be driven to separate the shank from the extension. The stock has a central aperture or bo-e 29 in which is a pin 30 tapered at its lower end and which may be of uniform size throughoutor may have a reduced portion near its lower end as shown in-Figure 2. The stock also has a transverse orifice 31 and a seat 32 to receive tools. The orifice 31 is shown as rectangular to co-act with certain tools hereinafter described. It may be made of any desirable and convenient shape for various purposes. A sleeve 33 surrounds the stock and has screw threaded engagement therewith. This sleeve has a threaded opening which may be closed by a screw plug 34 and which communicates with an internal groove 35, the screw plug being hollow ground to form a continuation ofthe groove. This groove in turn communicates with a slot through the stock as indicated in dotted lines in Figure 2'and a hole through pin 30 as shown in Figures 2 and- 3. A: transverse pin 36 is inserted through-the hole in the sleeve and into the openings in the stock and pin. The sleeve 33 may have roughened portions and-hexagonal portions for convenience in turning it and when' turned will travel along the stock by reason of its screw threaded engagement therewith. Because of the engagement of the edges of the groove 35 with the ends of pin 36 the pin will travel up and down with the sleeve and will carry with it the pin 30.

Figures 5 and 6 illustrate the stock used in connection with metalworking tools. In these figures a bar 37 car ing the counter boring tool 38 is inserted 1n the orifice 31. A drill 39 is threaded in opening 24 and may act as a guide when the counter boring tool is in action, if desired, or a different guide may be substituted therefor after a h le has been bored with the drill. In his device bar 37 is simply locked between the pin and the lower end of the orifice 31. 40 and 41 indicate a pair of bars which may take the place of 37 andwhich may each hold a counter boring tool.

It will be evident that the bars shown in Figures 5 and 6 could be held in place within the scope of this invention b means other than pin 30 such as will herelnafter be described in connection with Figures 10 and 11. Figures 7, 8 and 9 illustrate the use of my tool stock in connection with a reamer for valve seats such as the valve seats in automobiles. For this purpose I use a guide rod 42 which engages the screw threaded opening 24: and the base of which rests against the end of the stock and assists in holding the reamer 43 in place. This reamer also rests against the seat 32 and has an upwardly extending portion which is grooved as indicated at 44. Balls or rollers 45 are placed within the orifice 31 and are forced outward by the tapered portion of pin 30, the balls having a three point engagement with the pin, the lower wall of orifice 31 and the upper edge of the groove in the reamer 7 whereby they act at the same time in an upward and outward direction to lock the reamer securely in place.

Figure 9 illustrates the stock fitted as a device for boring and countersinlring a hole in a single operation. The parts are the same as in Figure 8, save that a drill 39 is substituted for the guide 42. y

In Figures 10 and 11 T have illustrated a milling tool 4:6 in place on my tool stock. The milling tool surrounds the stock near its lower end, a collar 47 being placed between the sleeve 33 and the milling tool. A key member 48, Figure 1A, is placed. inside the orifice 31 and engages with its reduced portion 48' a key-way A9 of the tool. A collar 50 having a groove to engage the reduced portion of the key is placed next to the tool and a filler plug 51, Figure 13, is placed in the orifice between the collar 50 and the lower wall of the orifice. This filler has shoulders to engage over the sides or" the stock. The sleeve 33 is now turned to force collar 47, tool 4-.6. collar 50 and plug 51 downwardly toward the end of the stock whereby they are securely locked in the position shown in Figure 11. A protector center 59 may be inserted in the threaded opening 3 1 if desired. The device as shown in Figures 10 to 14 may be used by hand, in an electric drill, in a lathe, a drill press or an ordinary milling machine according to the nature of the work and the facilities of the shop.

Figures 15, and 16 illustrate my device fitted as a counter boring tool for woodwork ing. As here shown a tool carrier 52 shaped to act as a cutter and having an inclined edge and two sides perpendicular to each other is arranged in the orifice 31, A block 53 with a corresponding inclined edge and three fiat surfaces is also placed in the orifice, the inclined edges registering as shown in Figure 16. The pin 30 is then brought down on member 53 looking it and member 52 firmly in place. A guide member 5% surrounds the lower end of the stock and engages seat 32, this guide member having a threaded portion 55 and a guide portion 56 counter bored to receive a screw 57 which engages with the threaded opening 24 to hold the guide in place. lit will be evident that a collar such as 47, Figure 11, could be utilized to hold the

parts

52 and 53 in place in Figure 15 or to hold the

bars

37, 40 and 41, Figures 5 and 6. Similarly, a screw such as 57 could act as the locking device in Figures 5, 6 and 11.' In such a modification the screw would engage opening 24, its end passing through and acting to lock in place devices placed in the orifice 31. the end of the screw being tapered if desired.

In using my device as a counterboring tool, it may bore a hole in wood at any angle. By the use of this device ll am enabled to dispense with the heavy angle washers such as are commonly used in holding together timbers, since the counterbore is directly in line with the hole, the feed die guiding the counterboring tool accurately to "follow the hole. An ordinary flat washer may then be utilized in the bottom of the counterbored portion to support the head of the bolt passing through the hole, or a nut on such bolt.

Various other modifications will suggest 100 themselves to those skilled in the art and it do not limit myself to the particular mechanism shown in the drawings the true scope of my invention being indicated by the appended claims.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is:
